Rent & eviction protection

Is 943 Columbus Ave 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.

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.

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, four-unit multi-family residential building at 943 Columbus Ave in Russian Hill, constructed in 1927, has undergone several significant renovations and maintenance projects over the past two decades. Most notably, there was a substantial restaurant remodel in 2013 costing $75,000, during which a UL300 fire system was installed and comprehensive electrical work was completed, including rewiring of the entire unit and first floor. The building has received regular maintenance including reroofing in 2014, installation of vinyl siding with foam insulation in 2006, and various unit-specific improvements. A concerning incident occurred in April 2020 involving unauthorized water shutoff that affected the entire building, though this complaint is now listed as not active.

The building experienced a series of fire safety violations in late 2005, including issues with fire escape ladders, fire extinguishers, and smoke detector requirements, though these were all abated by December 2005. More recent fire complaints in late 2016 regarding blocked exits and exit maintenance were also corrected. The property has maintained a good safety record since then, with two cooking-related fire incidents recorded but with no civilian injuries reported in either case. Recent maintenance records show regular upkeep, including street space permits in 2013 and 2015, though there have been recurring issues with sidewalk blockage due to scooters, with multiple reports from 2024.

Risk rating

How 943 Columbus Ave'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.
