Initial analysis

The two-unit residential building at 526-528 Sanchez Street, owned by James R. Kistler, is a two-story flats and duplex structure built in 1910, located in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant infrastructure improvements over the years, including a roofing project costing $6,980 in 2002, window upgrades in 1992, and crucial plumbing work in October 2019 involving the replacement of the curb trap and sewer main. The building has experienced some maintenance challenges, most notably a plumbing leak incident in April 2012 that affected both the building and street, though this issue was resolved within days.

Recent maintenance history shows a pattern of water-related issues, with a sewage backup incident recorded in October 2019 and two water-related service requests in 2024. The building underwent unauthorized modifications in the past, leading to a variance application to legalize construction of open rear stairs, landings, and decks, though this request was disapproved. Although there have been various service calls and complaints related to the property's infrastructure, including building inspections and sewer issues, many of these cases have been resolved promptly through appropriate channels. The most recent building-related interactions with city services have primarily involved utilities and general maintenance matters, with no major structural or safety concerns documented in recent years.

Risk rating

How 526-528 Sanchez 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.
