Deck Permit in Baton Rouge, Louisiana
It depends
Sometimes, depending on the project
Before building a deck of 200 square feet or more, or any deck raised 30 inches or more above the ground.
By Mario Bailey, verified against official sources
Quick answer
The city-parish permit and inspection division exempts decks that are under 200 square feet AND less than 30 inches off the ground AND located in a buildable area of the lot. All three conditions have to hold, so a small but elevated deck, or a low deck that sits outside the buildable area, still needs a permit. Deck work that alters the house's egress path, such as new stairs, handrails or guardrails, is separately listed as requiring a permit.
Typical threshold: deck floor area; the exemption also requires the deck to be less than 30 inches off the ground and located in a buildable area of the lot.

How to apply in Baton Rouge
A residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- A permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- A scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- A deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- A section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

Inspections and closing out your permit
Deck work is inspected in sequence as it is built: the footings before concrete is placed, the framing before the decking boards go down, and a final inspection once the deck is complete. Each stage checks the items that would be hidden or unsafe if missed.
- Footing or pier inspection: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).
- Framing inspection: after the deck is framed but before the decking conceals it, the inspector verifies the ledger attachment and its flashing, the fastener and bolt schedule, joist hangers and metal connectors, post-to-beam and post-to-footing connections, and the lateral load connection; call it before decking is installed (IRC R109.1.4 frame inspection; R507.9 ledger and flashing).
- Final inspection: after the deck is complete and before it is used, the inspector confirms guard height and opening limits (a 4 inch sphere must not pass, 4 3/8 inch at stairs), stair riser and tread dimensions, handrail height and graspability where there are 4 or more risers, stair landings, and required stair lighting (IRC R109.1.6 final inspection; R312 guards, R311.7 stairs and handrails).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Baton Rouge permit portal or by phone at 225-389-3205.

- Under Louisiana law (La. R.S. 37:2157(A)(2), (A)(13), (A)(15)(a), (B); La. R.S. 37:2160(B) and (C)): Yes. R.S. 37:2157(A)(13) exempts an owner who supervises or takes charge of construction, alteration or repair of his own personal residence from the contractor licensing law, but caps the exemption at one residence per year, with the year running from the date the certificate of occupancy issues; the cap lifts only where a change in the owner's legal marital status, or a change in employment forcing a move more than 50 miles from his residence, requires a second home. A separate exemption at R.S. 37:2157(A)(2) covers an owner who takes charge of work on his own property for his own use, where the result will not be for sale or rent and the owner controls access. A residential property owner who physically performs home improvement work on his own residence is also exempt from home improvement licensure under R.S. 37:2157(A)(15)(a). The exemption is not self-executing at the permit counter: R.S. 37:2157(A)(13) requires an affidavit of exemption on a board form in order to obtain the building permit, and R.S. 37:2160(C) obliges the local permit official to collect that affidavit before the permit issues. R.S. 37:2157(B) adds that none of these exemptions waives local or state health and life safety code requirements, so an exempt homeowner still owes the permit and the inspections. Confirm how Baton Rouge applies this before you apply.
