01 / Plan path

Choose the right production starting point.

ADU and JADU permits are decided by the Community Development Director. The City reports a 60-day review period once an application is deemed complete.

Express PlanStarting at $4,500

For a qualifying jurisdiction preapproved plan adapted into the property-specific architectural production set.

Custom PlanStarting at $6,500

For an original floor plan and architectural production set developed around the property and homeowner.

02 / Size + fee checkpoints

Size affects more than floor area.

Coronado's Planning and Zoning Division administers the General Plan, Local Coastal Program and zoning ordinance together, so ADU standards are read alongside the Local Coastal Program.

Fees require confirmation with Community Development. The City publishes an ADU application handout that lists current submittal requirements.

03 / Site conditions

Property conditions can change the path.

  • Local Coastal Program consistency and whether a Coastal Development Permit is required
  • Zoning and lot configuration
  • Existing dwelling and utility records
  • Parking and access
04 / Consultant screen

Likely disciplines to evaluate.

  • Structural engineering
  • Title 24 energy documentation
  • Survey
  • Coastal consultation where the Local Coastal Program applies

Consultants are retained only when required by the property, design, or reviewing agency. Their proposals and coordination are separate from the architectural production fee unless stated otherwise in the agreement.
