Fire Pit Safety: Clearance Requirements, Deck Rules, and What Your Local Code Actually Says
The quick answer: Keep any fire pit at least 10 feet from structures, 20 feet from branches, and never on a wood deck without a rated fire pit pad and manufacturer approval. Gas fire pits are safer on decks than wood-burning. Call your local fire department before buying — it's a free 5-minute call.
Clearance Requirements: The Non-Negotiable Distances
House, garage, shed: 10 feet minimum (some codes require 15). Wooden fence: 10 feet. Overhanging trees/branches: 20 feet. Property line: 10–15 feet. Check your local ordinance for specific requirements.
Seating: 3–4 feet from flame edge. Combustible furniture: 4+ feet. Minimum 20 feet of clear sky above a wood-burning pit, 8+ feet above a gas pit under a covered structure.
Fire Pits on Decks
Wood Decks
Wood-burning on wood deck: NO. Full stop. The radiant heat plus ember risk makes this a genuine hazard. Most fire codes prohibit it.
Gas on wood deck: MAYBE. Check: 1) manufacturer specs (many say 'not for combustible surfaces'), 2) use a rated fire pit pad (DeckProtect brand recommended), 3) deck warranty, 4) homeowner's insurance.
Composite Decks
Composite decking (Trex, TimberTech) is MORE susceptible to heat than natural wood — it softens and discolors at lower temperatures. Requires manufacturer's explicit approval, which most don't give.
Concrete/Stone Patios
The safest surface. No special precautions beyond standard clearances. This is the ideal fire pit surface.
Local Fire Codes
You're subject to whichever is most restrictive: municipal code, county code, state code, or HOA rules. Fastest way to check: call your local fire department non-emergency number. Tell them what you're planning. They'll tell you everything you need to know in 5 minutes.
Gas fire pits usually don't require permits. Wood-burning often do. Natural gas line installation always requires a permit. HOAs commonly prohibit wood-burning entirely and may require architectural review for gas.

Frequently Asked Questions
How far should a fire pit be from the house?
Minimum 10 feet, 15 feet in many jurisdictions. Check your local fire code. Maintain 20 feet from overhanging branches.
Do you need a permit for a fire pit?
Gas: usually no. Wood-burning: often yes. Gas line installation: always yes. Call your local fire department — free and takes 5 minutes.
What is the safest type of fire pit?
Gas fire pits with electronic ignition, a wind guard, and proper clearances. No sparks, no embers, instant off. Fire tables are safer than open bowls because the ledge creates a natural barrier.
Can you use a fire pit in the rain?
Gas fire pits work in light rain. Heavy rain extinguishes wood fires. After rain, check gas connections and dry the ignition area before lighting. Use a fitted cover between uses.
