Half of Seattle's homes were built in 1976 or earlier, and 21% were built in 2010 or later. With 21% of homes built since 2010, newer layouts matter here: the USFA notes that construction trends often put washers and dryers in upstairs bedrooms, hallways, bathrooms, kitchens and closets, which may require a longer duct to reach an outside wall.
In Washington, clothes dryers were the equipment involved in 3.9% of residential structure fires where the equipment was identified, in fire department records for 2020 to 2024, below the national 4.6%. Failure to clean is the leading factor nationally, in 31.2% of dryer fires with a known cause. Details and state-by-state figures: dryer fire statistics.
Seattle dryer vent code rules
The Seattle Residential Code covers single-family houses, duplexes and townhouses with no more than three stories and with separate entrances, and the Seattle Department of Construction and Inspections (SDCI) says Seattle has adopted the 2021 International Residential Code with amendments specific to the city. SDCI's timeline page says the 2021 editions of the Seattle construction codes went into effect on November 15, 2024.
The clothes dryer exhaust section (M1502) in Seattle's published 2021 residential code has the same wording as the 2021 International Residential Code. The Seattle Mechanical Code sends detached one- and two-family dwellings and townhouse units of not more than three stories with a separate means of egress to the residential code, so its own dryer exhaust wording in section 504.4 applies to other buildings: a backdraft damper located where the duct terminates, termination allowed at exterior wall louvers with openings spaced not less than 1/2 inch in any direction, and, for domestic dryer exhaust ducts, termination allowed at a common exhaust location where each duct has an independent back-draft damper.
Under the 2021 International Residential Code, a dryer exhaust duct can run at most 35 feet, minus an allowance for each elbow (M1502.4.6.1), or the length the dryer maker's installation instructions allow (M1502.4.6.2); the hose behind the dryer must be one listed piece of 8 feet or less (M1502.4.3); and the duct must end outside with a backdraft damper and no screen (M1502.3), and domestic booster fans are not allowed (M1502.4.5).

Permits for dryer vent work in Seattle
SDCI answers permit questions at (206) 684-8600. For buildings under the Seattle Mechanical Code (not houses, duplexes or townhouses of up to three stories, which follow the residential code), section 113.1 requires a permit from the code official prior to each installation, alteration, repair, replacement or remodel of any equipment or mechanical system regulated by the code, and section 113.2.1 exempts minor work or the replacement of any component part of a mechanical system that does not alter its original approval and complies with other applicable requirements of the code. SDCI's permit page says that, unless you are in an environmentally critical area, painting or cleaning a building usually does not require a permit, but you need a permit for work that reduces egress, light, ventilation or fire resistance, no matter how small the project. None of these texts mentions dryer vents.
Local resources in Seattle
The Seattle Fire Department's free smoke/CO alarm program provides battery-powered combination smoke/CO alarms, installed by Seattle firefighters, in the homes of Seattle homeowners who own and live in their home and identify as two of the following: senior (age 65 and up), living on a low income, or having any type of disability (the department's page words the criteria more than one way, so check with it); it does not provide alarms for rental properties or for home sale purposes. For renters, the department's page says the landlord is required to provide a working smoke and CO alarm and tenants are responsible for maintaining the alarms, and that a tenant whose rental has no smoke alarm should inform the landlord of this obligation.
Under Seattle's Rental Registration and Inspection Ordinance (RRIO), all rental property owners in Seattle must register their properties with the City, and inspectors make sure registered properties comply with minimum housing and safety standards at least once every 5 to 10 years. For work under a mechanical permit, SDCI's mechanical inspections page says inspections can be requested through the Seattle Services Portal or the 24-hour automated line at (206) 684-8900 with the permit number, and that calls before 7 AM usually get a same-day inspection.
