Initial analysis

The property at 2512 San Bruno Ave is a two-unit multi-family residential building with commercial space, constructed in 1915 and currently owned by Robert and Diana Chan. The two-story building's history reveals several significant events, most notably in 2007 when Housing Inspection Services documented multiple violations including an unpermitted rear ground-floor unit installation, heating system failures, mold and mildew issues, and sanitation concerns. These violations were eventually addressed through a permit (200706295560) requiring the removal of the unauthorized kitchen and cooking facilities, with all violations notably abated by September 11, 2007. Prior to this, the building had undergone various modifications including an electrical service upgrade in 2003 (200 amp with 2 meters) and attempts to relocate kitchen facilities in the 1990s, though some related permits expired.

More recent history shows ongoing maintenance challenges, with multiple 311 calls in early 2025 regarding garbage and debris on the property and surrounding area, along with reports of graffiti. A fire complaint was recorded in August 2022, which was referred to another agency. The building's planning records indicate a historical issue with unpermitted work and unsafe building conditions, though these matters have been closed as "Approved" and "Abated" respectively. While the property has experienced various compliance issues over the years, significant efforts were made in 2007 to address the most serious violations, and there have been no major building violations recorded since that time.

Risk rating

How 2512 San Bruno 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
52th percentile

Out of 255 buildings in this neighborhood, 122 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Property class: apartment building

Apartment building — this property classification influences expected violation rates.

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 74.7%
Moderate concern 19.5%
Severe concern 5.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
