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 for garage conversion ADU in San Diego County. 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 for garage conversion ADU in San Diego County. The county’s updated ADU regulations include specific height allowances for 2-story units based on their proximity to transit and application review deadlines.

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)
Studio or 1 Bedroom ADU 2 Bedrooms  or more  ADU
500 sq. ft. 1,200 sq. ft. 850 sq. ft. 1,000 sq. ft.

There are no explicit limits on the number of bedrooms in a detached ADU.

Building Permit Requirements

Yes, you need to obtain a building permit before any kind of ADU construction, as per ADU laws in San Diego County. This crucial process verifies your unit meets important health, safety, zoning, and building code regulations.

The County PDS department reviews all ADU permit applications. They ensure your project adheres to regulations around:

  • Maximum size
  • Height restrictions
  • Setback minimums (distance from property lines)
  • Utility requirements
  • Parking rules

PDS also enforces the state’s 60-day application review limit.

Necessary Amenities

  • Complete kitchen
  • Bathroom (toilet, sink, shower)
  • Sleeping area(s)
  • Separate exterior entrance

Potential Other Requirements

  • Fire sprinklers
  • Parking space(s)
  • New utility meters and connections

Attached ADUs typically have lower amenity thresholds since they can share walls and systems with the main dwelling.

Utility Service Requirements

You will likely need independent utility infrastructure for a detached ADU, including:

  • Separate water line with a meter
  • Independent electrical panel and meter
  • Dedicated gas line, if applicable
  • Individual sewer/septic access

For attached ADUs, you can sometimes share utility connections with the primary dwelling or sub-meter of the ADU usage.

Utility connection costs often reach $5,000+ for detached ADUs but may be far less for attached units. Verify requirements and costs upfront with local utility companies.

ADU Permit Cost Breakdown

As part of a temporary county fee waiver program through January 2024, ADU laws in San Diego waive certain ADU plan check costs. However, you must still pay building permit fees, impact fees, and potentially utility connection and capacity charges.

Typical ADU permit costs include:

Plan Check Fees

  • Review of construction plans
  • $800 – $2,500
  • Waived through January 2024

Building Permit Fees

  • Approval to begin construction
  • $2,500 – $5,000+
