Non-Residential

Get the Information You Need to Build with Confidence

A building permit is required for non-residential construction projects, including new buildings, additions, renovations and changing the use of a building. Permit applications must include required drawings, documents, and fees to be considered complete. Use this page to find the necessary forms, submission requirements, and additional information on zoning and inspections. Additional information may be required depending on the application type and individual circumstances.

If you want to change the way you use all or part of a building, you may need a change of use permit, even if you're not planning any construction. A building evaluation may have to be done to make sure that the existing building can safely accommodate the proposed use. For example, a permit would be required when changing an existing office space to a retail space.
