General ADU Zoning Information

In Coronado, properties designated for both single-family and multi-family purposes might meet the criteria necessary for the construction of Accessory Dwelling Units (ADUs).

It is essential to consult the specific ADU zoning regulations applicable to your jurisdiction to ensure compliance. ADU zoning regulations typically address factors such as ADU size, setback requirements, height specifications, and other relevant guidelines. By understanding and adhering to the appropriate zoning regulations, property owners can determine the feasibility and eligibility of constructing ADUs on their designated properties, promoting informed decision-making in the pursuit of additional dwelling unit development.
