Do I need a permit for deck construction or replacement in Unincorporated St. Landry Parish?

Permit likely required

Most likely yes. Deck construction or replacement usually requires a permit in Louisiana. Confirm the specifics with Unincorporated St. Landry Parish.

Louisiana adopts the IRC without its administrative part (LAC 17:I.107), so the IRC's list of work exempt from permits, including small low decks, does not apply statewide; the parish or municipal office decides. State law bars local enforcement of the code on a detached residential accessory structure of 200 square feet or less in footprint, except where the ultimate design wind speed is 130 mph or more in hurricane-prone regions and in municipalities over 45,000 people (La. R.S. 37:3738(B)); an attached deck does not qualify. Deck work on an existing home worth $7,500 or more needs an LSLBC home improvement registration or residential license, and a home improvement registrant may not do structural work such as footings (La. R.S. 37:2150.1).
