Cupertino planning commission trims non-state code changes, approves SB‑9 alignment edits

The Cupertino Planning Commission unanimously recommended city council adoption of municipal code amendments that align single‑family development standards with recent state law but directed staff to remove non‑state-law changes for separate consideration.

The commission’s public hearing on the application (identified in the staff presentation as the citywide municipal code amendment package) focused on two categories: updates required to implement state bills described by staff as "SB 4 50" (presented as the state change affecting SB‑9 review timelines and standards) and a set of locally initiated clarifications and administrative policies. Emmy Sugiyama, project manager in planning, told the commission the changes would update definitions, move some zoning language into the landscape code, add objective lot and subdivision standards for two‑lot subdivisions, and incorporate standards previously applied only to SB‑9 projects into all single‑family development standards.

The code updates the city presented would, according to staff, remove the ability to impose certain limits previously applied to SB‑9 developments (for example, a 2,000‑square‑foot limit and special basement/balcony restrictions), and require the city to either approve or deny complete SB‑9 applications within 60 days as set by state law. Staff also proposed two administrative rules: an expiration for inactive applications after 180 days and a restriction on demolishing residential units before a replacement is proposed.

Commissioners raised concerns about locally added requirements and resident costs. Commissioner Scharf asked about the new requirement for peer review of arborist reports and whether that would double costs for homeowners; Sugiyama said applicants could use city‑retained consultants as an alternative but acknowledged costs vary by project. Multiple commissioners questioned the 180‑day automatic expiration for inactive applications, noting the potential for large projects to incur significant fees and asking for clearer protections for homeowners and for staff discretion. Commissioners also sought clarity on which code changes were required by state law and which were local policy.

After discussion, Chair Rao moved — and the commission seconded — to advance the amendments necessary to comply with state law and to carry forward only minor spelling/readability corrections, while removing and returning to a future agenda any newly introduced local administrative standards (such as the 180‑day expiration and the demolition restriction) for separate public consideration. The motion was adopted unanimously.

The commission’s action does not itself change the municipal code; it forwards the recommended, narrowed package to the city council with the commission’s direction that non‑state changes be split out and re‑noticed. Staff said they will present the state‑required updates and spelling/readability corrections to council and return proposed local policy additions as a separate item with cost estimates and more detailed justification.

Commissioners and members of the public also asked staff to provide clearer cost estimates for the arborist peer‑review option, and to show which edits are strictly required by state law in the materials council will receive.

The planning commission’s recommendation was recorded as a unanimous vote at the meeting.
