Understanding ADU regulations is essential before building your accessory dwelling unit in Florida. While state law encourages ADU development, the specific rules governing size, placement, and permits vary significantly across Florida’s 67 counties and individual municipalities. 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.
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.
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.
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:
A separate, standalone building in your backyard
Connected to your primary residence
Created within the existing main home
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.
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.
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.
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.
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.
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.
ADUs must connect to existing water, sewer, and electrical systems. Separate utility meters may be required or optional, depending on local regulations.
Building permits are mandatory for ADU construction throughout Florida. The specific permits needed depend on your jurisdiction and project scope:
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.
