HOUSING/MANUFACTURED: Provides relative to manufactured and modular housing in flood-prone areas
HB 318 requires manufactured and modular homes in flood-prone areas to comply with FEMA’s installation manual for foundations. It allows local governments to adopt stricter elevation requirements (called "freeboard") than FEMA’s minimums, as long as these higher standards are uniformly applied based on current flood maps. The bill mandates that all building permits must include the site’s Base Flood Elevation and required finished floor elevation, including any extra freeboard. This directly affects home installers, local building departments, and homeowners in flood zones by standardizing flood safety requirements.

MINOR
This bill updates Louisiana law regarding manufactured and modular housing in flood-prone areas. It clarifies that foundations must meet specific FEMA guidelines and explicitly allows local governments to adopt stricter elevation or freeboard requirements to encourage higher safety standards. Additionally, it mandates that building permits must clearly display the Base Flood Elevation and required finished floor elevation to ensure transparency for homeowners.
Scope change
The bill maintains the existing scope but clarifies the relationship between state minimum standards and local stricter regulations, shifting from a prohibition on stricter rules to an encouragement of them.
REQUIREMENT
Changed the rule on local regulations from prohibiting stricter standards to explicitly allowing them, provided they incentivize going above minimum floodplain management standards.
Added a specific requirement that all building permits must include the Base Flood Elevation and the required finished floor elevation based on current maps.
DEFINITION
Clarified that the Base Flood Elevation must be based on the currently adopted Flood Insurance Rate Map and cannot vary based on alternative or superseded sources.
