Fairfax Garage Permit Cost (2026)
New detached garage building permit fees in Fairfax County, Virginia, pulled from Appendix Q of the FY2025 Land Development Services Fee Schedule on fairfaxcounty.gov. Unlike alterations and demolition - which Fairfax prices at 3% of declared value - a new garage is new construction priced per square foot by construction type. A typical wood-frame detached garage (Type VA/VB, ICC Group U) is charged $0.143 per square foot as the building permit, plus 50% of the building permit fee as plan review, plus a 2% Virginia state levy on the combined building permit and plan review subtotal. The minimum building permit fee is $72, which produces a $110.16 all-in floor. Because $72 divided by $0.143 is about 503 square feet, the minimum binds for nearly every standard detached garage: a 240 sq ft 1-car garage and a 440 sq ft 2-car garage both land at $110.16 all-in. A 720 sq ft oversized 3-car garage runs $157.53, and a 900 sq ft garage with workshop runs $196.91. This makes Fairfax - usually the most expensive verified Virginia jurisdiction for value-based work - one of the cheapest for a new detached garage. An electrical sub-permit for lighting and outlets is required separately and is not included in the all-in figure.
This guide covers: Fairfax County, Virginia new detached garage building permit fees under the Appendix Q new-construction per-square-foot conventions captured from the FY2025 Land Development Services Fee Schedule on fairfaxcounty.gov. Coverage includes the per-square-foot building permit rate by construction type (wood frame Type VA/VB / ICC Group U at $0.143 per sq ft, the typical residential detached garage), the 50% plan review fee calculated on the building permit fee, the 2% Virginia USBC state levy applied to the combined building permit and plan review subtotal, and the $72 minimum building permit fee. The four worked examples below cover standard detached garage scopes from a 240 sq ft 1-car garage through a 900 sq ft garage with workshop.
This guide does NOT cover: The electrical sub-permit required for garage lighting, outlets, and any sub-panel - this is a separate trade permit filed under Fairfax's electrical schedule and is NOT included in the all-in building permit figure. A plumbing sub-permit is required separately if a utility sink or hose bibb is added. Higher per-square-foot rates apply to non-combustible construction types - Type IIA/IIIA/IV is $0.211 per sq ft and Type IA/IB is $0.270 per sq ft - so a masonry or steel garage costs more than the wood-frame figures shown here. Attached garages may be filed differently from a detached accessory structure (confirm classification with Fairfax County Land Development Services). Zoning and setback review, lot-coverage limits, and any HOA architectural review are separate from the building permit. The per-square-foot new-construction building permit is a distinct line item from the 3% alteration formula that applies to renovations and the demolition of an existing garage.
Why a new garage is priced differently from an alteration: Fairfax County prices new construction - including a new detached garage - by the building's square footage and construction type, not as a percentage of the declared project value. Alterations, repairs, and demolition of existing structures use the 3% of declared value formula. This is the single most important distinction for budgeting a garage: at a low per-square-foot rate, the $72 minimum building permit absorbs most standard garages, so the all-in fee stays near $110.16 even when the contractor's build cost is $25,000 or more. The percentage-of-value formula that makes Fairfax expensive for renovations does not apply to new garage construction.
Sub-permits and review you still need: A garage with electrical service (lights, outlets, a door opener circuit, or a sub-panel) requires a separate electrical sub-permit. If you add a utility sink, a floor drain, or a hose bibb, a separate plumbing sub-permit applies. Detached garage placement must satisfy Fairfax County zoning setbacks and accessory-structure lot-coverage limits, and an HOA may require architectural review. None of these are part of the building permit fee shown in the worked examples - budget and schedule them separately.
A new detached garage building permit in Fairfax County is priced per square foot by construction type: a typical wood-frame garage is $0.143 per sq ft as the building permit, plus 50% of the building permit as plan review, plus 2% Virginia state levy on the combined subtotal. Minimum building permit fee is $72 ($110.16 all-in). Because $72 divided by $0.143 is about 503 sq ft, the minimum binds for most standard garages: a 240 sq ft 1-car garage and a 440 sq ft 2-car garage both run $110.16. A 720 sq ft 3-car garage runs $157.53 ($102.96 BP + $51.48 PR + $3.09 levy). A 900 sq ft garage with workshop runs $196.91. The electrical sub-permit for lighting and outlets is filed separately and is not included. Source: Appendix Q FY2025 Land Development Services Fee Schedule, fairfaxcounty.gov.
- A new detached garage is new construction in Fairfax, priced per square foot by construction type - not by the 3% of declared value formula that applies to alterations and the demolition of an existing garage. Wood frame (Type VA/VB, ICC Group U), the typical residential detached garage, is $0.143 per sq ft as the building permit.
- Minimum building permit fee is $72. With the 50% plan review ($36) and the 2% levy on the combined $108 subtotal ($2.16), the all-in floor is $110.16. Because $72 divided by $0.143 is about 503 sq ft, the $72 minimum binds for nearly every standard detached garage.
- A 240 sq ft 1-car garage ($34.32 calculated, below the $72 minimum) and a 440 sq ft 2-car garage ($62.92 calculated, still below $72) both land at the $110.16 all-in minimum floor. The per-square-foot rate only begins to govern above roughly 503 sq ft.
- A 720 sq ft oversized 3-car garage is the first standard scope where the formula exceeds the minimum: 720 x $0.143 = $102.96 building permit, $51.48 plan review, $154.44 subtotal, $3.09 levy, $157.53 all-in. A 900 sq ft garage with workshop runs $196.91 all-in.
- Fairfax - usually the most expensive verified Virginia jurisdiction for value-based work (alterations and demolition at 3% of declared value) - is one of the cheapest for a new detached garage, precisely because it prices new construction per square foot at a low rate rather than as a percentage of build cost.
- The electrical sub-permit for garage lighting, outlets, and any sub-panel is a separate trade permit and is NOT included in the all-in building permit figure. A plumbing sub-permit applies separately if you add a utility sink, floor drain, or hose bibb.
- Higher per-square-foot rates apply to non-combustible construction: Type IIA/IIIA/IV is $0.211 per sq ft and Type IA/IB is $0.270 per sq ft. A masonry or steel garage costs more than the wood-frame figures in this guide - confirm your construction type before budgeting.
- Compared to other jurisdictions, a standard 2-car detached garage ($25,000 build, 440 sq ft) costs $110.16 in Fairfax, $224.40 in Henrico County (value-based), $340.70 in Chesterfield County (flat fee), and $71.50 in Washington, DC (flat fee). Methods differ - each jurisdiction prices garages on a different basis.
- Zoning setbacks, accessory-structure lot-coverage limits, and any HOA architectural review are separate from the building permit. Confirm detached garage placement and whether your structure is classified as detached or attached with Fairfax County Land Development Services at (703) 222-0801 before filing.
Fairfax Garage Permit Fee Components
A new wood-frame detached garage building permit splits into three components: the building permit (square footage x $0.143, minimum $72), the plan review fee (50% of the building permit), and the 2% Virginia state levy on the combined building permit and plan review subtotal. The component breakdown below shows the math at the four standard garage scopes - from a 240 sq ft 1-car garage through a 900 sq ft garage with workshop. Note that the two smaller scopes both fall under the $72 minimum building permit, so the minimum governs and the all-in fee is identical.
| Component | 1-car, 240 sq ft ($15k) | 2-car, 440 sq ft ($25k) | 3-car, 720 sq ft ($40k) | Workshop, 900 sq ft ($60k) |
|---|---|---|---|---|
| Building permit ($0.143/sq ft, min $72) | $72.00 (min) | $72.00 (min) | $102.96 | $128.70 |
| Plan review (50% of BP) | $36.00 | $36.00 | $51.48 | $64.35 |
| BP + PR subtotal | $108.00 | $108.00 | $154.44 | $193.05 |
| 2% Virginia state levy | $2.16 | $2.16 | $3.09 | $3.86 |
| All-in garage permit total | $110.16 | $110.16 | $157.53 | $196.91 |
Source: Fairfax County Appendix Q FY2025 Land Development Services Fee Schedule, new-construction per-square-foot line item. Figures use the wood-frame (Type VA/VB, ICC Group U) rate of $0.143 per sq ft, which is the typical residential detached garage. The 50% plan review fee and 2% Virginia state levy are applied per Appendix Q, and the $72 minimum building permit binds for any wood-frame garage up to about 503 sq ft ($72 divided by $0.143). The declared values in parentheses are representative contractor build costs for each scope - they do not affect the building permit fee, which is driven by square footage. The electrical sub-permit for garage lighting and outlets is filed separately and is NOT included. Non-combustible construction (Type IIA/IIIA/IV at $0.211 per sq ft, Type IA/IB at $0.270 per sq ft) costs more than the figures shown.
Worked Examples - Real Detached Garage Projects in Fairfax
The four worked examples below cover typical Fairfax wood-frame detached garage scopes from a 240 sq ft 1-car garage through a 900 sq ft garage with workshop. The first two scopes fall under the $72 minimum building permit, so both land at the $110.16 all-in floor. The electrical sub-permit for lighting and outlets, any plumbing sub-permit, and zoning or HOA review are filed separately and are NOT included.
A homeowner builds a 240 sq ft single-car wood-frame detached garage on a concrete slab, with a contractor build cost of about $15,000. Construction type is Type VB (wood frame, ICC Group U), so the per-square-foot rate is $0.143. The square-footage calculation comes to $34.32 - well below the $72 minimum building permit - so the $72 minimum governs. The build cost does not change the building permit fee; only the square footage and construction type matter.
- Square footage: 240 sq ft
- Calculated rate (240 x $0.143): $34.32 (below $72 min)
- Building permit (minimum applies): $72.00
- Plan review (50% of BP): $36.00
- BP + PR subtotal: $108.00
- 2% Virginia state levy (on $108 subtotal): $2.16
- Garage permit total: $110.16 (minimum floor)
Note: the $110.16 all-in is the minimum floor for any wood-frame garage up to about 503 sq ft. Add a separate electrical sub-permit for garage lighting and outlets. The same 240 sq ft / $15,000 garage costs $163.20 in Henrico County, $340.70 in Chesterfield County, and $71.50 in Washington, DC.
A homeowner builds a 440 sq ft standard two-car wood-frame detached garage with a contractor build cost of about $25,000. At $0.143 per sq ft the calculation comes to $62.92 - still below the $72 minimum building permit - so the minimum governs and the all-in fee matches the smaller 1-car garage. This is the single most common detached garage scope in Fairfax, and it sits squarely under the minimum floor.
- Square footage: 440 sq ft
- Calculated rate (440 x $0.143): $62.92 (below $72 min)
- Building permit (minimum applies): $72.00
- Plan review (50% of BP): $36.00
- BP + PR subtotal: $108.00
- 2% Virginia state levy (on $108 subtotal): $2.16
- Garage permit total: $110.16 (still minimum floor)
Note: the $72 minimum building permit binds for wood-frame garages up to about 503 sq ft ($72 divided by $0.143), so a 440 sq ft 2-car garage stays at the $110.16 floor. A $25,000 build cost would cost far more under a percentage-of-value formula - this is exactly why Fairfax is cheap for new garages but expensive for the alteration of an existing one.
A homeowner builds a 720 sq ft oversized three-car wood-frame detached garage with a contractor build cost of about $40,000. At 720 sq ft the per-square-foot calculation ($102.96) finally exceeds the $72 minimum, so the square-footage rate governs. This is the first standard garage scope where the formula, not the minimum, sets the building permit.
- Square footage: 720 sq ft
- Building permit (720 x $0.143): $102.96
- Plan review (50% of BP): $51.48
- BP + PR subtotal: $154.44
- 2% Virginia state levy (on $154.44 subtotal): $3.09
- Garage permit total: $157.53
Note: at 720 sq ft the building permit is driven by square footage, not the $72 minimum. Add a separate electrical sub-permit for lighting, outlets, and any sub-panel. A garage of this size with a workbench area commonly adds an electrical sub-permit and, if a utility sink is included, a plumbing sub-permit - both filed separately.
A homeowner builds a 900 sq ft wood-frame detached garage with an attached workshop bay and a contractor build cost of about $60,000. At 900 sq ft the per-square-foot calculation ($128.70) governs. The structure includes a workshop area with planned electrical and a utility sink - both of which require separate sub-permits not reflected in the building permit total below.
- Square footage: 900 sq ft
- Building permit (900 x $0.143): $128.70
- Plan review (50% of BP): $64.35
- BP + PR subtotal: $193.05
- 2% Virginia state levy (on $193.05 subtotal): $3.86
- Garage permit total: $196.91
Note: at 900 sq ft and a $60,000 build cost, Fairfax's $196.91 building permit compares against Henrico $438.60, Chesterfield $340.70 flat, and Washington, DC $71.50 flat (a large garage may reclassify to DC's $0.03/cu ft rate). The workshop's electrical sub-permit and the utility-sink plumbing sub-permit are additional and filed separately.
Calculate Your Fairfax Garage Permit
The PermitPrice fee calculator supports Fairfax County's new-construction per-square-foot garage formula. Pick "Fairfax County, VA" in the jurisdiction dropdown, choose the new-construction garage project type, and enter the square footage and construction type. For a wood-frame garage the calculator applies the $0.143 per sq ft rate, the $72 minimum building permit, the 50% plan review, and the 2% state levy to produce the all-in fee. For a 600 sq ft wood-frame garage: 600 x $0.143 = $85.80 BP, $42.90 PR, subtotal $128.70, levy $2.57, all-in $131.27. The electrical sub-permit for lighting and outlets must be budgeted separately.
Fairfax garage rule of thumb: For a wood-frame garage, all-in fee = $110.16 (any garage up to about 503 sq ft) or square footage x $0.143 x 1.53 (above 503 sq ft). At 440 sq ft: $110.16. At 720 sq ft: $157.53. At 900 sq ft: $196.91. Add a separate electrical sub-permit for lighting and outlets, and use the higher $0.211 or $0.270 per sq ft rate for non-combustible construction.
Open the Permit Fee CalculatorElectrical Sub-Permit and Construction-Type Rates - Not in the All-In
The all-in figures in this guide cover only the new-construction building permit, the 50% plan review, and the 2% state levy for a wood-frame garage. A garage with any electrical service requires a separate electrical sub-permit, and a higher per-square-foot rate applies if the garage is built from non-combustible materials. Both can change your true total significantly.
Electrical sub-permit (separate): Almost every garage gets lights, outlets, a garage-door-opener circuit, and often a sub-panel. That electrical work requires a separate electrical sub-permit filed under Fairfax's trade schedule - it is NOT included in the building permit all-in figures above. Plan to file the electrical sub-permit alongside the building permit, and confirm the current trade fee with Fairfax County Land Development Services.
Plumbing sub-permit (if applicable): If the garage includes a utility sink, a floor drain, or a hose bibb, a separate plumbing sub-permit applies. A dry garage with no plumbing does not need this permit. As with electrical, the plumbing sub-permit is filed separately and is not part of the building permit all-in.
Construction-type rate (changes the building permit): The $0.143 per sq ft rate applies to wood frame (Type VA/VB, ICC Group U) - the typical residential detached garage. A garage built from non-combustible materials is charged at a higher rate: Type IIA/IIIA/IV is $0.211 per sq ft, and Type IA/IB is $0.270 per sq ft. For a 720 sq ft garage, a Type IIA/IIIA/IV structure would be charged $151.92 building permit instead of $102.96 - a meaningful difference. Confirm your construction type before relying on the wood-frame figures.
Zoning, setbacks, and HOA review (separate): Detached garage placement must satisfy Fairfax County zoning setbacks and accessory-structure lot-coverage limits, and an HOA may require architectural review before construction. These approvals are separate from the building permit and are not reflected in any fee shown here. Attached garages may be filed under a different classification than a detached accessory structure - confirm with Fairfax County Land Development Services at (703) 222-0801.
Fairfax Garage Permit Cost vs Neighbors
Fairfax is one of the cheapest verified jurisdictions for a new detached garage, because it prices new construction per square foot at a low rate ($0.143/sq ft wood frame) rather than as a percentage of build cost. The table below compares the all-in garage permit cost across the verified cluster at four standard scopes. Each scope lists both the square footage and the declared build value so every pricing method can be applied.
| Jurisdiction | Pricing Method | 1-car, 240 sq ft, $15k | 2-car, 440 sq ft, $25k | 3-car, 720 sq ft, $40k | Workshop, 900 sq ft, $60k |
|---|---|---|---|---|---|
| Fairfax County | $0.143/sq ft (wood frame, $72 min) + 50% PR + 2% levy | $110.16 | $110.16 | $157.53 | $196.91 |
| Henrico County | $100 + $6/$1k over $5k (cap $680 BP) + 2% levy | $163.20 | $224.40 | $316.20 | $438.60 |
| Chesterfield County | Flat $285 + $50 Environmental Eng + 2% levy | $340.70 | $340.70 | $340.70 | $340.70 |
| Washington, DC | Flat $65 + 10% Enhanced | $71.50 | $71.50 | $71.50 | $71.50 |
Methods differ - Fairfax and DC price garages as new construction (square footage / cubic footage), Henrico by declared value, Chesterfield by flat fee; each scope lists both square footage and declared value so every jurisdiction can be priced. Loudoun, Norfolk, Richmond, and Virginia Beach are not shown because their official fee schedules carry no discrete new-detached-garage line item.
