Initial analysis

The property at 61-63 Walter U Lum Place is a three-story mixed-use building constructed in 1906, containing 5 residential units above ground-floor retail space. The building has experienced significant maintenance and safety issues in recent years, most notably regarding fire safety systems. In October 2024, violations were issued for fire escape maintenance and extinguisher service requirements, and there is currently an active fire escape violation from January 2025. A notable cluster of violations occurred in late 2021 involving multiple fire safety systems, including blocked exits, sprinkler systems, alarm systems, and extinguishers, though these were subsequently abated.

The building has faced several challenges with its commercial space, including a period of vacancy that triggered compliance issues with the vacant commercial storefront ordinance in 2019, and current violations regarding unauthorized roll-down security gates installed in 2023. These gates were reported as unauthorized in January 2023, and the property is subject to monthly monitoring fees as a result. Historical records show various maintenance work has been performed over the years, including significant repairs in 1994 following fire damage (costing $50,000), and multiple sidewalk-related permits in the early 2000s. More recent plumbing issues were reported in 2022 regarding possible sewage water seeping into the basement, and the property has been the subject of numerous 311 calls in early 2025 related to street cleaning and sidewalk maintenance, with several cases involving garbage and debris that were resolved.

Risk rating

How 61-63 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.
