Prince William County, VA Building Permit Fees (2026)
Actual residential building permit fee formula from the official Prince William County FY26 Building Development Division fee schedule, effective July 1, 2025. Verified against the published county document.
This page covers: The residential building permit fee in Prince William County (use groups R-3, R-4, R-5), including the minimum fee, the per-square-foot rate for new construction and additions, the flat fees for pools and demolition, and the deck/finished-basement rates. All dollar amounts shown as "all-in" already include the county's combined surcharge stack as printed in the official schedule's Total column.
This page does NOT cover: Trade permits (electrical, plumbing, mechanical, gas), which are issued separately with their own minimum fees; the separate plan review filing fee for new residential construction; Land Development fees (lot grading inspection, escrow, site modification); Fire Marshal's Office inspection fees; and impact, proffer, or development fees.
Note on surcharges: Prince William County's schedule lists a 2% Virginia USBC state levy plus a 14% technology surcharge and a 10% indirect costs surcharge "calculated against the base fee" (26% nominal). The schedule's own pre-computed Total column reflects an effective combined surcharge of about 25.5% (for example, an $85.45 base becomes a $107.24 total). This page uses the schedule's printed Total amounts rather than recomputing at the nominal 26%.
Most small residential permits in Prince William County hit the minimum fee of $107.24 - the $85.45 base permit fee plus the county's combined surcharge stack. A residential swimming pool is a flat $177.52, and a deck over 250 sq ft is $266.31. New residential construction and additions are charged $0.1536 per square foot of gross floor area (basement and garage included), subject to the minimum fee.
- The minimum residential building permit fee is $85.45 base, or $107.24 all-in once the county's combined surcharge stack is added.
- New construction and additions are $0.1224 per sq ft base ($0.1536 all-in) of gross floor area including basement and garage, with a minimum fee that governs most small jobs.
- Residential repairs and alterations (R-3/R-4/R-5) are a flat $85.45 base / $107.24 all-in regardless of construction value.
- A private residential swimming pool is a flat $141.46 base / $177.52 all-in; building demolition is the same flat $141.46 / $177.52.
- Trade permits (electrical, plumbing, mechanical, gas) and the new-construction plan review filing fee are separate. The schedule is the FY26 adopted version, effective July 1, 2025.

The "Base" column is the permit fee before surcharges; the "All-In Total" column is the schedule's printed total including the 2% USBC levy plus the 14% technology and 10% indirect-cost surcharges.

How Prince William County Calculates Building Permit Fees
| Step | What Happens | Prince William County Rule |
|---|---|---|
| 1. Classify the project | Determine whether the work is new construction/addition, a repair/alteration, or a listed flat-fee project (pool, demolition, deck). | New construction/additions use per-sq-ft; repairs/alterations are flat; pools and demolition are flat dollar amounts. |
| 2. Calculate the base fee | Apply the per-square-foot rate or the listed flat amount for the project type. | $0.1224/sq ft (new/additions) or $0.2445/sq ft (finished basement) on gross floor area, or the flat fee for the project type. |
| 3. Apply the minimum fee | If the calculated base is below the minimum, the minimum fee governs. | $85.45 base ($107.24 all-in) for small jobs; $212.21 base ($266.31 all-in) standard minimum for new dwellings, additions, and decks over 250 sq ft. |
| 4. Add the surcharge stack | The county adds the Virginia USBC levy plus its technology and indirect-cost surcharges. | 2% USBC levy + 14% technology + 10% indirect costs on the base fee. The schedule prints the resulting Total (effective ~25.5%). |
| 5. Add separate fees if applicable | New residential construction carries a separate plan review filing fee; trade work needs its own permits. | Plan review filing fee $111.07 base ($139.38 all-in) per dwelling unit; electrical/plumbing/mechanical/gas permits are separate. |
Worked Examples
Example 1: 300 sq ft Deck (over the 250 sq ft threshold)
| Fee Component | Rule Applied | Amount |
|---|---|---|
| Per-sq-ft check | 300 × $0.1224 = $36.72 base | Below minimum |
| Applicable minimum (deck > 250 sq ft) | Base permit fee | $212.21 |
| All-In Total (printed) | Base + 2% levy + 14% tech + 10% indirect | $266.31 |
Assumptions: Deck over 250 sq ft, charged at the standard minimum fee because the per-square-foot calculation ($36.72) is lower. All-In Total taken directly from the schedule's printed Total column. Does not include trade permits or any required zoning clearance. Source: PWC FY26 fee schedule, effective July 1, 2025.
Example 2: 800 sq ft Finished Basement
| Fee Component | Rule Applied | Amount |
|---|---|---|
| Base Permit Fee | 800 sq ft × $0.2445 | $195.60 |
| Minimum-fee check | $195.60 vs $85.45 minimum | Per-sq-ft governs |
| All-In Total | 800 sq ft × $0.3069 (printed total rate) | $245.52 |
Assumptions: 800 sq ft of finished basement area. Base computed at $0.2445/sq ft; All-In Total computed at the schedule's printed combined rate of $0.3069/sq ft. Electrical, plumbing, and mechanical work for the basement require separate trade permits not included here. Source: PWC FY26 fee schedule, effective July 1, 2025.
Practitioner Insight
Prince William County's per-square-foot building fee is low enough that the minimum fee governs most ordinary residential jobs. At $0.1224 per square foot, a project has to exceed roughly 1,735 square feet of gross floor area before the calculated fee passes the $212.21 standard minimum - so a typical deck, shed, or modest addition lands at the minimum. That makes the surcharge stack, not the square-foot rate, the part of the bill worth understanding.
The schedule lists three surcharges (2% state levy, 14% technology, 10% indirect costs) "calculated against the base fee," which reads as 26%. In practice the county's printed Total column works out to about 25.5% - an $85.45 base becomes $107.24, not $107.66. The difference is small, but if you reproduce the math yourself you should use the schedule's printed totals rather than your own 26% sum. And remember decks must be permitted separately from the house on new construction, so a new-build deck is its own line, not part of the dwelling's per-square-foot fee.

When This Estimate May Not Apply
Trade permits are charged separately
A finished basement, addition, or kitchen project usually needs electrical, plumbing, and/or mechanical permits, each with its own minimum fee ($107.24 all-in residential). The building permit fee on this page does not include them.
New residential construction adds a plan review filing fee
New dwellings carry a separate plan review filing fee of $111.07 base ($139.38 all-in) per dwelling unit, in addition to the building permit fee. Additions and alterations are generally not subject to this filing fee.
Land Development and impact fees are separate
Lot grading inspection, escrow, site modification, Fire Marshal inspection fees, and any proffer or impact fees are collected separately by other county divisions and can exceed the building permit fee on larger projects.
Surcharge percentages are reset annually
The 14% technology and 10% indirect-cost surcharges are noted as subject to change each year based on the approved budget. The FY26 schedule's printed totals are used here; a future budget could shift the all-in amounts.
Commercial or non-residential construction
This page covers residential R-3/R-4/R-5 permits only. Non-residential and R-1/R-2 work uses higher minimums (for example $177.52 all-in) and value-based rates. Do not apply these residential rates to commercial projects.
