Initial analysis

The three-unit, three-story multi-family residential building at 487-489 35th Avenue in San Francisco's Outer Richmond neighborhood was constructed in 1925 and is currently owned by Werner & Margarethe Ott 90. The building has undergone several substantial maintenance projects over the years, including a roof replacement in 1989 and the installation of vinyl siding on the rear wall in 1992. More recently, in December 2007, a gas line was installed for a dryer. The property has experienced recurring issues with moisture and mold, with multiple violations documented between 2007 and 2015, including complaints about mold on walls, water damage, and interior surface problems. Notably, a 2007 inspection revealed multiple interior issues including mold/mildew, floor covering problems, bathroom fixture concerns, and the presence of lead paint hazards, all of which were subsequently abated by November 2007. More recent complaints include low water pressure in the shower (2019) and a reported mold issue (2015), both of which were marked as not active. The building's maintenance history includes a significant tenant buyout transaction of $80,000 in November 2015 for one tenant at 489 35th Avenue. While there have been several routine inspections and violations, most have been addressed and abated, with the last documented active complaint related to water pressure issues from 2019. The property has had no reported abandoned vehicle issues in recent years, with all such complaints from 2015 being resolved promptly.

Risk rating

How 487-489 35Th 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.
