Heat pump permits inside Bellingham city limits
A heat pump needs a mechanical permit, and inside city limits that means City of Bellingham Building Services and the eTRAKiT portal. First, check whether your address is actually in the city — many are not.

A heat pump installation is permitted work. Inside Bellingham city limits the mechanical permit comes from City of Bellingham Building Services, filed through the city’s eTRAKiT online portal, and any electrical work is separately permitted by a licensed electrical contractor. The step almost everyone skips is checking whether the address is actually inside city limits. A great many mailing addresses that read "Bellingham, WA" sit in unincorporated Whatcom County — the City says so explicitly — and that changes the permit authority, the fee schedule and the inspector.
First, confirm your address is really in the city
A Bellingham mailing address is not the same thing as a Bellingham municipal address. The postal city covers a substantial area of unincorporated Whatcom County, and the City of Bellingham states plainly that many addresses with Bellingham mailing addresses are outside the city limits.
This is not a technicality. It determines which building department issues your permit, which fee schedule applies, whose inspector shows up, and which zoning setbacks govern where the outdoor unit can sit. Getting it wrong means a permit application to the wrong jurisdiction and a delay.
The City’s own mapping tool, City IQ, is what settles it, and the city permit portal is at cob.org/services/permits. We confirm the jurisdiction as part of quoting rather than assuming from the mailing address, and the answer is genuinely surprising often enough that we always check.
- Look the parcel up in the City of Bellingham’s City IQ mapping tool to confirm inside or outside city limits
- If inside: mechanical permit through City of Bellingham Building Services via the eTRAKiT portal at cob.org/services/permits
- If outside: mechanical permit through Whatcom County Planning and Development Services instead
- Confirm zoning setbacks for mechanical equipment in the correct jurisdiction before finalising the outdoor unit location
- Confirm whether an HOA or condominium association also requires exterior equipment approval
- Have the equipment model numbers and AHRI data ready — the permit application describes the specific system
- Arrange the separate electrical permit through the licensed electrical contractor doing that scope
What the mechanical permit covers
The mechanical permit covers the heating and cooling equipment itself: the outdoor unit, the indoor units or air handler, the refrigerant piping, condensate management, any ductwork, and the equipment’s attachment and clearances.
It does not cover the electrical work. Circuits, disconnects, panel changes and the wiring to the equipment are electrical scope, permitted separately and performed by a licensed electrical contractor. We do not hold an electrical contractor licence and we will not pretend otherwise — we coordinate with the electrical contractor and sequence the two scopes so the inspections line up.
Gas piping, where a project touches it, is another separate licensed scope. For a straight heat pump or ductless installation it usually does not arise; for a hybrid or a furnace project it can.
eTRAKiT and how the application actually goes
The City runs permitting through eTRAKiT, its online portal, reachable from cob.org/services/permits. A residential mechanical permit for equipment replacement is a comparatively straightforward application: the property, the scope, the specific equipment, and the contractor’s registration.
What slows applications down is missing equipment detail. The application describes a specific system, so the model numbers need to be settled, which is one reason we do not order equipment and file a permit in the same hour.
We file it, we track it, and we deal with any correction request. Fees are set by the City’s current schedule and appear as a line on your quote rather than a surprise later.
Who pulls it, and why that matters to you
We pull the mechanical permit and we meet the inspector. That is a deliberate position rather than a courtesy, because the alternative — a homeowner-pulled permit on work a contractor performed — shifts responsibility for the work onto the homeowner.
If someone quotes you a heat pump installation with no permit line and no mention of inspection, ask directly whether they intend to permit the work. Unpermitted mechanical work turns up later in two expensive places: a home inspection during a sale, and a warranty or insurance claim where the installation’s compliance is in question.
There is one legitimate case where the permit is yours: a genuinely homeowner-performed installation. If you are doing a DIY mini split kit and we are commissioning it, the permit and the inspection are yours to arrange, and we will tell you that up front and explain what the inspector will look for.
What the inspector looks at
A mechanical inspection on a heat pump install is mostly about the things that cause failures later. Equipment clearances to combustibles, to grade and to property lines. Secure and level mounting of the outdoor unit. Refrigerant line support, protection where lines pass through the building, and sleeving at penetrations.
The inspector also looks at condensate: where it goes, whether it is trapped and sloped properly, and whether an interior installation has appropriate overflow protection. And they look for the required labelling and the disconnect, though the disconnect itself belongs to the electrical inspection.
Corrections happen and are not a crisis. What matters is that somebody with authority looked at the installation, which is the whole value of the process. We schedule the inspection, attend it, and handle any corrections as part of the job rather than as a change order.
Timeline, and how permitting fits the schedule
Permitting is rarely the long pole. Equipment lead time usually is, particularly for a specific cold-climate model or a multi-zone outdoor unit with a certain port count.
The practical sequence is: site visit and load calculation, equipment selection, quote, permit application with the model numbers settled, equipment ordered, install, inspection. Running the permit application and the equipment order in parallel is normal.
Where schedules slip is when a scope changes mid-project — a duct problem found in the crawlspace, a panel that turns out to need work — because a scope change can mean a permit revision and a second trade. That is one more reason the site visit is worth doing properly rather than quoting off photographs.
Questions Bellingham homeowners actually ask
- Do I need a permit to install a heat pump in Bellingham?
- Yes. A heat pump or ductless installation requires a mechanical permit, and any associated electrical work requires a separate electrical permit pulled by a licensed electrical contractor. Inside city limits the mechanical permit comes from City of Bellingham Building Services through the eTRAKiT portal.
- How do I know if my address is inside city limits?
- Check the parcel in the City of Bellingham’s City IQ mapping tool rather than trusting the mailing address. The City states explicitly that many addresses with Bellingham mailing addresses are outside the city limits, in unincorporated Whatcom County, where Whatcom County Planning and Development Services is the permit authority instead.
- Do you pull the permit or do I?
- We pull the mechanical permit and meet the inspector on work we perform. The exception is a genuinely homeowner-installed system that we are only commissioning, where the permit and inspection are yours to arrange — and we will say so clearly at the start rather than leaving it ambiguous.
- Is a permit needed for a like-for-like replacement?
- Treat the answer as yes and verify with the jurisdiction for your specific scope. Replacement of mechanical equipment is generally permitted work, and the fact that the old unit sat in the same place does not exempt the new one from current clearance, mounting and condensate requirements.
- What happens if work was done without a permit before I bought the house?
- It is a common situation and it is usually resolvable. The building department can advise on the path, which may involve an inspection of existing work. It is worth dealing with before you sell, because an unpermitted mechanical installation is the kind of thing a buyer’s inspector finds and a lender asks about.
