Do I need a permit for an HVAC changeout in Baton Rouge?

In most Louisiana jurisdictions, including Baton Rouge, a mechanical permit is required for equipment changeouts even when the replacement is like-for-like. Confirm with the Baton Rouge building department before starting work.

How long does a Baton Rouge permit take?

Over-the-counter trade permits such as mechanical, plumbing and re-roof are often issued the same day when the application is complete. Structural work that needs plan review takes longer. Complete, legible applications are the single biggest factor in same-day issuance.

Can RapidPermit Systems submit the Baton Rouge permit for me?

No. We produce the completed, print-ready application; you file it with the Baton Rouge building department and pay its fees.
