Property Eligibility
Is My Orlando, FL Property Eligible for an ADU?
Orlando homeowners benefit from California's state ADU law — one of the most permissive frameworks in the country since 2020. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Orlando under California state law. No owner-occupancy requirement in Orlando — you can rent both units as investment properties. Ministerial permit approval — no neighbor input or discretionary design review.
Multi-Family Property
Up to 2 detached ADUs plus JADUs (Junior ADUs) within the existing main structure are permitted under California state law. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 78% of Orlando homes are in an HOA. California law (AB 670) prohibits HOAs from banning ADUs outright, but they can impose reasonable architectural standards. Our drawings include HOA submission formatting.
Historic Districts
Yes - in historic districts only (Certificate of Appropriateness required); Appearance Review may apply in Traditional City overlay or for corner lots
Always verify eligibility with Permitting Services Division before designing.
