Initial analysis

The two-story multi-family residential building at 1517-1521 Beach Street in the Marina neighborhood, owned by Brian Matthew & Susan Keene, was constructed in 1936 and contains three units. The most significant recent work on the property occurred in 2021, involving substantial excavation of impacted backyard soil, removal and replacement of various ground floor finishes, non-load bearing walls, and concrete slabs, with a documented cost of $125,000. The building has a history of maintenance and compliance issues, with multiple fire code violations recorded between 2016 and 2024, primarily related to alarm systems and general fire safety requirements. Notable violations from 2002 included fire safety deficiencies such as the need for garage ventilation, combustible storage issues, and various gas utility safety concerns, though these were all abated by October 2002.

The property underwent several renovation and repair projects in 1996, including kitchen modifications, reroofing, and addressing dry rot damage on stairways. An illegal short-term rental operation was documented and subsequently abated in 2018. More recent activity around the building has shown concerns with street-level conditions, including multiple reports of garbage and debris, though these were typically resolved promptly. The building has experienced numerous false fire alarms and system malfunctions over the years, with the most recent fire alarm system complaint in October 2024, which was corrected by November 2024. The property's maintenance history suggests regular upkeep, though the frequency of fire alarm and system-related incidents indicates ongoing fire safety system challenges.

Risk rating

How 1517-1521 Beach 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

Out of 988 buildings in this neighborhood, 168 are predicted to be safer.
