Building & Permits

Welcome Sign at City Hall


From now through the end of this summer, the City’s Community Development Department, including Permit Services, will be operating at a reduced staffing level. Between this staffing reduction and COVID-19, the City’s response time to permit-related inquiries/messages as well as time for the processing, review, and issuance of permit applications will be particularly affected.

Customers may experience delays of up to several days in response to general messages and similar inquiries, including tree inspection requests, so please plan accordingly. Expect delays that are several weeks beyond the City’s standard response times for review of permit applications, including submittals and resubmittals.

Thank you for your patience. We look forward to restoring our level of service as staffing returns to regular levels.
