How to apply in Chesterfield County

In Chesterfield 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 Chesterfield 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 Chesterfield 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 Chesterfield 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 Chesterfield 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 Chesterfield 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.

  1. In Chesterfield 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).
  2. In Chesterfield 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).
  3. In Chesterfield 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).
  4. In Chesterfield 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).
  5. In Chesterfield 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).
  6. In Chesterfield 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 Chesterfield County permit portal or by phone at (804) 751-4990.

Under Virginia law (Va. Code 54.1-1101(A); 13VAC5-63-80 (USBC Sections 108.3, 108.4)): Yes. Va. Code 54.1-1101(A) exempts any person who performs or supervises construction, removal, repair, or improvement of no more than one primary residence owned by them and for their own use during any 24-month period. The exemption covers the whole licensing chapter, including tradesman licensing for electrical, plumbing, and HVAC, so it reaches trade work on the owner's own primary residence.

Limits: one primary residence per 24 months, for the owner's own use; rental and investment property work is not covered. Confirm how Chesterfield County applies this before you apply.
