Rent & eviction protection

Is 926-930 Vallejo St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1911

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Built 1911
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The three-unit residential building at 926-930 Vallejo Street in Russian Hill, owned by the Tom Chau Hung Wong Revocable Trust, has a documented history of structural maintenance and compliance issues spanning several decades. Built in 1911, this three-story flats and duplex structure has undergone multiple repair projects, most notably addressing recurring dry rot issues with rear stairs in 2015-2016, completed through several permits totaling $9,000, and the installation of a significant $45,000 reinforced concrete landscaping "sister wall" in 2015. The building experienced serious concerns between 2014-2019 regarding hillside subsidence, leading to violation proceedings and requiring both structural and safety inspections, though these issues were ultimately resolved through compliance as of April 2019.

More recent activity includes several permit revisions and inspections in 2023, particularly focusing on previously completed work from 2016, indicating ongoing attention to building maintenance and compliance. The property has maintained an active response to various municipal service calls in 2022-2024, addressing issues such as sidewalk defects, parking violations, and maintenance concerns. A documented cooking fire incident with no civilian injuries occurred at some point, though the date is unspecified. The building's history shows a pattern of proactive maintenance and compliance, particularly in addressing structural issues, while also revealing periods of significant required inspections and violations that have since been resolved.

Risk rating

How 926-930 Vallejo St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
