Planning, Building & Environmental Services

NEW! Attention Customers:  Due to recent staff shortages and increased applications, the Building Division is experiencing delays in permit processing and inspection scheduling.  We have brought in additional outside consultant services and staff to minimize any delays.  Please contact the Building Official if you have an urgent matter.  We thank you for your patience and understanding at this time and look forward to returning to our normal level of service as soon as possible.

NEW! NOTICE: New Building Code Requirements go into effect June 17, 2021 to improve fire protection for all new residential construction and rebuilds. Please refer to Ordinance No. 1468 and Resolution 2021-50 for details.
