Shed permit rules in Harford County, MD — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
Harford County is stricter than most: a building permit is required for every residential accessory structure, including sheds, before construction starts. A prefabricated shed under 200 square feet skips only the construction plans, not the permit.
Harford County requires a building permit for all residential accessory structures before construction begins, and a prefabricated shed must be permitted before it is placed on the property. There is no small-shed permit exemption here, unlike many jurisdictions. For a prefabricated shed or one under 200 square feet, no construction plans are needed, just the site plan and application. Zoning setbacks still govern where the shed sits, so contact Planning and Zoning at 410-638-6442 for the district minimums. On lots with a well or septic, the Health Department sets separation distances from those systems.
Placing a shed without the required permit is illegal work and draws a stop-work order and fines. A shed set inside a zoning setback or too near a septic field must be moved.
