California · Plumbing licensing · official-source guide
California licenses plumbing at state level through the Contractors State License Board, which issues the C-36 Plumbing Contractor classification. No city license replaces it. You need four years of journeyman level experience in the last ten years, passing scores on the Law and Business exam and the C-36 trade exam, a $25,000 contractor bond, and workers compensation coverage or a filed exemption.

The Contractors State License Board issues every plumbing contractor license in California. It is a state board, not a city or county office. CSLB headquarters sits at 9821 Business Park Drive, Sacramento, CA 95827, and its mailing address is P.O. Box 26000, Sacramento, CA 95826. There is no separate Los Angeles plumbing contractor license, no San Diego version and no Fresno version. One CSLB license number works in all 58 counties. Cities still issue building permits and still require business tax certificates, and those are separate from licensure. What a city cannot do is hand you the right to contract for plumbing work. Only CSLB does that. The board classifies contractors rather than licensing individual tradespeople by title. A plumber working for wages under a licensed contractor does not hold a CSLB license of their own. The company, or the qualifying individual who stands behind the company, holds it. This is the first thing that trips up plumbers moving in from states that license a master plumber personally and separately from the business. In California the license attaches to the business entity and to the person who qualified it. If that qualifier leaves, the license has a problem. CSLB charges $230 to replace a qualifier on an existing license. Plan for that before a key person walks. The classification you want for plumbing work is C-36. CSLB also publishes a public license check that anyone can use, which means your licence status, classifications and complaint history are a matter of public record from the day the number issues. Treat the qualifier decision as a hiring decision rather than a filing decision. Adding new personnel to a license costs $125 and adding a limited partner costs $125, so the structure you choose at the start carries a recurring administrative cost as the company grows.
CSLB defines C-36 under California Code of Regulations, Title 16, Division 8, Article 3, with authority from Business and Professions Code sections 7008 and 7059. The board's definition reads that a plumbing contractor provides a means for a supply of safe water, ample in volume and of suitable temperature for the purpose intended, and the proper disposal of fluid waste from the premises in all structures and fixed works. The scope is wider than most people assume. It reaches waste removal and on-site disposal systems. It reaches piping, storage tanks and venting for gases and liquids, including vacuum, compressed air, and medical, dental, commercial and industrial gases. It reaches gas appliances, flues and gas connections for all systems, including suspended space heating units, but it excludes forced warm air units. It reaches water and gas piping running from the utility meter to the structure. It reaches equipment installed to heat water or fluids to a suitable temperature, and CSLB names solar equipment in that item. It reaches maintenance and replacement of everything above plus safety devices, and the board lists earthquake valves, backflow preventers, water conditioning equipment and regulating valves by name. Read the exclusion carefully. Forced warm air units sit outside C-36 and belong to C-20. If you sell a furnace changeout on a C-36 alone, you are working outside your classification, which is its own violation. One more consequence follows from the classification system. CSLB tells contractors they cannot advertise for construction work outside the areas for which they are licensed. So the boundary of C-36 is not only a boundary on what you may install. It is a boundary on what you may put in an ad, on a truck, or on a service page of your website. A C-36 that markets whole-home HVAC replacement has created an advertising violation before anyone picks up a wrench.
Any business that contracts for plumbing work in California needs a license. CSLB's minor work exemption is the only general escape and it is small. AB 2622 raised that exemption from $500 to $1,000 starting January 1, 2025. Two conditions ride with it. The work cannot require a permit, and the unlicensed person cannot employ anyone for the project. Miss either condition and the exemption is gone no matter how small the invoice. The threshold counts labor and materials combined, not labor alone. A water heater swap with a permit is not exempt at any price. A B General Building license does not substitute for C-36 on a plumbing-only job. Under the board's classification rules a general building contractor takes a project involving at least two unrelated trades, so a general who wants to sell straight plumbing work needs the C-36 as well. Adding a classification to a license you already hold costs $230. Adding one at the time of original application costs $150. The exemption also shapes advertising. An unlicensed person may advertise for work up to $1,000 only if the advertisement states that the person is not licensed. That disclosure is the price of the exemption, and CSLB treats a missing disclosure as an advertising violation in its own right. There is a second threshold worth holding alongside the $1,000 exemption, because the two get confused. A written home improvement contract is required for residential projects of $500 or more in combined labor and material costs. That $500 figure is a contract-form rule, not a licensing exemption. The $1,000 figure is the licensing exemption. A job at $700 needs a written contract and needs a license. Keeping those two numbers straight is the difference between a clean file and a citation.

CSLB requires at least four full years of experience at a journeyman level, or as a foreman, supervisor or contractor, in the classification applied for. The experience must fall within the ten years immediately before the application is filed. The board's own application form states the same rule and adds that the four years must be at no less than a journeyman level. Applicants must be 18 or older. The experience has to be verifiable. Someone with direct knowledge of the work signs for it, and CSLB can and does contact that person. A plumber who cannot cover all four years personally can instead be represented by a qualifying individual who has the experience and stands behind the license. Education shortens the clock but does not erase it. CSLB may grant up to three years of credit toward the four-year requirement for completed training in an accredited school or an apprenticeship program. Three years is the ceiling, which means at least one year of real field experience remains in every case. Apprenticeship hours and trade school both feed this credit. Keep pay records, permits pulled under your name, and contact information for supervisors who can verify each stretch of work. Reconstructing four years of history from memory after the fact is the slowest way through this step. CSLB verifies rather than assumes. The board states that experience must be verifiable through individuals with knowledge of the work history, so the certifier you name may be contacted. Build the documentation while the work is happening. Keep permits pulled under your name, W-2s or 1099s covering each stretch, and current contact details for the supervisors who can sign. The four-year window sits inside a ten-year lookback, so time spent outside the trade quietly shrinks the pool of usable years.

Every C-36 applicant sits two separate written exams. The first is the Law and Business exam, which every classification takes. The second is the C-36 trade exam. CSLB allows three and a half hours for each examination. Exams run through the board's testing vendor at 20 test centers inside California and 21 outside it. The Law and Business exam is offered in several states. The trade exam is available only in California and Oregon, so plan travel accordingly if you live out of state. Results come as a printed report at the end of the sitting. A passing report tells you that you passed and does not show your overall score. A failing report does show the overall score and the number of items answered correctly, which at least tells you how far off you were. Fail and you can retake after 21 calendar days, as long as you are still inside your 18-month void date, and you pay the re-examination fee to the testing vendor to reschedule. Cancel at least two days before your appointment or you forfeit the fee. The C-36 trade exam content outline weights five areas. Planning and estimating is 22 percent. Underground and rough systems is 22 percent. Finish plumbing installations is 20 percent. Service, repair and remodel is 19 percent. Safety is 17 percent. One more item sits between passing the exams and holding the license. CSLB's issuance checklist requires a completed asbestos open-book examination before the license is issued. It is not the trade exam and it is not scheduled at a test center, but the license does not issue without it. Applicants who pass both written exams and then stall for weeks are usually stalled on this, on the bond, or on the workers compensation filing.
California runs a criminal history check on everyone attached to the license. CSLB requires that all applicants for license, and each officer, partner, owner and responsible managing employee, be fingerprinted. Home improvement salesperson applicants are fingerprinted too. The process runs through Live Scan. You complete the applicant information section of the form, take three copies to a Live Scan station, and the station submits the prints to the California Department of Justice and the FBI. You pay the Live Scan operator three separate amounts: a $32 DOJ fingerprint processing fee, a $17 FBI fingerprint processing fee, and the operator's rolling fee, which varies by location. The prints are compared against DOJ and FBI records to determine whether the applicant has a criminal history. A conviction does not automatically end the application. CSLB reviews case by case. The board may deny a license for conviction of a crime that is substantially related to the qualifications, functions or duties of the business or profession, subject to the time limits and crime types set in law. Disclose honestly. A conviction CSLB finds on the print results that you did not report is a separate problem from the conviction itself. Build the Live Scan step into your timeline early, because the license does not issue while prints are outstanding. Plan the sequence rather than reacting to it. Prints go to DOJ and FBI and come back on their own schedule, and every officer, partner, owner and responsible managing employee has to clear. A four-person ownership group is four Live Scan appointments, not one. If you intend to register home improvement salespeople later, budget the same step for each of them, because HIS applicants are fingerprinted on the same basis.

The original application fee is $450 and it is nonrefundable. That fee covers one classification. Once you pass both exams and clear the background review, an initial license fee is due before the license issues. CSLB charges $200 for a sole owner and $350 for a non-sole owner. Adding a second classification on a new license costs $150. Adding a classification to an existing license costs $230. Replacing the qualifier on an existing license also costs $230. Adding new personnel costs $125, and adding a limited partner costs $125. If you let a license go inactive and want it back, reactivation costs $450 for a sole owner and $700 for a non-sole owner. A joint venture application is $800. Home improvement salesperson registration is $200. The asbestos certification and the hazardous substance removal certification are $125 each. Housekeeping costs money too. A business name change is $100, duplicate certificates are $25, a certified license history is $67, and status letters are $8 each. None of these figures include the Live Scan fees, the bond premium, or your workers compensation policy, which are paid to other parties. Budget the application fee and the initial license fee as two separate events months apart, because that is how CSLB collects them. The small line items add up during a build-out. Document copies run $0.10 per page, and certified copies run $2 plus $0.10 per page. A certified license history is $67 and status letters are $8 each, which matters when a general contractor or a property manager asks for documentation before adding you to a vendor list. None of it is large on its own. All of it lands in the same quarter you are also paying the bond premium and the first workers compensation deposit.
California requires a $25,000 contractor's bond under Business and Professions Code section 7071.6. That amount took effect January 1, 2023. CSLB describes the bond as filed for the benefit of consumers who may be damaged as a result of defective construction or license violations. The board's issuance checklist accepts a contractor bond or a cashier's check of $25,000. A bond is not insurance for you. If a claim pays out, the surety comes back to you for the money. A second bond applies when the license is qualified by someone other than an owner. The bond of qualifying individual is also $25,000, under Business and Professions Code section 7071.9, effective the same date. It is required for responsible managing employees and for certain responsible managing officers. A company qualified by an RME therefore carries two $25,000 bonds, not one. A third bond exists and you want to stay away from it. The disciplinary bond under Business and Professions Code section 7071.8 is required when a license has been revoked. Its minimum is $25,000 and its maximum is ten times the contractor's bond amount, and it is filed in addition to any other bond required. CSLB does not accept a bond that lapses. A cancelled bond suspends the license, and work done while suspended is unlicensed work. The bond has a second use most contractors never exploit. Under California's home improvement rules the legal down payment is capped at $1,000 or 10 percent of the contract price, whichever is less, unless the contractor has a blanket performance and payment bond on file with CSLB. For a plumbing company selling repipes and sewer replacements, that exception is the difference between financing the material yourself and collecting a real deposit. It is worth pricing with your surety.
California law requires employers, including those in construction, to carry workers compensation insurance even with only one employee. CSLB names classifications that must always carry coverage regardless of employees: active C-8 Concrete, C-20 Warm-Air Heating, Ventilating and Air-Conditioning, C-22 Asbestos Abatement, C-39 Roofing, and C-61/D-49 Tree Service. C-36 is not on that always-required list, so a C-36 with no employees may file an exemption certificate with the board instead of a policy. The exemption has hard limits. You cannot file it if you employ anyone in a manner subject to California workers compensation laws, or if your license is qualified by a responsible managing employee, or if you hold one of the specified classifications. The exemption stops being valid the moment you hire. CSLB states that upon hiring employees the exemption form on file is no longer valid and you must obtain and submit proof of coverage within 90 days. The penalty is direct. Failure to maintain workers compensation coverage results in the license being suspended, and any work performed while the license is suspended is considered unlicensed. That is the quiet way a growing plumbing company loses its license: it hires its first helper, forgets the certificate, and every job after that is unlicensed work with no right to collect. Keep the exemption certificate and the payroll decision in the same conversation. The moment a helper goes on payroll, the filing on record with CSLB is stale, and CSLB gives 90 days to replace it with proof of coverage. A suspension for lapsed coverage is not merely a fine. CSLB states that work performed while the license is suspended is considered unlicensed, which pulls in the consumer remedies that come with unlicensed work.

This is where California gets stricter than most states, and where contractors lose money for nothing. Business and Professions Code section 7030.5 requires licensed contractors to include the license number in all construction contracts, in subcontracts and calls for bid, and in all forms of advertising. CSLB reads advertising broadly. Its guidance lists cards, contracts, signs, billboards, vehicle lettering, brochures, newspapers, magazines, radio and television, electronic transmissions, directories, promotional materials and yard signs. Your website counts. Your online ads count. Your truck counts. The board defines advertising in California Code of Regulations section 861 and points to sections 7027, 7029.5 and 7030.5 as the governing law. Two rules catch people who think they are already compliant. First, licensees must list the business name exactly as it appears in CSLB records for any advertisement, bid or contract. A shortened trading name on a landing page is a violation even when the license number is right there. Second, licensees are responsible for any omission even when the license number was inadvertently left off by an outside agency hired to produce the ad. Hiring a marketing company does not move the liability. Check every asset you did not build yourself: the directory listing someone else typed, the vehicle wrap the shop laid out, the ad the platform reformatted. The board's advertising definition is broad by design. CSLB describes advertising as including the issuance of any card, sign or device to any person, and it reaches contracts, signs, billboards, vehicle lettering, brochures, newspapers, magazines, airwaves, electronic transmissions and directories. Electronic transmissions is the phrase that covers the parts of your marketing that did not exist when the section was written: your Google Business Profile, your paid search ads, your email quotes.

California has a general vehicle advertising rule and then a tougher one that applies specifically to C-36. Under the general rule, a licensed contractor displays business name and contractor license number on each commercially registered vehicle, in a clearly visible location, in print type of at least 72-point font, or three quarters of an inch in height and width. CSLB cites Business and Professions Code section 7029.6 for that. C-36 Plumbing does not follow that rule. Under Business and Professions Code section 7029.5, plumbing contractors, along with C-45 Sign and C-57 Well Drilling, must display three things on each side of the vehicle: the business name, the permanent business address, and the contractor license number. The lettering must be at least one and a half inches high. Read that again, because two of those items are extra. Other trades do not have to put a street address on the truck. C-36 does. And the letters are twice the height the general rule requires, on both sides rather than simply in a clearly visible location. A plumbing company that wrapped its fleet to the general 72-point standard is out of compliance and will not know until a complaint arrives. The cost of getting it wrong is not theoretical. CSLB states that the civil penalty for licensees who violate contractor advertising laws can range from $100 to $5,000, and its advertising guidance puts a first offense at $100 to $1,000 under California Code of Regulations section 884. A fleet wrap is a capital purchase you make once every several years. Confirm the C-36 format before the vinyl is cut, because correcting a wrapped fleet costs far more than the citation.

The license lets you advertise plumbing work as defined in the C-36 classification and nothing further. CSLB states that contractors cannot advertise for construction work outside the areas for which they are licensed without holding the appropriate classifications. A C-36 that advertises furnace replacement is advertising outside its classification, because forced warm air units sit outside C-36. The same goes for advertising general remodeling on a plumbing-only license. There is one prohibition that surprises nearly everyone. CSLB's advertising guidance tells contractors not to advertise that they are bonded, on the reasoning that it could lead a consumer to believe bonding offers a higher level of protection than it does. The phrase licensed and bonded is common in plumbing advertising and CSLB tells California contractors to leave the bonded half out. False advertising carries its own exposure. CSLB states that it is a misdemeanor to use false, misleading or deceptive advertising to induce clients to enter into improvement contracts. An unlicensed person may advertise only for work up to $1,000 and only with a statement in the advertisement that the person is not licensed. If you are licensed, say so with the number. If you are not, the disclosure is mandatory. There is no quiet middle position that California treats as acceptable. The practical read for a plumbing company is simple. Advertise the classification you hold, name it accurately, and put the number next to the claim. Drop the word bonded. Keep the business name identical to CSLB records across the website, the directories, the truck and the estimate template. Every one of those surfaces is an advertisement under California law, and each one is a separate opportunity to be out of compliance on a detail nobody in the office is watching.

Most residential plumbing work in California is home improvement work, which brings a second layer of rules. A written contract is required for home improvement projects of $500 or more in combined labor and material costs. The contract must include a complete listing of contractor contact information and the contractor's license number, plus homeowner contact information. The legal down payment is $1,000 or 10 percent of the contract price, whichever is less, unless the contractor has a blanket performance and payment bond on file with CSLB. That limit is absolute and it is the single most commonly broken rule in residential trades. The homeowner has a three-day right to cancel, exercised by written notice by midnight of the third business day after receiving a signed and dated copy. Payments should track completed phases of work, and CSLB tells consumers not to pay ahead of completion. If you employ anyone to sell, a second registration applies. A person employed by a licensed contractor to solicit, sell, negotiate or execute contracts for home improvements must register as a Home Improvement Salesperson. Officers of licensed corporations, managers and members of LLCs, qualifying persons, and service repairpersons whose work is limited to requested repairs are not required to register. HIS registration costs $200. Once registered, a salesperson may work for more than one contractor. Registration is not a one-time errand either. Home improvement salesperson registration renews, at $200 timely and $300 delinquent, and HIS applicants are fingerprinted like licensees. If you run a residential plumbing operation with comfort advisors or sales technicians who write and close contracts, that is an ongoing compliance line rather than a one-off. The exemption for service repairpersons is narrow: it covers work limited to the repair the customer requested, not the upsell conversation that follows it.
Active licenses expire every two years. Inactive licenses expire every four years. An acceptable renewal application must reach CSLB headquarters before the expiration date to avoid any unlicensed time, and unlicensed time is not a paperwork problem, it is a period during which your contracts may be unenforceable. Timely active renewal costs $450 for a sole owner and $700 for a non-sole owner. Miss the date and delinquent renewal costs $675 for a sole owner and $1,050 for a non-sole owner. Inactive timely renewal is $300 for a sole owner and $500 for a non-sole owner, rising to $450 and $750 when delinquent. There is a 90-day recovery window. A completed renewal application received with the appropriate fees within 90 days of the expiration date allows retroactive reinstatement. After that the gap stands. An expired license may be renewed any time within five years after expiration. Past five years you reapply from scratch with an Application for Original Contractor's License, which means the $450 application fee again and, potentially, the exams again. CSLB's renewal instructions do not impose a continuing education requirement for the C-36 classification. What keeps a license alive is the bond, the workers compensation status and the renewal filing, so track those three dates rather than a class schedule. Two dates and one status keep a California plumbing license alive. The renewal date, the bond expiration date, and the workers compensation status. Any one of them failing produces the same outcome, which is a period of unlicensed time you cannot bill against. Put all three on the same calendar, with the bond renewal ahead of the license renewal, and review them at the same meeting each quarter rather than trusting a mailed reminder to reach the right person.

California has reciprocity agreements, and for plumbing the list is shorter than the general list suggests. CSLB names Arizona, Louisiana, Mississippi, Nevada and North Carolina among its reciprocity partners. When you narrow the reciprocal classifications table to C-36 Plumbing, only Arizona classifications map across. CSLB lists Arizona C-37 Plumbing Including Solar, C-37R Plumbing, K-37 Plumbing, K-77 Plumbing Including Solar, L-37 Plumbing and L-77 Plumbing Including Solar as mapping to California C-36. The other reciprocity states do not have plumbing classifications on that table. Understand what reciprocity buys. CSLB may waive the trade portion of the exam but retains the right to require it. The applicant still takes the business law portion. So an Arizona plumbing contractor moving to California may skip the C-36 trade exam and still sits the Law and Business exam, still gets fingerprinted, still posts the $25,000 bond, still files workers compensation proof or an exemption, and still pays the $450 application fee and the initial license fee. Nothing about reciprocity shortens the bond, the insurance or the advertising rules. Experience earned out of state still counts toward the four-year requirement on its own terms, so a plumber from a state with no reciprocity agreement is not blocked. They simply take both exams. There is one further waiver route on the same page. CSLB notes that candidates with five or more years holding a qualifying license in the originating state who have passed the NASCLA Commercial Building examination may qualify for an exam waiver. That is aimed at commercial general contractors rather than at C-36 specifically, so a plumbing contractor should confirm what it reaches before planning around it. Either way, the business law exam remains.
CSLB publishes the consequences plainly. A first offense of contracting without a license is a misdemeanor carrying up to six months in jail and a $5,000 fine, plus an administrative fine of $200 to $15,000. A second offense carries a mandatory 90-day jail sentence and a fine of 20 percent of the contract price or $5,000. Felony prosecution applies when someone illegally uses another person's contractor license, tries to mislead consumers into believing they are licensed, or contracts for work in a state or federal disaster area without an active license, and a felony conviction may bring state prison. The civil side hurts too. Consumers are not legally required to pay a person who is not state-licensed, and an unlicensed contractor cannot sue for non-payment. Advertising violations carry a civil penalty between $100 and $1,000 for a first offense under California Code of Regulations section 884. Customers verify all of this in about fifteen seconds. CSLB runs a public license check at cslb.ca.gov that searches by license number, business name, personnel name, HIS registration number or salesperson name. It shows license status, classifications, bond and workers compensation status, and complaint disclosure. Assume every serious residential prospect looks you up before they call, because the board tells them to. CSLB's reach over unlicensed operators lasts longer than most people assume. The board states it has jurisdiction over unlicensed contractors for up to four years from the date of the illegal act under Business and Professions Code section 7028(d). The same public tools that let a customer check you also let them find someone else. CSLB's site offers a companion tool to find licensed contractors by city or ZIP code, which is one more reason to keep your record clean and your listing accurate.

These are common details other guides publish about California, but we could not verify them from the agency source. Confirm them directly before relying on them.
By the state. The Contractors State License Board issues the C-36 Plumbing Contractor license and it is valid statewide. Cities issue building permits and business tax certificates, but no city issues the plumbing contractor license itself.
Four full years at a journeyman level, or as a foreman, supervisor or contractor, in the classification applied for, earned within the ten years immediately before the application is filed. CSLB may grant up to three years of credit for accredited school or apprenticeship training.
Two. The Law and Business exam and the C-36 trade exam. CSLB allows three and a half hours for each. The trade exam is offered only in California and Oregon.
Five weighted areas. Planning and estimating at 22 percent, underground and rough systems at 22 percent, finish plumbing installations at 20 percent, service, repair and remodel at 19 percent, and safety at 17 percent.
The nonrefundable application fee is $450 for one classification. The initial license fee due before issuance is $200 for a sole owner or $350 for a non-sole owner. Live Scan fees, the bond premium and insurance are paid separately.
$25,000, under Business and Professions Code section 7071.6, effective January 1, 2023. A license qualified by a responsible managing employee also needs a $25,000 bond of qualifying individual under section 7071.9.
C-36 is not on CSLB's list of classifications that must always carry coverage, so a C-36 with no employees may file an exemption certificate. The exemption becomes invalid the moment you hire, and you then have 90 days to file proof of coverage.
In all construction contracts, in subcontracts and calls for bid, and in all forms of advertising. CSLB's list includes business cards, signs, billboards, vehicle lettering, brochures, print, broadcast, electronic transmissions, directories and yard signs.
C-36 follows Business and Professions Code section 7029.5, not the general rule. Each side of the vehicle must show the business name, the permanent business address and the license number, in letters at least one and a half inches high.
CSLB's advertising guidance tells contractors not to advertise that they are bonded, because it could lead a consumer to believe bonding offers a higher level of protection than it does. Advertise the license and the license number instead.
Active licenses expire every two years and inactive licenses every four. Timely active renewal is $450 for a sole owner and $700 for a non-sole owner. CSLB's renewal instructions do not impose a continuing education requirement for C-36.
