How to apply in Pinellas County
In Pinellas County, 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 Pinellas County, 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 Pinellas County, 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 Pinellas County, 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 Pinellas County, 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 Pinellas County, 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 Pinellas County: 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 Pinellas County: 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 Pinellas County: 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 Pinellas County: 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 Pinellas County: 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 Pinellas County: 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 Pinellas County permit portal or by phone at (727) 464-3888.

- You can apply through the Pinellas County permit portal or contact the Pinellas County Building and Development Review Services directly. The links are listed on this page.
- Can a homeowner pull an HVAC permit themselves in Pinellas County?
- Under Florida law (F.S. 489.103(7)(a)-(c)): Florida lets you pull your own permit as an owner-builder under section 489.103(7), Florida Statutes, which exempts property owners from the contractor licensing law when they act as their own contractor and provide direct, onsite supervision of all work not performed by licensed contractors. The exemption covers building or improving a one-family or two-family residence or a farm outbuilding for your own occupancy or use, and commercial buildings only up to a $75,000 cost, and the property may not be built or improved for sale or lease. If you sell or lease the property within 1 year after completing the work, the law presumes it was built for sale or lease, which violates the exemption. To qualify, you must personally appear and sign the building permit application and sign a state-prescribed disclosure statement acknowledging that you are the party legally and financially responsible for the construction, that you must provide direct, onsite supervision, and that unlicensed people you use must be your own employees, bringing federal tax withholding and workers' compensation obligations. You may not hire an unlicensed person to act as your contractor and may not delegate supervision to anyone who is not licensed for the work being done; if these requirements are violated, the local permitting agency shall withhold final approval, revoke the permit, or pursue unlicensed-activity remedies. A separate narrow branch of the exemption also lets an owner take over and complete a permit on a one-family or two-family residence when the original contractor substantially completed the project. Confirm how Pinellas County applies this before you apply.
