Bill > SB5249

This bill addresses the siting of kit homes, which are small prefabricated residential structures (800 square feet or smaller) that are assembled on-site, with the primary goal of providing emergency housing. The legislation allows cities and counties to permit kit homes in residential zones and other limited development spaces, with specific provisions to ensure housing safety and quality. Municipalities and counties must adopt an ordinance establishing a process to inspect these kit homes at least every five years to verify they meet sufficient life, health, and safety standards. This bill modifies existing zoning laws to eliminate minimum gross floor area requirements for single-family dwellings and specifically enables local governments to use kit homes as a flexible housing solution. The legislation provides local jurisdictions with more discretion in addressing housing needs, particularly for emergency housing situations, by creating a standardized framework for deploying these compact, prefabricated residential structures while maintaining safety and quality standards through regular inspections.
