Gwinnett County HVAC Permit Requirements
In Gwinnett County, Georgia, obtaining an HVAC permit is a crucial step for most installations, alterations, or replacements of mechanical systems. The Gwinnett County Department of Planning and Development is responsible for issuing these permits. Applications for construction permits, including those for HVAC work, are submitted through the county's ZIP Portal. A permit is issued after the plan review process is completed, applicable fees are paid, and contractor information is provided. Inspections are required during construction, and these can also be scheduled online via the ZIP Portal using the permit case number.
For new home construction, building permits encompass electrical, HVAC, and plumbing inspections. Licensed HVAC subcontractors must submit Subcontractor Affidavit forms to the Department of Planning and Development at least two days before requesting their inspections. An HVAC rough inspection is performed to ensure the system is installed according to applicable code requirements, including ductwork, vents, appliance vents, thermostat wiring, and gas lines.
