Permit fees for Electrical, Plumbing and Mechanical permits are based on the number of inspections plus unit costs (i.e. the number of circuits being installed for an electrical permit or the number of fixtures being installed for a plumbing permit). The final number of unit costs and inspections will determine the cost of a permit.
Building permits are based on the "Market Value" of the work to be completed. Fees for permits, if applicable, can be viewed online in the fee schedule (PDF).
