Quick answer
Corpus Christi requires a mechanical permit for the ordinary residential HVAC jobs: a new A/C unit, a new heat furnace, duct outlets or a system, adding or moving a kitchen hood vent, and adding a restroom exhaust fan. The two published exceptions are narrow, covering the installation of a portable HVAC appliance and the replacement of minor parts so long as the equipment does not become unsafe. The permit comes from the city on the Trade Permit Application (Form 1026), which has a Mechanical box and a Residential box, and a homeowner working on their own homestead may pull it instead of hiring out. Rough-in and Final are the published mechanical inspections, and A/C Change out is eligible to be inspected virtually.
Typical threshold: A mechanical permit is needed to install a new A/C unit, a new heat furnace, duct outlets or a system, to add or move a kitchen hood vent, or to add a restroom exhaust fan; the two published exceptions are installing a portable HVAC appliance and replacing minor parts as long as the equipment does not become unsafe.

How to apply in Corpus Christi
In Corpus Christi, 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 Corpus Christi, 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 Corpus Christi, 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 Corpus Christi, 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 Corpus Christi, 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 Corpus Christi, 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 Corpus Christi: 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 Corpus Christi: 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 Corpus Christi: 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 Corpus Christi: 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 Corpus Christi: 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 Corpus Christi: 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 Corpus Christi permit portal or by phone at 361-826-3240.

- Where do you apply for an HVAC permit in Corpus Christi?
- You can apply through the Corpus Christi permit portal or contact the City of Corpus Christi Development Services Department, Building Division directly. The links are listed on this page.
- Can a homeowner pull an HVAC permit themselves in Corpus Christi?
- Under Texas law (Tex. Occupations Code 1305.003(a)(6), 1301.051; Tex. Local Government Code 233.157(c)): Texas licenses individual construction trades rather than general contractors, so no state statute requires a license to act as your own general contractor on your own house. For electrical work, the state licensing law does not apply to work performed in or on a dwelling by a person who owns and resides in it, but only where no municipal ordinance specifically regulates that work, so city electrical licensing and permit rules still control inside city limits (Occupations Code 1305.003(a)(6)). For plumbing, a property owner does not need a state license to perform plumbing in the owner's homestead (Occupations Code 1301.051). In opt-in counties' unincorporated areas, an individual who builds their own house or acts as their own contractor is exempt from the Class C misdemeanor penalty for inspection notice failures if they intend to use the home as their primary residence (Local Government Code 233.157(c)). None of these exemptions waive local permit or inspection requirements where they apply. Confirm how Corpus Christi applies this before you apply.
