Virginia Retaining Wall Permit Cost (2026)

Retaining Wall Permit Cost by Jurisdiction ($10,000 Declared Wall)

The table below shows the all-in retaining wall permit cost for a $10,000 declared wall across the verified jurisdictions that publish a discrete retaining-wall line item, plus Washington, DC. A $10,000 declared wall is used as the common reference value because round thousands avoid the rounding ambiguity in DC's per-$1,000 rate. All Virginia figures include the 2% Virginia state levy. Actual permit fees depend on the declared construction value you submit with your application.

At a $10,000 declared wall the all-in permit cost spans roughly 4.4x - from Chesterfield's flat $116.28 to Washington, DC's $506.00. Chesterfield's flat fee does not scale: it is $116.28 whether the wall is small or large, low or tall. Fairfax ($459.00) and DC ($506.00) both scale with declared construction value, so the gap widens as wall value rises and narrows as it falls. All figures are all-in permit costs (building permit plus applicable plan review, surcharge, and levy) - they do not include the contractor's cost to build the wall. DC is a regional reference only, not a Virginia jurisdiction. Only Chesterfield and Fairfax publish a discrete retaining-wall line item among verified Virginia jurisdictions.

Verified Virginia Jurisdictions Without a Discrete Retaining-Wall Fee

Not every verified Virginia jurisdiction publishes a separate retaining-wall line item. The following jurisdictions do not, so this guide does not assign them a retaining-wall figure. Presenting a fabricated number for any of them would be dishonest. In each of these jurisdictions a retaining wall is typically permitted under the general accessory-structure or new-construction/alteration formula, or may require the building department to confirm the applicable line item for your specific scope. Verify the applicable fee directly with the relevant building department rather than relying on a single statewide number.

The Pricing Approaches Explained

The verified jurisdictions that publish a discrete retaining-wall fee use structurally different approaches. Understanding which approach applies helps you predict the all-in cost before your contractor starts the wall.

Approach 1: Flat fee that does not scale (Chesterfield County)

Chesterfield County's Residential Fee Schedule (FY2025-2026, effective July 1, 2025) groups retaining walls with decks, carports, gazebos, dormers, and boat docks under a single flat building-permit line item: $114. Adding the 2% Virginia state levy ($2.28) produces an all-in of $116.28 - regardless of the wall's declared value, size, or height. A short $3,000 wall and a large $20,000 wall both cost $116.28 in Chesterfield. A separate $50 Environmental Engineering site-inspection fee may apply to footprint-changing work, but retaining walls are not on Chesterfield's explicit mandatory-EE list; if it applies, the total would be $166.28. For the full Chesterfield breakdown, see the Chesterfield retaining wall permit guide.

Approach 2: Percentage of declared value (Fairfax County)

Fairfax County applies its standard declared-value formula to a retaining wall: 3% of declared construction value as the building permit fee ($72 minimum), plus 50% of the building permit as a plan review fee, plus 2% Virginia state levy on the combined building permit + plan review subtotal. The combined multiplier is the building permit x 1.53, with a floor of $110.16 below $2,400 declared value. The formula is uncapped, so a larger or more expensive wall produces a proportionally higher fee. At $10,000 declared: $300 BP + $150 PR + $9.00 levy = $459.00 all-in. At $20,000 declared: $600 x 1.53 = $918.00. Fairfax requires a permit only when the wall exceeds 4 feet (bottom of footing to top of wall); walls 4 ft and under are exempt, and walls over 8 ft must be designed by an engineer at separate cost. For the full Fairfax breakdown, see the Fairfax retaining wall permit guide.

Approach 3: Per-$1,000 of cost plus surcharge (Washington, DC - regional reference)

Washington, DC's Department of Buildings (DOB) bills a retaining wall at $46 per $1,000 of construction cost plus a 10% Enhanced Fee. There is no Green Building Fee on this line item and no Virginia state levy (DC is not a Virginia jurisdiction). At $10,000 declared: 10 x $46 = $460 + 10% = $506.00 all-in. The rate scales linearly with declared value, so it behaves similarly to Fairfax's percentage approach. A retaining wall in the public right-of-way also requires a separate DDOT permit not included in this DOB figure. For the full DC breakdown, see the Washington, DC retaining wall permit guide.

Common element: 2% Virginia state levy (both VA jurisdictions)

Both verified Virginia jurisdictions apply the 2% Virginia state levy required by Code of Virginia Section 36-139 and USBC Section 107.2. The levy is a state-collected pass-through to the Virginia Department of Housing and Community Development. The levy base differs: Fairfax applies the 2% to the combined building permit + plan review subtotal, while Chesterfield applies the 2% to its flat $114 building permit only. Washington, DC does not apply the Virginia levy because it is not a Virginia jurisdiction; its 10% Enhanced Fee is a separate DC surcharge.

Calculate Your Virginia Retaining Wall Permit Fee

The PermitPrice fee calculator supports the formula-based jurisdictions at the formula level: Fairfax's 3% declared-value formula and Chesterfield's flat fee are both engine-supported. The Washington, DC per-$1,000 rate is documented on the DC retaining wall guide. Enter your jurisdiction and declared construction value - the calculator applies the correct verified formula automatically. For jurisdictions without a discrete retaining-wall line item, confirm the applicable fee with the building department.
