AI summary

The two-unit, two-story residential building at 529-531 Buchanan Street in Hayes Valley, owned by Tunde E. Munz-Abraham, was constructed in 1900 and is classified as a Flats & Duplex structure. The property has undergone several significant renovations and maintenance work over the years, most notably a $20,000 reroofing project that was permitted in August 2023. In 2010, a major renovation project was filed to add 2,000 square feet to the building, including new garage and deck construction, while addressing issues like dry rot repair on both south and north walls. The building's historical significance is notable, as it is listed on the California Historic Register as a D2-listed property, and in 2010 received approvals for a significant rear yard addition that would increase the structure's size to approximately 4,120 square feet.

Recent activity around the building has involved multiple street cleaning and parking enforcement issues in 2024, with several reports of garbage and debris on the street and instances of illegal parking, including sidewalk parking and driveway blocking. However, these external issues do not necessarily reflect on the building's internal condition. The only recorded safety-related incident was a carbon monoxide detector activation with no actual CO detected. The building's maintenance record shows regular upkeep, with particular attention paid to roof maintenance and structural integrity, as evidenced by the recently permitted reroofing project and previous dry rot repairs.

Risk rating

How 529-531 Buchanan 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.
