Building ADUs in San Carlos: A City That Embraces Smart Growth

San Carlos, California, often called the "City of Good Living," is a vibrant Peninsula community in San Mateo County that has embraced accessory dwelling units (ADUs) as a practical solution to the Bay Area's ongoing housing challenges. With its desirable location between San Francisco and Silicon Valley, San Carlos has seen strong demand for ADUs as homeowners look to add rental income, house family members, or increase property value. Working with experienced ADU contractors in San Carlos is essential to navigating the city's specific planning requirements and making the most of your investment.

San Carlos ADU Regulations and Permitting Requirements

San Carlos follows California state ADU law while also maintaining its own local guidelines through the Community Development Department. Homeowners and ADU builders in San Carlos must be aware of the following key regulations:

  • Detached ADUs can be up to 1,200 square feet, depending on lot size and zoning.
  • Attached ADUs are generally limited to 50% of the primary dwelling's square footage.
  • Junior ADUs (JADUs) are capped at 500 square feet and must be within the existing structure.
  • Setback requirements typically require a minimum of 4 feet from rear and side property lines for new detached ADUs.
  • ADUs must comply with San Mateo County's fire safety standards, which may require sprinkler systems in certain cases.
  • Owner-occupancy requirements were suspended under California state law, allowing more flexibility for investors and homeowners alike.
