Should your city allow larger accessory dwelling units to help address local housing shortages?
The Santa Clarita Planning Commission has unanimously approved proposed amendments to local accessory dwelling unit (ADU) policies, creating a new Class 2 category for larger units. These changes, which still require final City Council approval, aim to address shifting housing regulations and expand options for homeowners.
Why it matters
The proposed amendments could change how homeowners in Santa Clarita plan property expansions by introducing larger unit size limits and clarifying parking rules. These adjustments reflect the city's effort to reconcile local housing codes with evolving state requirements for accessory structures.
The amendments introduce Class 2 ADUs with a maximum size of 1,000 square feet, while Class 1 junior units remain capped at 500 square feet and detached Class 1 units at 800 square feet. Additionally, parking requirements may be waived for properties located within a half-mile of a public transit center.
The players
Santa Clarita Planning Commission
The local regulatory body responsible for reviewing city land use, zoning amendments, and housing development policies.
Santa Clarita City Council
The local governing body that holds final authority over municipal code changes and housing policy implementation.
The details
The policy update creates a two-tier system to offer homeowners with existing primary residences more flexibility in building additional units. By adjusting building height and size rules, the city aims to standardize development opportunities regardless of whether the home is new or existing. The amendment also formalizes conditions for waiving parking mandates near transit hubs to simplify project planning.
Timeline
2021: Santa Clarita processed 61 ADU applications.
2024: Applications peaked at 95, up from 86 in 2025.
April 2026: City Council previously updated Class 1 ADU rules.
October 2026: Planning Commission approved the new policy draft.
The Home Front
This policy shift mirrors a growing trend across California as municipalities move to streamline accessory dwelling unit regulations. It directly follows the precedent set by state laws designed to increase density through secondary housing options on residential lots.
Homeowners should monitor the upcoming City Council meeting agenda to see when these policy changes reach a final vote. Before beginning any project, contact a licensed contractor or architect to verify if your specific property qualifies for transit-proximity parking exemptions.
The takeaway
These proposed changes aim to simplify the process of adding secondary units to residential lots in Santa Clarita. If you are considering a project, document your property's distance to the nearest transit center to determine if you may eventually qualify for parking waivers.
