Orlando has relatively reasonable ADU regulations compared to other Florida cities, allowing detached units in residential zones. The city's rapid growth has prompted more liberal ADU policies to address housing demand.
Zoning & Size Requirements [1][2]
Yes, you can build an ADU in Orlando. A detached ADU can be up to 1,000 sq ft under current Florida and Orlando zoning rules.

What's Changed Recently
- Florida SB 48 (2026 session): statewide ADU mandate passed the Senate 38-0 (Feb 2026) but died in the House on the final day of session (Mar 13, 2026) over a short-term-rental dispute — local rules still govern; reform widely expected to return in 2027
- City of Orlando does not require owner-occupancy — owners may build an ADU and rent both units long-term (Chapter 58, Part 3A)
- ADUs capped at 1,000 sq ft (min 500 sq ft) and must be smaller than the principal structure
- Unincorporated Orange County (Chapter 38) still requires the owner to live on the parcel
