Garage Construction · Calvert County, Maryland
Permit required
In Maryland, a Garage Construction requires a building permit.
A garage almost always requires a building permit. Attached garages always need one; a detached garage is exempt only if it is under 200 sq ft with no electrical, which most garages exceed. Plans are reviewed under the Statewide + local code (IRC 2021); apply through Calvert County Inspections and Permits before work begins.

Building a new detached or attached garage is treated similarly to a major home addition. It involves pouring a concrete slab, structural framing, roofing, and electrical work. Due to zoning laws governing property setbacks and impervious surface limits, the permitting process for garages is highly rigorous.
With a growing population of around 94,313 residents, Calvert County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
