Building Permit and Contractor Registration

Permit Requirements and Fees

Building Permit (BDP)

A permit is required when you construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure, or to erect, install, enlarge, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system or when you construct, place or modify a sign. Projects that require or do not require a building permit can be found here.

Building permit fees are based on the valuation of the project. The valuation is the total cost of the materials and labor. Some projects are calculated using a cost/square foot equation.

If you need to request the cancellation of a building permit and refund of fees, please use the form below.
