Fire Regulations in Seattle, WA: What Residents Actually Need to Know

If you live in Seattle or are thinking about moving there, fire regulations are one of those things you probably won't think about until they affect you directly. Seattle has 4 specific rules on the books covering different aspects of fire regulations, and some of them might surprise you.

Propane Storage

The Seattle Fire Code, based on IFC Chapter 61 and amended in SMC Title 22, caps propane cylinder storage at residences and businesses. Cylinders larger than 10 gallons require permits; multifamily storage is tightly limited.

Key details: Code: IFC 6101. Permit threshold: >125 gal water. Balcony storage: Banned >4th floor. Clearance: 10 ft ignition.

Unpermitted commercial storage or unsafe configuration: SFD violation up to $1,500 per day plus order to remove. Multifamily violations may trigger landlord enforcement and tenant evictions.

Fire Pit Rules

Outdoor fire pits and open flames are heavily restricted in Seattle due to the city's general prohibition on open burning. PSCAA burn bans also apply. Chimineas and enclosed fire pits may be subject to city and state air quality rules.

Key details: Open Burning: Prohibited in Seattle city limits. Burn Bans: PSCAA issues (check pscaa.net). State Law: WAC 173-425. Contact: Seattle Fire Department (SFD).

Unattended fire: citation. Prohibited fuel: citation. Burning during burn ban: ticketing and prosecution.

This is not one of those rules that cities tend to ignore. Seattle actively enforces its fire pit rules requirements.

Fireworks

All consumer fireworks are banned in Seattle. Violations are gross misdemeanors punishable by up to 1 year in jail and/or a $5,000 fine. Ceremonial fireworks may be permitted via a Seattle Fire Department no-fee permit (SFD CAM 5033).
