Quick answer
Mechanical is one of the three trade permits on the Building Department's published permits-required list, and the Mechanical Permit Application (prefix PM) asks the applicant to circle whether the equipment is NEW or REPLACE EXISTING, so replacements are permitted work too. The city's own homeowner inspection program is built around furnace and air conditioning replacements, which confirms those jobs carry permits and inspections. A mechanical permit is separately required when a pool heater is installed. Permits can be pulled by the homeowner or a State of Michigan licensed contractor and are applied for online through BS&A Online. Per Fire Marshal Bulletin P20-19, permissible residential A/C tonnage is tiered by house size, from 3 ton for homes under 1,800 square feet up to 5 ton for homes over 3,300 square feet, normally one unit.

How to apply in Sterling Heights
In Sterling Heights, a residential HVAC (mechanical) permit application must identify the covered equipment and scope of work, since installing, altering, or replacing a heating or cooling system is regulated work that cannot start until the application is submitted and the permit issued. The equipment itself must be picked by a real sizing calculation rather than a rule of thumb.
What most HVAC permit applications include:
- For Sterling Heights, a mechanical permit is required before anyone may install, alter, repair, remove, convert, or replace a heating, ventilating, or air conditioning system regulated by the code, and the work may not begin until the application is submitted and the permit is issued (IRC R105.1).
- For Sterling Heights, the application identifies the specific equipment being installed, such as a furnace, heat pump, or air conditioner, since the unit must be installed according to its listing and the manufacturer's installation instructions (IRC M1401.1).
- For Sterling Heights, the proposed equipment location must leave the clearances needed to clean coils and replace filters, blowers, motors, and controls after installation (IRC M1401.2).
- For Sterling Heights, the application carries the equipment sizing basis: ACCA Manual J building loads and Manual S equipment selection, or another approved sizing method, not a rule of thumb (IRC M1401.3).
- For a split system, the work covered by the permit includes refrigerant suction line insulation, since the piping is inspected against that standard once installed (IRC M1411.6).

Inspections and closing out your permit
In Sterling Heights, mechanical work gets a rough in inspection after the ductwork, refrigerant lines, and gas piping are in but before they are covered or concealed, followed by a final inspection that confirms the equipment operates correctly and its clearances, combustion air, and condensate disposal are in place. A straight equipment changeout with no new ductwork commonly gets a single final inspection instead of a separate rough in trip.
- In Sterling Heights: rough inspection of the mechanical and gas systems must be made before the work is covered or concealed, before fixtures or appliances are set or installed, and before the framing inspection (IRC R109.1.2).
- In Sterling Heights: where a cooling coil is added to an existing warm air furnace, the rough in confirms the coil is not installed upstream of the heat exchanger unless the furnace is listed for it, and that the blower can handle the added static pressure (IRC M1411.2).
- In Sterling Heights: the rough in and final both confirm the appliance access opening and working space are large enough to service the unit (IRC M1305.1).
- In Sterling Heights: at final inspection, the inspector verifies the equipment has adequate combustion air, with openings kept clear for the distance the code requires (IRC M1402.3).
- In Sterling Heights: final inspection also checks that the condensate line drains to an approved point of disposal with the required slope and does not create a nuisance (IRC M1411.3).
- In Sterling Heights: for a straight equipment changeout with no new ductwork, many permit offices require only a single final inspection, while a new installation still gets a rough in inspection before the final (common local inspection practice).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Sterling Heights permit portal or by phone at 586-446-2360.

- Where do you apply for an HVAC permit in Sterling Heights?
- You can apply through the Sterling Heights permit portal or contact the City of Sterling Heights Office of Building (Building Division), Office of City Development directly. The links are listed on this page.
- Can a homeowner pull an HVAC permit themselves in Sterling Heights?
- Under Michigan law (MCL 339.2403(b), (c); MCL 339.2401(a)(iii), (b)(ii)(A); MCL 339.5737(3)(g); MCL 339.6107(2)(d); MCL 339.5819): Yes. A Michigan homeowner may pull the building permit and do the work on their own home without a residential builder license, because the licensing article both defines the trade to exclude them and exempts them outright. MCL 339.2401(a)(iii) says a residential builder is a person that erects a residential structure except for the person's own use and occupancy on the person's property, and MCL 339.2403(b) exempts an owner of property with reference to a structure on the property for the owner's own use and occupancy. Own use and occupancy is the condition, so the exemption does not cover building to sell, and MCL 339.2403(c) limits owners of rental property to maintenance and alteration of that property. The statute sets no cap on how many times a homeowner may use the exemption; the only frequency rule in the article catches purchase, substantial rehabilitation, and resale of the same structure more than twice in 1 calendar year, and MCL 339.2401(b)(ii)(A) exempts work for the person's own use and occupancy from even that. Homeowners can also pull their own trade permits: electrical work in a single family home and accompanying outbuildings owned and occupied or to be occupied by the person doing the work (MCL 339.5737(3)(g)), their own plumbing, building sewer, or private sewer in their single-family dwelling if a permit is secured (MCL 339.6107(2)(d)), and a heating or refrigerating system if the owner affirms in the permit application that they are or will become the owner and occupant (MCL 339.5819). Confirm how Sterling Heights applies this before you apply.
