Creates new provisions for zoning regulations for manufactured housing

HB 3230 prohibits local governments from banning manufactured homes in residential zones where other single-family homes are allowed or imposing stricter rules on them than on traditional homes (e.g., lot size, foundation, or appearance). It defines "qualified manufactured homes" as those built within five years, meeting federal safety standards, having a minimum 900 sq ft living area, a 20-foot width or two-story height, and a masonry foundation. The bill requires local zoning rules for these homes to match those for standard homes and voids any discriminatory regulations. It directly affects manufactured home owners and local governments enforcing zoning laws in Missouri.
