Initial analysis

The three-unit multi-family residential building at 971-975 Dolores Street in Noe Valley, owned by Zanco Trust The, has a complex history dating back to its 1912 construction. Most recently, the property underwent reroofing in 2017 at a cost of $17,800, and received underground electrical service improvements in 2004. A significant cluster of building violations was documented in early 2017, including issues with stairs, fire safety, security features, and more, though these were all abated by March 2017. The building experienced recurring maintenance challenges in the late 1990s, with tenant complaints in 1999 noting water leaks, window problems, and interior deterioration. A 2002 routine apartment inspection revealed multiple violations requiring correction, including issues with vent stacks, fireproofing, handrails, and lead paint concerns, which were addressed by 2004. More recently, in July 2017, there was a complaint about mold in one of the units. The property has been subject to regular routine inspections by Housing Inspection Services, with the most recent being in March 2017, covering all three units. The surrounding area has experienced typical urban maintenance issues, as evidenced by multiple 311 calls in recent years regarding street cleaning and debris removal, with the most recent instances occurring in late 2024, though these are not directly related to building conditions.

Risk rating

How 971-975 Dolores 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 1879 buildings in this neighborhood, 921 are predicted to be safer.
