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.

   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
