Initial analysis

The two-unit residential building at 747-749 Oak Street in Hayes Valley, owned by Frank M. Conolly and Je Grooms, is a two-story flats and duplex structure built in 1900. The property has undergone several significant improvements over the past two decades, with the most recent major work being a $23,990 reroofing project issued in August 2021. Previous maintenance included a $7,000 repair of the front entry stairway in 2004, which involved fixing newel posts, adding balustrades, and painting, window replacements in 2003, and the installation of vinyl siding in 2002 on the back and right sides of the building.

The building's street and sidewalk area has experienced regular maintenance needs and occasional incidents requiring city services between 2022 and 2024. This includes multiple cases of garbage and debris cleanup, with the most recent incidents occurring in December 2024. Notably, there was one instance of medical waste reported (needsles) in September 2023, though nothing was found upon investigation. A brief period of flooding was reported in December 2022, but the initial response found no issues. Two medical assistance incidents were recorded in the vicinity, though neither resulted in civilian injuries. The building's maintenance record shows consistent attention to basic upkeep, with no major violations or safety concerns noted in the available data.

Risk rating

How 747-749 Oak 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
89th percentile

Out of 1027 buildings in this neighborhood, 113 are predicted to be safer.

12-Month severity forecast

Moderate concern 10.6%
Severe concern 10.1%
