Over the Counter Plan Review - Building and Fire Permits

Plans Examiners are available to review plans for simple residential projects at the Permit Counter on Monday and Wednesday at 10 am. Reviews are completed at the permit counter with the applicant. If the project is approved, permit center staff issue the permit the same day. All applicants MUST sign in before 10:15 am, and will have their applications reviewed by permit staff in the order of sign in. Applicants who arrive after the 10:15 am sign in time will be directed to return on the next available OTC day.
