Saratoga

The City of Saratoga permits ADUs across most residential zones. Saratoga follows both state and local ADU laws, allowing most single-family homes to build one detached ADU and one Junior ADU (JADU) per lot. Multi-family properties may be eligible for multiple ADUs, depending on site conditions.

Saratoga aligns with California’s broader ADU legislation but has its own requirements for height, setbacks, and design review.

• Detached ADU: A standalone unit in the backyard
• Attached ADU: A unit built as an addition attached to the main residence
• Conversion ADU: Created by converting an existing garage, basement, or internal space of the home
• Junior ADU (JADU): must be located within the walls of the existing or proposed home and are limited to 500 square feet.

• Maximum Size:
  
  • Detached: Up to 1,200 sq ft
  • Attached: can be up to 1,200 square feet, or 50 percent of the main home’s living area, whichever is less. They can be as tall as the primary home, up to a maximum of 25 feet.
    
• Setbacks:
  
  • Rear and side setbacks no less than 4 ft
• Height Limits:
  
  • Standard height is 16 feet, but can be up to 24 feet depending on the unit type and location.
    
• Parking Requirements:
  
  • Additional parking is not required if the ADU is:
    
    • Within half a mile of public transit
    • Converted from an existing structure
    • Located in a historic district or designated area

To build an ADU in Saratoga, the following approvals are typically required:

• Zoning compliance review to ensure the ADU meets Saratoga’s residential zoning and setback requirements
• Site plan and elevations showing the location, size, and design of the ADU relative to the main dwelling and property lines
• Architectural drawings illustrating exterior materials, color, and design consistent with the main home
• Structural calculations and engineering for new construction or modifications to existing structures
• Title 24 energy documentation demonstrating compliance with California energy efficiency standards
• Permit submission through the City of Saratoga’s online or in-person permit portal
  

Homeowners should also review Saratoga’s current fee schedule, impact fee exemptions for ADUs under 700 sq. ft., utility connection requirements, and fire code compliance.

Permit review times in Saratoga typically range from 6 to 12 weeks, depending on project complexity and city workload. Projects requiring corrections may take longer. Engaging professionals familiar with Saratoga’s ADU process can help streamline approval.
