AI summary

The 10-unit, 3-story multi-family residential building at 742-744 Oak Street in Hayes Valley, owned by H/s Trust VI, was constructed in 1925 and has undergone significant improvements in recent years, particularly focusing on safety and modernization. The building completed a mandatory Tier 3 soft-story seismic retrofit program in 2015-2016, including installation of sprinkler systems in 2017 (with 19 new sprinkler heads and a monitoring system), demonstrating compliance with San Francisco's earthquake safety requirements. Major unit improvements were performed in 2021, including kitchen and bathroom remodels in Units 3 and 9, with associated plumbing and electrical work totaling over $64,000.

The building has experienced several maintenance and safety issues over its history, with the most concerning complaints arising in late 2021 regarding structural problems in Unit 4 (including a slanted floor, ceiling cracks, and window frame issues) and unauthorized renovation work. Historical records from the late 1990s show various maintenance concerns including plumbing issues, inadequate heating, and window problems, though many of these have been addressed through subsequent renovations. The property has maintained active compliance with fire safety regulations, with no active fire violations and recent inspections showing corrected conditions for combustible materials and other citations. A series of parking-related complaints regarding blockage of the driveway has been documented in late 2024, with multiple citations issued, though this is not directly related to building conditions or safety.

Risk rating

How 742-744 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.
