Understanding SB-1211 and What It Means for Your ADU Project

Accessory Dwelling Units (ADUs) have become a hot topic in home improvement and real estate. With the passing of Senate Bill 1211 (SB-1211 Land use: accessory dwelling units: ministerial approval) in California, converting existing structures like garages into ADUs has become easier and more appealing. Whether you’re looking to create additional income, increase your property value, or provide living space for family members, an ADU conversion could be the perfect project for you. Here’s everything you need to know, from understanding the new legislation to financing your ADU conversion.

Senate Bill 1211, recently passed in California, brings significant changes for homeowners interested in converting their garages or other structures into ADUs.

  • Ministerial Approval: Local agencies are required to approve ADU permits without discretionary review, streamlining the process.
  • Parking Requirements: The bill prohibits local agencies from requiring the replacement of offstreet parking spaces when converting a carport, covered parking structure, or uncovered parking space into an ADU.
  • Flexibility in Multifamily Dwellings: The bill allows for the creation of multiple ADUs within existing multifamily structures and up to eight detached ADUs on lots with multifamily dwellings.

These changes mean less red tape and more opportunities for homeowners to enhance their properties with ADUs.

Key Points from SB-1211 for ADU Projects

  1. Approval and Permits:
    • Ministerial Approval: Local agencies must approve ADU permits without discretionary review, ensuring a faster and more streamlined process.
    • Timelines: Permit applications must be considered and approved within specified timelines, typically 60 days.
  2. Parking Requirements:
    • Offstreet Parking: Local agencies cannot require the replacement of offstreet parking spaces when converting a carport, covered parking structure, or uncovered parking space into an ADU.
  3. Multifamily Dwelling Flexibility:
    • ADU Allowance: A local agency must allow at least one ADU within an existing multifamily dwelling and can permit up to 25% of the existing multifamily dwelling units as ADUs.
    • Detached ADUs: The bill increases the allowable detached ADUs on a lot with an existing or proposed multifamily dwelling from no more than two detached ADUs to up to 25% of the existing multifamily dwelling units.
  4. Development Standards:
    • Objective Standards: Local agencies can impose objective standards on ADUs, including parking, height, setback, landscape, architectural review, and maximum size of a unit, but these must not include requirements on minimum lot size.
    • Floor Area Limitation:
      • (A) A total floor area limitation of not more than 800 square feet for a detached ADU.
      • An ADU within an existing primary dwelling must not exceed 50% of the existing primary dwelling’s total floor area.
      • A detached ADU must not exceed 1,200 square feet.
  5. Setback Requirements:
    • No Required Passageway: No passageway shall be required in conjunction with the construction of an ADU.
    • Setbacks: A setback of no more than four feet from the side and rear lot lines is required for an ADU that is not converted from an existing structure or a new structure constructed in the same location and dimensions as an existing structure.
  6. Fire Safety:
    • Fire Sprinklers: ADUs shall not be required to provide fire sprinklers if they are not required for the primary residence. The construction of an ADU does not trigger a requirement for fire sprinklers in the existing primary dwelling.
  7. Zoning and Use:
    • Rental Terms: Rentals of ADUs must be for a term longer than 30 days.
    • No Density Increase: ADUs are considered accessory uses or buildings and do not exceed the allowable density for the lot upon which they are located.
  8. Utility Connections and Fees:
    • Impact Fees: Local agencies cannot impose impact fees for ADUs less than 750 square feet. For larger ADUs, fees must be proportional to the square footage of the primary dwelling.
    • Utility Connections: For ADUs described in specific sections, new or separate utility connections and related fees or capacity charges cannot be imposed unless the ADU was constructed with a new single-family dwelling.

These key points from SB-1211 significantly ease the process and regulations around the creation of ADUs, making it a more attractive and feasible option for homeowners.
