Idaho · Landscaping licensing · official-source guide
Idaho licenses landscaping at state level. The Idaho State Department of Agriculture licenses landscape contractors who furnish or install plants, at $100 for the principal place of business, renewed annually. Separately, the Division of Occupational and Professional Licenses registers any contractor whose landscape construction work reaches $2,000, and the Board of Architects and Landscape Architects protects the landscape architect title.

Idaho splits landscaping oversight between two state agencies and shuts cities out of contractor licensing entirely. The Idaho State Department of Agriculture licenses anyone who grows, sells, imports or installs nursery stock, and its licensing statute names landscape contractors by name. The Idaho Division of Occupational and Professional Licenses runs the Idaho Contractors Board, which registers contractors who perform construction. Idaho Code 54-5203 defines construction as building, altering, repairing, adding to, improving, excavating or demolishing any structure, project, development or improvement to real property. Grading, retaining walls, paver patios, drainage work and outdoor kitchens all sit inside that definition. The Board of Architects and Landscape Architects, also housed at the Division, licenses landscape architects and polices who may use that title. Pesticide application for hire is a separate Department of Agriculture license. Idaho Code 54-5213 bars every incorporated municipality, county, alternative form of local government and other political subdivision from running its own program for the registration or licensure of construction contractors. A Boise crew therefore does not buy a city contractor license on top of the state one. Cities and counties still issue building and plumbing permits, and Idaho Code 54-5209 requires the permit issuer to ask for your Idaho contractor registration number and print it on the face of the permit. When the applicant is exempt, the permit must instead carry the phrase "no contractor registration provided," and the permit has to be posted at the site so that statement stays visible.

This is the license most Idaho landscapers miss. Idaho Code 22-2305 makes it unlawful to engage in the business of propagating, growing, selling, dealing in or importing nursery or florist stock, or to engage in landscape designing, or to act as agent or solicitor for any nurseryman, florist or landscape contractor, without first obtaining a license from the Idaho State Department of Agriculture. The Department states the same rule in plainer words on its Nursery, Florist and Landscaping page: anyone who engages in the installation of landscape plants must first obtain an ISDA license. Idaho Code 22-2302 defines a landscape contractor as any person engaged in landscaping property for which they furnish the plants, trees or shrubs, whether from their own nursery or bought from another. If you sell and plant trees, shrubs, sod or perennials as part of an install, that statute is describing you. The license fee is one hundred dollars for the principal place of business. A nursery with more than one retail outlet must identify the number and location of each on the application and pay an additional one hundred dollars per outlet. Adding an outlet mid year triggers notice to the Department and immediate payment of that one hundred dollar surcharge. An agent license is twenty five dollars per year for each principal the agent represents, and agents who solicit only from other licensees pay no fee. The Department inspects licensed nurseries as often as it considers necessary to detect and control pests and diseases.

The ISDA nursery license runs on a calendar year. Idaho Code 22-2307 requires the renewal fee to be paid with the renewal application before January 1 each year. Any license not renewed by February 1 is assessed an additional twenty five dollar fee on top of the regular license fee. Failing to pay when due forfeits the right to operate as a grower, dealer or agent, and a previously licensed person whose right has been forfeited only gets a renewal by written application accompanied by a sum equal to the regular license fee. There is one narrow exemption. Idaho Code 22-2305 does not apply to sales of plants, shrubs, scions or florist stock by a person not regularly engaged in that business, where the sales are only incidental to farming or gardening and total gross annual sales do not exceed five hundred dollars. A working landscape company clears that ceiling on a single front yard, so plan on licensing. Two display rules come with the license. The license number must be prominently displayed in each outlet. Idaho Code 22-2311 then bars any person from advertising plant material covered by the chapter in any media without disclosing the company name or the license number. That reaches your website, your yard signs and your plant lists, not just a storefront. The Department can inspect nursery stock held by an exempt seller whenever it suspects a pest concern or a quarantine violation.

Idaho does not issue a trade license for landscaping construction. It registers contractors. Idaho Code 54-5204 makes it unlawful for any person to engage in the business of, or hold himself out as, a contractor in Idaho without being registered, and it is equally unlawful for a registered contractor to engage another contractor without satisfactory proof that the other firm is registered. General contractors asking you for your registration number before they let you on a site are following that subsection, not being difficult. The number that decides whether you need to register sits in the exemption list. Idaho Code 54-5205 exempts a person performing work on one undertaking or project considered casual, minor or inconsequential, whether by one or more contracts, where the aggregate contract price for labor, materials and all other items is less than two thousand dollars. The same paragraph closes the obvious loophole: the exemption does not apply when the work is part of a larger construction project, whether run by the same or a different contractor, or when one job is split into contracts under two thousand dollars to evade the chapter. For a landscape crew, that means a one off two hundred dollar shrub swap is exempt, while a patio and irrigation package on a new build is not, even if you bill it in stages. Registration is with the Idaho Contractors Board at the Division of Occupational and Professional Licenses, and anyone acting as a contractor submits to that board's jurisdiction whether or not they registered.

Registration is paperwork and insurance, not an exam. Idaho Code 54-5210 lists what the application must carry: a tax identification number or social security number, the name and address the applicant does business under, the name and address of every principal, member, partner or shareholder with an ownership interest, a statement of the type of construction to be undertaken, and a disclosure of any contractor license or registration ever denied, surrendered or revoked in any state. Two insurance items follow. The applicant must supply a certificate showing worker's compensation coverage in effect, or a statement explaining why coverage is not required. The applicant must also supply a certificate from an insurer authorized to do business in Idaho showing a general liability policy in effect, including products and completed operations coverage, in the sum of not less than three hundred thousand dollars single limit. The statute caps the registration fee the board may set at one hundred fifty dollars per year. The Idaho Contractors Board publishes its current schedule, effective July 1, 2026: application or initial registration is one hundred twenty dollars for an individual and one hundred twenty dollars for a business, annual renewal is sixty dollars, and biennial renewal is one hundred twenty dollars. Reinstatement adds forty dollars on top of the renewal fee. The board began transitioning to biennial registration on October 14, 2025. Idaho Code 54-5211 sets registration terms of not less than twenty four months and not more than five years, with the expiration date printed on the certificate and a notice from the board at least thirty days out.

Idaho Code 54-5205 is long, and several paragraphs decide whether a landscaping business registers. Employees are exempt: a person who only performs labor or services for wages or salary as an employee of a contractor needs no registration of their own, but that exemption never extends to a subcontractor or other independent contractor. If you hire crews as 1099 subs, each sub needs its own registration. Farmers and ranchers engaged in farming, dairying, agriculture, viticulture, horticulture or stock operations are exempt, which is why a nursery growing its own stock can sit outside the chapter while its install division does not. Irrigation districts, canal companies, water districts, drainage districts and other water delivery or water management entities are exempt, and so are their operating agents, so district work follows district rules. Material only suppliers are exempt when they do not install or fabricate what they sell. Commercial property owners and their lessees may perform maintenance, repair, alteration or construction on their own properties with their own employees. Owners performing construction on their own personal residential real property are exempt unless they are building to flip, and the anti flip language in paragraphs (k) and (l) requires twelve months of continuous occupancy as a primary residence before a sale. The chapter also exempts people already licensed under other Idaho professional chapters, including landscape architects, so long as they are not acting to evade the chapter. No exempt person may hold himself out as a registered contractor.

Idaho protects the words, not just the work. Idaho Code 54-3003 states that no person shall use the designation landscape architect or landscape architecture, or advertise any title or description tending to convey the impression that the person is a landscape architect or practicing landscape architecture, unless that person is licensed. Every license holder must display it in the principal office, place of business or place of employment. The exemption in the same section is the one landscaping firms should read closely. None of the chapter applies to the business conducted in Idaho by a land use planner, horticulturist, nurseryman, landscape nurseryman, gardener, landscape gardener or landscape contractor, as those terms are generally used, including their right to plan and supervise, except that no such person may use the designation landscape architect or landscape architecture or any description tending to convey that impression. So you may design and plan plantings and sell design build packages as a landscape contractor. You may not call the result landscape architecture or your designer a landscape architect. Idaho Code 54-3002 defines landscape architecture broadly, covering consultation, investigation, planning, design and responsible supervision in land development where the dominant purpose is land use, natural land features, ground cover and planting, approaches to buildings, natural drainage and inherent land problems such as erosion. It expressly includes pools, walls, steps, trellises and canopies that are incidental and necessary, and expressly excludes the design of habitable or industrial structures and the making of final land plats for recording.
Idaho Code 54-3003 sets three qualification tests. An applicant must be eighteen or older, must have graduated from a college or school of landscape architecture approved by the Board of Architects and Landscape Architects or instead present evidence of at least eight years of experience or education in landscape architecture of a grade and character satisfactory to the board, and must pass a board approved examination. The written examination must establish competency to plan, design, specify and supervise the installation and construction of landscape architectural projects, and the board may add oral examination. The board may approve an applicant who holds a current Council of Landscape Architectural Registration Boards certification, or, with limited examination, an applicant licensed in another state or country with requirements at least substantially equivalent to Idaho's. The statute caps the application fee at two hundred dollars and the original and biennial renewal license fee at four hundred dollars. The board's published schedule is lower: initial license one hundred dollars, endorsement one hundred dollars, annual renewal fifty dollars, biennial renewal one hundred dollars, application fee twenty five dollars, reinstatement thirty five dollars, and landscape architect in training twenty five dollars. The board must adopt rules requiring continuing education on a biennial basis. Licenses are issued to individuals only, though a licensee may render services for a firm. One detail matters to anyone opening a design office: a person applying to a county or city for a business license to practice landscape architecture must show that official a current Idaho license before the business license is granted. Every licensee carries a board approved seal reading Licensed Landscape Architect, State of Idaho.
Spray a client's lawn for money and you are in a different licensing chapter. Idaho Code 22-3404 says no person shall act as a professional applicator without first obtaining a professional applicator license from the Idaho State Department of Agriculture. An applicant must be at least eighteen, must pass the Department's examination covering how to apply, use and handle pesticides in the areas of work intended, and must show proof of financial responsibility set by rule. The Department's category list includes Ornamental Pest, written for professional applicators who use or supervise the use of pesticides to control pests in the maintenance and production of ornamental plants and turf, and Right of Way Pest for roadsides, powerlines, pipelines and similar areas. Two exemptions in the statute matter to small crews. A person applying pesticides other than restricted use products for himself or on an exchange of service basis, who does not publicly hold himself out as a professional applicator, is exempt. So is a person using hand powered equipment to apply pesticides other than restricted use products to lawns or to ornamental trees and shrubs, who employs two or fewer people in the business who apply pesticides and does not hold himself out as a professional applicator. Advertise weed and feed service and you have forfeited both exemptions. A professional applicator whose financial responsibility lapses has the license automatically suspended until the Department verifies compliance. Operating as a professional or private applicator or dealer without a license forfeits one hundred dollars per day of operation to the state as a civil penalty, and the Department can seek an injunction.

The Department's rules carry the numbers. IDAPA 02.03.03 sets the professional applicator license fee at three hundred dollars, the commercial apprentice applicator license at one hundred twenty dollars, the private applicator license at twenty five dollars, a chemigation license at fifty dollars, a pesticide dealer license at two hundred fifty dollars per five year licensing period, and the examination fee at ten dollars per examination category. The Department's licensing guide confirms the license cycles: professional, dealer, private and chemigation licenses are valid five years, professional licenses expire December 31 of the fifth year, private licenses expire March 31 of the fifth year, and a commercial apprentice license expires two years from issue and cannot be renewed. Adding extra license categories carries no charge beyond testing. Proof of financial responsibility can be liability insurance with an Idaho licensed insurer on a Department approved form, a Department approved bond, a cash certificate of deposit in escrow, an annuity, or an irrevocable letter of credit from a national or Idaho state chartered bank. Minimum coverage is bodily injury of fifty thousand dollars per person and one hundred thousand dollars per occurrence, property damage of fifty thousand dollars per occurrence, and a maximum deductible of five thousand dollars. Recertification is credit based. A professional applicator must accumulate forty recertification credits during the five year period by attending Department accredited seminars, with one credit issued for each fifty minutes of instruction. Private applicators need fifteen credits. Miss the credits and you retake the exams before you can renew.

Sprinkler work is where landscaping brushes against the plumbing chapter, and the line is drawn by pipe location and system type. Idaho Code 54-2601 adopts the Uniform Plumbing Code published by the International Association of Plumbing and Mechanical Officials, plus any amendments the Idaho Plumbing Board makes by rule, and names the combined result the Idaho State Plumbing Code. Idaho Code 54-2603 defines plumbing to include the design, construction, installation, improvement, extension and alteration of all piping, fixtures, appliances and appurtenances connected with a plumbing system. Idaho Code 54-2602 then carves out a path that excavating contractors rely on: nothing in the chapter requires a sewer contractor, sewage disposal contractor, or any excavating or utility contractor who generally installs, alters or repairs sewers, sewage disposal systems and water distribution or drainage lines outside the foundation walls of a building to hold a certificate of competency or to employ only certified journeyman plumbers. Work that ties into the potable system inside the building envelope does not get that pass. Idaho Code 54-2611 sets six competency classes, three in plumbing and three in specialty plumbing, each with contractor, journeyman and apprentice tiers. Permits are separate from competency. Idaho Code 54-2620 makes it unlawful to install, improve, extend or alter any plumbing system or its service lines without a permit from the Division of Occupational and Professional Licenses, except inside counties or cities that enforce an equivalent code by ordinance. Idaho Code 54-2621 waives permits only for clearing stoppages and repairing leaks that involve no functional rearrangement of pipes, valves or fixtures.

Tie an irrigation system into a public water supply and a second rulebook applies. The Idaho Rules for Public Drinking Water Systems, IDAPA 58.01.08, require every community water system purveyor to run a cross connection control program using premises isolation, internal isolation, fixture protection or some combination. The program must include an inspection program to locate cross connections and determine required protection, and for new connections the system owner must verify suitable protection was installed before water service begins. That verification step is why your sprinkler tie in gets inspected before the meter is turned on. The rules require installation and operation of adequate backflow prevention assemblies selected from the Uniform Plumbing Code, the AWWA recommended practice for backflow prevention and cross connection control, the USC Foundation manual, or other sources the Department of Environmental Quality accepts, and the selected model must appear on the USC Foundation list of approved assemblies and comply with local ordinances. Testing is annual. All installed backflow prevention assemblies must be inspected and tested every year by a tester licensed by a licensing authority recognized by the Department, using USC Foundation test procedures. Non community systems carry the same annual testing duty with an Idaho licensed tester. Assemblies that fail a test or are found defective must be repaired, replaced or isolated within ten business days, and if that cannot be done the water service to the failed assembly must be discontinued. Double check valve assemblies, reduced pressure principle assemblies, spill resistant vacuum breakers and pressure vacuum breakers all count as testable assemblies under the rule.

Bidding a school district courtyard, a city park planting or a highway district streetscape pulls you into Idaho Code Title 54 Chapter 19. Idaho Code 54-1902 makes it unlawful to engage in the business or act in the capacity of a public works contractor in Idaho without first holding a license issued by the administrator of the Division of Occupational and Professional Licenses. Idaho Code 54-1901 defines public works contractor to include any person who undertakes, offers to undertake or submits a proposal for construction, repair or reconstruction of any public work for the state, a county, city, school district, sewer district, fire district or any other taxing subdivision. The same section treats the terms builder, subcontractor and specialty contractor as synonymous, so sitework and planting subcontractors are covered. Specialty construction is defined as work requiring special skill and specially skilled trades or crafts. The threshold sits in the exemption list. Idaho Code 54-1903 exempts any construction, alteration, improvement or repair involving a single project with an estimated cost of less than one hundred thousand dollars, and exempts a subcontractor working under the direct supervision of a licensed public works contractor holding a Class Unlimited, AAA, AA or A license when the subcontracted work is worth less than one hundred thousand dollars. The license is classed by capacity, and the board's initial fees effective January 1, 2025 are eight hundred eighty dollars for Unlimited, seven hundred twenty for AAA, five hundred sixty for AA, four hundred for A, two hundred forty for B, two hundred for CC, one hundred sixty for C, and three hundred twenty dollars for construction manager. A public works contractor may not subcontract more than eighty percent of a contract.

Idaho writes the display duty into the statute, and it is broader than a sign on the truck. Idaho Code 54-5214 requires a contractor registered under the chapter to prominently display the contractor registration number for public view in the place of business, on advertising, on contracts, on permits, on company or business letterheads, and on purchase orders and subcontracts, within sixty days of the registration being issued. Read that list as written. Your website, your estimate template, your proposal cover page and the subcontracts you issue to your own trades all belong in it. The same section issues a certificate of registration plus a wallet sized card showing the registrant's name and registration number, makes certificates non assignable and non transferable, and requires notice to the board within thirty days of any change of ownership or address. Renewal applications are due on or before thirty days prior to expiration. Plant material advertising carries its own rule. Idaho Code 22-2311 bars advertising any plant material covered by the nursery chapter in any media without disclosing the company name or license number, and Idaho Code 22-2305 requires the nursery license number to be prominently displayed in each outlet. Title wording is policed separately. Idaho Code 54-3003 prohibits using landscape architect or landscape architecture, or any description tending to convey that impression, unless licensed, and Idaho Code 54-5205 bars any exempt person from holding himself out as a registered contractor. Call yourself a licensed landscape contractor and a registered Idaho contractor if those are true. Do not reach for architect.

Idaho gives buyers two public records and one piece of paper to ask for. The Division of Occupational and Professional Licenses runs a public search through its Online Services portal, which covers contractor registrations, landscape architect licenses, public works contractor licenses and plumbing certificates, and the Division directs people to that same public search for information on formal disciplinary actions against registered contractors. The Idaho State Department of Agriculture maintains separate public lookups for nursery licenses and for pesticide applicator licenses, reachable from its Nursery, Florist and Landscaping page and its applicator licensing page. A customer who wants a physical check can ask for the wallet sized card that Idaho Code 54-5214 requires the board to issue with the registrant's name and registration number on it. There is a third verification route built into the permit process. Idaho Code 54-5209 requires a county, city or district permit issuer to request an Idaho contractor registration number before issuing any construction permit, and to enter that number conspicuously on the face of the permit. The permit must then be posted at the construction site so the statement stays visible. A permit that reads "no contractor registration provided" is telling the homeowner the person who pulled it claimed an exemption. Smart contractors use all of this. Put your registration number on the estimate, hand over the card, and point at the state search rather than waiting to be asked. The paperwork that proves you are current is a selling point for the customer who already got burned once.

Working unregistered in Idaho costs more than a fine. Idaho Code 54-5217 makes acting in the capacity of a contractor without a current registration a misdemeanor punishable by a fine of up to one thousand dollars, up to six months in county jail, or both. The second subsection hurts more: no person engaged in the business or acting in the capacity of a contractor, unless exempt, may bring or maintain any action in any Idaho court to collect compensation for work requiring registration without alleging and proving they were registered at all times during the performance. An unregistered patio job is a gift. Idaho Code 54-5208 is titled denial of lien rights. On the nursery side, Idaho Code 22-2324 makes any violation of the nursery chapter a misdemeanor and allows the Department to assess a civil penalty of not more than five hundred dollars per offense plus reasonable attorney fees, with a thirty day window to appeal an assessment to district court. Violating the landscape architect chapter, including offering to practice or representing yourself as entitled to practice without a license, is a misdemeanor under Idaho Code 54-3005, and each act is treated as a separate offense. The city layer is thinner than in most states because Idaho Code 54-5213 forbids municipalities and counties from running their own contractor registration programs. What remains local is permitting. Boise's Planning and Development Services Building Division issues building permits and runs inspections inside the city, and Idaho Code 54-2601 lets cities and counties adopt and enforce the Idaho State Plumbing Code and amend it only to a level at least equivalent to the Uniform Plumbing Code.

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.
Yes, and usually two. The Idaho State Department of Agriculture licenses anyone who installs or furnishes landscape plants, at one hundred dollars for the principal place of business. The Idaho Contractors Board separately registers contractors whose construction work on a project totals two thousand dollars or more.
Idaho Code 54-5205 exempts work on one project considered casual, minor or inconsequential where the aggregate contract price for labor, materials and everything else is under two thousand dollars. It does not apply when the work is part of a larger project or when a job is split to evade the chapter.
Read Idaho Code 22-2302 first. It defines a landscape contractor as someone landscaping property for which they furnish the plants, trees or shrubs. The Department's own page is broader and says anyone engaging in the installation of landscape plants must be licensed, so confirm your situation with ISDA before skipping it.
Yes. Idaho Code 54-3003 exempts landscape contractors, landscape nurserymen and gardeners, including their right to plan and supervise. What you cannot do is use the words landscape architect or landscape architecture, or any description tending to convey that impression, unless you hold the license.
Idaho Code 54-5210 requires a certificate from an insurer authorized in Idaho showing general liability coverage, including products and completed operations, of not less than three hundred thousand dollars single limit. It also requires proof of worker's compensation coverage or a written statement of why coverage is not required.
The registration statute does not impose a surety bond on contractors generally. Idaho Code 54-5210 lists worker's compensation and general liability insurance instead. A separate two thousand dollar surety bond applies under Idaho Code 54-2602 to anyone making water treatment installations or repairs.
If you advertise the service, yes. Idaho Code 22-3404 exempts hand powered application of non restricted products to lawns, trees and shrubs only when the business employs two or fewer applicators and does not hold itself out as a professional applicator. Advertising ends that exemption.
IDAPA 02.03.03 sets the professional applicator license fee at three hundred dollars and the examination fee at ten dollars per category. The Department's licensing guide states the license runs five years and expires December 31 of the fifth year, with forty recertification credits required to renew.
IDAPA 58.01.08 requires all installed backflow prevention assemblies to be inspected and tested annually by a tester licensed by a licensing authority the Department of Environmental Quality recognizes, using USC Foundation procedures. Failed assemblies must be repaired, replaced or isolated within ten business days or service is cut.
No. Idaho Code 54-5213 bars every incorporated municipality, county, alternative form of local government and other political subdivision from implementing its own program for registering or licensing construction contractors. Cities still issue building and plumbing permits and run inspections, and Boise does that through its Building Division.
Idaho Code 54-5217 makes it a misdemeanor carrying up to a one thousand dollar fine, up to six months in jail, or both. Worse for cash flow, an unregistered contractor cannot bring or maintain any Idaho court action to collect payment for work that required registration.
Idaho Code 54-5214 requires it displayed for public view in your place of business and on advertising, contracts, permits, company letterheads, purchase orders and subcontracts, within sixty days of issue. Idaho Code 22-2311 separately requires your company name or nursery license number on plant material advertising.
