Property Eligibility
Is My Bonita Springs, FL Property Eligible for an ADU?

Single-Family Home
Permitted on single-family lots in Bonita Springs under California state law. No owner-occupancy requirement in Bonita Springs — 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 75% of Bonita Springs 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.
Coastal Zone Properties
Properties within Bonita Springs's Coastal Overlay Zone require a Coastal Development Permit (CDP) in addition to standard building permits. This adds 2–6 months to the timeline. Our drawings flag coastal requirements and meet both local and Coastal Commission standards.
