Initial analysis

The three-story, five-unit multi-family residential building at 1566 Guerrero Street in Noe Valley was built in 1923 and is currently owned by Juan C Kong and Donna Kempner. The building has undergone several roofing projects, with permits issued in 2005 and 1996 for reroofing work, though both permits are now expired. The property has faced multiple safety and maintenance issues over the years, with three routine inspections conducted in 2000, 2008, and 2017 revealing various violations that were subsequently abated. Notable violations from these inspections included fire safety concerns such as uncharged fire extinguishers and a central alarm system requiring repair, as well as structural and safety issues including egress obstruction, security concerns related to roof access, and gas utility shutoff tool requirements. A concerning complaint was filed in 1998 detailing multiple interior issues including ceiling problems, paint chipping, window leaks, and concerns about the gas furnace, electrical system, and plumbing.

More recent interactions with city services have primarily involved 311 calls regarding external matters, including reports of an abandoned vehicle (resolved in 2019), environmental health concerns (2018), a homeless wellbeing check (2018), street cleaning issues (2017), and hazardous materials on public property (2010). While these external incidents are not direct reflections of building conditions, they provide context about the property's location and surrounding environment. The building's documented history shows a pattern of addressing safety and maintenance issues through routine inspections and permits, though some permits and violations have since expired or been marked as not active.

Risk rating

How 1566 Guerrero 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.
