STATE GA Conditioned AirClass I or II
HVAC contractors operating in Marietta, Georgia, must navigate a dual-layer regulatory environment. At the state level, the Georgia Construction Industry Licensing Board mandates that all conditioned air contractors hold a valid Class I or II license. This state license serves as the foundation for your ability to legally perform mechanical work across the state.
Locally, the City of Marietta requires contractors to register their business and secure mechanical permits for individual projects. Compliance involves ensuring that all installations meet the International Mechanical Code (IMC) as adopted by the state and local amendments. Failure to secure proper permits or schedule inspections can lead to stop-work orders and potential fines, making it essential to coordinate closely with the Marietta Development Services Department before beginning any installation.
