At Goshen Tiny Homes, we help you navigate these ADU zoning regulations with expertise and confidence, ensuring your project meets all local requirements from permit application to final approval.

Are ADUs Legal in Florida?

Yes, accessory dwelling units are permitted throughout most of Florida, thanks to supportive state legislation. Florida Statute 163.31771 encourages local governments to adopt ordinances allowing ADUs in single-family residential areas, particularly to increase affordable housing options for elderly persons and individuals with low to moderate income.

However, the specific ADU regulations by city and county determine whether you can build on your property and what requirements you must meet. Some jurisdictions have embraced ADUs with streamlined processes, while others maintain more restrictive rules. That’s why understanding your local ADU zoning regulations is the critical first step in your project.

What Qualifies as an ADU Under Florida Law?

According to Florida statutes, an accessory dwelling unit is a secondary residential structure that includes its own kitchen, bathroom, and sleeping area. It can be:

  • Detached: A separate, standalone building in your backyard
  • Attached: Connected to your primary residence
  • Internal: Created within the existing main home
  • Above-Garage: Built as a living space over a garage structure

 

At Goshen Tiny Homes, we specialize in detached ADUs—standalone units built on concrete slab foundations with block construction designed specifically for Florida’s climate and building codes. These structures must comply with local ADU regulations regarding size, setbacks, and placement.

Key ADU Zoning Regulations in Florida

Size Requirements
Most Florida jurisdictions require a minimum ADU size of 400 square feet. Maximum size is typically calculated as a percentage of your primary dwelling—often 25% to 50% of the main home's square footage. Your ADU cannot be larger than your primary residence in any Florida jurisdiction.
Setback Requirements
ADUs generally must be positioned at least 10 feet from the primary dwelling and maintain specific distances from property lines—typically 5 to 10 feet from side and rear boundaries. Front setbacks usually match requirements for primary structures in your zoning district.
Lot Coverage
Total building coverage, including your main home and ADU, typically cannot exceed 35-50% of your lot size, depending on your local ADU zoning regulations.
Parking Requirements
Most areas require at least one additional parking space for the ADU, though some jurisdictions waive this requirement if the property is near public transportation or in urban centers.
Owner Occupancy
Some municipalities require the property owner to live in either the main home or the ADU, though this restriction is becoming less common as Florida embraces ADUs as a housing solution.
Utility Connections
ADUs must connect to existing water, sewer, and electrical systems. Separate utility meters may be required or optional, depending on local regulations.

Permits Required for ADUs in Florida

Building permits are mandatory for ADU construction throughout Florida. The specific permits needed depend on your jurisdiction and project scope:

Common ADU Permits:

  • Zoning approval or variance (if needed)
  • Building permit for new construction
  • Electrical permit for wiring and panel upgrades
  • Plumbing permit for water and sewer connections
  • Mechanical permit for HVAC installation
  • Site development or land use permit
  • Final occupancy permit after inspection

 

Some municipalities have created dedicated ADU permit processes that consolidate these requirements, while others require navigating standard residential construction permitting. Understanding local ADU regulations around permitting timelines—which can range from 4 weeks to 6 months—is essential for project planning.

At Goshen Tiny Homes, we handle the permit process as part of our turnkey service, working with local officials to secure all necessary approvals efficiently.
