Initial analysis

The 11-unit, 3-story multi-family residential building at 524 Anza Street in the Lone Mountain neighborhood, owned by Patricia Louise Louie Seid, has a construction history dating back to 1963 and has undergone several significant maintenance and safety-related events over the years. Most recently, in 2023, there was a fire alarm system issue that was promptly corrected within 12 days. The building has faced multiple safety concerns and violations, particularly notable between 2006-2011, including problems with fire safety equipment, stairway safety (handrails and guardrails), and various interior maintenance issues such as damaged walls, ceilings, floors, and the presence of mold/mildew. These violations were ultimately resolved by October 2011. Historical maintenance records show window upgrades (2000), roofing work (1995), and other improvements dating back to 1984 when a solar hot water system was installed.

The property has undergone regular safety inspections over the years, with the most recent routine inspection recorded in 2017. Recent 311 calls from 2022-2024 primarily relate to street cleaning and sidewalk maintenance issues, including reports of garbage, debris, and waste management concerns, though these exterior issues appear to be promptly addressed by city services. There is also an unresolved noise complaint from August 2024. The building's documented history shows a pattern of addressing safety concerns and maintaining basic infrastructure, with particular attention to fire safety systems and habitability standards, though there were notable periods of multiple simultaneous violations requiring correction.

Risk rating

How 524 Anza 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.

Neighborhood percentile
