Renton requires vegetation management as a nuisance matter under RMC 1-3-3. Wildland-urban interface areas around May Creek and Cedar River require 30-foot defensible space under IFC Chapter 49.
Renton Municipal Code 1-3-3 defines overgrown vegetation that poses a fire hazard as a public nuisance subject to abatement. Under International Fire Code Chapter 49 (Wildland-Urban Interface, adopted via RMC 4-5-070), property owners in designated WUI areas must maintain defensible space extending 30 feet from structures. Zone 1 (0 to 5 feet from structure) should have no combustible vegetation, mulch, or wood piles. Zone 2 (5 to 30 feet) requires pruned trees with crowns separated by at least 10 feet, ladder fuels removed, and grass kept short. Zone 3 (30 to 100 feet) requires thinning of dense brush. Renton's WUI includes neighborhoods bordering May Creek, Cedar River canyon, Cougar Mountain, and forested areas east of I-405. Dead trees, dry brush, and accumulated leaves must be removed promptly. Critical areas protections under RMC 4-3-050 can restrict clearing in wetland buffers and steep slope zones, so owners should check with Community and Economic Development before major clearing. Renton Regional Fire Authority offers free wildfire home hazard assessments.
Nuisance abatement under RMC 1-3-3 with costs assessed to owner. Civil infractions under RMC 1-10. Critical area violations can trigger WDOE enforcement and restoration orders.
