Rent & eviction protection

Is 901-911 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 before 1979
Built 1909
2 or more units

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.

15+ years since occupancy
Built 1909
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-story, six-unit multi-family residential building at 901-911 Vallejo Street in Russian Hill, constructed in 1909, has undergone several significant infrastructure improvements over the past decade. Most notably, the building completed a mandatory soft-story retrofit in 2019 at a cost of $48,000 to comply with San Francisco's seismic safety requirements, and received its Certificate of Final Completion (CFC) to confirm the work was satisfactorily completed. The building has also seen substantial upgrades to its plumbing system, including recent work in January 2024, house trap and sewer replacement, which followed previous plumbing issues in 2011 when there was a violation for a defective house trap that was promptly resolved. Other maintenance work includes reroofing projects completed in 2014 and 1988, a bathroom remodeling project in 2012 that included both plumbing and electrical upgrades, and various routine inspections over the years.

The property has experienced multiple compliance issues related to the soft-story retrofit requirements, with violations reported in 2017, 2019, 2022, and most recently in 2023, though these have been resolved with the completion of the retrofit and issuance of the CFC. Historical building complaints from 2009-2011 included concerns about interior maintenance issues such as peeling paint, window functionality, and plumbing problems. The building's recent history shows consistent attention to maintaining essential systems, with records indicating prompt response to violations and completion of necessary upgrades. The property has also generated multiple 311 calls in 2024 regarding street cleaning issues, though these appear to be related to sidewalk conditions rather than building maintenance concerns.

Risk rating

How 901-911 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
6thpercentile

Out of 1133 buildings in this neighborhood, 1065 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
