Fire Pits & Fireplaces in Mount Vernon, Virginia
Fairfax County requires a mechanical permit for gas piping and combustion work on any built-in fire feature, and the Fire Marshal's office is specific about clearance from structures, fencing, and combustible material \— rules that exist because homes here sit close together, decks are wood, and dry autumn leaves collect against foundations.
The Short Answer
A fire feature is the easiest way to add a fourth season to a Mount Vernon backyard. Lawn Theory builds wood-burning fire pits from $2,500–$6,500, gas fire pits from $5,500–$14,000, and full outdoor fireplaces from $15,000–$50,000+ depending on size, stone, and gas-line complexity. Anything with a chimney or a gas line requires a permit in Fairfax, Loudoun, Prince William, Arlington, and Alexandria — we handle submission and inspection so your build doesn't stall. Most single-feature projects take 1–3 weeks to build once permits clear; plan 4–8 weeks ahead of your target season for design and approvals.

Mount Vernon, Answered
Fire Pits & Fireplaces in Mount Vernon — Common Questions
Wood vs. gas fire pit — which is better in Northern Virginia?
Wood is cheaper to build and feels traditional, but it produces smoke and needs regular tending. Gas is cleaner, instant-on, and much easier on neighbors and HOAs that restrict wood-burning. Both are great choices when built with proper footings, clearances, and (for gas) a code-compliant line. Serving Mount Vernon and all of Fairfax County.
Do I need a permit for an outdoor fireplace or fire pit in Loudoun or Fairfax?
Yes — any fire feature with a chimney or a gas line requires a building and/or mechanical permit in Fairfax, Loudoun, Prince William, Arlington, and Alexandria. Simple, unattached wood-burning fire pits sometimes fall outside permit requirements, but we verify this for your specific jurisdiction and handle the submission and inspection either way. Serving Mount Vernon and all of Fairfax County.
Are there HOA restrictions on fire pits in Northern Virginia?
Many NoVA HOAs require design approval before installation, and some — especially master-planned communities in Loudoun and Prince William — restrict or prohibit wood-burning entirely in favor of gas. We've submitted plans to most major communities in the region and can tell you what your HOA is likely to require before you commit to a design. Serving Mount Vernon and all of Fairfax County.
Can I burn fires year-round in Northern Virginia?
Yes, with the right design and clearances. The main exception is temporary burn restrictions that Loudoun and Fairfax counties can issue during dry stretches, which typically apply to open wood fires. Gas and propane fire features are usually unaffected, which is one reason many homeowners choose gas for a true four-season feature. Serving Mount Vernon and all of Fairfax County.
How close can a fire pit be to my house or fence?
Virginia fire code typically requires a minimum 10-foot clearance from any structure or combustible material, though local jurisdictions and HOAs can require more. We design with additional buffer beyond the code minimum for safety, comfort, and long-term resale value. Serving Mount Vernon and all of Fairfax County.
How much does a fire pit or outdoor fireplace cost in Northern Virginia?
Wood-burning fire pits typically run $2,500–$6,500, gas fire pits run $5,500–$14,000, and full outdoor fireplaces with a chimney, hearth, and mantel run $15,000–$50,000 or more. The biggest cost drivers are the base engineering, material tier (pavers vs. natural stone), site conditions, and whether a gas line has to be run. Serving Mount Vernon and all of Fairfax County.
How long does it take to build a fire pit or fireplace?
Most single-feature projects take 1–3 weeks of actual build time once permits and HOA approvals are in hand. Plan on 4–8 weeks of lead time before that for design, permit review, and HOA submission — we recommend starting the process at least two months ahead of your target season. Serving Mount Vernon and all of Fairfax County.
