Permits & licensing, translated
Which office issues what in each city, how to check any contractor's license in 90 seconds, and why the bargain unpermitted job is the expensive one. Verified July 4, 2026.
In brief
What permits HVAC and water heater work actually requires in Washington County and nearby cities, which office issues them in each town, how to verify any Oregon contractor's CCB license, and why unpermitted work resurfaces at home-sale time. Best Owner Direct HVAC & Electrical (CCB# 199049) pulls every required permit and schedules every inspection — it's included in the quote, never an upsell.
Do HVAC and water heater projects here really need permits?
Yes — in Oregon, replacing a furnace, heat pump, AC, or water heater requires a mechanical (or plumbing) permit with inspection, and the dedicated circuit a heat pump or heat-pump water heater needs requires an electrical permit. The catch in the western metro is who issues them: many cities run their own mechanical permits but contract electrical permitting to the county, so one heat pump job can involve two different government offices. The table below is the map. On our jobs, permits and inspections are included in the quote — we pull them, schedule them, and hand you the record.

Verify before you hire
Check any contractor's CCB license in 90 seconds.
Every paid contractor in Oregon must hold an active CCB license with a surety bond and insurance behind it. Hiring unlicensed means no bond to claim against, no CCB dispute process, and — if their work causes damage — a homeowner's insurance claim that may be denied. Start with ours:
Best Owner Direct HVAC & Electrical — Oregon CCB# 199049
Look us up on the Oregon CCB license searchSearch the official registry
Enter the CCB number (it must appear on every bid and invoice), business name, or owner name at search.ccb.state.or.us.
Confirm the status is Active
A license can exist and still be suspended — usually because the bond or insurance lapsed. “Active” is the only acceptable answer.
Check bond, insurance, and history
Verify the surety bond and liability insurance are current, then open the complaint history — it shows up to 10 years of citations and unresolved disputes.
For the electrical side of an install, go one step further
A CCB license alone isn't enough: whoever wires the new circuit for a heat pump or heat-pump water heater must also hold an electrical trade license from the Oregon Building Codes Division. Ask who holds it on your job — on ours, it's our own licensed team.
The part sellers learn the hard way
Unpermitted work doesn't disappear. It waits for closing day.
Oregon's seller disclosure statement (ORS 105.464) asks point-blank whether work was done, whether a permit was required, and whether a final inspection happened. Answer falsely and you invite a misrepresentation lawsuit; answer honestly and buyers, lenders, and insurers treat undocumented HVAC work as the fire hazard it might be — FHA/VA lenders routinely demand tear-out or retroactive permits before funding. If the disclosure reveals it, the buyer can walk within five business days (ORS 105.475). And "grandfathering" is a myth: work is only legal if it was permitted when built. Retroactive "as-built" permits typically cost roughly double, often with finished walls opened for inspection.
The moral is boring and inexpensive: pull the permit the first time. On every Best Owner Direct job it's already in the price — and the final inspection is your independent, public-record proof the work is right.
Quick answers
Permit questions homeowners actually ask
Do I need a permit to replace a furnace, heat pump, or water heater in Washington County?
Yes. In Oregon, replacing a furnace, heat pump, AC, or water heater requires a mechanical (and for water heaters, plumbing) permit with a final inspection — and the dedicated circuit a heat pump or heat-pump water heater needs takes a separate electrical permit. In much of western Washington County the two permits come from different offices: in Cornelius, for example, the mechanical permit runs through the Forest Grove Building Division while the electrical permit runs through Washington County. We pull both on every job — it's included, not an upsell.
Who pulls the permit — the homeowner or the contractor?
Normally the contractor, and for electrical work Oregon law requires the licensed electrical contractor performing the work to obtain the permit. A homeowner can pull their own permits on their own home, but must sign a property-owner responsibility statement accepting liability for code compliance. If a contractor asks you to pull the permit for work they're doing, treat it as a red flag — it usually means they aren't licensed to.
How do I verify a contractor's CCB license?
Search the license number, business name, or owner name at the Oregon CCB's official lookup (search.ccb.state.or.us). Check four things: the status says Active, the surety bond is current, liability insurance is on file, and the complaint history is clean. For HVAC and electrical work, the CCB license alone isn't enough — the people doing electrical work must also hold trade licenses from the Oregon Building Codes Division. Our license is CCB# 199049; look us up any time.
What happens if I sell a house with unpermitted HVAC or electrical work?
Oregon's seller disclosure statement (ORS 105.464) asks directly whether work was done, whether a permit was required, and whether a final inspection was obtained — and you must answer to your actual knowledge. Disclosed unpermitted work scares buyers, lenders, and insurers; undisclosed unpermitted work invites a lawsuit; and if the disclosure reveals it, the buyer can revoke within five business days (ORS 105.475). Fixing it later means "as-built" permits — often with walls opened for inspection and roughly double the fees. The inexpensive permit at install time is the bargain.
How much does a permit cost, and how long does inspection take?
Fees are set by each jurisdiction's adopted fee schedule plus a state surcharge — for a straightforward residential change-out they're typically a small fraction of the project cost, and we include them in the quoted price. Inspections in most metro jurisdictions schedule online or by phone and are usually fulfilled the next business day. The final inspection is your independent, on-the-record confirmation the work is safe and to code.
