Frederick County Deck Permit Requirements
In Frederick County, any deck attached to the house requires a building permit. Freestanding decks over 200 square feet also typically require a permit. The application requires a site plan showing property lines, the house footprint, and the proposed deck location with setback dimensions. A framing plan showing joist size, span, and ledger connection method is also required. Some municipalities within the county — the City of Frederick, Brunswick, Thurmont — have their own building departments with slightly different processes.
HOA approval is a separate process from the county permit and must often be obtained first. We coordinate both processes and flag which one needs to happen in which order for your specific property.
