ADU (Accessory Dwelling Unit) permit in Cape Coral, FL
Yes — you need a permit for adu (accessory dwelling unit) work in Cape Coral.
Building an accessory dwelling unit (garage apartment, casita, or detached unit) requires a building permit and zoning approval. An ADU is a new residential dwelling unit; the adopted Florida Building Code governs all construction and erection of structures and its exempt list has no Building category, so a new dwelling unit is never permit-exempt. The city fee code recognizes 'permitted and approved accessory dwelling units,' and new residential units are also subject to mobility/impact fees.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Cape Coral building department.
- Pay the permit fee when the permit is issued. Work done before that isn't covered.
- Book each inspection listed on the permit as the job reaches that stage.
Either of you can pull it. When a contractor does the work, it is normally their job.
If you skip it
Cape Coral's code doesn't set a specific fine for this work. In practice the department can issue a stop-work order, and unpermitted work tends to surface during a sale, when the buyer's inspector or the title company asks for it.
