Business Licensing & Operations in Seattle, WA

If you live in Seattle or are thinking about moving there, business licensing & operations are one of those things you probably won't think about until they affect you directly. Seattle has 8 specific rules on the books covering different aspects of business licensing & operations, and some of them might surprise you.

Massage Establishments

Massage businesses in Seattle must hold both a state Department of Health practitioner license under RCW 18.108 and a city massage business license under SMC 6.290, with background checks, anti-trafficking signage, and inspections targeting illicit massage operations.

Key details: State law: RCW 18.108. City code: SMC 6.290. Education hours: 640 minimum. Background check: Fingerprint required. Sleeping on site: Prohibited.

Operating an unlicensed massage business, employing unlicensed practitioners, missing trafficking notices, allowing residential use of treatment rooms, or sexual contact triggers license revocation, criminal charges, fines up to $5,000, and possible state license discipline.

This is one of the stricter rules in Seattle's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Towing Companies

Tow operators in Seattle need a WA State Patrol registered tow truck operator (RTTO) certificate under RCW 46.55 plus a Seattle business license, and must follow city impound-rate caps, signage rules for private-property impounds, and SDOT rotational towing contracts.

Key details: State statute: RCW 46.55. City code: SMC 11.30. Sign posting: 24 hours minimum. Rate authority: WSP cap schedule. Retrieval hours: 24/7 access.

Towing from a lot without compliant signage, exceeding state-published rate caps, refusing 24/7 vehicle retrieval, missing the SDOT rotation contract, or using uncertified drivers exposes operators to civil penalties up to $1,000 per tow, license suspension, and treble-damages claims.

This is not one of those rules that cities tend to ignore. Seattle actively enforces its towing companies requirements.

Tattoo & Body Modification

Operating a tattoo shop in Seattle without a City license is unlawful under SMC 6.102.020, and the application goes to the Director of Finance and Administrative Services with review by the Chief of Police and Director of Public Health before it can issue. The annual fee is $530, licenses expire February 28, and no one under 18 may hold one.

Key details: Governing chapter: SMC Chapter 6.102 Tattooing. License required: Tattoo shop license from FAS Director. Annual license fee: $530.00 (SMC 6.102.030). License expiration: Every February 28. Minors: Written parental consent required, kept 2 years.

SMC 6.102.100 makes any violation of Chapter 6.102, operating unlicensed, tattooing a minor without consent, or failing the shop's sanitation standards, punishable by a fine of up to $300, up to 90 days in City Jail, or both. FAS can also revoke or suspend the shop license under SMC 6.102.090, with the Public Health Director's recommendation driving revocation for health-code violations found during inspection.

Auto Repair on Residential Property

Seattle lets residents run automotive retail sales and services as a home occupation, but SMC 23.42.050(F) bars any "substantial increase in on-street parking congestion or...traffic within the immediate vicinity," and like every home occupation the business is capped to three associated vehicles on site, each under 10,000 pounds gross vehicle weight.

Key details: Max vehicles at site: 3, each under 10,000 lbs GVW. Auto-specific standard: no substantial parking/traffic increase. Drive-in service bays: not permitted (SMC 23.42.050.I). Governing section: SMC 23.42.050(F)-(G). Late compliance penalty: up to $500/day after day 10.

Running a car-repair business that pushes past these limits is a Title 23 land-use violation, not just a licensing issue: SDCI can issue a notice of violation under SMC 23.90.006 and pursue a civil penalty of up to $150 per day for the first ten days of noncompliance and up to $500 per day after that under SMC 23.90.018.A until the vehicle count, parking impact or noise is brought back into line.

Adult Entertainment

Operating an adult entertainment premises in Seattle without a license from the Director of Finance and Administrative Services is unlawful under SMC 6.270.040, and every entertainer and manager needs a separate license too. Premises licenses cost $905 a year, entertainers $170, managers $216, and no one under 18 may enter or work such a venue.

Key details: Governing chapter: SMC Chapter 6.270 Adult Entertainment. Premises license fee: $905.00 per year. Entertainer license fee: $170.00 per year. Manager license fee: $216.00 per year. Prohibited hours: 2:30 a.m. to 10:00 a.m..

SMC 6.270.100(F) and 6.270.110(D) make it unlawful to violate the chapter's conduct, posting, or recordkeeping standards. FAS may suspend or revoke a premises license under SMC 6.270.150 for cause, and a new license application is barred for one year after a final revocation or suspension order under SMC 6.270.090. Operating outside licensed hours or admitting a minor under SMC 6.270.130-.140 is independently unlawful.

This is not one of those rules that cities tend to ignore. Seattle actively enforces its adult entertainment requirements.

Pawnbrokers

Pawnbrokers in Seattle operate under WA RCW 19.60, capping monthly interest at three percent plus a small fee, requiring 90-day loan terms, daily SPD reporting, and a 30-day police hold on pawned goods before forfeiture and sale.

Key details: Statute: RCW 19.60. Interest cap: 3 percent monthly. Loan term: 90 days minimum. Police hold: 30 days post-forfeit. Reporting: Daily to SPD.

Charging excess interest, accepting goods without ID, skipping daily reports, selling forfeited items before the 30-day hold, or operating without a license triggers misdemeanor charges, civil penalties, license suspension, and refund liability to borrowers.

This is one of the stricter rules in Seattle's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Secondhand Dealers

Secondhand dealers in Seattle must register under SMC 6.288, comply with WA RCW 19.60 reporting, hold purchases for 30 days, photograph and electronically transmit transaction details to the Seattle Police Department through LeadsOnline, and verify seller identification.

Key details: State law: RCW 19.60. City code: SMC 6.288. Holding period: 30 days. Reporting system: LeadsOnline daily. Charity exemption: Most donations exempt.

Failing to verify ID, skipping daily electronic reporting, altering or selling items before the 30-day hold, or refusing inspection exposes dealers to misdemeanor charges, license revocation, and forfeiture of any property linked to theft.

Tobacco Retail License

Selling any tobacco product in Seattle, pipe tobacco, cigars, cigarettes, chewing tobacco, snuff, or cigarillos, without a City tobacco product retailer's license is unlawful under SMC 6.240.020. The license runs July 1 to June 30 annually, costs $135 per location, vehicle, or operation under SMC 6.204.120, and mobile vendors must follow a fixed, approved route.

Key details: Governing chapter: SMC Chapter 6.240 Retail Sale of Tobacco. License required: Tobacco product retailer's license from FAS. Annual fee: $135 per location, vehicle, or operation. License year: July 1 to June 30. Route-change fee: $25 to reissue after relocation.

Selling tobacco without the SMC 6.240.020 license, running an unlicensed mobile route, or breaking the sealed-package rule under SMC 6.240.080 is a civil infraction under SMC 6.240.200. Selling to a minor under SMC 6.240.100 is a gross misdemeanor carrying absolute liability, with every sale during a visit, unless part of one multi-item purchase, counted as a separate violation.
