Florida ADUs in 2026: What Homeowners Should Expect in the New Year

Accessory Dwelling Units, or ADUs, are becoming a popular choice for Florida homeowners. Also called granny flats, casitas, or backyard cottages, these small homes on your property can add value, provide rental income, or give family members their own space.

As we enter 2026, Florida ADU rules are evolving. Here’s what homeowners need to know before building their ADU next year.

State Law and Proposed Changes for ADUs

Florida has been moving toward making ADUs easier to add, but a fully statewide requirement is not yet in effect. Currently, state law allows local governments to permit ADUs on single-family lots, but each city or county decides its own rules. Some areas already make it simple to build an ADU, while others still have restrictions.

Several recent bills—like SB 48 for 2026—aim to require all local governments to allow ADUs in single-family residential zones. If passed, these laws would give homeowners more consistent opportunities across the state. Until then, rules still vary, so it’s important to check local zoning codes before planning an ADU.

What Homeowners Can Expect in 2026

More Local Options to Build

While the statewide mandate is still proposed, many local governments are already updating their codes to allow ADUs. By the end of 2026, more cities and counties may have clearer rules and options for homeowners.

Easier Renting in Some Areas

Some local jurisdictions are simplifying rules for parking, owner-occupancy, and other requirements. These updates make it easier to rent out ADUs long-term, but regulations still vary by city.

Taxes Stay Favorable

Adding an ADU generally doesn’t affect your homestead tax exemption. If you rent the unit, it may be assessed separately for taxes, but your main home’s exemption is protected.

Local Rules Still Matter

Even with proposed statewide reforms, local regulations are key. Cities and counties may control:

• Maximum size of the ADU
• Setbacks from property lines
• Parking requirements
• Design or appearance standards
• Permitting timelines and fees

Homeowners associations (HOAs) may also have rules restricting ADUs. Always check city codes and HOA rules before starting a project.

Key ADU Trends in Florida for 2026

• Rising Investment Interest: Many homeowners are building ADUs to earn extra income. In cities like Tampa and Orlando, rental demand is strong.
• Multigenerational Living: ADUs are ideal for parents, adult children, or guests who need private living space.
• Faster Permits in Some Cities: Certain municipalities are improving permitting systems, making construction timelines shorter and simpler.

How to Get Ready for Your ADU

Here are practical steps to take before building:

1. Check Local Zoning: Confirm your property allows an ADU.
2. Review HOA Rules: Make sure your community permits ADUs.
3. Estimate Costs & Timeline: Know your permitting fees and approval times.
4. Plan Utilities & Access: Think about electricity, water, and construction access.
5. Consult Experts: ADU builders or designers can help avoid mistakes and save time.

2026 is shaping up to be a significant year for Florida ADUs. While a fully statewide requirement is still proposed, many local governments are updating their rules, making it easier for homeowners to plan and build ADUs.
