How did Florida's Live Local Act affect ADU investment?
The 2023 Live Local Act and 2024 amendments streamlined approvals for housing projects near commercial corridors and encouraged cities to adopt more ADU-friendly zoning. Several Florida cities have independently updated their ADU ordinances in response, making more properties ADU-eligible.
How much extra does hurricane construction add to ADU costs in Florida?
