What are the key ADU regulations in Coronado?

Coronado has well-defined ADU regulations designed to maintain the city’s character while allowing homeowners to expand their living spaces. Here’s what you need to know:

• Maximum ADU Sizes: Detached ADUs can be up to 850 sq. ft. for one-bedroom units and 1,000 sq. ft. for ADUs with two or more bedrooms. Attached ADUs follow the same size limits but must not exceed 50% of the primary home’s square footage.
• Setbacks: ADUs must maintain a minimum 4-foot setback from rear and side property lines.
• Two-Story ADUs: Not permitted in Coronado. ADUs must adhere to a 16-foot height limit, ensuring they integrate with neighborhood aesthetics.
• Building Separation: A minimum 10-foot distance is required between a detached ADU and the main home.
• Permit Timeline: Coronado processes ADU permits within 60 days, but projects in coastal zones or with unique site constraints may take longer.
• Coastal Zone Compliance: Properties in The Shores, Bayside & Ferry Landing, and Silver Strand may require Coastal Development Permits. We handle all necessary approvals to keep your project on track.
