Do I need a permit for shed or accessory structure in Frederick?

Permit may be required

It depends. Whether shed or accessory structure needs a permit in Frederick comes down to the details of your project.

The 2021 IRC exemption for small detached accessory buildings (200 sq ft) is part of the State's adopted code, but counties and municipalities may amend it, so it does not settle the question statewide. Local jurisdictions may amend the Standards, and a local amendment prevails where it conflicts (Public Safety 12-504); the county, Baltimore City, or a municipality with its own code office sets the actual permit list. Land within 1,000 feet of tidal waters or tidal wetlands is generally in the Chesapeake Bay or Atlantic Coastal Bays Critical Area, where State law caps lot coverage (often 15 percent, or 25 percent on some older small lots) and a separate local critical area review may apply. Zoning setbacks and any electrical work in the shed still apply even where no building permit is required.
