Residential Mechanical Inspections

Mechanical permits are required for work on the heating, cooling or ventilation systems in a single family home or duplex. Installing a natural gas line, vent, fuel oil tank or chimney liner for appliances or other equipment is also considered mechanical work.

"Mechanical" includes all HVAC (heating, ventilating, air conditioning). This includes gas piping, ductwork, furnaces, heat pumps or air conditioning condensing units. All of these must be inspected prior to covering them up in the structure of a home, or putting them into service.
