Initial analysis

The property at 400 25th Avenue in the Central Richmond neighborhood is a two-story, 8-unit multi-family residential building constructed in 1961, currently owned by the Bing K Chan Decedents Trust. The building has undergone several significant improvements over the years, most notably completing a mandatory seismic retrofit of its soft-story structure in 2015 at a cost of $70,000, bringing it into compliance with San Francisco building codes. A gas utility inspection was conducted in 2007 for unit #7, which had reportedly not used gas for twenty years, and the building has received various maintenance updates including street space work (2018), meter installations (2015), kitchen cabinet remodeling (2001), and reroofing (1989).

The building experienced multiple serious issues in early 2002, with several building violations and complaints filed between January and April of that year, including problems with mold/mildew, water damage, damaged ceilings, fire escape maintenance, combustible storage, fire proofing materials, and egress obstructions. All these violations were officially abated by May 2002. More recent records indicate routine building maintenance and external upkeep, with several 311 calls in 2023-2024 primarily related to street cleaning and garbage debris on the property perimeter. Fire incident records show three minor incidents: a false alarm, malfunctioning smoke detector, and a smoke scare, none resulting in civilian injuries. The building's soft story retrofit status is marked as completed with a Certificate of Final Completion issued, indicating compliance with seismic safety requirements.

Risk rating

How 400 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.

Neighborhood percentile
7th percentile

Out of 2250 buildings in this neighborhood, 2092 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 47.3%
Moderate concern 39.9%
Severe concern 12.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
