Building Permit Information

Permitting Process

Permit applications are completed online and include the opportunity to upload all necessary documents directly with your application. If you don't have the ability to scan your materials please bring the physical copies to the Community Development Department and we will assist in getting them scanned. Staff will review the documents to insure they comply with the City's Codes. If questions or concerns arise during the processing of the application the applicant will be contacted via the information provided on the application. Once your permit is approved you will receive an email which will include information on how to obtain your permit, the applicable permit fees, and any other pertinent information.

When Are Permits Required?

Permits are required before beginning new construction, repairs, additions, alterations, or demolition projects.

Permits are not required for painting, flooring or tiling.  Non-structural repairs to interior surfaces don't require permits provided no changes are made to the structural framing, electrical, or plumbing. Emergency repairs may be addressed without immediately obtaining a permit, but the permit must be applied for within 7 days of the emergency repair work being performed.

It is impossible to create a comprehensive list of all possible projects.  Items not on the list may still need a permit.  If you don't see your project please contact the office for a determination.
