Fire Pit and Outdoor Fireplace Cost in Orange County: 2026 Guide

A fire feature is one of the highest-impact additions to a backyard in Orange County. It extends evening use of the outdoor space year-round, creates a natural gathering point, and adds visual appeal that photographs well for both resale and short-term rentals. But the cost range between a basic fire pit and a built-in outdoor fireplace is enormous, and so is the regulatory landscape. OC's fire codes, HOA restrictions, and gas-line requirements all affect what's possible and what a project will cost. Here's what to expect.

Fire Pit vs. Outdoor Fireplace: Cost Comparison

Feature Type	Tier	Estimated Cost (OC Installed)
Built-in fire pit (gas)	Basic	$2,000 to $4,500
Built-in fire pit (gas + stone surround)	Mid-range	$5,000 to $10,000
Built-in fire pit (premium masonry + seating wall)	Premium	$10,000 to $25,000+
Outdoor fireplace (prefab insert)	Basic	$3,000 to $8,000
Outdoor fireplace (built-in, stucco or stone)	Mid-range	$8,000 to $25,000
Outdoor fireplace (full masonry, custom surround)	Premium	$20,000 to $50,000+

The key cost driver separating tiers is the surround material and whether the fireplace or fire pit is integrated into a larger outdoor structure. A simple gas fire pit bowl set into a concrete surround sits at the low end. A full masonry outdoor fireplace with a custom stone mantle, integrated seating walls, and a flagstone hearth sits at the high end. Both categories assume gas-plumbed installations, which require a permit; wood-burning fire pits in most of Orange County are additionally restricted by air quality rules (see below).

Gas Line Cost

Running a new gas line to the fire feature is almost always required unless the yard already has an exterior gas stub-out from a previous appliance. Gas line installation runs $15 to $25 per linear foot in Orange County, with a typical backyard run of 40 to 80 feet adding $600 to $2,000 to the project. If the main gas service or meter needs to be upsized to accommodate additional appliances (particularly if you're also adding an outdoor kitchen), that can add $1,500 to $4,000 for service upgrade work coordinated with SoCalGas.

Orange County Setback and Fire Code Requirements

OC fire codes apply across incorporated cities and unincorporated areas, with some variation by jurisdiction. General rules that apply broadly:

• Permanent fire features must be at least 7 feet from property lines and 10 feet from structures, fences, or combustible materials.
• Gas-plumbed fire features require a mechanical or building permit in virtually all OC cities. Unpermitted gas installations are a significant liability and are flagged during resale inspections.
• Wood-burning outdoor fire pits are banned on Spare the Air days (typically May to October) in the South Coast AQMD jurisdiction, which covers all of Orange County. Many homeowners opt for gas-only installations to avoid operational restrictions entirely.
• Homes in WUI (Wildland Urban Interface) zones, particularly hillside areas in Lake Forest, Laguna Hills, and unincorporated foothill areas, face more restrictive requirements. See our 2026 WUI code guide for details.

HOA Considerations

Most planned communities in Orange County require HOA architectural committee approval for any permanent outdoor structure, including fire features. Some HOAs in Irvine and Mission Viejo prohibit wood-burning fires entirely regardless of AQMD rules. Gas-fueled fire features are generally permittable but require submittal with dimensions, gas line routing, and finish materials before city permits are pulled. Budget 4 to 8 weeks for HOA review and incorporate it into your project timeline.

What to Pair With a Fire Feature

Fire features are most effective when they're part of a cohesive outdoor living design rather than standalone elements dropped into a yard. The projects we see get the most use pair a fire feature with integrated seating (a concrete or stone seating wall around a fire pit, or built-in benches flanking an outdoor fireplace) and adequate lighting so the space functions after dark beyond just the fire glow. For a full outdoor living build that includes fire, seating, and lighting, see our backyard landscaping cost guide.
