Additional 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 exceptions, 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.
