Our ADU experience in Coronado

Coronado’s ADU regulations are largely in line with state guidelines, allowing up to 1,000 square feet. With a smaller building department, regulation questions are answered swiftly. And while the entire city is in the coastal zone, ADUs do not require a separate CDP (meaning no added expense or time).
