Initial analysis

The two-unit residential building at 691-693 39th Avenue in San Francisco's Outer Richmond district is a two-story flats and duplex structure built in 1944, currently owned by the Rosa Shieh Trust 2005. The property has undergone several significant improvements over its lifetime, with the most recent major work being a street space modification and water line replacement completed in March 2017. Prior to this, the building received a new roof in 2012 at a cost of $9,000, following two earlier roofing projects from 1991, indicating regular maintenance of this critical building component. In 1989, substantial interior renovations were performed, including two bathroom remodels (one successful, one expired), and a kitchen remodeling project that upgraded cabinets and countertops.

The building's external environment has experienced some maintenance challenges, as evidenced by three 311 calls in recent years regarding street and sidewalk conditions. Most recently, in July 2024, there were reports of illegal postings and debris on or near the property, both of which were resolved through city services. An earlier incident in January 2020 involved waste removal. While these exterior issues have been addressed promptly, they represent the most recent concerns associated with the property. The building's documented history shows regular maintenance and updating of essential systems, with no reported safety violations or major structural concerns in the available records.

Risk rating

How 691-693 39Th 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.
