Can you build a PSL Modular unit in Louisiana?

The Office of the State Fire Marshal reviews plans for each industrialized building/module for compliance with the Louisiana State Uniform Construction Code (LSUCC); the plan review can be performed by the Fire Marshal or by a third-party provider registered with the LSUCCC, and registered third-party inspectors perform the construction inspections. With that done, your local jurisdiction permits the site work — foundation, elevation, utilities — without re-reviewing the structure.

Yes — New Orleans has well-defined ADU rules under its 2015 Comprehensive Zoning Ordinance. ADUs are permitted in most single-family residential districts (e.g., HU-RS, HU-RD1, HU-RD2). Detached ADUs generally need a minimum 5,000 sq ft lot, are capped at 1,200 sq ft or 75% of the primary dwelling, and many districts require owner-occupancy of one unit. Historic districts (HDLC / Vieux Carré) require a Certificate of Appropriateness. Permits run about $1,000-5,000 over 6-12 weeks.

Hurricanes and flood dominate. South Louisiana carries high coastal design wind speeds, and FEMA flood zones — much of the New Orleans area — require elevating to base flood, typically on pilings. The unit must be engineered to the wind load and elevated, or it can't be insured. PSL Modular configures the wind rating and elevation into the factory order.

No. ADUs are shaped at the city or parish level. New Orleans is the clearest example; other parishes and municipalities set their own rules. Confirm your specific jurisdiction.

Yes — New Orleans has a deep culture of secondary units (think shotgun doubles), and modular places a finished, elevated, hurricane-rated unit quickly. The state-reviewed unit clears the building; your work is the CZO/zoning, historic-district approvals where applicable, and flood elevation.
