Initial analysis

The property at 448 25th Avenue in the Central Richmond neighborhood is a two-story, three-unit multi-family residential building constructed in 1983, currently owned by the Wong/chui Revoc Trust. The most significant recent improvement to the building was completed in July 2023, involving a comprehensive $70,000 renovation of Unit #3 that included kitchen and bathroom upgrades, flooring replacement, and repainting. Historically, the building experienced a series of fire safety violations in 2003 related to smoke detectors and combustible storage, though all these issues were resolved by October 2003.

The building's maintenance record shows a mixture of routine issues typically faced by older properties, including several 311 calls between 2008 and 2024 regarding external concerns such as garbage, cleaning, and hazardous materials. Specific incidents included reports of hazardous liquids (2008), graffiti (2010), and various waste management issues in the surrounding area, with the most recent complaint in July 2024 regarding abandoned electronics. While these external matters have generally been addressed promptly, they represent typical urban property management challenges. The building's permit history shows proper maintenance and upgrading of units over time, with the most recent major improvements focusing on modernizing Unit #3's amenities and interiors.

Risk rating

How 448 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.
