Frequently Asked Questions

Do I need a permit to build a backyard fire pit?
It depends on your location. Many cities and counties require a permit for permanent fire pits and set minimum distances from structures — commonly 10–25 feet. Portable fire pits generally don't require permits, but open-burning rules still apply. Check with your local fire marshal or building department before starting.
What is the cheapest way to build a fire pit?
The most budget-friendly option is a simple DIY ring made from retaining-wall blocks arranged in a circle on a gravel base. Materials can cost as little as $50–$150, and no mortar or special tools are required. Pair it with inexpensive folding chairs for a functional fire pit area under $200.
How deep should the gravel base be under a fire pit?
A depth of 4–6 inches of gravel or pea gravel is standard. This provides drainage, insulates the ground from heat, and creates a stable, level surface. For a 10–12 foot diameter area, you'll typically need 3–5 cubic feet of gravel — roughly 3–5 standard 50-lb bags.
How much does a gas fire pit cost compared to a wood-burning one?
Gas fire pits (propane or natural gas) typically cost $300–$1,500 for the unit, plus $200–$600 or more if a plumber needs to run a gas line. Wood-burning pits range from $50 for a portable ring to $1,500+ for custom masonry.
What type of seating works best around a fire pit?
All-weather materials like powder-coated steel, teak, cedar, concrete, or HDPE lumber hold up best near heat and moisture. Adirondack chairs, curved sectional benches, and Muskoka chairs are popular choices. Maintain at least 3 feet of clearance between seating and the fire pit edge.

How Much Does a Backyard Fire Pit Cost?

A backyard fire pit is one of the most rewarding weekend projects you can tackle — but costs add up quickly once you account for the pit itself, base prep, seating, tools, and wood storage. The calculator above breaks your budget into the five main spending categories so there are no surprises on install day.

Fire Pit Kit vs. Building from Scratch

Pre-made steel or cast-iron fire pit kits typically run $50–$400 for portable models and $200–$900 for in-ground or ring kits. Building a DIY stone or brick pit from scratch can cost as little as $100–$300 in materials. Custom masonry or gas-insert fire pits can push past $2,000 once permits and professional installation are included.

Gravel Base and Ground Prep

Most fire pits need a non-combustible base — typically 4–6 inches of gravel in a 10–12 ft diameter circle. Budget $40–$150 for gravel bags, landscape fabric, and edging. If your ground is uneven you may need to add another $50–$200 for supplies or labor.

What's a Realistic Total Budget?

  • Under $300 — Basic portable steel pit, simple gravel patch, folding chairs.
  • $300–$700 — DIY stone ring with solid seating and a wood rack.
  • $700–$1,500 — Pre-built masonry kit, matching outdoor furniture set, full accessories.
  • $1,500+ — Custom gas or masonry pit, permanent built-in seating, professional installation.
