St. Tammany Parish, LA Building Safety: Carbon Monoxide Detectors (2026)

St. Tammany Parish does not impose a stand-alone carbon monoxide detector mandate on ordinary owner-occupied homes, but it writes the requirement directly into the operating standards for short-term rentals in the unincorporated parish. Section 400-8(NN) of the Unified Development Code, the zoning-use standard for Short Term Rentals, requires that short term rentals meet all applicable building, health, fire, and related safety codes at all times, and specifically that an operable hardwired carbon monoxide detector be installed in individual guest rooms or adjacent hallways, alongside a hardwired smoke detector and an operable fire extinguisher.

00 non-refundable application fee. Section 22-591(b) requires the operator to submit a sworn affidavit certifying that they have read and understood the Section 400-8(NN) minimum standards, including the detector requirement, and will remain in compliance for the full permitting term. A complaint about a missing or inoperable detector goes to the Department of Planning and Development, which documents, reviews, and can act on it, potentially leading to permit suspension for a minimum of 60 days or revocation for a minimum of one year under Section 22-594, following a hearing before the Bureau of Administrative Adjudication.
