Rent & eviction protection

Is 353-355 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 before 1979
Built 1910

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 1910
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 353-355 Columbus Avenue property is a three-story, 6-unit multi-family residential building constructed in 1910, currently owned by 353-355 Columbus Ave Sf LLC. The building has undergone several significant maintenance and safety upgrades over the years, including a roof replacement in 2007 ($16,500), the installation of a restaurant fire suppression system in 2005, and multiple plumbing improvements including a 2018 backflow preventer installation, 2016 water main replacement, and 2013 heating system upgrades. The property has faced periodic regulatory scrutiny, with several fire safety and operational violations recorded between 2021 and 2024, though most have been promptly addressed upon inspection. Recent fire safety issues included three complaints in 2024 regarding overcrowding and operating without a permit, and multiple alarm system violations between 2022 and 2024. Building inspections in 2005 and 2011 revealed various code compliance issues that were subsequently resolved, including lead paint concerns, fire egress obstructions, and security concerns.

The property has maintained active maintenance practices, as evidenced by numerous street space permits issued between 2013 and 2016, and regular updating of critical systems and equipment. Recent 311 calls from late 2024 indicate some ongoing neighborhood concerns in the vicinity, including illegal parking and environmental health matters, though these are external to the building itself. The building's historical permit and violation records show a pattern of routine maintenance and responsive actions to regulatory requirements, with most violations being resolved through proper channels. The property's planning records show the restaurant use (Mona Lisa, Inc.) has been permitted as a continued operation, suggesting successful compliance with business use regulations. The building's fire incident records show no serious incidents requiring emergency response, though there have been several false alarms and system activations typical of older buildings with legacy safety systems.

Risk rating

How 353-355 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

Grade A–B — Low risk

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

Grade C — Moderate risk

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

Grade D–F — High risk

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

Neighborhood percentile
54th percentile

Out of 684 buildings in this neighborhood, 315 are predicted to be safer.
