Initial analysis

534-536 Oak Street is a three-story, four-unit multi-family residential building located in Hayes Valley, built in 1895 and currently owned by Loretta Mak. The building has undergone several significant maintenance and repair projects over the past two decades, including three major roofing projects, with the most recent completed in May 2024 at a cost of $12,200, following an earlier $3,000 roofing project in 2012. Window replacements were performed in 2001, involving the installation of 14 new windows at a cost of $6,780. The building has experienced recurring electrical issues, with recent repairs to the service conduit completed in September 2024, following similar electrical service repairs in 2012, and a concerning history of exposed wiring problems noted in complaints from 2018 and 2024.

Several building complaints have been filed over the years, with the most pressing being a loud alarm incident reported in September 2024 that required responses from police and PG&E. Previous concerns include a hazardous water heater installation in 2018, fire safety issues in 2002, and a leaking roof complaint in 1996. The property has shown a pattern of tree-related maintenance needs in the surrounding area, with multiple reports between 2016 and 2020 regarding damaged or dead trees requiring removal. More recent 311 calls from 2024 indicate typical urban issues such as garbage debris and noise complaints. While some historical complaints such as permit violations and fire egress concerns have been resolved, the building's maintenance record shows ongoing attention to basic infrastructure elements like roofing and electrical systems, with particular attention needed to address recurring electrical safety concerns.

Risk rating

How 534-536 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.
