Renton, WA Fire Regulations: Backyard Fires (2026)

Renton allows recreational backyard fires under International Fire Code Section 307 as adopted through Renton Municipal Code 4-5-070, but with strict size and conduct rules. A recreational fire means an outdoor fire burning clean materials other than rubbish, with a total fuel area no larger than 3 feet in diameter and 2 feet in height, for cooking, warmth, or ceremony. The fire must be at least 25 feet from any structure, fence, deck, or combustible material. An adult must attend at all times with a water hose, bucket, or extinguisher ready. Burning of yard waste, leaves, construction debris, plastics, treated wood, or garbage is always prohibited under PSCAA Regulation 1. Portable outdoor fireplaces and chimineas are treated as recreational fires. Natural gas or propane fire features listed by UL or CSA can be placed closer (typically 15 feet from structures) per manufacturer instructions. During PSCAA Stage 1 burn bans, recreational fires using seasoned wood remain allowed, but Stage 2 bans prohibit them entirely. Renton Regional Fire Authority responds to complaints. Neighbors who report smoke intrusion or nuisance smells can trigger civil infractions. Check pscleanair.gov before lighting a fire during summer stagnation or winter inversions.
