Do I need a permit for a heat pump in Bellingham?
Yes, a mechanical permit is required. Which office issues it depends on whether your address is inside city limits, and many “Bellingham” addresses are not.
The short answer
Yes. A heat pump or mini split needs a mechanical permit, and the electrical circuit needs its own electrical permit. Inside city limits the City of Bellingham Building Services issues it through the eTRAKiT portal; unincorporated Whatcom County addresses go through Planning & Development Services. We pull the mechanical permit and meet the inspector.
Your mailing address does not settle jurisdiction
The City says plainly that many properties with Bellingham mailing addresses are actually in unincorporated Whatcom County. That distinction decides which office reviews the permit, what it costs and who shows up for inspection, so we confirm it with the City IQ address tool before filing anything.
Two permits, two trades
The mechanical permit covers the equipment, refrigerant piping and condensate. A new dedicated circuit, a disconnect at the outdoor unit, or any panel work is electrical scope and needs an electrical permit, which is filed by a licensed electrical contractor rather than by us. We coordinate the sequence so the electrical is inspected and energized before we commission the system.
What we handle and what stays yours
We pull the mechanical permit and we are there for the inspection, which is a genuine part of the job rather than a favor. What stays with you is anything tied to your property rights: a Sudden Valley architectural review submittal, an HOA approval, or a historic-district exterior review. Tell us early if any of those apply, because approval timelines drive the install date more than our schedule does.
Why an unpermitted install costs you later
A permit record is what a buyer’s inspector and your insurer look for, and an unpermitted mechanical change can surface at the worst possible moment during a sale. Rebate programs also expect code-compliant work by a qualified installer. Skipping the permit saves a small fee and buys a problem that is far more expensive to unwind.
