Florida’s New ADU Law (2026) & What Homeowners Need to Know

Accessory Dwelling Units are now permitted “by right” on single-family lots. Here’s what that means for you.

What Changed?
As of July 1, 2026, Florida law requires cities and counties to allow ADUs on single-family properties without special hearings or variances.

Local governments must comply by December 1, 2026.

Translation: It’s much easier to build a guest house or in-law suite on your property.

What Is an ADU?
An ADU (Accessory Dwelling Unit) is:

  • A detached guest house
  • An in-law suite
  • A garage apartment
  • A backyard rental unit

It includes its own:

  • Kitchen
  • Bathroom
  • Sleeping area

Why This Law Matters To YOU

✔ Housing Flexibility

For aging parents, adult children, or long-term guests.

✔ Rental Income

You can rent the unit (30+ days) under state law.

✔ Increased Property Value

Additional livable square footage increases market appeal.

✔ Homestead Protection

Renting an ADU does not automatically eliminate your homestead exemption.

What Has NOT Changed

Very important. Local municipalities can still regulate:

  • Setbacks
  • Parking requirements
  • Design standards
  • Utility connections

What This Means for Central Florida Homeowners

Zoning still matters.
Lot size matters.
Utility access matters.

Every property is different.

That’s why planning correctly from the beginning is critical. Sunshine State Construction & Design works with homeowners throughout Central Florida to design and build code-compliant in-law suites, guest houses, and detached ADUs.

From feasibility review to permitting to construction, we guide the entire process.

Thinking About Building an ADU? Before you start drawing plans, you need to know:

  • Is your lot eligible?
  • What size can you build?
  • What will it cost?
  • What are the city-specific requirements?

Schedule a consultation to review your property and options.
