Initial analysis

The property at 531-535 Irving Street is a 2-story, 4-unit multi-family residential building with ground floor retail, constructed in 1922 in the Inner Sunset neighborhood, currently owned by Tse Yat Ping & Chui Lan Cho. The building has undergone several significant maintenance and safety upgrades in recent years, including a new roof installed in January 2024 ($13,000), a completed sewer lateral replacement in January 2024, and compliance work with the ABE program in 2023. Historical improvements include the installation of hydronic wall heaters in 2013 and a fire suppression system in 2000. The property experienced notable heating issues in 2012 and 2021, with complaints about inadequate heating systems, leading to the installation of hydronic wall heaters and circulation equipment in 2012-2013.

The building's maintenance history shows periodic attention to safety systems, with fire alarm, extinguisher, and sprinkler system concerns noted in 2020 being corrected. Several violations were documented in 2003 and 2012, including security issues and fire safety compliance matters, though all were subsequently abated. Recent years have seen multiple noise complaints and some issues with garbage/debris reported through 311 calls, particularly in 2024, with a couple of noise-related cases still open. There were also periodic sidewalk repair permits issued in 2003, suggesting ongoing attention to exterior maintenance. The presence of the ground floor restaurant has generated some concerns, particularly regarding ventilation and exhaust, as noted in a 2012 complaint.

Risk rating

How 531-535 Irving 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.
