Rent & eviction protection

Is 3234-3242 16Th 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.

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 1911
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 3234-3242 16th Street in Mission Dolores, owned by Martin M. Cheng and Annie W. Fa, has undergone several significant improvements and faced various challenges since its construction in 1911. Most notably, in July 2023, the building received a comprehensive fire alarm system upgrade valued at approximately $20,567, including new addressable smoke detectors, manual pull stations, and low-frequency horns in all residential sleeping areas, bringing the building into compliance with current fire safety standards. The property has experienced recurring maintenance issues, including a lead paint hazard concern in 2020 that resulted in multiple violations, which were ultimately abated by November 2021. Other notable improvements include a complete window replacement project in 2006, installation of new concrete in the parking lot in 2010, and various electrical upgrades in 2003, including a main service replacement.

The building has faced several challenges in recent years, including complaints about a vacant ground floor retail space in 2022 that was reportedly suffering from vandalism and neglect, though this issue was marked as resolved in December 2022. Multiple routine inspections have shown varying degrees of maintenance compliance, with several violations recorded in 2020-2021 related to paint problems, lead hazards, and building systems. The property has also experienced periodic infrastructure issues, including a sewage leak in 2020, though this was addressed by the landlord. Recent 311 calls from 2023-2025 have primarily concerned exterior maintenance issues such as garbage concerns, graffiti, and parking violations, though these are not necessarily indicative of building conditions. The building's fire incident record shows three minor incidents between 2020 and 2023, none resulting in civilian injuries or significant damage.

Risk rating

How 3234-3242 16Th 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
3rdpercentile

Out of 799 buildings in this neighborhood, 775 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
