Your pre-fab shed requires a permit and inspections. For multi-unit, 2 story or stick built sheds follow the detached garage guidelines page.

Note: Prefab sheds less than 150 square feet, on skids and movable do not require a permit. All setback requirements apply.

Note: The site of the new shed is required to be approved by the Carroll County Zoning Administration and the Carroll County Health Department to ensure that the proposed structure meets the proper setbacks from property lines, septic systems, water infrastructure, etc. For help with site selection, please contact:

Carroll County Zoning Administration 410-386-2980

Permits Required

Your pre-fab shed will require a building permit/zoning application. If the shed includes electricity,  an electrical permit is required. If the shed includes running water, such as for a utility sink, a plumbing permit is also required. Please gather the construction documentation specified below and submit a building permit application and an owner/contractor affidavit. After the building permit is filed, have your licensed electrician submit an electrical permit application and/or have your licensed plumber submit a plumbing permit application.

Permit Process

Many factors affect the speed with which your application(s) are approved. For best results, it is critical that you carefully review your application and design documents prior to submission to ensure that all necessary documents are included and that the design is compliant with the county code. Normally, permits can be issued within 10-15 business days if the application is complete, accurate, and code-compliant.
