Fairfax County Alteration Permit Cost (2026)
Residential alteration permit fees in Fairfax County, Virginia, pulled from the Fairfax County Land Development Services Appendix Q FY2025 fee schedule. Fairfax applies a uniform 3% of declared construction cost formula to residential alterations and repairs covering kitchen remodels, bathroom remodels, basement finishes, interior renovations, and most home-improvement permit categories. The building permit fee is computed as 3% of declared value, with a minimum of $72. The plan review fee is 50% of the building permit fee. The 2% Virginia state levy applies to the combined building permit subtotal (building permit + plan review). Minimum all-in alteration permit is $110.16 for any alteration under $2,400 declared value. A $5,000 minor kitchen update runs $229.50 all-in. A $15,000 bathroom remodel runs $688.50. A $30,000 kitchen remodel runs $1,377.00. A $50,000 whole-home update runs $2,295.00. A $100,000 full gut remodel runs $4,590.00. The 3% formula is uncapped, producing dramatically higher alteration permit fees than value-based jurisdictions outside DMV-NOVA.
This guide covers: Fairfax County, Virginia residential alteration and repair permit fees under Appendix Q FY2025 of the Fairfax County Land Development Services fee schedule. Coverage includes the 3% of declared construction cost formula applied to residential alterations and repairs, the $72 minimum building permit fee that creates an effective all-in minimum of $110.16, the 50% plan review fee calculated on the building permit fee, and the 2% Virginia USBC state levy applied to the combined building permit subtotal (building permit + plan review). Worked examples cover the typical residential alteration scope range from minor under-$500 repairs through $100,000 full gut renovations. Coverage also includes the kitchen_remodel and similar interior project lines that apply the same 3% rate.
This guide does NOT cover: Trade permit fees (electrical, plumbing, mechanical) for the alteration scope - these are filed separately under Fairfax's trade permit fee tables (residential electrical 0-149 amp, 150-399 amp, 400-599 amp; residential plumbing 1-5 fixture, 6-15 fixture; residential mechanical 1-zone, 2-3 zone); commercial alterations (similar 3% structure with different inspection processes); new construction or additions that extend the heated envelope (handled by Fairfax's new_construction_residential category at the same 3% rate but with different scope); zoning approvals required before permit submission (lot coverage limits, setback compliance, special exception permits, variance applications); HOA architectural review (not a county process); the cost of materials, labor, or construction itself; downstream property tax reassessment if the alteration increases assessed home value.
Important - the 3% formula is uncapped: Fairfax's residential alteration rate of 3% of declared construction cost has NO cap, unlike Henrico County (caps at $680 building permit + 2% levy = $693.60 all-in at $101,667 declared value). A $200,000 declared whole-home renovation runs $6,000 building permit + $3,000 plan review = $9,000 subtotal + $180 levy = $9,180 all-in in Fairfax. The same project in Henrico hits the cap at $693.60. The lack of a cap is the single largest structural reason Fairfax alteration permits are the most expensive in the verified DMV cluster at typical residential scope.
Note on declared construction value: The valuation basis is "applicant_stated_or_ICC_BVD_whichever_greater" per the Appendix Q valuation rules. The Fairfax inspector compares the applicant-stated declared value against the ICC Building Valuation Data (BVD) standard for the alteration scope; the greater of the two is used for the 3% formula. This protects against under-declaration but does not affect honest declarations at typical residential scope - most kitchen and bathroom remodel scopes stated honestly will exceed the BVD floor and the applicant-stated value will govern. Confirm declared value with your contractor before filing; the BVD comparison is rare to trigger for residential interior work but is the rule.
A residential alteration permit in Fairfax County costs 3% of declared construction value for the building permit, plus 50% of the building permit fee for plan review, plus the 2% Virginia state levy on the combined building permit subtotal. Minimum building permit fee $72, producing an effective all-in minimum of $110.16 for alterations under $2,400 declared value. A $5,000 minor kitchen update runs $229.50 all-in ($150 BP + $75 PR = $225 + $4.50 levy). A $15,000 bathroom remodel runs $688.50 ($450 + $225 = $675 + $13.50 levy). A $30,000 kitchen remodel runs $1,377.00 ($900 + $450 = $1,350 + $27 levy). A $50,000 whole-home update runs $2,295.00. A $100,000 full gut remodel runs $4,590.00. The 3% formula is uncapped and produces dramatically higher alteration permit fees than value-based VA jurisdictions outside DMV-NOVA. Trade permits (electrical, plumbing, mechanical) filed separately on top of the building permit at Fairfax's amperage/fixture/zone tier tables.
- Fairfax residential alteration permits follow a uniform 3% of declared construction value formula. Kitchen remodels, bathroom remodels, basement finishes, interior renovations, and all home-improvement work classified as residential_alteration_repair use the same rate. The plan review fee adds 50% of the building permit fee on top, and the 2% Virginia state levy applies to the combined building permit subtotal.
- The minimum building permit fee is $72, producing an effective all-in minimum of $110.16 for alterations under $2,400 declared value. Below the $2,400 threshold the building permit pegs at $72 ($72 BP + $36 PR = $108 subtotal + $2.16 levy = $110.16). Above $2,400 the formula scales linearly at 3% of declared value.
- The 3% formula is uncapped. A $100,000 declared alteration runs $4,590 all-in. A $250,000 luxury whole-home gut renovation runs $11,475 all-in. A $500,000 estate-grade renovation runs $22,950 all-in. There is no fee cap that would freeze the building permit at a maximum. This is structurally different from Henrico County (capped at $680 BP + 2% levy = $693.60 all-in) where alteration permits cap at $101,667 declared value. The uncapped Fairfax formula is the single largest cost driver for high-value alterations.
- Compared to value-based VA jurisdictions, Fairfax is the most expensive verified jurisdiction for residential alterations at typical scope. A $30,000 kitchen remodel costs $1,377.00 in Fairfax, $735.90 in Washington, DC (4-tier formula + 10% Enhanced + GBF), $255.00 in Henrico County, $237.62 in Richmond City, $314.00 in Virginia Beach, $152.00 in Norfolk City (flat $100 + $35 PR + $15 + 2% levy on $100), and $402.90 in Loudoun County (bundled flat).
- The 50% plan review surcharge on top of the building permit is unique among the verified DMV cluster - no other VA jurisdiction in the cluster applies plan review as a percentage of the building permit fee. Loudoun bundles plan review into the $395 flat. Henrico does not charge a separate plan review for residential. Richmond does not charge plan review on residential alterations. Virginia Beach charges a flat $100 or $25 counter PR. Norfolk charges tiered PR ($35-$100). DC bundles plan review into the tier fee. Fairfax's 50% plan review surcharge is the structural reason Fairfax is more expensive than every other verified DMV jurisdiction at every alteration scope.
- The 2% Virginia state levy is required by Code of Virginia Section 36-139 and USBC Section 107.2. Fairfax applies it to the combined building permit subtotal (building permit fee + plan review fee). On a $30,000 kitchen remodel: BP $900 + PR $450 = $1,350 subtotal + 2% levy = $27.00. Total $1,377. The levy is a state-collected pass-through to the Virginia Department of Housing and Community Development - the same statutory authority every Virginia jurisdiction operates under, including jurisdictions where the levy is much smaller in absolute dollars because the BP and PR are themselves smaller.
- Trade permits (electrical, plumbing, mechanical) for alterations are filed SEPARATELY in Fairfax. The residential electrical permit tiers are 0-149 amp ($341), 150-399 amp ($455), 400-599 amp ($568); plumbing tiers are 1-5 fixture ($227) and 6-15 fixture ($341); mechanical tiers are 1-zone ($227) and 2-3 zone ($341). Each trade permit also carries the 2% Virginia state levy. A typical $30,000 kitchen remodel with new circuits + new sink/dishwasher rough-in + minor HVAC adjustment could add $568 to $796 in trade permits on top of the $1,377 building permit, for a total all-in alteration project permit cost of approximately $1,945 to $2,173.
- For projects requiring structural review (load-bearing wall removal, beam installation, footing modifications), Fairfax may require additional engineering review and stamped structural drawings. These are NOT included in the standard plan review fee and would be billed at additional Land Development Services hourly rates. Confirm with Fairfax LDS at (703) 222-0801 if your alteration scope includes structural changes before relying on the 3% + 50% PR figure for budgeting.
Fairfax Alteration Permit Fee Components
Fairfax's residential alteration permit splits into three component lines: the 3% building permit, the 50% plan review surcharge calculated on the building permit, and the 2% Virginia state levy applied to the combined BP + PR subtotal. The breakdown below shows component math at five typical residential alteration scopes from the minimum $110.16 floor through a $100,000 full gut renovation.
| Component | $1,500 minor ($72 min) | $5k kitchen update | $15k bathroom | $30k kitchen | $50k whole-home |

Source: Fairfax County Land Development Services Appendix Q FY2025 fee schedule (residential_alteration_repair and kitchen_remodel line items). The minimum building permit fee is $72; alterations under $2,400 declared value peg at $72 BP regardless of actual percentage math. The 50% plan review surcharge is calculated as 50% of the building permit fee (not 50% of declared value). The 2% Virginia state levy is required by Code of Virginia Section 36-139 and USBC Section 107.2 and is applied to the combined building permit subtotal (BP + PR). Trade permit fees (residential electrical 0-149/150-399/400-599 amp, plumbing 1-5/6-15 fixture, mechanical 1-zone/2-3 zone) under Fairfax's trade tier tables are filed separately and not included in this table.
Worked Examples - Real Alteration Projects in Fairfax County
The four worked examples below cover typical Fairfax residential alteration scopes from a $5,000 minor kitchen update through a $100,000 full gut renovation. Trade permits for electrical, plumbing, and mechanical scope are NOT included - they would be filed separately under Fairfax's residential trade permit fee tables and add their own tier amounts plus 2% state levy on top of the building permit.
A homeowner files an alteration permit for a minor kitchen update: replacement of cabinets and countertops, addition of a new pot-filler faucet over the range (requires plumbing rough-in), upgraded outlets and undercabinet lighting (requires electrical on a new circuit). Contractor invoice: $5,000 (mid-range cabinets + counters + minor plumbing + minor electrical, materials and labor).
- Declared value: $5,000
- Building permit (3% of $5,000): $150.00
- Plan review (50% of $150): $75.00
- Building permit subtotal: $225.00
- 2% Virginia state levy: $4.50
- Building permit total: $229.50
Note: trade permits for the plumbing rough-in (one fixture - the pot filler, $227 plumbing 1-5 fixture tier) and the electrical (new circuit, $341 0-149 amp tier) would be filed separately. Estimated trade permits add $568 on top of the $229.50, for an all-in $797.50 for the kitchen update. The same project in Henrico County runs $102 building permit + 2% levy on whichever trade permits apply. DC charges $150.15 for the same alteration. Fairfax is more expensive than every other verified DMV jurisdiction at this scope because of the 50% plan review surcharge.
A homeowner files an alteration permit for a full bathroom remodel: demolition of existing bathroom, new tile floor and walls, new bathtub or shower, new vanity with sink, new toilet, new exhaust fan with ducting to exterior, all new electrical on dedicated GFCI circuits, full plumbing rough-in for the new fixture layout. Contractor invoice: $15,000 (mid-range bathroom remodel including all rough-ins and finish work).
- Declared value: $15,000
- Building permit (3% of $15,000): $450.00
- Plan review (50% of $450): $225.00
- Building permit subtotal: $675.00
- 2% Virginia state levy: $13.50
- Building permit total: $688.50
Note: trade permits for the full plumbing scope (sink + toilet + tub/shower + exhaust vent = 3-4 fixture, $227 plumbing 1-5 fixture tier) and the electrical (GFCI circuits + exhaust fan + lighting = $341 0-149 amp tier) would be filed separately. Estimated trade permits add $568 on top of the $688.50, for an all-in $1,256.50. The same bathroom remodel runs $384.45 in DC (Tier 3 alteration + 10% Enhanced + GBF), $163.20 in Henrico County, $144.75 in Richmond City. Fairfax's $688.50 is roughly 4x Henrico's all-in figure for the same scope.
A homeowner files an alteration permit for a full kitchen remodel: complete demolition, new cabinets and counters, new island with electrical outlet, new dishwasher rough-in, new range with gas line work, undercabinet and pendant lighting, recessed ceiling lighting, full new electrical panel work to support new circuits, and minor plumbing relocation for the new sink. Contractor invoice: $30,000 (mid-range remodel, full electrical and plumbing scope, no structural changes).
- Declared value: $30,000
- Building permit (3% of $30,000): $900.00
- Plan review (50% of $900): $450.00
- Building permit subtotal: $1,350.00
- 2% Virginia state levy: $27.00
- Building permit total: $1,377.00
Note: trade permits for the electrical (panel work + new circuits at 150-399 amp $455 tier) and plumbing (new sink + dishwasher 1-5 fixture $227 tier) would be filed separately. Estimated trade permits add $682 on top of the $1,377, for an all-in $2,059 for the building + trade permits. The same $30,000 kitchen remodel costs $735.90 in DC (Tier 3 + 10% Enhanced + GBF), $255 in Henrico County, $237.62 in Richmond City. Fairfax is the most expensive verified DMV jurisdiction at this scope; the 50% plan review surcharge accounts for $450 of the $1,377 total.
A homeowner files an alteration permit for a $100,000 full whole-home gut renovation: complete demolition of interior finishes throughout the entire home, new electrical service throughout, full new HVAC system (new ducting, new air handler, condenser replacement, smart thermostats), all new plumbing fixtures and rough-in, full new kitchen, two full new bathrooms, refinished hardwood floors, new drywall throughout, new interior doors and trim, new lighting and outlets throughout, exterior trim touch-up. Contractor invoice: $100,000 (high-end whole-home interior gut renovation, no structural changes, no addition).
- Declared value: $100,000
- Building permit (3% of $100,000): $3,000.00
- Plan review (50% of $3,000): $1,500.00
- Building permit subtotal: $4,500.00
- 2% Virginia state levy: $90.00
- Building permit total: $4,590.00
Note: trade permits for the full scope (electrical 400-599 amp $568 tier + plumbing 6-15 fixture $341 tier + mechanical 2-3 zone $341 tier) would be filed separately. Estimated trade permits add $1,250 on top of the $4,590, for an all-in approximately $5,840 for the building + trade permits. The same $100,000 gut renovation costs $693.60 all-in in Henrico County (capped at $680 BP + 2% levy = $693.60), approximately $620.46 in Richmond City ($63 + $594.86 = $657.86 + 2% levy = $670.41 - actually slightly different), and $2,376 in DC ($30 + $2,000 = $2,030 + 10% = $2,233 BP + $130 GBF + $13 Enhanced = $143 GBF, total $2,376). Fairfax's $4,590 is roughly 6.6x Henrico's $693.60 all-in for the same scope - the uncapped 3% formula plus 50% plan review surcharge produces the largest absolute permit cost in the DMV.
Calculate Your Fairfax Alteration Permit
The PermitPrice fee calculator supports Fairfax's alteration formula directly. Pick "Fairfax County, VA" and "Alteration" (or "Kitchen Remodel" / "Bathroom Remodel" - same fee structure) in the calculator dropdowns; enter declared construction value; the calculator returns building permit + plan review + 2% levy = all-in. The formula is straightforward to compute manually: multiply declared value by 4.59% (the effective combined rate of 3% BP + 50% PR + 2% levy on the BP+PR subtotal). For a $30,000 alteration: $30,000 x 0.0459 = $1,377. Add trade permits separately at Fairfax's tier tables. Use the worked examples on this page as a budgeting reference and confirm with Fairfax LDS at (703) 222-0801 before filing.
Fairfax alteration rule of thumb: declared value x 4.59% = all-in building permit cost (uncapped). Minimum all-in is $110.16 at declared values under $2,400. Trade permits add separately: $341-$568 electrical, $227-$341 plumbing, $227-$341 mechanical, each with own 2% levy. Confirm with Fairfax LDS before filing.
Open the Permit Fee CalculatorTrade Permits for Alterations in Fairfax
Residential alterations with electrical, plumbing, or mechanical scope require SEPARATE trade permits in Fairfax County. The 3% + 50% PR + 2% levy building permit covers the building permit and plan review only - it does NOT include circuits, fixtures, gas lines, water lines, ductwork, or HVAC equipment installation. Each trade permit is filed separately and carries the 2% Virginia state levy.
Residential electrical permit tiers: 0-149 amp $341 (covers most kitchen remodel, bathroom remodel, basement finish, deck circuit work where existing service is sufficient); 150-399 amp $455 (covers service-meter upgrade or panel replacement scope, common on full gut renovations); 400-599 amp $568 (heavy-up service for very large homes, EV charging hubs, large workshop / pool / hot tub combined load). Each tier covers all electrical work on the permit, not per-circuit pricing.
Residential plumbing permit tiers: 1-5 fixture $227 (covers most kitchen remodels, bathroom remodels, half-bath additions); 6-15 fixture $341 (covers whole-home gut renovations, additions with multiple bathroom scope, kitchen + bath combined permits). Fixtures include sinks, toilets, tubs/showers, dishwashers, water heaters, washing machine connections.
Residential mechanical (HVAC) permit tiers: 1-zone $227 (single-zone air handler, minor duct extension, single-system replacement); 2-3 zone $341 (multi-zone systems, full HVAC replacement on whole-home renovations, addition of new heating/cooling zones). Each zone covers the air handler and associated ducts under the permit.
Fairfax Alteration Permit Cost vs Virginia Neighbors and DC
Fairfax is the most expensive verified DMV jurisdiction for residential alterations at typical scope. The 3% formula combined with the 50% plan review surcharge and the 2% state levy produces an effective rate of 4.59% on declared value, dramatically higher than the value-based jurisdictions in Hampton Roads and the Richmond MSA. The table below compares the all-in alteration permit cost across the verified DMV cluster at three typical residential declared values.
| Jurisdiction | Alteration Pricing Method | $15k bathroom | $30k kitchen | $100k gut |
|---|---|---|---|---|
| Fairfax County | 3% of value + 50% PR + 2% levy | $688.50 | $1,377.00 | $4,590.00 |
| Washington, DC | $30 + 2% + 10% Enhanced + 0.13% GBF + Enhanced | $384.45 | $735.90 | $2,376.00 |
| Loudoun County | Bundled $395 flat + 2% levy | $402.90 | $402.90 | $402.90 (under 1,000 sq ft) |
| Virginia Beach | $50 + $5/$1k + $100 PR + $10 tech + 2% levy on BP | $237.50 | $314.00 | $671.00 |
| Henrico County | $100 + $6/$1,000 over $5,000 (cap $680) + 2% levy | $163.20 | $255.00 | $693.60 (cap) |
| Richmond City | $63 + $6.07/$1,000 over $2,000 + 2% levy | $144.75 | $237.62 | $670.41 |
| Norfolk City | Flat $100 + tiered PR ($35) + $15 + 2% levy on $100 | $152.00 | $152.00 | $152.00 |
All figures are building permit only - trade permits (electrical, plumbing, mechanical) excluded across all jurisdictions. Norfolk's flat $152 is structurally the cheapest at every alteration value because the residential alteration permit is value-independent. Henrico's $680 cap at $101,667 declared value freezes the all-in fee at $693.60 for any high-value alteration. Richmond's value formula is uncapped but at a 0.607% slope, much less aggressive than Fairfax's 3%. Loudoun's bundled flat fee applies to alterations under 1,000 sq ft. DC charges Tier 3 alterations at 2% rate + 10% Enhanced + 0.13% GBF (with own Enhanced). Fairfax's 3% + 50% PR + 2% levy = 4.59% effective rate is the structural reason Fairfax is the most expensive verified DMV jurisdiction. Chesterfield County is NOT in this table because Chesterfield's residential fee schedule does not include a verified general-alteration line item in PermitPrice's source data. Source-age caveats: Loudoun is July 2022; Norfolk is July 2021; Richmond is June 2022.
