Inner Mission, SF 94110 4265008 6 units · 2 fl · 1914

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 2840 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 1914

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 1914
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 6-unit, 2-story apartment building at 2840 25th Street in the Inner Mission, managed by the Helen Kong Trust, has undergone several significant improvements since its construction in 1914. Most notably, a mandatory soft-story retrofit was successfully completed in 2017 at a cost of $70,000, bringing the building into compliance with seismic safety requirements under SFBC Chapter 4D. The building received substantial electrical system upgrades in 2003 with the installation of 7-60 amp electric meters, indicating modernization of the power distribution system. More recent infrastructure improvements include various street space permits in 2020, 2018, and 2010, though their specific impacts on the building are minimal.

The property experienced several maintenance issues in late 2024, with eight separate reports of garbage and debris problems between November and December, including incidents of overflowing city garbage cans and other waste. These sanitation challenges appeared to be primarily street-related rather than directly linked to the building's interior conditions. The building’s maintenance history includes various historical permits such as a reroofing project from 1997 (which expired) and a door replacement project from 1984 (which was cancelled). A water service request was logged and resolved in November 2024, requiring basic troubleshooting of fixtures. The property appears to be generally well-maintained from a structural standpoint, with the most pressing recent issues being related to street cleanliness rather than building infrastructure or safety systems.

Risk rating

How 2840 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
39thpercentile

Out of 2380 buildings in this neighborhood, 1452 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
