Deck Construction Permits in Alexandria
Local Rule
City of Alexandria Department of Building and Fire Code Administration
The city's own Permit Requirements page lists "Decks, Porches, Stoops" among the categories always needing a permit, and separately lists accessory structures over 200 square feet, fences over 6 feet, and retaining walls holding 2 feet or more of soil, tighter than the usual 4 foot figure used in many jurisdictions. A freestanding deck under 200 square feet may still be exempt under the statewide small-deck rule, but an attached deck needs a permit regardless of size. Alexandria's own fee schedule prices residential alterations at $0.30 per square foot of gross floor area or $18 to $19.75 per $1,000 of construction cost, whichever is greater, and requires a 35 percent deposit toward the estimated permit fee before plan review begins.

How This Compares to Virginia Statewide

The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit.
