Commercial construction includes new buildings and work on, within, or added to existing buildings. Work on existing structures is often referred to as a tenant improvement. A permit technician can help you determine your project requirements and related fees.
Fees are established by county ordinance and are calculated automatically by computer during the application process. You will receive a fee estimate during your initial visit to our office and a final cost when you submit your applications.
Permit fees cover the cost of processing, plan review, and inspections to ensure code compliance and safety standards are met.
We recommend meeting with a plans examiner at the early stages of design to avoid code corrections later in the process. You may schedule an appointment by contacting Michelle Finley at 564.397.4088 or firstname.lastname@example.org.
