Initial analysis

The two-unit residential building at 753-755 Oak Street in Hayes Valley, constructed in 1890, has undergone several significant renovations and maintenance work over the past 15 years. The most substantial improvements occurred in 2010, including a $40,000 remodel and garage conversion project, foundation work, and electrical system upgrades to 200-amp service with additional lighting installations. The property has also addressed critical maintenance issues, with records showing treatment of excessive dry rot, termite infestation, and substandard construction on the east elevation wall. In 2011, bathroom improvements were completed, including fixtures replacement and installation of high-efficiency lighting. The building has experienced minimal safety incidents, with only one recorded fire incident involving a contained cooking fire with no civilian injuries.

Recent monitoring of the property through 311 calls shows consistent maintenance of public areas, primarily involving street cleaning and sidewalk maintenance, with most cases being resolved without requiring significant intervention. Parking enforcement has been needed on two occasions for blocked driveways, with citations issued in both instances. The frequency of general cleaning calls between 2021 and 2024 suggests ongoing attention to exterior maintenance, though most cases were resolved with minimal action required. The building's maintenance history indicates regular upkeep and infrastructure improvements, particularly during the 2010 renovation period, with no major structural or safety concerns reported in recent years.

Risk rating

How 753-755 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.
