Loudoun County Alteration Permit Cost (2026)

Residential alteration permit fees in Loudoun County, Virginia, pulled from the Loudoun County Building and Development residential fee schedule (effective July 1, 2022). Loudoun uses a bundled flat-fee structure for residential alterations under 1,000 sq ft: a single $395 flat fee that combines the building permit, the plan review, and the county zoning permit, plus the 2% Virginia state levy on the full bundled amount = $402.90 all-in regardless of declared construction value. The bundled-flat structure is unique among the verified DMV cluster - no other jurisdiction combines building permit, plan review, and zoning permit into a single line item. A $5,000 minor kitchen update, a $30,000 bathroom remodel, and a $50,000 small basement finish all cost the same $402.90 if the work area is under 1,000 sq ft. Above 1,000 sq ft, Loudoun switches to a 1%-of-construction-value formula plus a separate $335 plan review fee, plus the 2% Virginia state levy - this larger-scope path is NOT currently modeled in the PermitPrice calculator and is excluded from this guide's worked examples. The schedule is effective July 1, 2022 - source-age caveat disclosed on the page.

What This Guide Covers - and What It Does Not

This guide covers: Loudoun County residential 1-2 family alteration and repair permit fees under the residential_alteration_repair line item in PermitPrice's verified source.json. Coverage is limited to alteration scopes under 1,000 sq ft work area, which is the scope captured by Loudoun's bundled $395 flat-fee structure. The bundled fee includes the building permit, the plan review, and the county zoning permit in a single line item. The 2% Virginia USBC state levy is applied to the full bundled amount per the source.json's interpretation of the published schedule, producing $402.90 all-in. Loudoun is unique among verified VA jurisdictions in folding the zoning permit into the building permit bundle - other jurisdictions either don't have a separate zoning permit for residential alterations or charge it separately.

This guide does NOT cover: Alteration scopes over 1,000 sq ft work area - Loudoun switches to a 1%-of-construction-value building permit fee plus a separate $335 plan review fee plus the 2% state levy at that threshold. The over-1,000 sq ft path is not modeled in the PermitPrice calculator and is excluded from worked examples in this guide. Trade permit fees (electrical, plumbing, mechanical) for the alteration scope - Loudoun charges these separately; new residential construction (Loudoun uses a separate per-sq-ft formula); zoning special exception variances (the $395 bundle includes the standard zoning permit, not special exception applications); HOA architectural review (Loudoun has a significant HOA community network in places like Brambleton, Stone Ridge, and Lansdowne that may require separate HOA approval before the county permit); the cost of materials, labor, or construction itself; downstream property tax reassessment.

The structural advantage of Loudoun's bundled structure: Under 1,000 sq ft, Loudoun's $402.90 all-in is structurally cheaper than Fairfax County for any alteration over approximately $9,500 declared construction value (since Fairfax charges 3% + 50% PR + 2% levy = approximately 4.59% effective rate). The two adjacent NOVA jurisdictions sit on opposite ends of the pricing spectrum at typical residential scope: at $30,000 declared, Loudoun $402.90 vs Fairfax $1,377 = Loudoun saves $974.10. At $50,000 declared, Loudoun $402.90 vs Fairfax $2,295 = Loudoun saves $1,892.10. At $100,000 declared (still under 1,000 sq ft for some scopes like small basement finishes), Loudoun $402.90 vs Fairfax $4,590 = Loudoun saves $4,187.10. The bundled flat-fee structure is the structural reason.

The 1,000 sq ft threshold is the critical decision point: Loudoun's published schedule has two structural tiers for residential alterations - under 1,000 sq ft work area uses the bundled $395, over 1,000 sq ft uses 1% of construction value + $335 PR + 2% levy. The threshold is by work area, not declared value. Whole-house renovations and full basement finishes typically exceed 1,000 sq ft and trigger the over-1,000 path. Single-room remodels (kitchens, bathrooms), single-floor partial finishes, and most one-time-room alterations stay under the 1,000 sq ft threshold and qualify for the bundled flat fee. Confirm work area calculation with Loudoun County Building and Development BEFORE filing if the scope is close to the 1,000 sq ft threshold - the over-1,000 path can produce dramatically higher fees on high-value renovations.

Key Takeaways
  • Loudoun County residential alteration permits use a bundled flat-fee structure: $395 combining the building permit, the plan review, and the county zoning permit into a single line item, plus the 2% Virginia state levy on the bundled amount = $402.90 all-in for any residential alteration under 1,000 sq ft work area regardless of declared construction value. The bundled-flat structure is unique among the verified DMV cluster.
  • The 1,000 sq ft threshold is the critical decision point. Under 1,000 sq ft work area: $402.90 all-in flat. Over 1,000 sq ft work area: 1% of construction value building permit + $335 separate plan review fee + 2% Virginia state levy = variable (much higher for high-value renovations). Single-room remodels (kitchen ~150-300 sq ft, bathroom ~50-100 sq ft) stay under the threshold. Whole-home renovations, full basement finishes over 1,000 sq ft, and large additions exceed the threshold.
  • The bundle includes the county zoning permit - this is the unique feature. Other VA jurisdictions either don't have a separate zoning permit for residential alterations (Fairfax) or charge it separately from the building permit (Henrico). Loudoun folds the zoning permit into the $395 bundle, saving the applicant a separate filing and reducing administrative friction. The standard zoning permit covers most residential scopes - special exception variances, setback variances, and use changes still require separate zoning applications outside the bundle.
  • Loudoun is structurally cheaper than Fairfax County for any alteration over approximately $9,500 declared value. The two adjacent NOVA jurisdictions are dramatically different at typical residential scope: at $30,000 declared, Loudoun saves $974.10 vs Fairfax; at $100,000 declared (if under 1,000 sq ft), Loudoun saves $4,187.10. The bundled flat structure is the structural reason. For mid-to-high-value alteration scope inside the 1,000 sq ft work area threshold, Loudoun is the cheapest DMV jurisdiction.
  • Loudoun has an active HOA community network in places like Brambleton, Stone Ridge, Lansdowne, and Ashburn. HOA architectural review may be required BEFORE the Loudoun County permit application. HOA architectural review fees and timeline are separate from county permit fees and can add $50-$500 and 2-6 weeks to project timeline. Confirm HOA requirements with your HOA board before relying solely on the county permit timeline.
  • Compared to other VA jurisdictions at $30,000 declared value with work area under 1,000 sq ft: Loudoun $402.90, Norfolk City $152.00, Richmond City $237.62, Henrico County $255.00, Virginia Beach $314.00, DC $735.90, Fairfax County $1,377.00. Loudoun is mid-to-high in the DMV cluster at low declared values (the $395 bundled floor is higher than the value-based formulas at low declared values), but Loudoun is structurally cheaper than Fairfax at every declared value over approximately $9,500.
  • Trade permits (electrical, plumbing, mechanical) for alterations are filed SEPARATELY in Loudoun. The $395 bundled fee does NOT include trade permits - it includes only the building permit, plan review, and county zoning permit. Loudoun's trade permit fees are not fully modeled in PermitPrice's source.json - confirm trade permit costs with Loudoun County Building and Development before relying on the $402.90 figure as a complete budget. Typical trade permit add-ons may range $50-$300 depending on scope.
  • For projects that include structural changes (load-bearing wall removal, beam installation, footing modifications), Loudoun may require stamped structural drawings prepared by a Virginia-licensed structural engineer. The engineering review and stamping costs are NOT included in the $395 bundled plan review - those are billed by the engineer separately ($1,500-$5,000 typical for residential structural work). Confirm structural review requirements with Loudoun County Building and Development before relying on the $402.90 figure for any alteration involving load-bearing modifications.
  • Source-age caveat - the Loudoun County residential fee schedule is effective July 1, 2022 - approximately four years old at last verification. This is the most recent published schedule version PermitPrice has located. The bundled $395 fee for under-1,000 sq ft scopes is stable from the 2022 adoption. Loudoun has not posted a more recent revision that PermitPrice has located. Always verify current fees with Loudoun County Building and Development before filing a load-bearing budget. Source.json confidence: medium with explicit source-age caveat.

Loudoun Alteration Permit Fee Components

Loudoun's bundled $395 flat fee covers three components in a single line item: the building permit, the plan review, and the county zoning permit. The 2% Virginia state levy is applied to the bundled amount on top. The breakdown below shows the implicit component math under the bundle (the actual fee charged is the $395 + $7.90 levy = $402.90 all-in - the line-item breakdown is illustrative only). For scopes over 1,000 sq ft, Loudoun switches to a separate-line-item structure (1% BP + $335 PR + 2% levy on BP) - this path is excluded from the table below.

Component Under 1,000 sq ft (bundled) $30k under 1,000 sq ft $50k under 1,000 sq ft $100k under 1,000 sq ft
Bundled flat fee ($395) $395.00 $395.00 $395.00 $395.00

2% Virginia state levy (on $395) $7.90 $7.90 $7.90 $7.90
All-in alteration permit total $402.90 $402.90 $402.90 $402.90

Source: Loudoun County Building and Development residential fee schedule effective July 1, 2022. The bundled $395 fee combines the building permit, the plan review, and the county zoning permit into a single line item for residential alterations under 1,000 sq ft work area. The 2% Virginia state levy is applied to the full bundled amount per Code of Virginia Section 36-139 and the source.json's interpretation of the published schedule (per the source.json description: "Loudoun's flat $395 fee already bundles plan review and zoning permit; the levy is applied to the full bundled amount as a conservative estimate"). The bundled fee does NOT include trade permits (electrical, plumbing, mechanical), HOA architectural review, special exception zoning applications, or stamped engineering drawings for structural changes. For scopes over 1,000 sq ft work area, Loudoun switches to a separate-line-item structure: 1% of construction value building permit + $335 separate plan review fee + 2% Virginia state levy on the building permit subtotal. The over-1,000 sq ft path is not modeled in the PermitPrice calculator and is excluded from this table.

Worked Examples - Real Alteration Projects in Loudoun

The four worked examples below illustrate Loudoun's bundled flat-fee structure at a range of declared values, all within the under-1,000 sq ft work area threshold. Notice that the all-in fee does NOT change with declared construction value - the bundled $402.90 applies to any residential alteration under 1,000 sq ft. Trade permits are filed separately under Loudoun's trade permit schedule and are NOT included here - this is the bundled building+PR+zoning permit only.

Example 1: $15,000 full bathroom remodel (80 sq ft work area)

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, all new GFCI electrical, full plumbing rough-in for the new layout. Work area: 80 sq ft (typical full bath). Contractor invoice: $15,000.

  • Declared value: $15,000 (does not affect fee under 1,000 sq ft)
  • Work area: 80 sq ft (under 1,000 sq ft - bundled path)
  • Bundled flat fee (BP + PR + zoning): $395.00
  • 2% Virginia state levy (on bundled $395): $7.90
  • Building permit total: $402.90

Note: the bundled fee structure means a $15,000 bathroom in Loudoun ($402.90) is meaningfully more expensive than the same scope in Richmond City ($144.75) or Norfolk City ($152.00), but the same scope in Fairfax County costs $688.50 building permit only. Loudoun saves $285.60 vs Fairfax for the same scope. The bundled structure compounds savings at higher declared values - Loudoun beats Fairfax by over $4,000 at $100k declared value.

Example 2: $30,000 full kitchen remodel (200 sq ft work area)

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 to support new circuits, and minor plumbing relocation for the new sink. Work area: 200 sq ft (typical kitchen). Contractor invoice: $30,000.

  • Declared value: $30,000 (does not affect fee under 1,000 sq ft)
  • Work area: 200 sq ft (under 1,000 sq ft - bundled path)
  • Bundled flat fee (BP + PR + zoning): $395.00
  • 2% Virginia state levy (on bundled $395): $7.90
  • Building permit total: $402.90

Note: trade permits for the new electrical and plumbing scope would be filed separately. The same $30,000 kitchen remodel costs $1,377 building permit in Fairfax County (Loudoun saves $974.10), $735.90 in DC, $255 in Henrico County, $237.62 in Richmond City, and $152 in Norfolk City. Loudoun is mid-pack at this scope - cheaper than Fairfax and DC, more expensive than Richmond, Henrico, and Norfolk. The bundle includes the county zoning permit, which is a meaningful administrative savings in NOVA where zoning approvals can be slow.

Example 3: $50,000 partial basement finish (650 sq ft work area)

A homeowner files an alteration permit for a partial basement finish: one new bedroom (~150 sq ft), one new full bathroom (~80 sq ft), one new family room (~420 sq ft) - total work area 650 sq ft (under 1,000 sq ft). New egress window, new electrical circuits, new HVAC extension, new bathroom plumbing rough-in, new walls and flooring. Contractor invoice: $50,000.

  • Declared value: $50,000 (does not affect fee under 1,000 sq ft)
  • Work area: 650 sq ft (under 1,000 sq ft - bundled path)
  • Bundled flat fee (BP + PR + zoning): $395.00
  • 2% Virginia state levy (on bundled $395): $7.90
  • Building permit total: $402.90

Note: the same $50,000 partial basement finish costs $2,295 building permit in Fairfax County (Loudoun saves $1,892.10), $1,204.50 in DC, $377.40 in Henrico County, $361.45 in Richmond City, $416 in Virginia Beach, and $152 in Norfolk City. Loudoun is mid-pack at $50k declared. If the basement scope grew over 1,000 sq ft, Loudoun would switch to the 1% formula path: 1% of $50k = $500 BP + $335 PR + $10 levy = $845 - meaningfully more expensive. Stay under 1,000 sq ft to keep the bundled flat fee.

Example 4: $100,000 single-story kitchen + bathroom + family room remodel (950 sq ft work area)

A homeowner files an alteration permit for a coordinated single-story remodel touching the kitchen (250 sq ft), one bathroom (80 sq ft), and the family room (620 sq ft) - total work area 950 sq ft (under 1,000 sq ft). Full kitchen gut and rebuild with high-end appliances, full bathroom gut, new flooring throughout the connected family room, partial new electrical scope, partial new plumbing for kitchen sink relocation. Contractor invoice: $100,000.

  • Declared value: $100,000 (does not affect fee under 1,000 sq ft)
  • Work area: 950 sq ft (under 1,000 sq ft - bundled path)
  • Bundled flat fee (BP + PR + zoning): $395.00
  • 2% Virginia state levy (on bundled $395): $7.90
  • Building permit total: $402.90

Note: this is where Loudoun's bundled structure produces dramatic savings - $100,000 declared value but only $402.90 all-in. The same $100,000 renovation costs $4,590 building permit in Fairfax County (Loudoun saves $4,187.10 vs Fairfax), $2,376 in DC (Loudoun saves $1,973), $683.40 in Henrico County, $671.02 in Richmond City, and $671 in Virginia Beach. Loudoun is cheaper than all three value-based VA cities at this scope because of the bundled flat structure. Critical caveat: the work area is at 95% of the 1,000 sq ft threshold - any scope expansion beyond 1,000 sq ft would trigger the 1% formula path (1% of $100k = $1,000 BP + $335 PR + 2% levy on $1,000 = $1,355 vs $402.90). Confirm work area carefully BEFORE filing.

Calculate Your Loudoun Alteration Permit

The PermitPrice fee calculator supports Loudoun's bundled $395 alteration formula for under-1,000 sq ft work area. Pick "Loudoun County, VA" and "Alteration" in the calculator dropdowns. The calculator returns $402.90 all-in (bundled $395 + 2% Virginia state levy) regardless of declared construction value. For alteration scopes over 1,000 sq ft work area, the calculator does NOT currently support the 1% formula + $335 PR + 2% levy path - use the over-1,000 path manually: (1% of declared value) + $335 + 2% of (1% of declared value). Trade permits filed separately under Loudoun's trade schedule and are not modeled in this calculator.

Loudoun alteration rule of thumb: $402.90 all-in for any residential alteration under 1,000 sq ft work area, regardless of declared construction value. Over 1,000 sq ft: 1% of declared value + $335 PR + 2% levy = approximately 1.03% of declared + $335 floor. Trade permits filed separately under Loudoun's trade schedule. The bundled $395 fee includes building permit, plan review, AND county zoning permit - this is structurally unique.

Trade Permits for Alterations in Loudoun

Residential alterations with electrical, plumbing, or mechanical scope require SEPARATE trade permits in Loudoun. The $395 bundled fee includes ONLY the building permit, plan review, and county zoning permit - it does NOT include trade permits. The bundled fee covers the structural/architectural review of the alteration plus the zoning compliance check; it does NOT cover circuits, fixtures, gas lines, water lines, ductwork, or HVAC equipment installation.

How to get current trade permit fees: Loudoun's trade permit fees are not fully modeled in PermitPrice's source.json - confirm trade permit costs with Loudoun County Building and Development before budgeting. The county online application portal at loudoun.gov/bdapplyonline accepts trade permit applications and shows current fee rates at the application step. The Building and Development department main contact information is published at loudoun.gov/96/Building-Development.

Why trade permits are excluded from the bundle: Loudoun's bundle design captures the three permits that always go together for any residential alteration (building permit, plan review, county zoning permit). Trade permits are scope-specific - a kitchen remodel may need electrical and plumbing trade permits but no mechanical permit; a bathroom remodel may need plumbing only; a basement finish may need all three trades. The bundle does NOT include them because the bundle would have to span the maximum possible scope to be honest. Each trade permit is billed by Loudoun separately at the time of trade application, based on the specific scope of that trade.

Loudoun Alteration Permit Cost vs Neighbors

Loudoun's bundled $402.90 structure makes it expensive for very low declared values (a $1,000 minor repair costs $402.90 vs $64.26 in Richmond) but cheap for high-value renovations under the 1,000 sq ft threshold (a $100,000 renovation under 1,000 sq ft is $402.90 vs $4,590 in Fairfax). The table below compares the all-in alteration permit cost across the verified DMV cluster at four scopes, all under 1,000 sq ft work area.

Jurisdiction Pricing Method $15k bathroom $30k kitchen $50k partial basement $100k under 1,000 sq ft
Loudoun County Bundled $395 + 2% levy $402.90 $402.90 $402.90 $402.90
Norfolk City Flat $100 + $35 PR + $15 + 2% levy on $100 $152.00 $152.00 $152.00 $152.00
Richmond City $63 + $6.07/$1k over $2k + 2% levy $144.75 $237.62 $361.45 $671.02
Henrico County $100 + $6/$1k over $5k (cap $680) + 2% levy $163.20 $255.00 $377.40 $683.40
Virginia Beach $50 + $5/$1k + $100 PR + $10 tech + 2% on BP $237.50 $314.00 $416.00 $671.00
Washington, DC $30 + 2% + 10% Enhanced + 0.13% GBF + Enhanced $384.45 $735.90 $1,204.50 $2,376.00
Fairfax County 3% of value + 50% PR + 2% levy $688.50 $1,377.00 $2,295.00 $4,590.00

All figures are building permit only (or building+PR+zoning bundled for Loudoun) - trade permits (electrical, plumbing, mechanical) excluded. Loudoun's $402.90 stays constant across declared values under 1,000 sq ft - the structural advantage at high declared values. At low declared values (under $15,000), Loudoun is mid-to-high in the DMV cluster because of the $395 floor. The crossover where Loudoun becomes the cheapest VA jurisdiction is approximately $43,000 declared (vs Richmond and Henrico). Above the 1,000 sq ft work area threshold, Loudoun switches to a 1% formula + $335 PR + 2% levy path that produces dramatically higher fees - confirm work area BEFORE filing. Source-age caveats: Loudoun is July 2022; Norfolk is July 2021; Richmond is June 2022; Virginia Beach is July 2025 (most current). Chesterfield County not in table - no verified general-alteration line item in source data.

Frequently Asked Questions

Loudoun County Building and Development's bundled $395 fee for residential alterations under 1,000 sq ft work area combines the building permit, the plan review, and the county zoning permit into a single line item. The published rationale is administrative efficiency - bundling reduces the number of separate fee transactions and simplifies the application process for homeowners. The bundle covers the standard zoning compliance check that every alteration requires: lot coverage verification, setback compliance, use compliance with the underlying zoning district. The bundle does NOT cover special exception variances, setback variances, or use changes - those still require separate zoning applications and fees outside the bundle. The bundled structure is unique among verified DMV jurisdictions and is the structural reason Loudoun is cheaper than Fairfax County at typical residential alteration scope.
Loudoun's threshold is based on the alteration work area - the floor area touched by the project, not the declared construction value. Under 1,000 sq ft: bundled $395 + 2% levy = $402.90 all-in. Over 1,000 sq ft: 1% of construction value building permit + $335 separate plan review + 2% levy on the building permit subtotal. Single-room remodels (kitchen ~150-300 sq ft, bathroom ~50-100 sq ft) stay under the threshold. Whole-house renovations, full basement finishes that touch the entire basement, and large additions that exceed 1,000 sq ft trigger the over-1,000 path. The over-1,000 path can produce dramatically higher fees: at $50,000 declared, the over-1,000 path is $500 + $335 + $10 levy = $845 (vs $402.90 bundled). Confirm work area carefully BEFORE filing with Loudoun County Building and Development. The 1,000 sq ft threshold is the critical scoping decision.
Yes - Loudoun has an active HOA community network in master-planned communities like Brambleton, Stone Ridge, Lansdowne, Ashburn Farm, and Cascades. HOA architectural review may be required BEFORE the Loudoun County permit application can be filed. The HOA architectural review process is separate from county permits and is governed by the HOA's covenants, conditions, and restrictions (CC&Rs). HOA review fees typically range $50-$500 depending on community and project scope. HOA review timelines can add 2-6 weeks to project budgeting. Common HOA-reviewed items include exterior color changes, deck additions, fence changes, pool installations, and external structural modifications. Interior alterations may also require HOA review in some communities. Contact your HOA board or property management company BEFORE assuming the $402.90 county permit covers the entire approval process. The county does not require HOA approval for its own permit, but the HOA may sue for non-compliance if you proceed without HOA approval.
Per Code of Virginia Section 36-139 and USBC Section 107.2, the 2% state levy is required on Virginia building permits. Loudoun's bundled $395 fee combines the building permit, plan review, and county zoning permit. The source.json's interpretation of the published Loudoun schedule applies the 2% levy to the full $395 bundle as a conservative estimate: $395 x 2% = $7.90 levy, producing $402.90 all-in. The source.json notes that this is a conservative estimate - the levy may be applied only to the implicit building permit portion of the bundle if Loudoun's accounting separates the components. The conservative estimate ensures budgets are not under-shot. Confirm the exact levy base with Loudoun County Building and Development if the budget margin matters.
Yes - Loudoun's residential_alteration_repair line item is a catch-all that applies the same bundled $395 fee (under 1,000 sq ft work area) to kitchen remodels, bathroom remodels, basement finishes under 1,000 sq ft, interior renovations, and most home-improvement work on existing 1-2 family dwellings. The fee math does not distinguish between project types within the alteration category. A $30,000 kitchen remodel and a $30,000 small basement finish under 1,000 sq ft both cost the same $402.90 all-in. The 1,000 sq ft threshold is the only variable - full basement finishes that touch the entire basement (often over 1,000 sq ft) trigger the over-1,000 path and produce higher fees. Trade permits (electrical, plumbing, mechanical) are filed separately and depend on the specific scope.
Two structural reasons. First, Loudoun's bundled flat fee ($395 + 2% levy = $402.90) does not scale with declared construction value, while Fairfax County's 3% formula scales linearly. At low declared values, this is a wash or slightly favors Fairfax (a $5,000 minor update costs $229.50 in Fairfax vs $402.90 in Loudoun). At mid-to-high declared values, Loudoun is dramatically cheaper because the bundled fee stays flat. Second, Loudoun's bundle includes the county zoning permit which Fairfax charges separately or absorbs in a different process. The crossover point where Loudoun becomes cheaper than Fairfax is approximately $9,500 declared value (where Fairfax 3% + 50% PR + 2% levy = approximately $402.90). For any alteration over $9,500 declared and under 1,000 sq ft work area, Loudoun is cheaper than Fairfax. See the Fairfax vs Loudoun comparison page for the full breakdown.
Yes - Loudoun County Building and Development provides online permit application through the Loudoun BD Apply Online portal at loudoun.gov/bdapplyonline. The online portal supports residential alteration applications, plan submission, fee payment, and inspection scheduling. The portal also shows current fee rates at the application step, which is useful for verifying the bundled $395 fee is still in effect. Loudoun does not publish a separate counter-review process for small scopes - all alteration applications go through the standard online review path under the bundled $395 fee structure. Inspection scheduling is integrated with the permit application.
The fee schedule on loudoun.gov is the most recent published version as of April 5, 2026 - effective July 1, 2022 (FY2023). PermitPrice has confirmed no newer revision is posted on loudoun.gov. The bundled $395 fee for under-1,000 sq ft scopes and the 1% formula + $335 PR for over-1,000 sq ft scopes are stable from the 2022 adoption. The schedule remains in effect until a future revision is published. For load-bearing budgets, contact Loudoun County Building and Development through the loudoun.gov/96/Building-Development page to confirm current rates before filing. PermitPrice's source.json confidence rating of "medium" reflects the source-age caveat - the schedule is nearly four years old at last verification. The bundled flat-fee structure is unlikely to change without notice; the absolute dollar figures may have been adjusted in interim revisions not yet posted online.

Next Step

Calculate your specific Loudoun alteration permit cost or compare against neighbors.

Always verify current alteration permit fees, the 1,000 sq ft work area threshold determination, and trade permit costs directly with Loudoun County Building and Development before budgeting or filing. Contact Loudoun County Building and Development through the loudoun.gov/96/Building-Development page or the Loudoun BD Apply Online portal at loudoun.gov/bdapplyonline. Confirm whether your specific scope qualifies for the bundled $395 fee (under 1,000 sq ft) or triggers the over-1,000 sq ft path (1% formula + $335 PR + 2% levy). Check your HOA covenants for architectural review requirements that may apply BEFORE the county permit application. Structural alterations may require stamped engineering 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 Loudoun County Building and Development at the time of application. The bundled $395 flat fee (combining building permit, plan review, and county zoning permit), the 1,000 sq ft work area threshold, the over-1,000 sq ft 1%-of-construction-value formula plus $335 separate plan review, and the 2% Virginia state levy application rules are all sourced from the Loudoun County Building and Development residential fee schedule effective July 1, 2022 (FY2023). PermitPrice's source.json carries a confidence rating of "medium" with explicit source-age caveat - the published schedule is nearly four years old at last verification (April 5, 2026), and PermitPrice has not located a newer revision on loudoun.gov. The catch-all residential_alteration_repair line item covers kitchen remodels, bathroom remodels, basement finishes under 1,000 sq ft work area, interior renovations, and most home-improvement work on existing 1-2 family dwellings. Trade permit fees (electrical, plumbing, mechanical) are filed separately under Loudoun's trade permit schedule and are NOT included in the $402.90 bundled all-in figure - confirm trade permit cost with Loudoun County Building and Development before relying on the bundled fee as a complete budget. HOA architectural review may be required before the county permit application in master-planned communities like Brambleton, Stone Ridge, Lansdowne, Ashburn Farm, and Cascades - HOA fees and timelines are separate from county permit fees. Structural alterations (load-bearing wall removal, beam installation, footing modifications) may require stamped structural drawings prepared by a Virginia-licensed structural engineer - these engineering costs are billed by the engineer separately, not by Loudoun. The 2% Virginia state levy is applied to the full $395 bundle per the source.json's conservative interpretation; the actual levy base may be narrower if Loudoun's accounting separates the bundle components.
