Building permits are required for new buildings, renovations and additions to existing buildings to ensure all structures within the City are safe to occupy. A completed application and two full sets of plans are required for permit submittals.

Types of Permits

There are many types of building permits based upon the construction and improvements you are seeking to do. However, there are two types of permits the City typically issues:

  • Over the counter permits: Over the counter permits are generally routine in nature and can be issued while you are waiting, such as re-roofing, water heaters, furnace, new windows, etc.
  • Permits for new construction, additions or remodeling.

All other permits take time to review due to the complexity of the project. The City guarantees project review timeframes based upon the permit type.

  • New Residential, Residential Remodels and Additions, Decks, Basement Finishes – five business days
  • Commercial Accessory Structures and Tenant Finish and Remodels – ten business days
  • New Commercial, Large Commercial Additions, Residential Master Plans – 15 business days
