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

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.
