Recent California ADU Legislative Changes

In January 2023, California enacted AB 2221, AB 916, and SB 897 which contained over a dozen impactful changes for ADU laws in San Diego. Most notably:

  • Height Restriction Overrides: The new laws allow homeowners in certain areas to build 2-story detached ADUs subject to maximum height limits such as 18 or 25 feet, depending on location specifics. This enables the construction of ADUs with enough height for a second level.
  • Expedited Review: The state mandated a 60-day limit for local agencies to approve or deny ADU permit applications after submittal. This stringent deadline aims to accelerate project approvals.
  • Affordability Incentives: The ADU laws in San Diego County standardize an affordable housing density bonus that enables homeowners to build additional market-rate units if they designate some ADUs as income-restricted affordable housing.

San Diego County adopted guidelines to reflect these 2023 ADU laws. The county’s updated ADU regulations include specific height allowances for 2-story units based on their proximity to transit and application review deadlines.

Where Are ADUs Allowed in San Diego County?

You can only build an ADU on a residentially zoned property with an existing single-family home per county zoning regulations. Use this zoning lookup to verify your eligibility by entering your assessor’s parcel number (APN).

If your property qualifies, you may be able to have up to one detached ADU plus one junior ADU on the lot. A junior ADU (JADU) is a smaller dwelling (maximum 500 sq ft) created within the walls of the primary residence.

JADUs must include an efficient kitchen, separate entrance, and interior entry to the main home. The owner must reside on-site within either the JADU or primary dwelling.

ADU Laws in San Diego County: ADU Size Requirements

The maximum ADU sizes allowed depend on whether the unit is attached or detached:

Square Footage of Existing single-family residence (SFD) Maximum Allowed Square Footage for Detached ADU Maximum Allowed Square Footage for Attached ADU (up to 50% of SFD)
