Overview

Seattle's outdoor fire feature rules are shaped by two primary factors: the Puget Sound Clean Air Agency (PSCAA) wood-burning curtailment program and Seattle's dense residential zoning, where small lot sizes make meeting the 25-foot recreational fire setback challenging.

Seattle's curtailment season runs October through March and can produce 20–30+ restricted days per season during stagnant air events — temperature inversions are common in the Puget Sound basin during winter. Like other western cities, gas fire features are not restricted and are increasingly the practical choice for Seattle homeowners.

Building Permits in Seattle

Seattle Department of Construction and Inspections (SDCI) issues building permits for permanent fire features. Seattle is known for a relatively accessible permitting process for simple residential work. The Seattle Services Portal (seattle.gov/sdci) allows online permit applications and status tracking.

Portable fire pits, fire bowls, and propane units don't require a building permit. Permanent masonry features and gas-connected units do. Seattle's Environmentally Critical Areas (ECA) regulations may affect permitting if your property is in a designated shoreline, steep slope, or riparian buffer — check SDCI before assuming standard rules apply.

PSCAA Wood-Burning Curtailment

The Puget Sound Clean Air Agency covers King, Pierce, Snohomish, and Kitsap counties. Curtailment days ban wood burning in residential fireplaces, fire pits, and outdoor wood-burning appliances unless wood burning is the sole source of heat in the home.

Check curtailment status at pscleanair.gov or sign up for alerts. Declarations are typically made the afternoon before they take effect. Gas fire features are not restricted.

Seattle Permit Process Notes

Seattle's residential neighborhoods have significant lot size variation. In dense neighborhoods like Capitol Hill, Queen Anne, or Ballard, meeting a 25-foot setback from structures and combustible fences with an open fire pit may be geometrically impossible. This is why many Seattle homeowners use enclosed portable units (which qualify for the 15-foot setback under IFC 307.4.3, if Seattle has adopted the 2018 IFC — verify with SDCI) or opt for gas features that are permitted under standard setback rules.
