The Homework: January 16, 2025

January 16, 2025

Welcome to the January 16, 2025 Main edition of The Homework, the official newsletter of California YIMBY — legislative updates, news clips, housing research and analysis, and the latest writings from the California YIMBY team.


News from Sacramento

The State Legislature is back in session, and the first round of housing bills are beginning to make the rounds. The final deadline for bill submission is February 21.

Thus far, California YIMBY has sponsored SB 9 with newly-elected Senator Jesse Arreguín as the author. This bill clarifies that previous legislation exempting Accessory Dwelling Units (ADUs) from owner-occupancy requirements applies to all ADUs, and not only units built after the law went into effect. The bill is intended to send clarification to cities that have interpreted existing law to only apply to new ADUs, and continue to impose owner-occupancy requirements on ADUs built before the state ban was passed.

Our Legislative team expects to roll out the balance of our legislative priorities by the end of January. Watch this space for more detailed news, and sign up for our e-mail list (or follow us on social media) to get real-time updates about our plans.

During the holiday season, the State Senate and Assembly announced their committee assignments for the rest of the year. Below is a list of Committee assignments for committees that are most likely to hear our sponsored and high-priority bills:

Senate Housing Committee:

  • Senator Aisha Wahab (Chair)
  • Senator Kelly Seyarto (Vice-Chair)
  • Senator Jesse Arreguín
  • Senator Christopher Cabaldon

Housing Research & Analysis

How-To ADU: The Handbook

Over the past eight years, California lawmakers have adopted dozens of reforms designed to make it easier for homeowners to build Accessory Dwelling Units (ADUs), which are sometimes referred to as “granny flats,” in-law units, or casitas.

To help homeowners, building professionals, and local planners understand these changes, which are often complex and technical, the California Department of Housing and Community Development (HCD) has published an ADU Handbook, which has been expanded and revised to include the most recent legislation.

Key Takeaways:

  • ADUs are now allowed within multifamily buildings, and up to 8 detached ADUs may be built on a lot with an existing multifamily structure.
  • Owner-occupancy requirements have been permanently banned.
  • HCD now has authority over ADU enforcement.

Enhancing Mobility for Older Adults: Insights from Land Use in the U.S. and Japan

As America’s population ages, the need to provide safe and efficient mobility from far-flung suburbs and subdivisions grows more acute. Our current transportation systems, land use, and development patterns all but mandate private car ownership and driving – which is both expensive for seniors on fixed incomes, and more concerningly, dangerous: Older drivers are disproportionately represented in deadly car crashes.

What are the options for older people who wish to “age in place” in their communities, but either can’t afford to drive, or can no longer do so safely? In A tale of two aging nations: How do urban designs impact older adults’ mobility in automobile versus transit societies?, Ashley Wan-Tzu Lo and Suman Kumar Mitra explore how urban design impacts the mobility of older adults in two contrasting environments: the automobile-oriented United States, and transit-oriented Tokyo, Japan.

Key Takeaways:

  • Older adults in Tokyo were more likely to take “active” trips (i.e., walk or bike) or ride transit, but less likely to drive.
  • Older adults living in larger, denser cities with more accessible transit are more likely to make trips out of the house, less likely to rely on cars, and more likely to engage in social activities outside the home.
  • Proximity to transit affects older adults’ likelihood of using transit: those who live closer to stations are more likely to use transit, less likely to drive, and tend to drive less than older adults who live further from transit stations.
