Check our our FAQ section with some great how-to documents that will step you thru the processes.
Notice regarding current processing timelines - Due to recent staff shortages and increased applications, the Building Division is experiencing delays in permit processing. We have brought in additional outside consultant services and staff to minimize any delays. 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.
Please be aware due to the demand and workflow at this time emails and phone calls are taking 1-2 business days for a response. We thank you in advance for your patience and ask that our clients allow us to reply to your email or phone call as calling or emailing multiple times adds to the backlog and prevents other clients from receiving our services in a timely manner.
