Fairfax Pool Permit Cost (2026)

Swimming pool permit fees in Fairfax County, Virginia, pulled directly from the official Appendix Q Land Development Services Fee Schedule (FY2025, effective July 1, 2024). Fairfax uses flat-fee pricing for in-ground swimming pools: a $270 flat building permit, regardless of pool cost or pool size. Add the mandatory 50% plan review ($135) and Virginia's 2% state levy on the combined permit and plan review subtotal ($8.10), and an in-ground pool building permit totals $413.10 all-in. Pool barriers (the safety fence required by the Virginia Construction Code) are filed as a separate alteration permit when a new code-compliant fence is needed. Electrical and plumbing trade permits are also required for any pool with circulation equipment and are billed under their own tiered Fairfax schedules.

What This Guide Covers - and What It Does Not

This guide covers: Fairfax County, Virginia residential in-ground swimming pool building permit fees as published in the official Appendix Q Land Development Services Fee Schedule (FY2025, effective July 1, 2024). Coverage includes the $270 flat in-ground pool building permit, the 50% plan review ($135), Virginia's 2% state levy on the permit + plan review subtotal ($8.10), and the typical electrical and plumbing trade permits required for residential pool circulation, lighting, fill lines, and drains.

This guide does NOT cover: Above-ground pool permits (Appendix Q does not list above-ground swimming pools as a distinct flat-fee line item; consult Land Development Services for current treatment - they may fall under residential alteration or be exempt depending on depth and installation type). Commercial swimming pool permits (which fall under separate Appendix Q categories). Spa or hot tub permits filed without a pool. Zoning approvals required before permit submission (setback verification, lot coverage, RPA or floodplain overlays). Health Department fees or licensing for community or HOA pools. Right-of-way or driveway encroachment permits if construction access requires sidewalk closure. Landscape, irrigation, or stormwater permits triggered by pool installation. Costs from the pool installation contractor (excavation, shell, decking, equipment, labor).

Note on portable wading pools: The Virginia Construction Code (USBC) and the International Swimming Pool and Spa Code generally exempt portable wading pools designed to be drained and stored from building permit requirements. Anything semi-permanent, deeper than 24 inches, or with a circulation system requires a permit. Verify directly with Fairfax County Land Development Services at (703) 222-0801 before assuming exemption.

Note on pool barrier requirement: The Virginia Construction Code requires a barrier (fence, wall, or equivalent) around any residential pool with water depth greater than 24 inches. The Fairfax County Appendix Q schedule does not list a dedicated pool-barrier line item, so a new fence permit is filed as a residential alteration: 3% of declared fence cost, $72 minimum. A 6-foot privacy fence with self-closing self-latching gates around a typical residential lot at $5,000 declared cost runs $206.55 all-in ($150 permit + $75 plan review + $4.05 state levy = $229.05 if minimum applies; or use the $72 minimum scenario). If you already have a code-compliant yard fence, no additional barrier permit is needed - confirm with LDS before assuming.

Key Takeaways
  • Fairfax County uses flat-fee pricing for in-ground swimming pools: $270 regardless of declared pool value. This is structurally different from how Fairfax prices most other residential projects (decks, additions, kitchen remodels, basement finishes), which are billed at 3% of construction cost. The pool flat-fee carve-out is published in Appendix Q.
  • Plan review is 50% of the building permit fee ($135 for a pool), and Virginia's 2% state levy applies to the combined permit + plan review subtotal ($405 x 2% = $8.10). Total all-in for an in-ground pool is $413.10.
  • Construction value does not affect the Fairfax pool permit fee. A $20,000 fiberglass shell pool and a $90,000 custom gunite pool both cost $413.10 in city building permit fees. The number you write on the application changes only the contractor scope, not the permit math.
  • Pool barriers (the safety fence required by the Virginia Construction Code for any pool with water depth greater than 24 inches) are filed as a separate residential alteration permit when a new fence is required. Appendix Q does not list a dedicated pool-barrier flat fee, so the fence runs at 3% of declared fence value with a $72 minimum, plus 50% plan review and 2% levy.
  • Electrical and plumbing trade permits are required for any in-ground pool with circulation equipment and are billed under separate Fairfax tiered schedules. A standard 200-amp service for the pool sub-panel falls in the 150-399 amp tier at $378 + $7.56 state levy = $385.56. A 1-5 fixture plumbing permit (fill line, drain) is $340 + $6.80 = $346.80. Mechanical permits apply only if a gas pool heater is installed.
  • Fairfax's $413.10 in-ground pool permit is one of the cheapest among Northern Virginia jurisdictions because it is flat. Compare to Loudoun County (1% of value formula), Richmond City ($63 + $6.07/$1k value formula), and Chesterfield County (flat $108.14 - actually cheaper than Fairfax for pools). High-cost pool builds favor flat-fee jurisdictions; low-cost pool builds favor percentage formulas.
  • A $30,000 in-ground pool with new barrier and standard electrical and plumbing trade permits typically lands in the $1,150-$1,250 range all-in across all Fairfax permits. The pool building permit itself is the smallest line; trade permits and barrier alteration are the larger pieces. Budget for the full stack, not just the $413.10 pool line.
  • The Appendix Q PDF was downloaded directly from fairfaxcounty.gov/landdevelopment and verified March 15, 2026. Next verification is due July 15, 2026, when FY2026 rates may publish. Always verify current rates with Fairfax LDS at (703) 222-0801 before filing - rates change with each fiscal year.
Calculate Your Pool Permit All Fairfax Permit Fees

Fairfax Pool Permit Fee Components

Every Fairfax in-ground pool building permit is built from three components: the flat $270 building permit fee, the 50% plan review fee, and Virginia's 2% state levy applied to the combined subtotal. Pool barriers and trade permits are billed separately, each with their own component stack.

Component Amount How It Is Calculated
Building permit fee $270.00 Flat fee per Appendix Q. Does not vary with pool value or pool size.
Plan review $135.00 50% of building permit fee ($270 x 50%). Required on every pool permit.
2% Virginia state levy $8.10 2% of $405 subtotal (permit + plan review). Statutory under Code of Virginia §36-139 / USBC 107.2.
All-in in-ground pool permit total $413.10 $270 + $135 + $8.10. The fee any in-ground pool pays in Fairfax County, regardless of declared value.

Source: Fairfax County Appendix Q Land Development Services Fee Schedule, FY2025, effective July 1, 2024 - swimming_pool_inground line ($270 flat), plan review at 50%, and Virginia §36-139 state levy at 2% of subtotal. Verified March 15, 2026.

Worked Examples - Real Pool Projects in Fairfax County

Each example shows arithmetic from the same Fairfax fee schedule. Because Appendix Q lists in-ground pools as a flat fee, the building permit math is identical across pool values - the differences come from optional add-ons (barrier permit, electrical, plumbing).

Example 1: $30,000 in-ground pool, building permit only (existing code-compliant fence)

A homeowner installs a 16 x 32 fiberglass in-ground pool. Their back yard already has a 6-foot privacy fence with self-closing self-latching gates that meets the Virginia Construction Code barrier requirements, so no separate fence permit is required. They will pull electrical and plumbing trade permits separately through their installer.

  • Building permit fee (flat): $270.00
  • Plan review (50% of $270): $135.00
  • 2% Virginia state levy on $405 subtotal: $8.10
  • Total in-ground pool building permit: $413.10

Note: the construction value ($30,000 in this scenario) does not affect the Fairfax in-ground pool building permit fee. The same $413.10 applies whether the pool is declared at $20,000 or $80,000 - Appendix Q lists the swimming_pool_inground line as a flat fee. Trade permits and any new fence permit are billed separately.

Example 2: $50,000 in-ground pool with new pool barrier (no existing fence)

A homeowner installs a 18 x 36 gunite in-ground pool with declared construction cost of $50,000. The yard has no existing fence, so a new code-compliant pool barrier is required. The barrier is a wood privacy fence with self-closing gates, declared at $5,000.

In-ground pool building permit:

  • Building permit fee: $270.00 flat
  • Plan review (50%): $135.00
  • 2% Virginia state levy on $405: $8.10
  • Subtotal: $413.10

Pool barrier (residential alteration permit, $5,000 declared fence cost):

  • Building permit fee: max($5,000 x 3%, $72 min) = $150.00
  • Plan review (50% of $150): $75.00
  • 2% Virginia state levy on $225: $4.50
  • Subtotal: $229.50

Combined building permit total: $642.60 - not including electrical and plumbing trade permits.

Note: pool barrier fence is filed as a residential alteration in Fairfax because Appendix Q does not list a dedicated pool-barrier line. The 3% of value formula applies to the fence cost, not the pool cost. If the fence is declared at $2,000 or below, the $72 minimum applies and the barrier permit subtotal drops to $108 + $54 + $3.24 = $165.24.

Example 3: $30,000 in-ground pool with electrical and plumbing trade permits (existing fence)

The same $30,000 in-ground pool from Example 1, this time itemizing the typical trade permits a residential pool requires. Trade permit costs depend on actual installer scope; this example uses the standard tiers from Fairfax's published Appendix Q electrical and plumbing schedules.

In-ground pool building permit (from Example 1): $413.10

Electrical permit (200-amp service for pool sub-panel, 150-399 amp tier):

  • Trade permit fee: $378.00
  • 2% Virginia state levy on $378: $7.56
  • Subtotal: $385.56

Plumbing permit (1-5 fixtures - pool fill line and main drain):

  • Trade permit fee: $340.00
  • 2% Virginia state levy on $340: $6.80
  • Subtotal: $346.80

Combined permit total (estimate): $1,145.46

Estimate caveat: the electrical and plumbing trade permits use the published Appendix Q tier minimums for a typical pool scope. If the installer is wiring multiple new circuits beyond the sub-panel (separate circuits for pool pump, salt cell, heater, and pool lighting), each circuit may push the electrical permit into a higher tier. If pool plumbing requires more than 5 fixtures (fill, main drain, skimmers, equalizers, return jets), the plumbing permit moves into the 6-15 fixture tier ($466). Treat the trade permit subtotals here as floor estimates from the Appendix Q schedules; your installer's permit application is the source of truth.

Calculate Your Fairfax Pool Permit

The PermitPrice fee calculator supports Fairfax in-ground pool, residential alteration (used for pool barrier fence permits), and several trade permit categories directly. Pick your project type and enter the construction value (used for the validation flow - the Fairfax pool fee itself is flat regardless of value), and the calculator returns the all-in permit cost broken down by component.

Calculator coverage for Fairfax pools: in-ground pool ($413.10 all-in), residential alteration formula (used for new fence/barrier permits), and trade permit tiers (electrical, plumbing, mechanical).

Open the Permit Fee Calculator

For a new pool barrier permit, run the calculator using the residential alteration formula with your declared fence cost. Trade permits (electrical pool grounding, plumbing fill/drain) are tiered by amperage and fixture count - your installer's permit application is the final source of truth.

Trade Permits Fairfax Requires for Pools

A residential in-ground pool installation almost always pulls additional electrical and plumbing trade permits beyond the building permit and any new fence permit. Fairfax bills these under separate Appendix Q tiered schedules with their own state levy. Your pool installer typically pulls these on your behalf, but the costs land on the homeowner.

Trade Permit Component Fairfax Fee When It Applies
Electrical (0-149 amp tier) $341 + 2% levy = $347.82 Used for smaller pool installations where existing service handles the pool sub-panel
Electrical (150-399 amp tier) $378 + 2% levy = $385.56 Standard residential pool service upgrade tier; covers most new in-ground pool installations
Electrical (400-599 amp tier) $429 + 2% levy = $437.58 Required for high-load pools with electric heat pumps, salt systems, and full LED lighting on dedicated service
Plumbing (1-5 fixtures tier) $340 + 2% levy = $346.80 Standard pool fill line + main drain combination; covers most installations
Plumbing (6-15 fixtures tier) $466 + 2% levy = $475.32 Triggered when pool plumbing includes multiple skimmers, equalizers, return jets counted as separate fixtures
Mechanical (1-zone tier, gas heater) $135 + 2% levy = $137.70 Only required if a gas-fired pool heater is installed. Heat pumps are electrical only.
Trade permit minimum $135.00 floor No trade permit can be issued below $135 base. The 2% state levy applies on top.

Fairfax Pool Permit Cost vs Other Verified Virginia Jurisdictions

Fairfax's $413.10 in-ground pool permit sits in the middle of the verified Virginia cluster. Flat-fee jurisdictions (Fairfax, Chesterfield, Norfolk) decouple permit cost from pool value entirely; formula-based jurisdictions (Henrico, Richmond, Virginia Beach) charge more for higher-cost pool builds. The same $30,000 in-ground pool runs anywhere from $108 in Chesterfield to $314 in Virginia Beach across these jurisdictions - and Fairfax's flat $413.10 stays the same whether the pool is declared at $30,000 or $90,000.

Jurisdiction In-Ground Pool Formula $30,000 Pool All-In
Fairfax County $270 flat + 50% plan review + 2% levy $413.10
Chesterfield County $106.02 flat + 2% levy $108.14
Norfolk City $125 flat + $50 plan review + $15 + 2% levy $192.50
Henrico County $100 + $6/$1k over $5k (capped $680) $255.00
Virginia Beach City $50 + $5/$1,000 alteration formula $314.00
Richmond City $63 + $6.07/$1k over $2k (no cap) $237.62

All-in totals include the building permit fee, plan review (where bundled or separate), jurisdiction processing/technology fees, and the 2% Virginia state levy. Trade permits (electrical, plumbing) are excluded from these totals because they vary by installer scope. Fairfax flat $270 reflects the swimming_pool_inground line in Appendix Q FY2025; Chesterfield, Henrico, Richmond, Virginia Beach, and Norfolk use the verified formulas in their respective source.json files.

Frequently Asked Questions

A Fairfax County in-ground swimming pool building permit costs $413.10 all-in: $270 flat building permit fee + $135 plan review (50%) + $8.10 Virginia state levy (2% of the $405 subtotal). The flat fee is published in Appendix Q FY2025 and does not vary with pool value or pool size. Pool barrier fence (if a new one is needed) is filed as a separate residential alteration permit at 3% of fence cost. Electrical and plumbing trade permits are required and priced separately under their own tiered Fairfax schedules. Budget roughly $1,000-$1,250 for the full pool permit stack with a typical 200-amp electrical service, 1-5 fixture plumbing, and a $5,000 declared fence cost.
Appendix Q lists the in-ground swimming pool line as a flat fee of $270, separate from how Fairfax prices most other residential projects. Decks, additions, kitchen remodels, basement finishes, and most alterations are billed at 3% of declared construction cost (with a $72 minimum). Pools, like a small set of other carve-outs, get a flat rate. The plan review at 50% and the 2% state levy still apply on top, but the underlying building permit fee itself does not move with the pool value. A $20,000 pool and an $80,000 pool both pay $413.10 for the in-ground pool building permit.
If a code-compliant fence is not already in place, yes. The Virginia Construction Code requires a barrier (fence, wall, or equivalent) around any residential pool with water depth greater than 24 inches. The Fairfax Appendix Q schedule does not list a dedicated pool-barrier flat fee, so the new fence is filed as a residential alteration permit at 3% of declared fence cost (with a $72 minimum), plus 50% plan review and 2% state levy. A typical $5,000 wood privacy fence with self-closing gates runs $229.50 all-in for the alteration permit. If your existing yard fence already meets pool barrier requirements (minimum height, self-closing self-latching gates, no climbable pool side), no additional permit is required - confirm with Fairfax LDS before assuming.
No. Fairfax handles electrical and plumbing trade permits as separate applications under their own tiered Appendix Q schedules. A standard pool sub-panel installation in the 150-399 amp tier is $378 + $7.56 state levy = $385.56. A 1-5 fixture plumbing permit (pool fill line and main drain count as separate fixtures) is $340 + $6.80 levy = $346.80. If a gas pool heater is installed, add a 1-zone mechanical permit at $135 + $2.70 = $137.70. Each trade permit has its own state levy and minimum fee. Heat pumps and electric pool heaters do not require a separate mechanical permit because they are wired through the electrical permit instead.
The Fairfax Appendix Q FY2025 schedule's swimming_pool_inground line is the only flat-fee swimming pool line PermitPrice has verified. Above-ground pools, spas, and hot tubs are not listed as separate flat-fee categories in the version of Appendix Q we extracted on March 15, 2026. In practice, Fairfax LDS typically routes above-ground pools and spas through the residential alteration formula (3% of declared cost, $72 minimum), but the project type guardrail in PermitPrice doctrine prevents us from publishing that fee as verified without an explicit Appendix Q line. Confirm directly with Fairfax LDS at (703) 222-0801 before filing for an above-ground pool, spa, or hot tub - they will tell you which permit type and which fee category applies.
Fairfax County does not publish a guaranteed turnaround for residential pool permits, but a complete residential pool application submitted through the PLUS (Planning and Land Use System) portal at plus.fairfaxcounty.gov typically receives plan review feedback within 2-4 weeks during normal volume, longer during peak summer permit season. The complete application package is the residential building permit application, a site plan showing pool location and setbacks, the manufacturer's specification sheet for the pool shell and equipment, the barrier specification (if a new fence is required), the electrical and plumbing trade permit applications filed in parallel, and the soils or stormwater documentation triggered by the pool excavation. Call (703) 222-0801 or check the PLUS portal status before assuming a timeline.
The cross-jurisdiction differences come from each schedule's structure, not from any quality difference in the inspection scope. Chesterfield ($108.14 all-in for any pool), Norfolk ($192.50 in-ground / $116 above-ground), and Fairfax ($413.10 in-ground) all use flat fees that decouple pool value from permit fee. Henrico ($100 + $6/$1k over $5k, capped at $680), Richmond ($63 + $6.07/$1k over $2k, no cap), and Virginia Beach ($50 + $5/$1k value formula) use percentage formulas that scale with pool cost. For low-cost pools (under $20,000), the percentage-formula jurisdictions are usually cheaper. For high-cost pools (over $50,000), the flat-fee jurisdictions usually win because their permit fee does not move with the pool price. Fairfax's $413.10 is on the high end of the flat-fee group, but flat enough that a $90,000 luxury pool still pays $413.10 - which is dramatically less than the same pool would cost under Fairfax's standard 3% alteration formula ($2,754 + plan review + levy = $4,212). The flat-fee carve-out is a structural advantage for high-end pools.
No. The $413.10 Fairfax in-ground pool building permit fee is the county building permit cost only - the cost to apply, get plan review, and have inspections performed. It does not include any pool contractor work. A 16 x 32 fiberglass in-ground pool installed in the Northern Virginia market typically runs $55,000-$95,000 for the contractor scope (excavation, shell, decking, equipment, labor). A custom gunite pool with hardscape, lighting, and salt system runs $100,000-$200,000+. The permit fee is one of the smallest line items in your overall pool project budget; the bulk is contractor scope. PermitPrice tracks only the city/county permit fee component.

Actual permit fees are determined by Fairfax County Land Development Services at the time of application. Trade permit subtotals in this guide use the published Appendix Q tiers for typical residential pool scope; actual electrical and plumbing permit costs depend on installer scope and may run higher. Pool barrier requirements vary based on existing yard fence compliance with the Virginia Construction Code; verify directly with LDS before assuming an existing fence meets pool barrier code. Above-ground pool, spa, and hot tub permit treatment is not a verified Appendix Q line item and should be confirmed with LDS before filing.
