Permitting for an Accessory Structure in Union County


Permitting is at the full discretion and responsibility of each homeowner. An accessory structure in Union County can require up to 4 permitting applications to different departments and municipalities, not including HOAs.


  1. 811 - Underground Utility Marking

    Be sure that your building footprint is clearly marked with flags. 811 will send someone to mark underground utilities on your property. This is needed for Step 3 with Environmental Health, but It's best if you start this first so that it's ready by the time you submit your application to Environmental Health. 811 Request | No cost | Processing: ~3 Days

  2. Zoning Permit Application for Accessory Structure

    This type of permit is directly through your local municipality and ensures residents stay within certain size, location and land-use guidelines. Choose your municipality below. Not sure?
