There’s nothing quite like a fire pit on a cool Utah evening — the glow, the warmth, the stories. But when it comes to building a fire pit on a deck, there’s a right way to do it… and a really dangerous way. Whether you're a contractor looking to get ahead of the next client request or a homeowner dreaming up your perfect backyard hangout, this guide will walk you through everything you need to know to design a safe, stunning, and code-compliant fire pit deck.
1. Is It Legal to Put a Fire Pit on a Deck in Utah?
Short answer: yes — but it depends on how you build it and where you live.
Most cities along the Wasatch Front (Salt Lake City, Lehi, Provo, Ogden, etc.) allow gas fire pits on decks if they meet local fire codes. Here are a few key safety guidelines that typically apply across Utah:
Open flame (wood-burning) fire pits are not recommended or allowed on combustible decking.
Gas fire pits (natural gas or propane) are preferred for decks.
A non-combustible base (stone, metal, concrete) must be used beneath the fire feature.
Clearance requirements: Usually 3+ feet from any railing or structure, and 10+ feet vertically from overhangs or pergolas.
Some cities require a permit or inspection if you're running gas lines or hardwiring electrical.
Tip: Always double-check with your local city building office. Salt Lake City and Utah County may have slightly different fire safety requirements.
2. Best Decking Materials for a Fire Pit Area
Not all decking is created equal when you’re dealing with heat and flame. While traditional wood decking can warp, crack, or ignite under intense heat, composite decking (like TimberTech) offers much better resistance — but still isn’t fireproof.
Here’s a breakdown of your safest bets:
🔥 Best Options:
Concrete or stone inlays: Create a designated fire pit zone inset into the deck surface.
Steel or aluminum decking panels under or around the pit.
Fire-rated pavers placed on a built-up deck section.
⚠️ Use with Caution:
Composite decking: Heat-resistant but still needs clearance and protection. TimberTech boards with Class A Flame Spread ratings are a smart pick.
Wood decking: Only if fire pit is placed on a protective platform and there's proper clearance.
3. Design Inspiration: Zoned Layouts and Custom Features
Adding a fire pit isn’t just about warmth — it can anchor the whole design of your deck. Salt Lake City deck builders are using fire features as focal points, often with multi-zone layouts to make the space more functional.
Hot design trends for 2025:
Sunken fire pit lounges: A few steps down with wraparound seating.
Corner fire pit zones: Perfect for maximizing space on rectangular decks.
Built-in gas fire tables: Sleek, permanent, and low-maintenance.
Circular deck extensions: A rounded section just for the fire feature, set slightly apart from the main deck.
And don’t forget accessories — like hidden propane tank storage, wind guards, and matching composite seating.
4. Safety Add-Ons and Maintenance Tips
Fire pits are fun — but they demand respect. These safety features not only meet code, but also keep your client (or family) from dealing with a dangerous flare-up:
Glass wind guards: Keep flames controlled and reduce heat radiation to decking.
Heat deflectors: Installed under the pit to protect decking from heat.
Timer controls or auto shut-off valves: Especially important for Airbnb or rental properties.
Fire-resistant mats or pads: A simple upgrade for portable pits or temporary setups.
Bonus: If you're installing a fire pit on a second-story deck, a heat barrier underneath is non-negotiable.
