What's Required in New Orleans

  • Building permit required for all wood decks and landings.
  • Structural plans showing footing size and framing details.
  • Must meet flood elevation requirements (Elevation Certificate).
  • Handrails required for all decks with more than 3 steps.
  • Guardrails must be at least 36 inches high for raised decks.
  • All wood must be pressure-treated or rot-resistant.

When a Deck Needs a Permit in New Orleans

Whether a deck needs a building permit in New Orleans usually comes down to how high and how big it is. Low, ground-level platforms are often exempt, while raised decks need a permit — many cities draw the line at decks more than about 30 inches above grade (where guardrails and footings come into play), but New Orleans’s exact threshold is set by the Department of Safety and Permits. Attached decks almost always require a permit because they tie into the house’s structure, and even a freestanding deck usually needs one once it passes the size or height cutoff. Check the requirements above before you build, and note that zoning setbacks from property lines apply regardless.

Do You Need a Permit to Repair or Replace a Deck in New Orleans

It depends on how much you’re changing. Swapping worn decking boards or railing on the same layout is usually treated as maintenance and often doesn’t require a permit in New Orleans. But replacing the structural framing (joists, beams, posts, or footings), rebuilding the deck, enlarging it, or changing its height generally does — at that point it’s regulated like new construction. When in doubt, describe the scope to the Department of Safety and Permits before starting; the requirements above outline what New Orleans expects.
