MO SB1774

Local governments in Missouri are prohibited from banning modular homes or qualified manufactured homes in residential zones where single-family housing is permitted, and cannot impose more restrictive requirements than those applied to site-built homes

Qualified manufactured homes must meet specific criteria: manufactured within 5 years of installation, at least 20 feet wide or two stories tall, minimum 900 square feet living area, affixed to a permanent foundation with masonry enclosure, and built to federal HUD standards

Local governments may adopt compatibility standards for manufactured housing placement, but these standards cannot be more stringent than those applied to other single-family residences in the same zone

Any zoning regulation violating these provisions is declared void and unenforceable; historic property protections and private homeowner association requirements remain permissible

Includes an emergency clause making the law effective immediately upon passage due to the stated urgent need for fair zoning regulations for manufactured housing
