Can Granny Flats Be the Solution to Florida’s Affordable Housing Dilemma?

Accessory dwelling units—commonly called “granny flats”—are gaining serious traction as a practical lever in Florida’s ongoing struggle with affordable housing.

These units, which are basically small, self-contained residences built on existing single-family lots, are attractive because they offer a scalable way to optimize land use without requiring major new development.

The real upside here is flexibility. Florida’s housing demand is high, and ADUs let property owners diversify their offerings. Whether it’s a rental to generate extra income, a space for extended family, or a more affordable option for new homeowners, these smaller units fill gaps in the market that single-family homes simply can’t.

Recent legislative moves, like the Live Local Act, signal the state’s intent to streamline approval processes and override some restrictive local zoning. In theory, this should help accelerate ADU growth by cutting through red tape—though, as always, implementation depends on how quickly and thoroughly local governments adapt. If cities continue to cling to outdated parking requirements or overly stringent size restrictions, the real impact may be limited.

Still, ADUs aren’t a silver bullet. They’re one part of a broader, multi-pronged approach that Florida needs to address its housing shortage. With the right regulatory adjustments and policy support, granny flats could become a key component in stabilizing rents, expanding housing choices, and making homeownership more accessible for a wider range of residents. The business case for ADUs is strong—provided the state and localities follow through.
