Shed Installation · Washington County, Maryland
In Washington County, a Shed Installation under 400 sq ft generally does not require a building permit. At or above 400 sq ft, a permit is required.
Washington County's own permit checklist sets its shed exemption at 400 square feet, notably more generous than Hagerstown, the county seat, which exempts a shed only under 100 square feet within its own city limits; a shed exempt in the surrounding unincorporated county at, say, 300 square feet would need a full building permit inside Hagerstown. The county's fee structure is size-based rather than flat, charging $0.10 per square foot of the shed floor plan on top of a $65 application fee and a $15 technology fee, and a shed over 400 square feet additionally triggers a footing and foundation plan requirement, including pier footers, that a smaller exempt shed does not need. Building permits in Washington County are handled under the Washington County Permitting Office (unincorporated areas) building code (IRC Maryland Building Pe). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Washington County Permits and Inspections.
