The apartment fire-separation rule, carried forward

“C. All unsprinkled dwelling units within apartment buildings shall be separated from one another by construction having a fire resistance rating of not less than one hour as required by the standard building code.”

Worth knowing when an association is converting, subdividing or reconfiguring units in an unsprinklered multi-unit building.

The owner duty in §307 that boards keep missing

“§307. Observation of Construction; Final Inspection A. For a structure which by law may only be constructed with plans prepared and certified by a licensed architect, or licensed civil engineer where permitted, it shall be the duty of the owner of such a structure to provide for periodic observation of the construction of the structure to determine if the work is proceeding in accordance with the plans and specifications as approved by the fire marshal. The observations shall be performed by a registered architect, or a registered civil engineer where permitted.”

Read the subject of that sentence: “it shall be the duty of the owner.” Where architect-certified plans were required, the association — not the contractor, and not the design professional as a matter of course — has to arrange periodic professional observation. That is a line item in a renovation budget that is easy to leave out and awkward to add later.

How this sits with the association's own architectural review

Three independent gates, and clearing one clears none of the others.

• The architectural committee. Its authority comes from the declaration, and since January 2026 from the Planned Community Act — including R.S. 9:1141.37(C), which requires the board to establish procedures for approving construction applications “including a reasonable time within which the board of directors shall act after an application is submitted and the consequences of its failure to act.”
• Fire Marshal plan review. Required with the building-permit application for everything but one- and two-family dwellings.
• The local building permit. Which the rule conditions on proof of Fire Marshal approval.

The Fourth Circuit made the same point from the other direction in 2025. In Lake Terrace Property Owners Association v. City of New Orleans, Board of Zoning Adjustments, No. 2024-CA-0577 c/w 0758 (La. App. 4 Cir. 2/18/2025), the City's permit director had granted a rear pool cabana “Established Two-Family Dwelling” status in a single-family subdivision and issued a renovation permit including a new kitchen. The association appealed, lost before the Board of Zoning Adjustments on a 3-vote motion where the ordinance required “[t]he concurring vote of four (4) members,” and won on judicial review:

“As such, based on the overwhelming evidence in the record that established the rear structure was not a separate dwelling unit from the principal structure, we find the BZA's failure to approve the appeal and overturn the Director's decision was arbitrary and capricious.”

A lawful city permit did not settle the question. Whether a writ application followed is not established.²

One thing to note about the agency's own website

The Fire Marshal's public “Codes, Rules & Laws” page still recites the pre-amendment standard — the “As of July 1, 2017 … 2015 Edition of the NFPA 101” language. The agency's web page is behind its own rule. Work from the Register text, not the website.

What a board can do

• Ask which code edition the design is drawn to. The rule points at “the most recently adopted and amended” LSUCC, which is a moving target — see the proposed 2027 adoption of the 2024 I-Codes.
• Budget the §307 observation. Where architect-certified plans are required, it is the owner's duty.
• Do not treat a permit as covenant compliance, or vice versa. The two reviews are independent, and Lake Terrace is what it looks like when they diverge.
• Fix the paperwork order. Proof of Fire Marshal approval goes with the permit application, so the design has to be final before the permit is sought.

What to watch next

The companion Rule at page 1390 of the same August 2026 Register, which amended LAC 55:V.103, 105 and 107 to add the LSUCC and the International Fire Code to the materials the Fire Marshal uses. And the proposed wholesale adoption of the 2024 I-Codes and 2023 National Electrical Code, effective January 1, 2027, which would change what “the most recently adopted and amended LSUCC” means.
