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.

Orlando has a high HOA rate (78%) — do I need HOA approval for an ADU? +
Approximately 78% of Orlando properties are in HOA-governed communities. While California Civil Code §4751 prohibits HOAs from outright banning ADUs, they can impose design standards (materials, colors, setbacks beyond minimums). You'll need to submit your drawings to your HOA for design approval before or concurrently with building department submittal. Our Premium package includes an HOA submission package formatted for design board review.
Does Orlando's seismic zone affect ADU construction requirements? +
Orlando falls within Seismic Design Category Seismic Design Category A (ASCE 7). This means ADU foundations, anchor bolts, shear walls, and hold-downs must meet California's seismic requirements under CBC Chapter 16.
