Rent & eviction protection

Is 947-951 Jones 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 1909

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 property at 947-951 Jones Street is a three-story multi-family residential building constructed in 1909, containing 4 units and currently owned by the Kin Chi Chow Family Grantor. The building has undergone several significant improvements over the past decade, including a complete roof replacement in 2024 costing $27,000, bathroom legalization work in 2013, comprehensive window replacements, and major HVAC system upgrades including furnace installation and ductwork. However, the building has also experienced numerous serious issues, particularly in 2012-2013, including violations for improper occupancy as a converted SRO with guest rooms, unauthorized construction work, and multiple habitability concerns such as inadequate heating, lack of smoke detectors, and non-operational fire sprinklers.

Between late 2012 and early 2013, the building faced multiple housing code violations that were subsequently abated, including illegal room rentals, unpermitted window replacements, and heating system deficiencies. There were also several complaints about unauthorized construction work and plumbing issues, including improper water heater installation and venting. The building's maintenance record shows regular updates and repairs, with the most recent significant work being the 2024 roof replacement. The property has been subject to routine housing inspections in 2000 and 2010, and while recent 311 calls from 2022 to 2024 mainly relate to sidewalk and street cleaning issues, there have been no recent building-related complaints or violations on record. The building's history suggests a pattern of unauthorized modifications and occupancy violations, though most of these issues appear to have been resolved through subsequent corrections and permits.

Risk rating

How 947-951 Jones 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
94thpercentile

Out of 448 buildings in this neighborhood, 27 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Neighborhood (ZIP code)
