Who registers renovation and remodeling contractors in Washington?
In Washington, remodelers must register as construction contractors with the Department of Labor and Industries (L&I) under chapter 18.27 RCW; the state uses registration with bond and insurance rather than a general contractor exam.
Registration is either as a general contractor, who may perform or manage work across trades, or as a specialty contractor, limited to one of the 63 specialties L&I regulates. A kitchen and bath company that also coordinates drywall, flooring and finish carpentry typically registers as a general contractor; a firm doing only cabinets or only flooring may register in that specialty. Before registering, the business must obtain a Unified Business Identifier through the Department of Revenue, and incorporated businesses also form through the Secretary of State. Specialty contractors may work only within their registered specialty, so check that the category matches the full scope of the job.
Registration is not the end of the licensing picture. Electrical, plumbing, boiler, elevator, manufactured home installation and asbestos work carry separate education, exam and licensing requirements, and lead-based paint work requires certification through the Department of Commerce. A registered general contractor running a bathroom remodel therefore still needs a licensed electrical contractor and certified plumbers for those parts of the job unless its own staff hold those credentials. The application fee for registration and renewal is $150.20, and the registration must be kept current with an active bond and insurance on file at all times.
What bond and insurance does a Washington remodeling contractor need?
A Washington general contractor must post a $30,000 bond and a specialty contractor a $15,000 bond, plus liability insurance, before L&I issues or renews a registration.
The bond amounts in RCW 18.27.040 rose on July 1, 2024 under the 2023 legislation known as 2SHB 1534, up from $12,000 for general contractors and $6,000 for specialty contractors. Contractors registered before that date kept their old bond until their next renewal, so every active registration should now show the higher amount. A contractor may substitute an assigned savings account held at a Washington branch for the surety bond. L&I also blocks a contractor that switches from general to specialty from reducing its bond for two years. The bond number and surety appear on the public L&I record.
For insurance, L&I accepts general liability coverage of $200,000 public liability and $50,000 property damage, or a $250,000 combined single limit, with L&I named as certificate holder. Homeowners should understand what the bond does and does not do. It is a fund for claims against the contractor, shared among all claimants, and $30,000 can be exhausted quickly on a large remodel or when several customers sue at once. That limitation is the reason Washington created the Homeowner Recovery Program, which can pay part of a bond judgment that remains unpaid after the bond is used up.

How do I check a renovation contractor in Washington before I sign?
7 checks, in order, using the Washington registers and rules described on this page:
- Look up the business in the L&I Verify a Contractor tool and confirm an active registration, the general or specialty category, the $30,000 or $15,000 bond, and current insurance.
- Review the L&I record for lawsuits against the bond and past infractions, since multiple bond claims can exhaust the bond before your claim is paid.
- Before any work starts on a job of $1,000 or more, get and sign the RCW 18.27.114 disclosure statement showing the registration number and bond amount.
- Ask whether the bid includes Washington retail sales tax on the gross contract price at the rate for your job site, and compare bids on the same basis.
- Confirm who will obtain the permit from your city or county building department and how the 2021 Washington State Energy Code, Residential, applies to your scope.
- For a home built before 1978, ask for the firm Department of Commerce lead RRP certificate and for the asbestos good faith inspection report required by RCW 49.26.013.
- Collect lien release documents from suppliers and subcontractors before final payment, as the disclosure statement entitles you to request.
When can someone remodel in Washington without registering with Labor and Industries?
Washington exempts casual or minor jobs under $500 total and owners working on their own property, but anyone advertising as a contractor or splitting jobs to stay under the limit must register.
Under RCW 18.27.090, the minor-work exemption covers work where the aggregate contract price for labor, materials and all other items is less than $500, so long as the work is not part of a larger operation, is not broken into smaller contracts to evade the law, and the person does not advertise as a contractor. Owners may perform work on their own property or personal residence, and may do maintenance, repair and alteration with their own employees. An owner who has held property for less than twelve months and contracts to improve it for sale or lease does not get the exemption for hiring a registered contractor, which affects flippers.
The consequences of skipping registration fall mostly on the contractor. RCW 18.27.080 bars an unregistered contractor from suing in Washington courts for compensation or breach of contract on work that requires registration, unless it can prove it was registered. Substantial compliance is narrow: the contractor must have had its information on file and kept bond and insurance in force at all times. For homeowners, the bigger risk is that an unregistered operator has no bond, and work by unregistered contractors is not eligible for the Homeowner Recovery Program. L&I also issues infractions to unregistered contractors, and those penalties help fund that program.
Which building and energy codes apply to a Washington remodel?
Washington remodels follow the statewide 2021 codes, including the 2021 Washington State Energy Code, Residential, in effect since March 15, 2024; the 2024 codes take effect May 3, 2027.
The State Building Code Council adopts the International Residential Code and the Washington State Energy Code with state amendments, and local building departments enforce them. The 2021 cycle was delayed twice before taking effect March 15, 2024. For the 2024 cycle, the Council has announced that the 2024 codes take effect May 3, 2027, with a goal of finalizing the energy codes by November 20, 2026. Remodelers who will be permitting additions or major alterations in spring 2027 should watch which edition will apply on the date of complete permit application.
The Washington State Energy Code, Residential, set out in chapter 51-11R WAC, generally reaches additions and alterations to existing homes, not just new houses. That affects insulation levels, window performance, mechanical ventilation and duct sealing on remodels that open walls or add conditioned space. Some cities, including Seattle, adopt local amendments to the energy code, so the permit office in the city where the house sits is the final word on what an inspector will look for. Ask the remodeler early how the energy code affects your scope, because insulation and ventilation upgrades can change both the budget and the wall assemblies.
What are the lien deadlines for remodeling jobs in Washington?
Washington lien claimants must record a claim of lien within 90 days after they stop furnishing labor or materials, serve the owner within 14 days, and sue to foreclose within eight months.
Under RCW 60.04.091, the notice of claim of lien is recorded in the county where the property is located within 90 days after the claimant last furnished labor, professional services, materials or equipment. A copy must reach the owner within 14 days after recording, by certified or registered mail or personal service; missing that step forfeits the right to recover attorney fees and costs from the owner. Under RCW 60.04.141, the lien lapses eight calendar months after recording unless a foreclosure action is filed in superior court in that time and the owner is served within 90 days of filing.
Remodelers working directly for an owner do not have to send the RCW 60.04.031 notice to owner, but suppliers and lower-tier claimants generally do, and a notice protects only materials and services supplied within 60 days before it is given. On existing owner-occupied single-family homes, liens of those who did not contract directly with the owner can be satisfied only from amounts not yet paid to the prime contractor when the notice arrives. Most important for remodelers, RCW 18.27.114 bars a lien claim on a residential contract unless the contractor proves it gave the required disclosure statement.
How do climate and older housing affect remodeling in Washington?
Washington remodelers contend with persistent moisture west of the Cascades, colder dry winters to the east, significant seismic risk, and older housing that can contain asbestos and lead paint.
In the wet Puget Sound region, renovation scopes often grow once walls are opened and rot, failed flashing or poorly ventilated bathrooms are found, so experienced remodelers build contingency into bids and pay close attention to weather-resistive barriers, window flashing and exhaust ventilation. Eastern Washington projects face larger temperature swings and snow loads. Statewide, seismic considerations affect structural changes, such as removing bearing walls or adding second stories, which require engineered design and permits from the local building department. Older homes may also benefit from foundation bolting and cripple wall bracing when a remodel already opens the crawlspace.
Older housing brings regulated materials. RCW 49.26.013 requires the owner or owner agent to arrange a good faith asbestos inspection by accredited inspectors before a project that could disturb or release asbestos, and to give the report to contractors before they bid, unless the owner is reasonably certain asbestos will not be disturbed or another statutory exception applies. Local clean air agencies such as Puget Sound Clean Air Agency add their own notification rules. Washington also runs its own lead Renovation, Repair and Painting program through the Department of Commerce for homes and child-occupied facilities built before 1978; firms apply with copies of renovator certificates and a $25 fee.
What must a Washington remodeler give a homeowner before work starts?
Before starting a residential job of $1,000 or more in Washington, the contractor must give the customer the RCW 18.27.114 disclosure statement and obtain a signature acknowledging receipt.
The disclosure statement applies to repair, alteration or construction of four or fewer residential units or accessory structures where the bid or contract totals $1,000 or more. It must substantially follow the statutory form and show the contractor registration number, bond amount and registration expiration date; warn that the bond may not cover all claims; explain that the customer may withhold contractually defined retainage; warn that unpaid suppliers, workers and subcontractors can lien the property; and explain that the customer may request lien release documents. The contractor keeps a signed copy for three years and must notify the customer if its registration lapses, is suspended or is revoked before the contract ends.
Pricing in Washington also works differently than in many states. Under Department of Revenue guidance, a prime contractor doing construction or remodeling for a landowner collects retail sales tax from the owner on the gross contract price, sourced to the job site at the combined state and local rate, and reports the receipts under the retailing business and occupation tax. Remodeling bids should state sales tax separately, and homeowners comparing bids should check whether each one includes it. Because the rate depends on the job site location, two identical bids can carry different tax totals in neighboring cities.
How does the Washington Homeowner Recovery Program work?
Since July 1, 2026, Washington owner-occupants holding an unpaid superior court judgment on a contractor bond claim can apply to L&I for up to $25,000 per contractor per parcel.
The program comes from 2SHB 1534, Chapter 213, Laws of 2023, and is implemented by rules in chapter 296-200A WAC that L&I adopted April 21, 2026. A claimant must own an owner-occupied residential property, meaning a single-family dwelling or a building of four or fewer units, not including condominiums, and must have owned and occupied it when the work was done. The claimant must first sue on the contractor bond under RCW 18.27.040, obtain a final superior court judgment, and show that the judgment has not been fully paid. Claims must be filed within 90 days after the civil action concludes.
Under WAC 296-200A-9120, L&I pays the unpaid judgment amount up to $25,000 per contractor per parcel. The account is funded by fines and penalties collected under the contractor registration law, especially infractions against unregistered contractors, rather than by a fee on registered firms. Payments depend on available funds and may be waitlisted. Only work by a lawfully registered contractor qualifies, which makes checking the L&I registration before signing the single most valuable step a Washington homeowner can take. Program rules also let L&I seek reimbursement from the contractor after paying a claim.

Frequently asked questions
Does Washington require remodelers to pass a licensing exam?
No general exam is required for L&I contractor registration. Registration rests on a UBI number, a bond, liability insurance and the application fee. Electricians, plumbers and some other trades need separate certification and exams, so remodelers either hold those credentials or subcontract that work to licensed firms.
Why did Washington contractor bonds go up?
The 2023 law known as 2SHB 1534 raised bonds to $30,000 for general contractors and $15,000 for specialty contractors effective July 1, 2024, from $12,000 and $6,000. The higher amounts apply at each renewal on or after that date, giving consumers more recovery against a contractor bond.
What happens if my remodeler never gave me the disclosure statement?
Failing to provide the RCW 18.27.114 disclosure on a covered residential job is an infraction, and the contractor cannot bring or maintain a lien claim on that contract unless it proves it delivered the statement. You can report the omission to L&I, which enforces the contractor registration law.
Can a condominium owner use the Washington Homeowner Recovery Program?
No. The program rules define residential property as a single-family dwelling or a multifamily dwelling of four or fewer units and expressly exclude condominiums. The owner must also have occupied the property when the work was done and hold an unpaid superior court judgment on a bond claim.
Do Washington remodelers charge sales tax on labor?
Yes. A prime contractor working for a landowner collects retail sales tax on the gross contract price, which includes labor and materials, at the combined state and local rate for the job site. The tax should be stated separately on bills.
When do the 2024 Washington building codes take effect?
The State Building Code Council has announced that the 2024 codes take effect May 3, 2027. Until then the 2021 codes, including the 2021 Washington State Energy Code, Residential, which took effect March 15, 2024, govern permits for remodels and additions.
How long does a Washington subcontractor have to lien my house?
A claim of lien must be recorded within 90 days after the claimant last furnished labor or materials, and a copy must be sent to the owner within 14 days of recording. The lien expires after eight months unless a foreclosure suit is filed.
