How to apply
To obtain a Washington State Residential Contractor License, apply through the Department of Labor & Industries online portal at https://lni.wa.gov/contractor-registration. You must submit Form Contractor-100 with proof of workers' compensation insurance coverage and a copy of your business registration (UBI number from the Washington Secretary of State). The application requires documentation of experience in bathroom remodeling or related construction work.
You must pass the Washington Contractor License exam, which tests knowledge of the Residential Building Code, contractor law (RCW 18.27), and general construction practices. The exam costs approximately $100 and can be scheduled through Pearson VUE testing centers in Spokane. You need four years of documented construction experience in the trade or a combination of apprenticeship and experience totaling four years. Alternatively, if you have a journeyperson plumber or electrician license, you may qualify with less general construction experience.
Once approved, you receive your license number valid for three years. You must display your license number on all advertising, contracts, and business vehicles per RCW 18.27.040. Submit proof of current workers' compensation insurance and liability insurance (minimum $100,000 general liability recommended). The application processing typically takes 2-3 weeks after exam passage.
Federal Requirements
Bathroom remodelers must obtain a federal Employer Identification Number (EIN) from the IRS (26 U.S.C. § 6109) if they plan to hire employees. Compliance with the Americans with Disabilities Act (ADA) applies when bathroom remodeling involves accessibility modifications or occurs in commercial spaces subject to Title III regulations. The EPA's Lead-Based Paint Rule (40 CFR Part 745) applies if working on residential properties built before 1978, requiring EPA certification and lead-safe work practices. OSHA standards (29 U.S.C. § 651 et seq.) govern workplace safety, dust control, and hazard communication for bathroom renovation work.
Federal tax obligations include self-employment tax if operating as a sole proprietor or partnership. Bathroom remodelers hiring employees must comply with the Fair Labor Standards Act (29 U.S.C. § 201 et seq.) regarding wages and working hours. If offering credit or financing to customers, compliance with the Truth in Lending Act (15 U.S.C. § 1601) and Regulation Z applies. No specific FDA, FCC, or ATT licenses are required for bathroom remodeling, but general federal contractor liability and workers' compensation standards apply to all federal projects.
Local & County Requirements
Bathroom remodeling projects in Spokane require permits from the appropriate jurisdiction based on location. If your project is within Spokane City limits, obtain a building permit from the Spokane City Department of Building Services. For projects in unincorporated Spokane County, contact the Spokane County Building and Planning Department.
Required local permits typically include: Building Permit (required for all bathroom remodeling work to verify code compliance), Electrical Permit (if modifying electrical systems, outlets, or ventilation fans), Plumbing Permit (required for all plumbing work including fixture installation and supply/drain modifications), and Mechanical/HVAC Permit (if installing or modifying ventilation systems). Many bathroom remodels require both electrical and plumbing permits simultaneously.
Zoning compliance verification is mandatory—staff will review whether bathroom additions or structural changes comply with residential zoning. Inspection requirements include rough-in inspections (before drywall) and final inspections after completion. Spokane City requires inspections at rough-in, insulation, and final stages. Permit fees vary by project scope but typically range from $150-$400 depending on estimated project value. Processing time for permit applications is 5-10 business days in Spokane City and 7-14 days in unincorporated county areas. Some bathroom remodels in commercial properties or involving structural changes may require additional fire marshal review.
Total Cost Breakdown
The first-year cost for launching a bathroom remodeling business in Spokane includes several mandatory expenses. The Washington State Residential Contractor License costs $300-$450 for the initial application and issuance. The contractor licensing exam through Pearson VUE costs approximately $100.
Local permits for a typical bathroom remodeling project range from $200-$500 depending on project scope and jurisdiction (Spokane City vs. County). This includes the building permit, electrical permit, and plumbing permit fees. Estimated costs are based on project valuation; larger bathroom remodels will incur higher permit fees.
Workers' compensation insurance is mandatory if you employ workers and costs approximately $400-$800 annually based on payroll size and claim history (new businesses pay roughly $15-$25 per $100 of payroll). General liability insurance is strongly recommended at $300-$600 annually for bathroom remodeling work. Total estimated first-year startup costs range from $1,300-$2,450 including licensing, permits, and insurance. Ongoing annual renewal costs (year two and beyond) are approximately $700-$1,200 for license renewal, general liability, and workers' compensation insurance. Project-specific permit costs will vary by job size and complexity.
Licence Renewal
Washington State Residential Contractor Licenses expire every three years, with renewal deadlines based on your issue date. You must renew before the expiration date listed on your license to maintain legal status. Renewal is accomplished online through the Department of Labor & Industries contractor portal at https://lni.wa.gov.
Renewal fees are approximately $300-$400 and must be submitted with proof of current workers' compensation insurance coverage. Washington does not require continuing education for contractor license renewal, but you must demonstrate compliance with all state contractor regulations during the three-year period. If you fail to renew by your expiration date, your license becomes inactive and you cannot legally contract work until reinstatement is completed.
Reactivation after expiration requires submitting a late renewal application with fees and updated insurance documentation. Late fees may apply if you submit renewal more than 30 days after expiration. Renewal can be completed entirely online, and you receive a renewal certificate via email upon approval. It is recommended to submit renewal applications 30-45 days before expiration to allow processing time and avoid work interruptions.
Penalties for Operating Without a Licence
Operating as a bathroom remodeler in Washington without a valid Residential Contractor License constitutes a violation of RCW 18.27.080 and RCW 18.27.140. Civil penalties for unlicensed contracting range from $3,000 to $5,000 per violation, with each day of continued unlicensed operation potentially counted as a separate violation. Cumulative violations over a 12-month period can result in penalties exceeding $10,000.
Criminal penalties apply in cases of willful or repeated violations. A violation of contractor licensing laws is prosecuted as a crime in the second degree under RCW 9A.20.021, punishable by up to three months imprisonment and/or a fine up to $1,000. The Washington Department of Labor & Industries maintains a cease-and-desist authority and can order immediate work stoppage if an unlicensed contractor is discovered operating.
Violations are discovered through customer complaints, Department of Labor & Industries investigations, permit office audits, and insurance claim reviews. Homeowners have legal recourse to recover payment for work performed by unlicensed contractors. Operating without a license also voids workers' compensation insurance, exposing you to personal liability for employee injuries. Customers can sue for recovery of all contract amounts paid to unlicensed contractors. Additionally, homeowner claims made through Washington's Home Improvement Guaranty Act (RCW 18.27.180) apply only to licensed contractors, creating significant financial and legal exposure for unlicensed operators.

Frequently Asked Questions
Do I need a Washington contractor license if my bathroom remodeling projects are under $1,000?
Washington State law (RCW 18.27.010) requires a Residential Contractor License for virtually all bathroom remodeling work regardless of dollar amount if the work involves structural changes, plumbing, electrical, or mechanical systems. The $1,000 threshold mentioned in contractor law refers to alterations that do not substantially change the structure. Since bathroom remodeling typically involves plumbing, electrical, and sometimes structural work, you need a license even for smaller projects. The safest approach is to obtain your license before advertising or accepting any bathroom remodeling contracts. Operating without a license on even a single small project exposes you to significant penalties and liability.
How long does it take to get a bathroom remodeler license in Spokane, from application to approval?
The total timeline typically spans 4-8 weeks. First, you must schedule and pass the Washington Contractor License exam through Pearson VUE, which may take 1-2 weeks to schedule depending on availability (testing centers in Spokane have regular openings). The exam itself takes 3-4 hours. After passing, you submit your application to the Department of Labor & Industries with supporting documentation, which takes 2-3 weeks for processing. If your application is incomplete or requires clarification, processing extends an additional 1-2 weeks. To accelerate the process, gather all required documents before scheduling your exam: UBI number from Washington Secretary of State, workers' compensation insurance certificate, and proof of four years experience or equivalent qualification.
What specific permits does Spokane City require for bathroom remodeling beyond the state contractor license?
Spokane City requires a Building Permit for all bathroom remodeling work, obtained through the City Department of Building Services at https://my.spokanecity.org. Nearly all bathroom remodels also require both an Electrical Permit (for outlet installation, ventilation fan wiring, or any electrical modifications) and a Plumbing Permit (for fixture changes, supply line modifications, or drain work). If you are installing new ventilation ducting or HVAC components, a Mechanical Permit is required. Each permit requires a separate application and inspection. The Building Permit is the primary permit; electrical and plumbing permits are subordinate permits issued through the same process. Processing time is 5-10 business days for initial permit issuance, and inspections must be scheduled for rough-in and final stages. Total permit costs typically range from $250-$450 for a standard bathroom remodel.
What happens if I start bathroom remodeling work without obtaining my Washington license first?
Operating without a Washington Residential Contractor License is illegal and carries serious consequences. You face civil penalties of $3,000-$5,000 per violation under RCW 18.27.080, and each day of continued unlicensed operation may constitute a separate violation. The Department of Labor & Industries can issue a cease-and-desist order immediately halting your work if discovered. Criminal charges for willful violation are prosecuted as a crime in the second degree, punishable by up to three months jail time and fines up to $1,000. Customers can sue to recover all payment for work performed by an unlicensed contractor. Your workers' compensation insurance will not cover employee injuries, leaving you personally liable. Additionally, any defective work cannot be covered under Washington's Home Improvement Guaranty Act, creating liability exposure. Obtain your license before accepting the first job.
Can I transfer my bathroom remodeler license from another state to Washington, or do I need to get licensed from scratch?
Washington does not offer reciprocal licensing for bathroom remodelers or general contractors from other states. You must obtain a Washington Residential Contractor License through the standard process regardless of licenses held elsewhere. However, if you hold a valid journeyperson plumber or electrician license from another state, you may be able to satisfy the four-year experience requirement more quickly—contact the Department of Labor & Industries to determine if your credential qualifies. Out-of-state experience counts toward the four-year requirement, but you must document it through work history verification, tax returns, or employer letters. You must still pass the Washington-specific contractor license exam, which covers Washington residential building code (WAC 51-51C), contractor law (RCW 18.27), and general contracting practices. The exam cannot be waived based on out-of-state experience or credentials.
What insurance coverage is required for bathroom remodelers in Washington, and what are typical costs?
Washington mandates workers' compensation insurance if you employ any workers (including part-time or family members in some cases). Self-employed solo operators without employees are exempt from workers' compensation requirements but must carry it if hiring even one employee. General liability insurance is not mandated by state law but is required by Spokane building permit offices for permit approval and is essential protection against property damage and bodily injury claims. Standard workers' compensation insurance for bathroom remodeling businesses costs $400-$800 annually based on payroll size and loss history (new businesses typically pay $15-$25 per $100 of payroll). General liability insurance with minimum $100,000 coverage costs $300-$600 annually depending on business size and claims history. Many homeowners require proof of both coverages before hiring. Bonding requirements vary—Spokane City does not mandate bonding, but some clients request performance bonds costing $200-$400 for larger projects.
