Tips

  • Combined permits save money when a single project needs two trades at once (e.g., A/C replacement needs both electrical and mechanical) — ask about the $75 combined-permit flat fee before applying for two separate permits.
  • New construction/addition mechanical, electrical, and plumbing fees are charged per square foot IN ADDITION to the building permit fee — budget for all trades when estimating total project cost.
  • RV/mobile home parks are billed per space for electrical and plumbing, with a discount for additional spaces inspected during the same visit.
