Landscape of ADU Real Estate In San Diego County

San Diego County boasts a diverse real estate market, and the rising trend of accessory dwelling units (ADUs) is transforming the way homeowners view their properties. With the growing need for additional living space, ADUs present a unique opportunity to optimize real estate investments.

ADU Real Estate: A Brief Overview

An accessory dwelling unit, commonly known as an ADU, is a secondary housing unit on a single-family residential lot. This additional living space can take various forms, including converted garages, standalone cottages, or attached additions. In San Diego County, ADUs have gained popularity for their versatility and potential to address the region’s housing challenges.

Recent California ADU Legislative Changes

In January 2023, California enacted AB 2221, AB 916, and SB 897 which contained over a dozen impactful ADU law changes. 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 laws 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.
