Rent & eviction protection

Is 750-760 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.

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.

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, 8-unit building at 750-760 Columbus Avenue in North Beach, owned by Tomac Property Ventures LLC, has experienced several significant issues over the past seven years. Most notably, there are ongoing concerns regarding unauthorized modifications to the building, with an active Notice of Violation filed in September 2023 for façade alterations without proper permits, and a subsequent Final Warning Notice issued in December 2023 leading to a scheduled Director Hearing in February 2025. The property has a history of construction-related violations, including multiple complaints about work done without permits between 2021 and 2024, particularly concerning altered entryways and unauthorized installations like an awning and store entrance modifications.

The building's maintenance and safety record shows a mix of concerning and routine issues. A serious complaint was filed in July 2024 regarding the ground level/basement conditions, including clogged drains, uncovered sewage pipes, and hanging insulation with potentially asbestos material. There have been three fire incident responses between 2021 and 2025, though none resulted in civilian injuries or fatalities. The property has undergone some permitted work, including a $25,000 project in 2020 to install new antenna equipment and replace a faux chimney. Additionally, there have been multiple 311 service requests in recent years regarding various building-related issues, including reports of garbage/debris and discolored building surfaces, though many of these cases were resolved without significant findings. The building's inspection and violation history, combined with recent service requests, suggests ongoing challenges with maintenance and regulatory compliance, particularly regarding unauthorized modifications to the structure.

Risk rating

How 750-760 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.

Neighborhood percentile
10thpercentile

Out of 362 buildings in this neighborhood, 326 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
