Overview

Georgia requires permits for all HVAC work under the Georgia State Minimum Standard Codes. Homeowners may apply as owner-builders for their primary residence by signing an affidavit. Georgia has relatively straightforward permitting processes in most counties, though Atlanta (Fulton County) uses a valuation-based fee schedule that can be higher than other Georgia jurisdictions.

Like most states, Georgia requires a mechanical permit for HVAC replacements and installations. The specific rules for fees, homeowner permits, and application processes vary by county and city — always confirm with your local building department before beginning any HVAC project.
