Local Project Overview
Shed Installation · St. Mary's County, Maryland
Often exempt under 200 sq ft
In Maryland, a Shed Installation under 200 sq ft generally does not require a state building permit. At or above 200 sq ft, a permit is required.
Maryland enforces a Statewide + local building code (IRC 2021). Local zoning, property-line setbacks, and any electrical or plumbing work can still require approval in St. Mary's County, so confirm the details with Montgomery County Department of Permitting Services.
