Initial analysis

829 Hayes Street is a three-story, six-unit multi-family residential building constructed in 1900, currently owned by Joanne R. Minsky. The property has undergone significant maintenance and improvements in recent years, most notably completing its mandatory soft-story retrofit in 2022 at a cost of $90,000, which included installing a new fire alarm system throughout the building. The building has experienced persistent maintenance challenges, particularly in 2023, with multiple tenant complaints regarding water damage, leaks, structural issues, and mold. These issues appear to be linked to roof problems, with related repairs including reroofing work completed in February 2023 costing $27,500. The building has seen substantial recent activity in Unit 4, with multiple renovations including bathroom remodeling ($20,000) and kitchen updates in 2023, along with various maintenance repairs in response to a 2023 complaint.

Historical records show the building has a pattern of fire safety and structural maintenance issues, including multiple violations from 2008-2019 regarding fire safety systems, handrails, and other safety equipment, though these were eventually abated by 2022. Recent work has focused on addressing these legacy issues, including a partial water repipe installation in 2017 and various unit-specific electrical and plumbing upgrades. The property has also undergone several significant structural repairs, including replacement of rotted wood retaining walls and lagging boards in late 2022. A recent fire violation issued in April 2024 regarding the alarm system was noted, though this was subsequently abated. The building has maintained an active maintenance schedule, with numerous permits filed and completed for various repairs and improvements, indicating ongoing management engagement with building systems and tenant needs.

Risk rating

How 829 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.
