Different name, same property question
People use different words for this kind of space. The important question is whether your property can legally and practically support it.
The address decides the next step
Jurisdiction, utilities, flood, access, setbacks, HOA/private rules, trees, drainage, and site layout can all change the answer.

Common questions about granny flats in Orange County
- Are granny flats legal in Orange County, Florida?
- Yes, granny flats — also called ADUs, accessory dwelling units, or in-law suites — are legal in Orange County under the current land development code, subject to lot size, setback, utility, and zoning requirements. Whether your specific property qualifies depends on the parcel, HOA restrictions, flood zone, and available utility connections. A property screen checks the public signals for your address before any plan spend.
- How big can a granny flat be in Orange County?
- Orange County has size limits for ADUs that vary based on the primary home size and lot coverage rules. Common limits cap detached ADUs around 1,000 sq ft or a percentage of the primary structure, though the exact limit depends on your zoning district. City jurisdictions like Winter Garden and Orlando have separate size rules. A property screen confirms which set of rules applies to your address.
- Do I need a permit for a granny flat in Orange County?
- Yes. A granny flat or detached ADU in Orange County requires building permits and approval from Orange County Development Services or the applicable city building department. You will also need to demonstrate compliance with setbacks, utility capacity, parking, and potentially impact fees. An address screen before hiring a builder or purchasing plans can identify likely blockers before you commit money.
