Rent & eviction protection

Is 3440 25Th 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 1932

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 six-story, 55-unit apartment building at 3440 25th Street in the Inner Mission, owned by Anthony & Diane Martorana R, has experienced several significant maintenance and safety-related issues in recent years. Most notably, there are currently three open fire violations as of November 2023 regarding sleeping area requirements, alarm system maintenance, and sprinkler system maintenance, along with multiple fire safety concerns between 2022-2023 including blocked exits, fire escape issues, and hazardous materials. The building has a concerning history of elevator problems, with a notable complaint in December 2020 about consistent disrepair impacting accessibility for elderly and disabled residents. The property has undergone various major systems upgrades, including a $65,062 project in early 2024 to install additional fire notification devices and low-frequency sounders in sleeping areas, a 2014 boiler replacement project, and significant electrical and interior renovations in 2003. The building has experienced multiple incidents requiring emergency response, primarily for elevator rescues, water evacuation, and occasional cooking fires, though fortunately no civilian injuries have been reported. Recent maintenance challenges are highlighted by multiple complaints in 2021-2024 regarding boiler permit renewals and recurring issues with debris and waste management outside the building, as evidenced by multiple 311 calls for garbage and sidewalk cleaning between 2024-2025.

Risk rating

How 3440 25Th 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
0thpercentile

Out of 2380 buildings in this neighborhood, 2380 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
