Renton, WA Fire Regulations: Fire Pit Rules (2026)

Renton Regional Fire Authority and the city enforce International Fire Code Section 307 as adopted through Renton Municipal Code 4-5-070 for recreational outdoor fires. Portable outdoor fireplaces, chimineas, and permanent in-ground fire pits burning only seasoned cordwood or manufacturer-approved fuel are permitted on private property, but must sit at least 25 feet from any structure, property line, fence, or combustible vegetation. Fire size is limited to 3 feet in diameter and 2 feet in height per IFC 307.4.2. Fires must be constantly attended by a competent adult with a garden hose, bucket of water, or approved fire extinguisher within reach, and fully extinguished before leaving. Listed portable outdoor fireplaces and listed gas appliances may sit as close as 15 feet per manufacturer labeling. Trash, leaves, yard debris, construction waste, pressure-treated lumber, and painted wood cannot be burned. Puget Sound Clean Air Agency (PSCAA) issues Stage 1 and Stage 2 burn bans that override local allowances during poor air quality or stagnant conditions in King County. During Stage 2 bans, even certified wood stoves are restricted. May Creek, Cedar River, and steep slope areas require extra caution due to salmon habitat and wildland-urban interface risks.
