SB9 in Cupertino

Cupertino earns a C grade for SB9 implementation. This indicates the city has begun to allow some SB9 projects but remains restrictive and slow in approvals. Investors should recognize Cupertino as a market with emerging SB9 activity but still significant barriers. The limited number of approvals and restrictive local rules mean SB9 development is possible but not yet robust or predictable.

Cupertino’s SB9 ordinance is restrictive compared to many other cities. It imposes stringent design standards, setback requirements, and parking rules that limit the ease of subdividing lots or building duplexes. The ordinance includes minimum lot size thresholds and architectural controls that effectively raise the cost and complexity of SB9 projects. These restrictions reflect Cupertino’s status as an affluent Silicon Valley suburb focused on preserving neighborhood character. The ordinance is not standard or streamlined.

From 2022 through 2023, Cupertino saw no SB9 applications or approvals. This reflects both the city’s initial reluctance to implement SB9 and the deterrent effect of its restrictive ordinance. In 2024, applications increased to eight, but none were approved. This suggests that while interest in SB9 development grew, the city’s standards and review process prevented approvals. By 2025, the city approved two out of two applications, marking a shift toward some acceptance of SB9 projects. This change may reflect incremental adjustments in city staff approach or developer persistence rather than any major ordinance overhaul. Cupertino is not a charter city and has no related litigation affecting SB9 activity.

There is no record of any enforcement action by the California Department of Housing and Community Development (HCD) against Cupertino regarding SB9 compliance. The city has maintained its restrictive standards without triggering formal enforcement.

Investors should take a cautious, wait-and-see approach in Cupertino. The city is beginning to approve SB9 projects but remains a difficult market due to its restrictive ordinance and slow approval process. The low overall approval rate and limited volume suggest that SB9 development will require patience, careful project design, and possibly legal navigation of local standards. Cupertino’s affluent market and strong zoning controls mean SB9 is not a quick path to scale but could offer opportunities for well-prepared developers who can absorb the regulatory hurdles.
