Florida Law Bans Zoning Discrimination Against Factory-Built Homes

Florida has enacted a new law, effective July 1, 2024, that prohibits local governments from discriminating in their zoning and land use regulations against qualifying factory-built single-family homes. Section 553.385 of the Florida Statutes mandates that these "off-site constructed" homes must receive the same local zoning treatment as traditional site-built homes. This legislation aims to address a long-standing disparity where factory-built housing, despite meeting building codes and quality standards, has often faced more restrictive zoning, limiting where they can be placed and impacting housing affordability.

The law specifies that "off-site constructed" homes must meet certain criteria to qualify for equal treatment. These include being built in a factory in accordance with the Florida Building Code, intended for use as a single-family dwelling, and meeting all applicable federal, state, and local codes and standards. Crucially, the law preserves the ability of local governments to enforce neutral design and development standards. This means that while the *type* of construction (factory-built vs. site-built) cannot be a basis for discrimination, local authorities can still require that homes, regardless of their construction method, adhere to aesthetic guidelines, lot size requirements, setback rules, and other development standards that are applied uniformly to all housing types.

This legislative action is a significant step towards increasing housing supply and affordability in Florida, a state that has grappled with a severe housing shortage and rising costs. Factory-built homes, often referred to as manufactured homes when built to federal standards or modular homes when built to state building codes, can typically be constructed at a lower cost than traditional site-built homes due to efficiencies in factory production and reduced on-site labor. By removing discriminatory zoning barriers, the law is expected to encourage the development and sale of these homes, providing more options for residents, particularly first-time homebuyers and those with moderate incomes.

The passage of Section 553.385 follows years of advocacy from the manufactured housing industry and housing affordability advocates who have argued that outdated zoning ordinances have unfairly penalized factory-built homes. These ordinances often relegated factory-built housing to specific, less desirable areas or imposed requirements that made them unfeasible for many consumers. The new law aims to level the playing field, ensuring that these homes are judged on their merits and compliance with building codes, rather than by their method of construction. The preservation of neutral design standards is a key component, ensuring that local communities can maintain their character while embracing more diverse and affordable housing solutions.
