Building Code
2021 IRC / 2021 IBC (Louisiana adoption, effective January 1, 2023)
Freestanding decks not more than 30 inches above grade are exempt per IRC R105.2.
If your deck does NOT meet all exemption criteria, you must obtain a permit before construction. Building without a required permit can result in fines, stop-work orders, and required demolition.
Review the exemption criteria above. If your deck exceeds any threshold, a permit is required.
You'll need a site plan, deck dimensions, framing details, and footing specifications. Check Baton Rouge's specific documentation requirements.
Apply through MGO Connect Portal . Pay the permit fee at submission.
Once approved, post your permit visibly and schedule required inspections (typically footing, framing, and final).
