Initial analysis

The two-unit residential building at 900 Silliman Street in the Portola neighborhood, owned by Dang Lu Van, is a two-story flats and duplex structure built in 1908. The property has experienced several significant maintenance and safety issues over the years, with the most recent being a September 2023 violation regarding weather proofing on siding, which was abated by December 2023. The building has a history of water damage and mold concerns, with a notable incident in January 2009 involving water leaks on the first floor that required repairs of approximately 960 square feet of water-damaged ceiling and walls. The property underwent various structural modifications between 1997 and 2000, including a vertical addition, conversion of ground floor space for habitable use, and installation of a driveway for garage access.

The building's electrical system was upgraded in 2004 with the installation of new lighting, switches, receptacles, and a 120-amp service upgrade. Multiple building violations have been recorded over the years, including lead paint hazards, interior surface issues, and problems with smoke detectors, though most of these have been resolved. A 2015 fire complaint regarding combustible materials was corrected within five days. More recently, there have been several 311 calls in 2024 related to street cleaning, parking issues, and environmental concerns, with most being addressed by city services. While the building has maintained compliance with housing codes through various repairs and upgrades, the repeated issues with water damage, lead paint concerns, and exterior maintenance suggest ongoing maintenance challenges.

Risk rating

How 900 Silliman St'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

Out of 255 buildings in this neighborhood, 199 are predicted to be safer.
