How Seattle Handles Short-Term Rentals: A Practical Guide

Seattle maintains 201 local ordinances across all categories, and 6 of those deal specifically with short-term rentals. Here is a breakdown of what the city actually requires, what is prohibited, and where Seattle falls on the strict-to-permissive spectrum compared to other cities.

Host Presence Rule

Seattle SMC 6.600 STR Ordinance (2017) requires every host to hold a STR Operator License plus a regulatory license. Operators are limited to their primary residence plus one additional dwelling unit citywide.

Key details: Code: SMC 6.600. Effective: January 2019. Unit cap: 2 dwelling units. STR tax: $14/night. Sales+lodging tax: ~15.6%.

Operating without STR license: $1,000 first violation, $2,000+ subsequent. Exceeding two-unit limit: $500 per night. Tax non-payment: collection plus penalties under SMC 5.45.

Compared to other cities, Seattle takes a harder line on host presence rule. The enforcement and penalty structure reflects that.

Occupancy Limits

Seattle Municipal Code Chapter 6.600 limits a short-term rental operator to a maximum of two dwelling units citywide: the operator's primary residence (where they live more than six months a year) and one secondary unit within Seattle, with grandfathered exceptions for some Downtown Urban Core legacy listings. SMC 6.600 does not set a specific guest-per-bedroom cap, but the underlying dwelling is still subject to occupancy and life-safety standards in the Building, Fire, and Housing codes. STRs are prohibited in RVs, tents, garages, boats, floating residences, waterfront residences, live-work units, and commercial caretaker quarters.

Key details: Maximum two units: Maximum two units per operator (primary residence + 1 secondary). Primary residence: operator: Primary residence: operator must live there more than 6 months a year. ADU/DADU/in-law unit can: ADU/DADU/in-law unit can serve as the primary unit. Rooms without separate: Rooms without separate kitchen/bath do not count toward 2-unit cap. STRs prohibited in: STRs prohibited in RVs, tents, garages, boats, live-work, floating homes.

Operating without a required STR operator license carries a $500 penalty for a first violation and $1,000 for second and subsequent violations under SMC 6.600. Operating without a Seattle business license tax certificate is a separate citation of approximately $513. SDCI can pursue land use and housing-code violations under SMC 23.42.060 and Title 22 with fines reported in published guidance at $150 to $500 per day, plus inspection charges. Failure to display the operator license number on listings, exceeding the two-unit cap, or operating in a prohibited structure type can result in license suspension or revocation by FAS, in addition to per-day code-compliance penalties.

Parking Rules

Seattle Municipal Code Chapter 6.600 does not impose a dedicated off-street parking requirement on short-term rentals, and SMC 23.42.060 (Land Use Code) does not require additional parking specifically for STR use beyond what applies to the underlying dwelling. STR guests parking on city streets must follow standard SDOT rules: posted time limits, street-cleaning postings, the 72-hour vehicle storage limit, and Restricted Parking Zone (RPZ) rules. In RPZ areas, only one guest hangtag is issued per household; short-term day permits are available in most zones (up to 5 per day, 50 per year per address).

Key details: Smc: SMC 6.600 imposes no STR-specific off-street parking requirement. Smc: SMC 23.42.060 does not add STR parking beyond underlying use. Street Parking Limited: Street parking limited to 72 consecutive hours (SMC Title 11). Rpz Areas: RPZ areas: one guest hangtag per household, 4 vehicle decals max. Short: Short-term RPZ day permits: 5 per day, 50 per year per address.

SDOT parking citations vary by violation type and are generally consistent with citywide rates: time-limit, meter, and RPZ overstays typically run from roughly $47 to $65, while street-cleaning, fire-hydrant, and 72-hour overtime violations can result in higher fines and a tow under SMC Title 11. Blocking a driveway or curb cut is subject to citation and tow. Chapter 6.600 imposes no parking-specific STR penalty, but repeated guest parking complaints contributing to a pattern of nuisance can be considered by FAS in license enforcement, with $500 first-violation and $1,000 subsequent-violation penalties available under the STR ordinance.

The rules around parking rules in Seattle lean permissive, but that does not mean anything goes.

Noise Rules

Seattle short-term rental guests must comply with Seattle Municipal Code Chapter 25.08 (Noise Control), which sets a 55 dBA daytime limit and a 45 dBA nighttime limit at the property line of a residential receiving zone. Quiet hours run 10:00 p.m. to 7:00 a.m. on weekdays and 10:00 p.m. to 9:00 a.m. on weekends and legal holidays. Operators are responsible under SMC 6.600 for guest conduct, and repeated verified noise complaints can support enforcement against the STR operator's regulatory license. Active disturbances are reported to the Seattle Police non-emergency line at 206-625-5011.

Key details: Local Contact: Quiet hours: 10 p.m. to 7 a.m. weekdays; 10 p.m. to 9 a.m. weekends and holidays. Requirement: Daytime limit: 55 dBA at residential property line (SMC 25.08). Occupancy: Nighttime limit: 45 dBA at residential property line. Requirement: First noise infraction: $250 civil penalty. Requirement: Operator responsible under SMC 6.600 for guest conduct.

A first-time noise infraction under Chapter 25.08 carries a civil penalty starting at $250. A second violation within a 24-hour period may be charged as a misdemeanor punishable by up to 180 days in jail and/or a $500 fine, with escalating penalties for repeat offenses. Separately under SMC 6.600, FAS may impose $500 for a first STR violation and $1,000 for subsequent violations, and may suspend or revoke the STR operator license after a documented pattern of nuisance complaints. SDCI may also pursue housing-code enforcement against the property if applicable.

Taxes & Fees

Seattle STR hosts must collect Washington State lodging taxes under RCW 67.28. Seattle imposes a Business License Tax (based on gross receipts). The $75/year per-unit STR regulatory license fee applies separately.

Key details: State Lodging Tax: RCW 67.28 (collected by platforms). City B&O Tax: Seattle B&O Tax on gross receipts. STR License Fee: $75/unit/year. Business License: Also required — filelocal-wa.gov.

Failure to collect/remit taxes: state and local tax penalties. B&O tax non-filing: Washington DOR enforcement.

Permit Requirements

Seattle requires STR operators to hold a City Business License Tax Certificate and a separate STR Operator's Regulatory License ($75/unit/year) under SMC Chapter 6.600. Operators are limited to 2 units; one must be their primary residence if operating 2. Non-primary-residence STRs must also register with RRIO.

Key details: Code: SMC Chapter 6.600. Operator License: $75/unit/year. Unit Cap: Max 2 units per operator. Primary Residence: Required if operating 2 units. RRIO: Required for non-primary-residence STRs.

Operating without required licenses violates SMC 6.600. Penalties per city code enforcement.

Compared to other cities, Seattle takes a harder line on permit requirements. The enforcement and penalty structure reflects that.

The Bottom Line

Seattle is tougher than many cities when it comes to short-term rentals. Out of the 6 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Seattle, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

Keep in mind that Seattle can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
