SB9 in Santa Rosa

Santa Rosa earns a C grade for SB9 implementation. This indicates moderate activity and some level of compliance with SB9 requirements, but with clear signs of slowing momentum. Investors should approach with caution as the city shows limited approvals relative to applications and a declining trend in recent years.

Santa Rosa’s SB9 ordinance is a North Bay city program with generally standard provisions. It allows lot splits and duplex developments consistent with state SB9 law. The ordinance includes typical setback requirements, minimum lot sizes aligned with state thresholds, and standard design and parking rules. There are no unusual restrictions or incentives beyond the baseline SB9 framework. The city’s approach is straightforward but does not aggressively encourage SB9 projects.

Santa Rosa began with very limited SB9 activity in 2022, approving its only application that year. In 2023, applications increased sharply to 10, but approvals lagged at only 2. This suggests the city was either cautious in granting approvals or encountered barriers in processing or compliance. By 2024, applications dropped to 2 with no approvals, and in 2025 no applications were filed. The overall trajectory is sharply downward after a brief surge. This decline may reflect growing uncertainty or frustration among applicants due to local administrative hurdles or design standards. There is no record of charter city litigation affecting SB9 activity here. The city’s ordinance is in place and functional, but the low approval rate and falling application numbers indicate that Santa Rosa is not fully embracing SB9 as a tool for housing expansion.

There is no record of any HCD enforcement action against Santa Rosa related to SB9 compliance. The city appears to be meeting minimum state requirements without triggering formal enforcement.

Santa Rosa is a wait-and-see market for SB9 investors. The low approval rate (3 out of 13 applications) and declining application numbers suggest that local conditions are not currently favorable for reliable SB9 development. While the ordinance is in place and the city is not under enforcement pressure, the administrative environment or local policies may be limiting approvals. Investors should monitor for any policy shifts or improvements in approval rates before committing. At this time, Santa Rosa does not offer a strong or predictable SB9 opportunity.
