Initial analysis

The two-unit residential building at 859-861 36th Avenue in San Francisco's Outer Richmond neighborhood, owned by Michael M. and Donna M. O'Regan, was constructed in 1925 as a two-story flats and duplex structure. The property has experienced several significant events over its history, most notably a series of permit-related issues in 2007 where unauthorized bathroom remodeling work was conducted, including tile work and water heater installation without proper permits. This led to multiple violations and complaints, though all were eventually resolved by August 2007 through proper permit procedures and inspections.

More recently, in 2019, the building underwent weather-proofing repairs following a complaint about peeling paint and potential lead hazards, with these violations being abated by November 2019. The property has also seen various maintenance and infrastructure work, including electrical improvements in 2007 when two lights, switches, and circuits were installed. Recent municipal service calls from 2021 through 2025 have primarily concerned sidewalk parking violations and general street cleaning issues, which were handled by relevant authorities though the building itself was not directly involved in these external matters. The building's historical records indicate past attempts to revert it from unauthorized three-unit status in 1984, which appears to have been successfully completed, returning it to its original two-unit configuration.

Risk rating

How 859-861 36Th 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.
