Fairfax County Alteration Permit Cost (2026)

Residential alteration permit fees in Fairfax County, Virginia, pulled from the Fairfax County Land Development Services Appendix Q FY2027 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 estimated construction cost, with a minimum of $141.75 (Appendix Q FY2027, effective July 1, 2026). The 2% Virginia state levy and the 10% Fairfax County technology surcharge both apply to the permit fee. Minimum all-in alteration permit is $158.77 for any alteration at or below $4,725 of cost. A $5,000 minor kitchen update runs $168.00 all-in. A $15,000 bathroom remodel runs $504.00. A $30,000 kitchen remodel runs $1,008.00. A $50,000 whole-home update runs $1,680.00. A $100,000 full gut remodel runs $3,360.00. The 3% formula is uncapped, producing dramatically higher alteration permit fees than value-based jurisdictions outside DMV-NOVA.

What This Guide Covers - and What It Does Not

This guide covers: Fairfax County, Virginia residential alteration and repair permit fees under Appendix Q FY2027 of the Fairfax County Land Development Services fee schedule. Coverage includes the 3% of estimated construction cost formula applied to residential alterations and repairs (Appendix Q I-B(K)), the $141.75 minimum permit fee (I-A.1) that creates an all-in minimum of $158.77, the 2% Virginia USBC state levy (I-A.12), and the 10% Fairfax County technology surcharge (Appendix Q Part III), both applied to the permit fee. 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 (a residential alteration electrical permit covering up to 100 fixtures, circuits or pieces of equipment is the Level One base fee of $141.75, or $158.77 with the 2% levy and 10% technology surcharge); commercial alterations (similar 3% structure with different inspection processes); new construction or additions that extend the heated envelope (priced per square foot under Appendix Q I-B(A) Table 1 at $0.15 per sq ft for wood frame, not by percentage of cost); 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 + $120 levy + $600 technology surcharge = $6,720 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.

Key Takeaways
  • 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 2% Virginia state levy plus the 10% Fairfax technology surcharge apply to the permit fee, so the all-in cost is the permit fee x 1.12.
  • The minimum permit fee is $141.75, producing an all-in minimum of $158.77 for alterations at or below $4,725 of cost. Below the $4,725 threshold the permit pegs at $141.75 ($141.75 permit + $2.84 levy + $14.18 surcharge = $158.77). Above $4,725 the formula scales linearly at 3% of cost.
  • The 3% formula is uncapped. A $100,000 declared alteration runs $3,360 all-in. A $250,000 luxury whole-home gut renovation runs $8,400 all-in. A $500,000 estate-grade renovation runs $16,800 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 $1,008.00 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).
  • Fairfax charges no separate plan review fee on residential alterations; the filing fee paid at application is a deposit against the permit fee, not an added line. Peer jurisdictions handle plan review differently: Loudoun bundles it 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 uncapped 3% rate 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 building permit fee, and the 10% Fairfax County technology surcharge (Appendix Q Part III) is applied to the same permit fee. On a $30,000 kitchen remodel: permit $900 + 2% levy $18.00 + 10% surcharge $90.00. Total $1,008. 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 building permit fee is itself smaller.
  • Trade permits (electrical, plumbing, mechanical) for alterations are filed SEPARATELY in Fairfax. A residential alteration electrical permit covering up to 100 fixtures, circuits or pieces of equipment is the Level One base fee of $141.75; with the 2% levy ($2.84) and 10% technology surcharge ($14.18) it is $158.77. Plumbing and mechanical permits are subject to the same $141.75 minimum permit fee (Appendix Q I-A.1), so each starts at $158.77 all-in; confirm the fixture or equipment tier above that with LDS. A typical $30,000 kitchen remodel with an electrical permit and a plumbing permit adds at least $317.54 in trade permits on top of the $1,008 building permit, for a total all-in alteration project permit cost of approximately $1,325.54.
  • 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 permit 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% figure for budgeting.

Fairfax Alteration Permit Fee Components

Fairfax's residential alteration permit splits into three component lines: the 3% building permit, the 2% Virginia state levy, and the 10% Fairfax technology surcharge, the last two both applied to the permit fee. The breakdown below shows component math at five typical residential alteration scopes from the minimum $158.77 floor through a $100,000 full gut renovation.

Component $1,500 minor ($141.75 min) $5k kitchen update $15k bathroom $30k kitchen $50k whole-home
Building permit (3% of value) $141.75 min $150.00 $450.00 $900.00 $1,500.00
2% Virginia state levy $2.84 $3.00 $9.00 $18.00 $30.00
10% Fairfax technology surcharge $14.18 $15.00 $45.00 $90.00 $150.00
All-in alteration permit total $158.77 $168.00 $504.00 $1,008.00 $1,680.00

Source: Fairfax County Land Development Services Appendix Q FY2027 fee schedule, effective July 1, 2026 (I-B(K) residential repairs and alterations; I-A.1 minimum fee; I-A.12 levy; Part III technology surcharge). The minimum permit fee is $141.75; alterations at or below $4,725 of cost peg at $141.75 regardless of actual percentage math. The 2% Virginia state levy is required by Code of Virginia Section 36-139 and USBC Section 107.2; the 10% technology surcharge is a Fairfax County charge under Appendix Q Part III. Both apply to the permit fee. Half of the permit fee is due at application as a filing-fee deposit and is credited toward the permit fee at issuance (County Code 61-1-3(d)11); it is not an extra charge and is not refunded if the application expires. Trade permit fees 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 trade permit fee tables and add their own amounts (from $158.77 each) on top of the building permit.

Example 1: $5,000 minor kitchen update

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
  • 2% Virginia state levy: $3.00
  • 10% Fairfax technology surcharge: $15.00
  • Building permit total: $168.00

Note: trade permits for the plumbing rough-in (one fixture - the pot filler) and the electrical (new circuit, Level One residential alteration electrical permit $158.77 all-in) would be filed separately. At the $141.75 minimum permit fee each, trade permits add at least $317.54 on top of the $168.00, for an all-in of about $485.54 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 3% rate and the 10% technology surcharge.

Example 2: $15,000 full bathroom remodel

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
  • 2% Virginia state levy: $9.00
  • 10% Fairfax technology surcharge: $45.00
  • Building permit total: $504.00

Note: trade permits for the full plumbing scope (sink + toilet + tub/shower + exhaust vent) and the electrical (GFCI circuits + exhaust fan + lighting, Level One residential alteration electrical permit $158.77 all-in) would be filed separately. At the $141.75 minimum permit fee each, trade permits add at least $317.54 on top of the $504.00, for an all-in of about $821.54. 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 $504.00 is roughly 3.1x Henrico's all-in figure for the same scope.

Example 3: $30,000 full kitchen remodel

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
  • 2% Virginia state levy: $18.00
  • 10% Fairfax technology surcharge: $90.00
  • Building permit total: $1,008.00

Note: trade permits for the electrical (panel work + new circuits, Level One residential alteration electrical permit $158.77 all-in) and plumbing (new sink + dishwasher, from $158.77) would be filed separately. Trade permits add at least $317.54 on top of the $1,008, for an all-in of about $1,325.54 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 3% permit fee accounts for $900 of the $1,008 total and the technology surcharge for another $90.

Example 4: $100,000 full gut renovation

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
  • 2% Virginia state levy: $60.00
  • 10% Fairfax technology surcharge: $300.00
  • Building permit total: $3,360.00

Note: trade permits for the full scope (electrical + plumbing + mechanical, each from the $141.75 minimum permit fee, $158.77 all-in; a whole-home electrical scope above 100 fixtures, circuits or pieces of equipment moves past the Level One tier, so confirm with LDS) would be filed separately. Trade permits add at least $476.31 on top of the $3,360, for an all-in of at least $3,836.31 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 $3,360 is roughly 4.8x Henrico's $693.60 all-in for the same scope - the uncapped 3% formula plus 10% technology 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 permit + 2% levy + 10% technology surcharge = all-in. The formula is straightforward to compute manually: multiply cost by 3.36% (the effective combined rate of 3% x 1.12). For a $30,000 alteration: $30,000 x 0.0336 = $1,008. Add trade permits separately. 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 3.36% = all-in building permit cost (uncapped). Minimum all-in is $158.77 at costs of $4,725 or less. Trade permits add separately from $158.77 each (Level One residential alteration electrical permit $141.75 + 2% levy + 10% surcharge). Confirm with Fairfax LDS before filing.

Trade Permits for Alterations in Fairfax

Residential alterations with electrical, plumbing, or mechanical scope require SEPARATE trade permits in Fairfax County. The 3% + 2% levy + 10% surcharge 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 and the 10% technology surcharge.

Residential electrical permit: a residential alteration electrical permit covering up to 100 fixtures, circuits or pieces of equipment is the Level One base fee of $141.75 under Appendix Q FY2027. Add the 2% levy ($2.84) and the 10% technology surcharge ($14.18) for $158.77 all-in. This covers most kitchen remodel, bathroom remodel and basement-finish circuit work. Scopes above 100 items move to a higher tier; confirm with LDS.

Residential plumbing permit: subject to the $141.75 minimum permit fee for any permit (Appendix Q I-A.1), so $158.77 all-in at minimum. Fixtures include sinks, toilets, tubs/showers, dishwashers, water heaters, washing machine connections; confirm the fixture-count tier for larger scopes with LDS.

Residential mechanical (HVAC) permit: subject to the same $141.75 minimum permit fee, so $158.77 all-in at minimum for a single-system replacement or minor duct extension. Multi-zone or whole-home HVAC replacement may price above the minimum; confirm the equipment tier with LDS.

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 2% state levy and the 10% technology surcharge produces an effective rate of 3.36% on cost, 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 cost + 2% levy + 10% tech $504.00 $1,008.00 $3,360.00
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% + 2% levy + 10% technology surcharge = 3.36% 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.

Frequently Asked Questions

Fairfax's 3% of declared value formula is structurally aggressive. Combined with the 2% Virginia state levy and the 10% Fairfax technology surcharge, the effective combined rate is 3.36% of construction cost. Most Virginia jurisdictions outside DMV-NOVA use much lower slopes: Henrico's residential alteration rate is $6 per $1,000 over $5,000 = 0.6% slope (with a $680 cap); Richmond's rate is $6.07 per $1,000 over $2,000 = 0.607% slope (uncapped); Virginia Beach's rate is $5 per $1,000 = 0.5% slope. Fairfax's 3% slope is roughly 5x the typical Virginia residential alteration rate. The structural reason: Fairfax operates a high-cost building department with extensive inspection, structural engineering review, and zoning compliance capacity to serve the densest Northern Virginia residential market - the fee structure funds that capacity.
The residential_alteration_repair line item in Appendix Q FY2027 catches kitchen remodels, bathroom remodels, basement finishes, interior renovations, exterior repair work that does not extend the heated envelope, partial demolition of interior elements, window and door replacements that change the rough opening, and most home-improvement permit categories that fall short of being a new addition. The Appendix Q kitchen_remodel line uses the same 3% rate. Work that extends the heated envelope (mudrooms, sunrooms, family-room extensions) is priced under new_construction_residential, a separate category - the rate is also 3% but with different inspection scope. Confirm classification at intake if your scope blurs the line (rear-wall removal with minor bump-out, conversion of an unfinished attic to heated living space, basement walk-out with new exterior egress).
Yes, declared value directly drives the 3% formula - so a lower declared value produces a lower permit fee. BUT Fairfax uses the rule "applicant-stated OR ICC Building Valuation Data (BVD), whichever greater" per Appendix Q valuation rules. The inspector compares your stated declared value against the ICC BVD standard for the alteration scope (square footage and finish-grade based). The greater of the two governs. Under-declaring an honest $30,000 kitchen remodel as $15,000 will trigger BVD comparison; if BVD lands at $24,000 for that scope, the BVD figure is used and the permit is recalculated. Beyond the BVD floor, under-declaration also risks administrative complications, re-inspection delays, and downstream property assessment disputes. Declare honestly. Stating a real $30,000 invoice as $30,000 produces $1,008 in permit fees; stating it as $20,000 to save $504 is rarely worth the BVD-trigger risk.
No. Plan review is covered by the 3% building permit fee. What Fairfax does require is a filing fee at application equal to half the permit fee; that payment is a deposit that is credited toward the permit fee when the permit is issued, so it does not raise the all-in cost. It is forfeited only if the application expires without a permit being issued. The only structural way to reduce the permit cost is to declare honestly and minimize scope (fewer wall removals, fewer trade scopes, less complex floor plan changes all reduce the 3% rate base). Henrico County and Richmond City also do not charge separate residential plan review, but their base formulas are far lower.
Separate. The 3% + 2% levy + 10% surcharge figure covers the building permit and plan review for the structural/architectural review only. Electrical, plumbing, and mechanical work require separate trade permits. A residential alteration electrical permit covering up to 100 fixtures, circuits or pieces of equipment is the Level One base fee of $141.75; plumbing and mechanical permits are subject to the same $141.75 minimum permit fee. Each trade permit carries the 2% Virginia state levy and the 10% technology surcharge, so each is $158.77 at minimum. A typical $30,000 kitchen remodel with electrical (new circuits + panel work) + plumbing trade permits adds at least $317.54 on top of the $1,008 building permit. Total all-in: approximately $1,325.54 for the kitchen remodel.
This guide covers residential alterations only. Appendix Q FY2027 includes commercial line items for tenant fit-out, commercial remodel, and commercial alteration with a similar value-based structure but different rate tiers and inspection scope. Confirm commercial alteration pricing with Fairfax Land Development Services directly - the rates and plan review structure differ from the residential 3% formula. The 2% Virginia state levy applies to commercial building permit fees on the same statutory basis as residential.
Load-bearing wall removal, beam installation, footing modifications, and other structural changes are still classified as residential alterations under Appendix Q. The 3% + 2% levy + 10% surcharge formula applies. HOWEVER, Fairfax may require additional engineering review and stamped structural drawings prepared by a Virginia-licensed structural engineer. The engineering review and stamping costs are NOT included in the standard plan review fee - those are billed by the engineer separately ($1,500 to $5,000 typical for residential structural work). Fairfax may also impose additional Land Development Services hourly review charges for complex structural review beyond the standard plan review scope. Confirm structural review requirements with Fairfax LDS at (703) 222-0801 before budgeting any alteration that involves load-bearing modifications.
Fairfax's residential alteration permit fees are formula-driven under Appendix Q and are not generally negotiable. The 3% rate, 2% levy, and 10% technology surcharge are fixed by published schedule. The declared construction value is the only variable input - and that must be honest per the BVD comparison rule. If a fee calculation appears incorrect, contact Fairfax Land Development Services at (703) 222-0801 to request a fee review. Fee reductions are rare; permit refund requests are handled under Appendix Q refund rules (typically 80% of permit fee refunded if permit is canceled before any inspection occurs, declining with each inspection completed). Disputes over declared value classification or scope classification can be appealed through LDS administrative review.

Call Fairfax LDS at (703) 222-0801 to confirm the 3% formula, the 10% technology surcharge, and the trade permit amounts for your specific alteration scope. Structural alterations may require additional engineering review and stamped drawings outside the standard plan review fee.
Disclaimer: All fee information on PermitPrice is for informational purposes only and is not an official permit quotation. Actual permit fees are determined by Fairfax County Land Development Services at the time of application. The 3% of estimated construction cost formula, the $141.75 minimum permit fee, the 2% levy, the 10% technology surcharge, the residential trade permit amounts, and the ICC Building Valuation Data comparison rule are all sourced from Appendix Q FY2027 (effective July 1, 2026 through June 30, 2027) as captured in PermitPrice's verified source.json for Fairfax County. Trade permit fees (electrical, plumbing, mechanical) are filed separately and are summarized in this guide; each trade permit also carries the 2% Virginia state levy and the 10% technology surcharge. Structural alterations (load-bearing wall removal, beam installation, footing modifications) may require additional engineering review and stamped drawings not included in the standard permit fee. Special exception permits, variance applications, and HOA architectural review processes are NOT covered by the 3% formula and are filed and paid separately. Confirm scope, classification, and current pricing with Fairfax LDS before budgeting.
