Can you build a PSL Modular unit in Mississippi?

The State Fire Marshal's Office, within the Mississippi Insurance Department's Factory-Built Home Division. Authority dates to the 1970 Factory-Built Homes Law (and Title 75, Chapter 49). The state handles modular plan review (about $400 per floor plan) and licenses retailers, transporters, and installers; units are factory-inspected before delivery. Your local jurisdiction permits the site work — foundation, utilities, zoning.

Only where local zoning permits — Mississippi has some of the more restrictive zoning in the country, and there's no statewide ADU law. That said, cities are opening up: Clinton's 2025 ordinance allows attached and detached ADUs, with detached units up to 1,500 sq ft on lots over 10,000 sq ft (capped at 50% of the main home, 14 ft single-story, 10 ft rear / 5 ft side setbacks). Jackson and many coastal municipalities have clearer processes. Confirm your specific city/county.

A great deal. After Hurricane Katrina, the Gulf Coast (Biloxi, Gulfport, Bay St. Louis) enforces strict wind-load and flood-elevation standards — high design wind speeds and elevation to base flood (typically pilings). The unit must be engineered to coastal wind and elevated, or it can't be insured. PSL Modular configures the wind rating and elevation into the factory order for coastal Mississippi.

Inland (Jackson, the Delta, north Mississippi) the drivers are tornado/high wind and summer heat — a robust structure and an efficient thermal envelope, with effectively no snow. Far-northwest Mississippi is also near the New Madrid seismic influence. PSL Modular sets the spec from your site.

Yes. The Gulf Coast is a rental and tourism market that rewards fast, coastal-rated construction, and inland workforce demand (manufacturing, logistics) suits multi-unit modular. The state-inspected unit clears the building; your work is local zoning and (on the coast) wind/flood.
