Do I need a permit for hvac replacement or installation in Baton Rouge?

Permit likely required

Most likely yes. Hvac replacement or installation usually requires a permit in Louisiana. Confirm the specifics with Baton Rouge.

Mechanical work, including air conditioning and heating, worth $10,000 or more requires an LSLBC Mechanical classification (La. R.S. 37:2150.1); this is a licensing rule, not a permit exemption. The International Mechanical Code and the IRC mechanical chapters are part of the statewide code; permit requirements for equipment change-outs are set by the parish or municipal office. Louisiana amendments require duct leakage testing to be done by individuals certified by a nationally recognized organization (LAC 17:I.107, amended N1103.3.5).
