What is different about home addition in Virginia
The USBC preempts local codes, so localities cannot add requirements — but Northern Virginia fee schedules and review queues still run far above the rest of the state.
Owner-builder: Homeowner permits allowed on owner-occupied property. Home Addition generally requires a licensed contractor to pull the permit, even where owner-builder status is available.

Frequently asked questions
How long does an addition permit take in Florida?
Plan review for an addition typically runs four to twelve weeks depending on the jurisdiction, and that is after the sealed drawings are complete. Coastal and flood-zone properties take longer because of elevation review.
Do impact fees apply to a home addition?
Many Florida counties assess impact fees on added conditioned square footage. The fee is usually calculated per square foot and can add thousands to a large addition, so ask for the fee estimate before design.
