General Building Permit Information
Applying for a Permit
Prior to commencing construction, the contractor, owner, or builder must first apply to obtain a permit. Obtaining a permit may require the interaction and approval of several agencies outside of the Building Department; with small exception, each of these agencies charges fees for their review procedures. The Building Department works to coordinate the involvement of other agencies in the permitting process to obtain a building permit in the most expedient manner while maintaining the county’s high level of quality. This service is not a substitute for a customer’s responsibility to interact with all participating agencies.

Design Reviews
Design reviews may be secured prior to a permit application. Applicants may apply to many of the outside agencies independently prior to applying for a building permit, and are strongly advised to do so, when applicable. Not all agencies are required by statute to adhere to strict processing timelines in a manner similar to the Building Department.
