Maryland Shed Permits: Guide By County

Beige workshop-style shed with windows and ramp entrance

If you’re thinking about adding a storage shed or garden building to your Maryland property, it’s important to make sure it’s allowed in your area before beginning your project. In this guide, we’ll explain who to contact for information about the shed permit process and how local zoning rules might affect your placement. And if you’re considering options, you can explore our Shed Models, or try out our 3D Builder to start designing the shed that fits your space and your style.

Do I Need a Permit to Build a Shed in MD?

Yes, in most cases. Maryland follows the International Residential Code (IRC). Though each county sets its own rules for when a permit is required, here are some common rules across the state:

  • The 200 Sq. Ft. Rule: In many Maryland counties, a building permit is not required for sheds 200 square feet or smaller. However, this is not universal. Some counties require permits for anything over 150 or even 100 square feet.
  • Zoning is Mandatory: Even if your shed is small enough to skip a building permit, you almost always need a Zoning Permit. This ensures your shed meets “setbacks” (distance from property lines) and doesn’t exceed “lot coverage” limits.

The Foundation: Maryland’s frost line and wind zones mean that larger sheds (usually over 200-400 sq. ft.) must have permanent foundations and tie-downs to meet safety codes.

Do I Need a Permit to Run Electricity to My Shed in MD?

Yes. You’ll need a permit to run electricity to your shed in Maryland, since electrical work is regulated under the state’s adopted electrical codes and enforced locally. 

Electrical permits are commonly required for:

  • Installing lighting or outlets in a shed
  • Running new electrical circuits from a dwelling to a shed
  • Adding panels or other electrical components

All electrical work is typically subject to inspection by the local authority having jurisdiction.

Do I Need A Floor Plan For My Shed In MD?

Maybe. Some Maryland jurisdictions require scaled drawings or floor plans as part of a shed permit application, while others may only require a site or plot plan.

When required, floor plans are used to confirm:

  • Shed dimensions and layout
  • Door and window placement
  • Compliance with local building and zoning rules

Documentation requirements vary by jurisdiction and shed size, so local confirmation is recommended.

What Customizations Can I Add To My Shed In MD?

Sheds in Maryland can often be customized with options like doors, windows, siding, roofing materials, and interior features such as shelving or loft space. These upgrades help adapt a shed for storage, workspace, or long-term durability.

Upgrades like electrical wiring, insulation, plumbing, or finished interiors usually require permits and local approval. Because rules vary by county and municipality, confirm allowed features with your local permitting office before finalizing your shed plans.
