Idaho concrete license requirements.

Idaho does not license concrete contractors. The Idaho Contractors Board, inside the state Division of Occupational and Professional Licenses, instead requires every concrete, foundation and masonry contractor to hold a state contractor registration once a job reaches $2,000. There is no trade exam. Proof of $300,000 single limit general liability coverage is the headline requirement.

Who regulates concrete work in Idaho

Concrete work in Idaho sits under the Idaho Contractors Board, which operates inside the Idaho Division of Occupational and Professional Licenses. The board was created by the Idaho Contractor Registration Act, Title 54, Chapter 52 of the Idaho Code, and registration became mandatory on January 1, 2006. The statute defines construction as building, altering, repairing, adding to, subtracting from, improving, reconstructing, moving, excavating, wrecking or demolishing any building, highway, road, bridge, or other structure, project, development or improvement to real property. Footings, stem walls, slabs, driveways, sidewalks, curb and gutter, retaining walls, and block and brick work all land inside that definition. The same chapter defines a contractor as any person who undertakes, offers to undertake, purports to have the capacity to undertake, or submits a bid to perform construction, or who performs it through others. Submitting a bid is enough to put you under the board's jurisdiction. The board has five members appointed by the governor: four contractors and one member of the public at large. The division handles applications, renewals, complaints and discipline on the board's behalf, and publishes BCRE-Licensing@dopl.idaho.gov and (208) 334-3233 as its contact points. Idaho has no separate concrete board, no masonry board and no flatwork board. The division's own roster of building and construction boards lists Contractors, Public Works Contractors, Building Code, Electrical, Plumbing and HVAC, with nothing specific to concrete. One state credential therefore governs the crew pouring a patio in Coeur d'Alene and the crew forming a commercial foundation in Idaho Falls.

Registration is not a license, and that changes how you sell

The division states it plainly: the Idaho Contractor Registration Act requires registration, not licensure. That distinction shapes how a concrete contractor has to win work here. Idaho does not test your ability to place, finish or cure concrete. The board does not review your mix designs, your reinforcing layout or your joint spacing. What the application asks for is identity, ownership, insurance and a clean disciplinary history. The application is submitted under oath and must carry your Social Security number or employer tax identification number, the name and address you do business under, the name and address of every principal, member, partner or shareholder claiming an ownership interest, proof of workers compensation coverage or a statement explaining why it is not required, a certificate of general liability coverage, a statement of the type of construction you intend to undertake, and a statement about any contractor license or registration ever denied, surrendered or revoked in this or any other state. If a denial or revocation exists, you explain it. An application the board denies becomes a contested case under Title 67, Chapter 52 of the Idaho Code. The practical result is that your registration number tells an Idaho homeowner you carry insurance and that the state knows who owns your company. It does not tell them you can pour a flat slab that stays flat. The board's stated purpose is to give the state a way to remove incompetent, dishonest or unprincipled construction operators after the fact, not to screen them out beforehand. Photographs of finished pours, named references and written warranty terms do the screening work the state skips.

The $2,000 trigger and the exemption list

Registration bites once a single undertaking or project, whether under one contract or several, carries an aggregate contract price of $2,000 or more for labor, materials and all other items. Below that figure the statute treats the job as casual, minor or inconsequential and exempts it. Two guardrails sit on that exemption. It does not apply when the work is part of a larger construction project, whether that larger project is run by you or by someone else. It also does not apply when an operation is divided into contracts under $2,000 to evade the chapter. A concrete sub pouring footings as part of a house build is working on a larger project, so the $2,000 floor does not help. Other exemptions are listed in the act. Employees paid wages or salary by a contractor are exempt, but subcontractors and independent contractors are not. Suppliers who furnish materials without installing or fabricating them are exempt. Government representatives, regulated public utilities doing work incidental to their own business, farmers and ranchers in farming operations, and persons building an agricultural building exempt from the Idaho building code act under section 39-4116 are all outside the chapter. An owner performing construction on personal residential real property is exempt, as is an owner who hires a registered contractor, but the exemption fails for an owner who builds intending to sell during construction or within twelve months of completion. Anyone already licensed under another Idaho chapter stays exempt within the scope of that credential. No exempt person may hold himself out as a registered contractor. One more duty runs the other way: it is unlawful to engage another contractor who must be registered unless that contractor furnishes satisfactory proof of registration.

One registration, no concrete or masonry classification

Idaho does not break contractor registration into trade classifications. There is no concrete class, no flatwork class and no masonry class to apply for. The application asks for a statement of the type of construction you intend to undertake, or whatever else the board requires by rule, but that statement does not fence you in the way a classification system in another state would. A registered Idaho contractor who pours slabs, forms foundations, lays block, sets pavers, saws existing concrete and does the excavation that goes with all of it works under a single registration number. On approval the board issues a certificate of registration plus a wallet sized card showing the registrant's name and registration number. Certificates are neither assignable nor transferable, so buying another concrete company does not buy its registration. On any change of ownership or change of address the entity must notify the board within thirty days. There is one useful crossover. A person granted a public works contractor license or a construction manager license receives a certificate of registration without paying a registration fee, provided the Idaho licensure requirements are met. The division's guidance adds that a public works licensee or construction manager may register to cover construction outside the scope of that license and is exempt from the fee. Going the other way, holders of other Idaho credentials such as electrical contractor, plumbing, engineering, surveying or manufactured home installer do not register at all unless they contract beyond the scope of what they hold. For a concrete contractor the takeaway is simple: one number, no class upgrades, and no additional state paperwork for adding masonry or excavation to what you sell.

Insurance: the $300,000 general liability floor

Insurance is the real substance of Idaho contractor registration. The act requires a certificate issued by an insurance company authorized to do business in Idaho showing that the applicant has procured and has in effect a general liability policy, including products and completed operations coverage for the applicant's construction operations, in the sum of not less than $300,000 single limit. Completed operations matters for concrete. Cracking, settlement, scaling and spalling typically surface after the crew has left, which is exactly what completed operations coverage responds to. The act also shields the policy data: the name of the insurance company, the insured and the policy number are made available only to persons or their insurers who state that they possess a claim against the contractor. Separately, the application must include a certificate from an authorized insurer or other satisfactory proof that the applicant has workers compensation insurance in effect, or a statement from the contractor explaining why that certificate or coverage is not required. The Idaho Industrial Commission, which regulates workers compensation in the state, states that most employers are required to carry coverage for their employees, and it runs a public tool for verifying an employer's coverage. Letting coverage lapse is a registration problem, not just an insurance problem: the division's guidance names failure to provide workers compensation or liability insurance as a ground on which a registration can be revoked. Treat $300,000 as the state floor and nothing more. General contractors, commercial property owners and public agencies routinely require higher limits, additional insured endorsements and certificate holders named on the policy before a concrete sub is allowed on site.

What registration costs

The board publishes its contractor registration fee schedule on its own page. For the schedule marked effective July 1, 2026, both individual and business registrations carry an application or initial fee of $120. Annual renewal is $60 and biennial renewal is $120. A reinstatement fee of $40 applies in addition to the renewal fee when a registration has lapsed. The statute sits above those numbers as a ceiling. Section 54-5210 of the Idaho Code says the applicant submits a registration fee as set by the board to cover its administrative and enforcement costs, not to exceed $150 per year. Reciprocal registration carries its own cap: a fee not to exceed $50, as determined by board rule, for the administration and processing of that kind of application. There is no exam fee for contractor registration in Idaho, because there is no exam. There is no bond to post with the board, no net worth test and no financial statement to file, which is a meaningful difference from the public works license covered further down this page. Registration is also free to one group. A certificate of registration is issued without payment of a registration fee to any person granted a public works contractor license or a construction manager license, so long as the Idaho licensure requirements are met. Active military members may qualify for a waiver of renewal fees and other renewal requirements under section 67-2602A of the Idaho Code. Fee schedules change, and the board has been moving renewal cycles, so confirm the current figure on the board page before you budget a renewal. The board takes applications and renewals through the division's online services system.

Renewal, inactive status and the move to biennial cycles

Idaho has been changing its renewal rhythm, so read the board page before you assume a date. The statute allows a registration to be issued for a period of not less than twenty four months and not more than five years, as the board determines, with the expiration date printed on the face of the certificate. The board must notify a registered contractor no less than thirty days before the registration expires, and the act asks that the renewal application be filed on or before thirty days prior to the expiration date. The board announced that as of October 14, 2025 it began transitioning to biennial registration, and its published fee schedule now shows both an annual renewal figure and a biennial renewal figure. The older guidance on the board's own FAQ describes initial registrations running twelve months past the registrant's next birthday with annual renewal after that, and renewal notices arriving roughly six weeks before expiration. Contractors caught between those two descriptions should confirm their own expiration date in the division's online services account. Inactive status exists for a crew that stops taking work. A registered contractor not engaging in business may request an inactive registration in writing with the fee set by board rule, issued for twenty four months. An inactive registrant may not contract and does not have to keep the required insurance in force. Converting back to active status requires the fee set by rule plus proof of current insurance coverage. A lapsed registration is reinstated by paying the renewal fee plus the reinstatement fee under board rule, and the act says failure to renew does not deprive a person of the right to renew on a later application. Chapter 52 attaches no continuing education condition to renewal.

Public works: the $100,000 line for concrete contracts

Public concrete work runs under a second and genuinely different credential. Title 54, Chapter 19 of the Idaho Code creates the Public Works Contractors License Board, also administered by the division, and makes it unlawful to engage in public works contracting without a license. The threshold is set by the exemption list. Chapter 19 does not apply to any construction, alteration, improvement or repair involving any single project involving any number of trades or crafts with an estimated cost of less than $100,000. A second exemption covers subcontractors directly: a subcontractor performing work under the direct supervision of a licensed public works contractor holding a Class Unlimited, AAA, AA or A license is exempt if the value of the subcontracted work is less than $100,000. So a concrete sub placing $70,000 of curb, gutter and sidewalk under a Class AAA prime on a city street project does not need the public works license. The same sub bidding a $300,000 slab and foundation package on a school does. Other chapter 19 exemptions reach work on federal land, construction or repair of personal property rather than real property, sale or installation of finished products that are not fabricated into and do not become a permanent fixed part of the structure, irrigation and drainage ditch work for constituted districts, solid waste disposal sites, work under a declared emergency for up to seven calendar days, and licensed architects, engineers and surveyors acting solely in their professional capacity. Government representatives are outside the chapter as well. Note that the public works license and the contractor registration are not alternatives. The chapter 52 registration requirement applies to construction generally, which is why the no fee certificate of registration for public works licensees exists.

The seven public works license classes

Chapter 19 creates seven classes of public works license, each tied to the estimated cost of the contracts the holder may execute. Class Unlimited covers public works involving an estimated cost of more than $5,000,000. Class AAA covers not more than $5,000,000. Class AA covers not more than $3,000,000. Class A covers not more than $1,250,000. Class B covers not more than $600,000. Class CC covers not more than $400,000. Class C covers not more than $200,000. An applicant requesting a Class Unlimited license in heavy, highway, specialty or building construction must show a minimum net worth of $1,000,000 with $600,000 in working capital, which is the only financial test in either chapter. The statute also caps fees by class. The original and renewal fee may not exceed $600 for Unlimited, $500 for AAA, $400 for AA, $300 for A, $200 for B, $150 for CC and $100 for C, and the board fixes the actual amount annually within those ceilings. The fee schedule the board publishes on its own page, marked effective January 1, 2025, lists initial fees of $880 for Unlimited, $720 for AAA, $560 for AA, $400 for A, $240 for B, $200 for CC, $160 for C, and $320 for Construction Manager. Those published figures sit above the per year statutory maximums, and the board has also announced a fee holiday beginning January 1, 2026 along with a transition to biennial licensure that began April 1, 2026. Confirm what you actually owe with the division before you apply. For a concrete contractor the class choice is a bidding decision: pick the class that covers the largest single public contract you intend to execute.

The public works exam and the qualifying individual

The public works license is the part of Idaho contracting that involves a real examination. The division's exam page states that the application and examination process has been updated and that applicants are now required to take and pass the appropriate examination before applying for licensure. Exams are delivered through PSI, with online registration available at the PSI test taker site and telephone support at (855) 340-3713. The division publishes a Contractors' Business and Law Reference Manual as the reference for its exams, and the specific study guide blueprint for each exam sits in the candidate bulletin on the PSI site. Candidates bring their own reference materials. The manual must be printed, hole punched and placed in a three ring loose leaf binder before the exam date. Pre exam highlighting, underlining and permanent indexing are allowed, but no writing is permitted during the session, and additional papers and temporary markers such as sticky notes are confiscated. After passing, the candidate applies for licensure through the division. The statute behind this gives the administrator authority to investigate, classify and qualify applicants by written or oral examination under board rules, and sets the qualifications: a degree of experience and general knowledge of the state's building, safety, health and lien laws and of the rudimentary administrative principles of the contracting business, plus good character. A company qualifies through a responsible managing officer, member or employee rather than the company itself. If the person who qualified by examination stops being connected with the licensee, the licensee must notify the administrator in writing within ten days, and a failure to do so suspends the license automatically at the end of that ten day period. Reinstatement follows an affidavit naming a replacement who has qualified by examination.

Performance and payment bonds on public concrete work

Bonding on Idaho public work is set by the Public Contracts Bond Act inside the same chapter. Before any contract equal to or greater than $50,000 for the construction, alteration or repair of any public building, public work or improvement of the state of Idaho, or of any county, city, town, municipal corporation, township, school district, public educational institution or other political subdivision, public authority or public instrumentality, is executed, the awarded contractor must furnish bonds that become binding on execution of the contract. Two bonds are named. A performance bond in an amount fixed by the contracting body, but never less than eighty five percent of the contract amount, conditioned on faithful performance according to the plans, specifications and conditions, and solely for the protection of the public body. A payment bond, also never less than eighty five percent of the contract amount, solely for the protection of persons supplying labor or materials or renting, leasing or otherwise supplying equipment to the contractor or its subcontractors. Each bond must be executed by a surety company authorized to do business in Idaho, or the contractor may deposit the government obligations listed in section 54-1901 instead of a surety bond. Retainage is capped alongside the bonding rule, and that cap reaches concrete subs directly. Public bodies requiring a performance or payment bond above fifty percent of the total contract amount may not withhold more than five percent of the total amount payable as retainage, and must release retainage for accepted portions of the project within thirty days of acceptance. The same five percent limit and the same thirty day release deadline bind a prime contractor holding retainage from its subcontractors. No bond is required by either chapter for private residential concrete work.

Advertising and license display rules

Idaho is unusually specific about where your registration number has to appear, and this is the rule most often broken by concrete companies that market aggressively. Section 54-5214 of the Idaho Code says a contractor registered under the chapter shall prominently display his contractor registration number for public view in his place of business, on advertising, contracts, permits, company or business letterheads, and purchase orders and subcontracts, within sixty days of issue of registration. The division's guidance restates the same duty and adds the jobsite to the list. Read literally, that reaches your website, your printed estimates, your yard signs, your vehicle lettering if you treat it as advertising, your letterhead, your subcontracts and your purchase orders. There is a second display rule tied to permits. No building inspector or other county, municipal or district authority charged with issuing building permits may issue one without first requesting presentment of an Idaho contractor's registration number, and the number presented must be conspicuously entered on the face of the permit. Where the applicant is exempt, the permit must conspicuously carry the phrase "no contractor registration provided" instead. All permits must then be posted at the construction site so those statements are visible. Wording is restricted as well. Idaho requires registration rather than licensure, so a registered concrete contractor is a registered contractor, not a licensed contractor, and no person exempt from registration may hold himself out as a registered contractor at all. The board may also discipline a registrant for violating the Idaho Consumer Protection Act, with misleading statements given as the example, so advertising claims sit inside the board's reach as well as the attorney general's.

Residential disclosures you owe the homeowner

Idaho puts two written disclosure duties on a general contractor doing residential work, and the contractors board publishes guidance on both. Under section 45-525(2) of the Idaho Code, a general contractor must provide a disclosure statement before entering into a contract in excess of $2,000 with a homeowner or purchaser of residential real property to construct, alter or repair any improvement on residential real property, or for the purchase and sale of newly constructed property. The contractor must also obtain and keep a receipt for that disclosure signed by the homeowner or purchaser. The statement must tell the owner four things: that they may require the general contractor to obtain lien waivers from subcontractors and suppliers at their own reasonable expense; that they may receive proof the contractor has a general liability policy including completed operations plus workers compensation for employees as Idaho law requires; that they may buy an extended policy of title insurance covering certain unfiled or unrecorded liens; and that they may require, at their expense, a surety bond up to the value of the construction project. A second disclosure comes at the end. The board's guidance cites section 54-525(3) and requires a signed statement to the homeowner within a reasonable time before final payment, or before closing on a purchase and sale agreement, listing the business names, addresses and telephone numbers of every subcontractor, materialman and rental equipment provider in direct contract with the general contractor who supplied materials or performed work valued over $500. Those parties may then disclose balances owed. Failure to give the required disclosures is an unlawful and deceptive act under the Idaho Consumer Protection Act, and the board may discipline a registered contractor for that violation. A concrete contractor acting as the general on a driveway and patio package over $2,000 is inside this rule.

Sourcesdopl.idaho.gov

What unregistered concrete work costs you

Idaho stacks four separate consequences on a contractor who works without the registration the act requires, and three of them are commercial rather than criminal. First, no permit. The division's guidance states that a contractor who fails to register cannot obtain a building permit, which follows from the rule that permit issuing authorities must request the registration number and enter it on the face of the permit. Second, no lien rights. Section 54-5208 says an unregistered contractor is denied and is deemed to have conclusively waived any right to place a mechanic's lien on real property under chapter 5, title 45 of the Idaho Code. That section protects innocent parties: a duly registered subcontractor working at the direction of an unregistered contractor keeps its lien rights, and so do employees and material suppliers, as long as they did not actually know the contractor was unregistered or reasonably believed it was registered. Third, no lawsuit. Section 54-5217 bars a contractor who is not exempt from bringing or maintaining any action in any Idaho court to collect compensation for work for which registration was required, without alleging and proving registration at all times during the performance. An unpaid pour becomes uncollectible. Fourth, the criminal penalty. Acting in the capacity of a contractor without a current registration is a misdemeanor punished by a fine not to exceed $1,000, imprisonment in the county jail for up to six months, or both, at the court's discretion. Anyone who acts as a contractor in Idaho, registered or not, has submitted to the jurisdiction of the state and of the Idaho Contractors Board. The parallel penalty under the public works chapter is heavier: acting as a public works contractor without a license is a misdemeanor carrying a fine up to $5,000, imprisonment up to one year, or both, and the same bar on suing to collect.

The city and county layer in Idaho's largest metros

Idaho removed the municipal contractor licensing layer that complicates concrete work in many states. Section 54-5213 of the Idaho Code provides that on and after January 1, 2007, no incorporated municipality, county, alternative form of local government, or other municipal or political corporation or subdivision of this state shall implement its own program for the registration or licensure of construction contractors. Boise, Meridian, Nampa, Idaho Falls, Pocatello and Coeur d'Alene therefore cannot require a city concrete contractor license on top of the state registration. What cities do keep is the permit and inspection function. The City of Boise's Planning and Development Services building division is responsible for issuing building permits and overseeing building construction within the city, and publishes a permit line at (208) 608-7070 and permits@cityofboise.org. Boise also runs an erosion and sediment control program covering construction site pollutants through education, permitting, inspection and enforcement, which is the city program most likely to touch a concrete job with exposed soil, washout and slurry. At the state level the Idaho Building Code Board, also housed in the division, oversees building code matters and publishes inspection, plan review and permit resources, and the division lists bcre-permits@dopl.idaho.gov and (208) 334-3233 for that program. The permit step is where your state registration number becomes unavoidable in every jurisdiction: the issuing authority must request it, enter it conspicuously on the face of the permit, and you must post the permit at the site so that statement stays visible. The authority is not required to verify that an applicant claiming exemption actually qualifies, which puts the risk of a wrong exemption claim back on the contractor.

How customers verify you, reciprocity, and the rest of the paperwork

Verification is public and free. The contractors board links a public search through the division's online services system, where anyone can look up a registration, and the board directs the public to that same search feature for information on formal actions against registered contractors. The public works board links its own license search the same way. For a concrete contractor this matters in both directions: homeowners can check you in a minute, and the act obliges you to obtain satisfactory proof that every contractor, subcontractor or person performing construction you engage is registered. Failing to do that violates the act and can cost you your lien rights, including when you supply or work for someone you know should be registered and is not. Reciprocity in Idaho is narrow and historical. Section 54-5213 lets a contractor submit a verified copy of a current, unrestricted license, registration or certification issued by an Idaho city, county or other local government under an ordinance enacted before January 1, 2007, with a reciprocal fee capped at $50, and the board issues a registration on that basis if the local requirements were not less stringent than the chapter's. There is no listed out of state reciprocity in the chapter. Three other obligations travel with the work. Workers compensation: the Idaho Industrial Commission says most employers must carry coverage for their employees and operates a public coverage verification tool. Tax: the Idaho State Tax Commission treats contractors who build, improve, repair or alter real property as the consumers of everything they use, so a concrete contractor pays sales or use tax on materials, tools, equipment and supplies, including on work done for government entities, and does not charge the customer sales tax on an installed improvement. Selling uninstalled goods makes you a retailer who needs a seller's permit.

What we could not confirm

These are common details other guides publish about Idaho, but we could not verify them from the agency source. Confirm them directly before relying on them.

  • Whether the Idaho Contractors Board imposes any continuing education hours by administrative rule: the statute sets none and no hour figure was found on a primary page, so no number is published here.
  • The exact inactive status fee and the exact reinstatement amount set by board rule for converting an inactive registration back to active: the statute defers both to board rule and no rule figure was fetched.
  • How the Public Works Contractors License Board fee schedule posted as effective January 1, 2025 (for example $880 for Class Unlimited) reconciles with the per year statutory maximums in section 54-1904 (for example $600 for Class Unlimited), and what the announced fee holiday beginning January 1, 2026 changes.
  • Current adopted edition of the Idaho building and residential codes governing concrete footing depth, slab and foundation inspection: not confirmed from a primary page, so no code edition or dimension is stated.
  • Any Boise, Meridian, Nampa, Idaho Falls or Coeur d'Alene permit fee amounts, driveway approach permit thresholds, or right of way flatwork requirements: the city pages fetched did not render these figures.
  • Whether a concrete contractor must register for an Idaho sales or use tax account in every case, and the current Idaho sales tax rate: the state tax guide states the consumer of materials rule but the rate appeared only inside a worked example.
  • Idaho general contractor registration numbers, total registrant counts, or processing times for a registration application.

Idaho concrete licensing questions

Does Idaho require a concrete contractor license?

No. Idaho requires registration rather than licensure. The Idaho Contractors Board, inside the Division of Occupational and Professional Licenses, registers contractors under Title 54, Chapter 52 of the Idaho Code. There is no concrete, flatwork or masonry classification, and no trade exam. Registration became mandatory on January 1, 2006.

At what job size does Idaho registration become mandatory for flatwork?

At $2,000. The act exempts one undertaking or project considered casual, minor or inconsequential whose aggregate contract price for labor, materials and all other items is less than $2,000. That exemption fails if the work is part of a larger construction project, or if a job is split into smaller contracts to evade the chapter.

What insurance does the state make me carry to register?

A general liability policy including products and completed operations coverage for your construction operations, of not less than $300,000 single limit, certified by an insurer authorized to do business in Idaho. You also submit a workers compensation certificate or a statement explaining why coverage is not required for you.

Is there an exam for a concrete contractor in Idaho?

Not for contractor registration. Idaho tests nothing about placing or finishing concrete. An examination applies to the separate public works contractor license, which is now taken and passed through PSI before you apply for licensure, using the division's Contractors' Business and Law Reference Manual.

When does a concrete sub need the public works license?

When the exemptions in section 54-1903 stop covering the work. Chapter 19 does not apply to a single project of any number of trades estimated under $100,000, and a sub under the direct supervision of a Class Unlimited, AAA, AA or A licensee is exempt if the subcontracted value is under $100,000.

Where does my registration number legally have to appear?

In your place of business, on advertising, on contracts, on permits, on company or business letterheads, and on purchase orders and subcontracts, within sixty days of issue. The board's guidance adds the jobsite. Permit issuing authorities must also enter the number conspicuously on the face of the permit.

What happens if I pour concrete in Idaho without registering?

Four things. You cannot obtain a building permit. You waive any mechanic's lien right on the property. You cannot sue in Idaho courts to collect for work that required registration. And you commit a misdemeanor punishable by a fine up to $1,000, up to six months in county jail, or both.

Can Boise or Meridian require their own concrete contractor license?

No. Since January 1, 2007 no Idaho municipality, county or other local subdivision may run its own program for registering or licensing construction contractors. Cities still issue and inspect building permits. Boise's Planning and Development Services building division handles permits and construction oversight inside the city.

How long does an Idaho contractor registration last?

The statute allows not less than twenty four months and not more than five years, as the board sets, with the expiration date printed on the certificate. The board began transitioning to biennial registration on October 14, 2025 and now publishes both an annual and a biennial renewal fee. Check your own expiration date.

What do registration and renewal cost?

The board's schedule effective July 1, 2026 shows $120 application or initial for both individuals and businesses, $60 annual renewal, $120 biennial renewal, and a $40 reinstatement fee on top of renewal. The statute caps the registration fee at $150 per year. Public works licensees get a registration certificate without the fee.

Do I need a bond for residential concrete work in Idaho?

Not under either contractor chapter. Bonds attach to public work: before any public contract of $50,000 or more is executed, the awarded contractor furnishes a performance bond and a payment bond, each in no event less than eighty five percent of the contract amount. A homeowner may separately require a bond by contract.

How does a homeowner confirm my registration is real?

Through the division's public search in its online services system, which the contractors board links from its own page and also points to for formal actions against registered contractors.
