801 25Th Ave

Central Richmond, SF 94121 1668001 18 units · 3 fl · 1927

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 801 25Th 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.

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 1927
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 18-unit, three-story apartment building at 801 25th Avenue in the Central Richmond neighborhood was constructed in 1927 and is currently owned by the S&P Ng Family Trust 2007. The property has undergone several significant safety and maintenance improvements in recent years, most notably the recent fire alarm system upgrade completed in January 2024 to meet current code requirements for sleeping areas, with associated electrical and building permits totaling approximately $44,000. The building has successfully completed mandatory soft-story retrofitting as a Tier 2 property, with work valued at $90,000 completed in 2018, addressing earthquake safety concerns.

The building's maintenance history shows attention to various structural and safety issues, including window replacements to comply with building requirements (2020), and past fire safety concerns that have been addressed as needed. There were multiple building violations documented in 2002-2004 related to fire safety, lead paint, and general maintenance issues, all of which have since been closed or resolved. Recent fire safety inspections in 2017, 2020, and 2023 have resulted in violations that were corrected promptly, indicating ongoing attention to safety requirements. While there have been periodic complaints about common area conditions and maintenance issues over the years, particularly regarding hallways and laundry facilities in the late 1990s and early 2000s, current building records suggest improved maintenance practices. The property has received numerous parking-related complaints since 2022, though these are external to the building itself and primarily involve street parking violations.

Risk rating

How 801 25Th 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
2ndpercentile

Out of 2250 buildings in this neighborhood, 2205 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
