Commission approves ADU code amendments to align local rules with state law

The Pleasanton Planning Commission on Aug. 27 approved consent calendar items that included amendments to the municipal code intended to align local accessory dwelling unit (ADU) regulations with state law and guidance from the California Department of Housing and Community Development (HCD). The item was bundled on the consent calendar and was enacted by a single motion; the consent calendar passed by roll call vote, with commissioners voting unanimously.

Why it matters: State ADU statutes and HCD guidance have changed allowable standards and clarified where local regulations may be preempted or must be updated. Pleasanton’s amendments reorganized code language, added definitions to increase clarity, and updated development standards to conform with the state’s recent ADU rules.

Key clarifications reported at the meeting: Planner Emily Carroll told commissioners the local front yard (front setback) requirement for ADUs continues to apply consistent with the underlying zoning district, except where a statewide‑exempt ADU is precluded; side and rear setback standards (including longstanding 4‑foot side/rear allowances for certain ADUs) remain, and the amendments reorganize and re‑place language to improve readability. Staff said the redlined text in Exhibit A reflected a reorganization: where some specific setback language was removed in one section it was retained in a reworked development standards section. Staff also stated the edits were intended to reflect current state law and HCD guidance. Commissioners asked clarifying technical questions focused on front setback application, whether junior ADUs and detached ADUs remain permitted on the same lot (staff confirmed both remain allowed), and whether the amendments affected non‑exempt ADUs.

Actions and outcome: The consent calendar, which included the ADU municipal code amendments among five items, was approved by motion and roll call vote. The City Clerk recorded a unanimous vote: Commissioners Jane, Mohan, Pace, Wedge and Chair Morgan voted yes; Commissioner Jayco was absent. The staff‑recommended amendments move forward per the consent calendar action.

What’s next: Because the code changes were adopted on the consent calendar as a housekeeping and state‑consistency update, staff will implement the reorganized language in the municipal code and apply the clarified standards for future ADU permit reviews. Commissioners did not request the item be removed from consent for a separate hearing.
