Do I need a permit for basement finishing in Unincorporated St. Martin Parish?

Permit likely required

Most likely yes. Basement finishing usually requires a permit in Louisiana. Confirm the specifics with Unincorporated St. Martin Parish.

There is no statewide list of basement work exempt from permits; the IRC's administrative part is not adopted (LAC 17:I.107), and the parish or municipal office decides based on the scope. For energy code purposes all of Louisiana is climate zone 2A (LAC 17:I.107, amended N1101.7). Home improvement work worth $7,500 or more needs an LSLBC home improvement registration or residential license unless the owner physically does the work on their own residence, and electrical, mechanical, or plumbing contracting of $10,000 or more needs the matching classification (La. R.S. 37:2150.1 and 37:2157(A)(15)).
