A permit is required regardless of the size of an accessory structure. You will receive either a zoning permit if under 12 feet in any direction (length, width, or height) or a building permit if an accessory structure exceeds 12 feet in any direction (length, width, or height).

Accessory structures include but are not limited to:

  • Detached garages and carports
  • Storage sheds and gazebos
  • Greenhouses
  • Pool houses

Additions include but are not limited to:

  • Converting an unheated to heated space (i.e. converting an attic or basement into a room)
  • Adding new space to an existing structure
  • Adding to the footprint
  • Adding a second floor
  • Enclosing a garage
  • Attached mother-in-law suites
  • Sunrooms
  • Dormers

  2. All contractor information (General contractor and sub-contractors) must be entered into the portal when submitting the project.
  3. If you are a homeowner acting as the contractor for your project, the Owner Exemption Affidavit is required.
