What Is Mechanical & Electrical Permit?

Definition

In Oregon, replacing a furnace, heat pump, AC, or water heater requires a mechanical permit (plumbing too, for water heaters) with a final inspection, and the dedicated circuit a heat pump or heat-pump water heater needs takes a separate electrical permit — sometimes issued by two different city offices for the same address.

Why it matters for your home

In much of western Washington County, mechanical and electrical permits for the same job come from different offices entirely (in Cornelius, for example, mechanical runs through Forest Grove's Building Division while electrical runs through Washington County) — a detail that trips up unlicensed or out-of-area contractors.

What to do about it

Ask directly whether your quote includes pulling both the mechanical and electrical permit where both apply, and confirm which office issues each for your specific city.

Money term — the details

Which office issues permits in my city?
It varies by city and sometimes by permit type — see the permits & licensing guide for the specific office for every city in our service area.
What happens if the work was done without a permit?
It surfaces almost every time at home sale via Oregon's seller disclosure requirements, and fixing it later means pulling an "as-built" permit — often with walls opened for inspection and roughly double the fees of doing it right the first time.
