Installing Accessory Structure/ Pre-fab Shed/ Storage Building

It’s about long term Building Efficiency and Safety!

Your pre-fab shed requires a permit and inspections. For Accessory Structure, or stick built sheds follow the detached garage guidelines page.

NOTE: Prefab sheds less than 200 square feet, on skids and movable DO NOT require a permit. All setback requirements apply.







Permits Required

Your Accessory Structure will require a building permit. If your shed will be wired with electricity, you will also need an electrical permit. If your shed will feature running water, such as a utility sink, you will also need a plumbing permit. Please gather the construction documentation specified below and submit a building permit application, and an owner/ contractor affidavit. After the building permit is filed, if applicable, have your licensed electrician submit an electrical permit application and/ or have your licensed plumber submit an plumbing permit application. For Electrical Permit check with your local provider.

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 county code. Normally, permits can be issued within 1 business day if the applications are complete, accurate and code-compliant.

 Construction Document Requirements

Submitted documents must contain sufficient information for the plan reviewer to be able to review the proposed construction.

  • Site Plan
  • Location of the proposed structure
  • Measurements from the proposed structure to each property line
  • Location of any existing structures
  • Location of existing/proposed driveway(s)
