Initial analysis

The three-unit multi-family residential building at 686-690 Hayes St in Hayes Valley was constructed in 1885 and is currently owned by Mjj Hayes LLC. The property has undergone several significant renovations in recent years, with three kitchen remodels completed between 2018 and 2021, including comprehensive electrical upgrades, window replacements, and various improvements to unit interiors. The building experienced water damage in 1990, requiring repairs to plaster and drywall, and underwent reroofing work in the same period. Historical violations were recorded in 2002-2009, including issues with fire extinguishers, handrails, and lead paint concerns, though all these violations were officially abated.

More recently, the building's exterior and immediate surroundings have faced some challenges, as evidenced by multiple municipal service calls in late 2024 and early 2025 regarding garbage, debris, and cleanliness issues, including reports of human waste. However, three routine safety inspections were conducted (2002, 2012, and 2019) without any noted ongoing concerns. The only recorded fire incident was a medical service call with no civilian injuries. While the property has maintained compliance with safety inspections and resolved previous violations, the recent pattern of external cleanliness issues suggests ongoing challenges with the immediate urban environment around the building.

Risk rating

How 686-690 Hayes 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.
