Florida's Live Local 4.0 passed the legislature on March 13, 2026, with near-unanimous support. The update expands workforce housing rules, allows developers to sue cities that block affordable projects, and tightens tax-exemption opt-outs. What didn't make it? The controversial ADU and short-term rental provisions nearly killed the bill.
Key Takeaways
-
HB 1389 passed the House 98-4 and the Senate 35-0, becoming law on July 1, 2026, unless signed earlier or vetoed.
-
The bill adds fair housing protections, allowing developers to sue local governments that discriminate against affordable housing projects.
-
Lawmakers dropped ADU provisions after the House and Senate could not agree on whether cities could ban backyard units from being used as short-term rentals.
The original Live Local Act was passed in 2023 as one of the most aggressive state-level housing affordability laws in the country. It allows housing development on certain commercial and mixed-use properties, preempts local zoning that blocks workforce housing, and offers property tax incentives for qualifying projects.
As we covered in Live Local Act Florida updates, these changes have opened new possibilities for South Florida developers. Live Local 4.0 is the fourth consecutive year of proactive affordable housing policy from the state.
What did Live Local 4.0 change?
The update refines several key provisions of the original law:
Fair Housing Act amendment: Developers can now sue local governments that discriminate against affordable housing projects based on their financing structure or affordability designation. This closes a legal gap exposed when Coral Rock Development Group sued Pompano Beach for rejecting an affordable townhome project and lost on sovereign immunity grounds.
Tax exemption vesting: The vesting point for property tax exemptions now occurs at the building permit, easing lender concerns about political risk.
Tighter opt-out rules: Local governments must now show a three-year affordable housing surplus to opt out of the tax exemption program. Most counties must stay in.
Expanded scope: The law now applies to properties over 3 acres owned by religious institutions with a house of worship for at least a decade, plus land owned by counties, municipalities, and school districts.
Exclusions added: The bill excludes open space districts, areas of critical state concern, properties with conservation easements, and the Florida wildlife corridor.
Why does the right to sue cities matter?
As Larry Mastropieri explained on the Discover South Florida Podcast: "I have some sympathy for people who say the city wronged me, and I can't do anything about it. You can't really sue a city. I think you should be able to. The problem is that you get all the goons who shouldn't be suing, suing. There's a balance here."
The new provision creates that balance. Cities that use zoning delays to block qualifying affordable housing projects now face real legal exposure.

Why did the ADU provisions get dropped?
The most controversial part of Live Local 4.0 never made it into the final bill. Both chambers agreed that cities should be required to allow accessory dwelling units (backyard cottages, garage apartments, in-law suites) on single-family lots without special permits or hearings. They could not agree on one thing: whether those units could be used as short-term rentals.
The Senate wanted to let cities ban ADUs from being listed on Airbnb or VRBO. The House did not, citing a 2011 law under Governor Rick Scott that already limits local governments from banning short-term rentals outright.
The concern driving the Senate position was clear. During the pandemic, a wave of Florida homes were converted to short-term rentals, reducing long-term supply and pushing rents higher. Allowing new ADUs to become Airbnbs could repeat that pattern. Rather than let the dispute sink the entire bill, lawmakers dropped the ADU provisions entirely.
What does this mean for homeowners who want to build ADUs?
If you were hoping for a statewide right to build a backyard unit, that did not happen this session. As we explored in How Granny Flats Laws Are Reshaping Florida Housing, the rules vary widely by municipality. Local rules still apply. Some Florida cities already allow ADUs with conditions. Others make it difficult or impossible. Without state preemption, homeowners remain subject to whatever their municipality decides.
Larry offered some perspective on the practical reality: "It's not cheap to build stuff in South Florida. So if you're going to build an ADU, like an actual separate additional dwelling unit kind of disconnected from the house in your backyard, which by the way a lot of homes in South Florida the lots are too small to even do, the cost associated with building it and the debt you'd have to take, most people would just go buy another property. From an investor perspective, it's not easy to make anything make sense in South Florida. But to give people the opportunity to do it should be okay."
The issue is not dead. Expect lawmakers to revisit ADUs in future sessions once they find a compromise on the short-term rental question.
What does this mean for South Florida buyers and investors?
Palm Beach and Broward counties stand to benefit directly from the updated law.
More supply near transit: As we covered in South Florida real estate booms along Brightline, projects near stations in Boca Raton, Delray Beach, Boynton Beach, and Fort Lauderdale can now move forward with fewer zoning obstacles.
Developers have teeth: The fair housing amendment means cities cannot easily use design review, traffic studies, or other discretionary processes to slow down affordable housing without legal risk.
Tax exemptions are locked in: The tighter opt-out rules mean most counties cannot easily exit the program, giving developers more certainty on project economics.
More than 180 projects have been proposed under Live Local since 2023, including Seacrest Sound Apartments in Boynton Beach. The 4.0 update is designed to move more of them from proposal to construction.
