Initial analysis

The property at 49-57 Walter U Lum Place is a 3-story, mixed-use building constructed in 1930, containing 4 multi-family residential units and ground-floor commercial space, currently owned by Sam Yick Benv Assn Western. The building has undergone several significant changes over the years, including the commercial space's conversion from a grocery store to a coffee shop in 2012, and more recently, issues regarding unpermitted signage and awnings that resulted in multiple Notices of Violation (NOV) in January 2023. To address these violations, the property owner has initiated compliance actions through the Awning Amnesty Program in May 2024, with multiple permits issued and completed for this purpose.

The building has a documented history of fire safety concerns, with multiple fire code violations recorded between 2014 and 2022, including issues with sprinkler systems, fire escapes, and alarm systems, though most were subsequently abated. Recent electrical work in 2022 involved the installation of outlets for an automatic door closer, suggesting security improvements. The property has maintained active compliance efforts, as evidenced by the recent permit activity, though two building violations from January 2023 regarding unpermitted signage and awnings remain listed as active. The surrounding area has experienced various municipal service calls in early 2025, primarily related to maintenance and environmental issues, though these are more reflective of the neighborhood rather than the building itself.

Risk rating

How 49-57 Walter U Lum Pl'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.
