Initial analysis

The property at 3751 24th Street is a two-story, five-unit multi-family residential building with a ground-floor commercial space, originally constructed in 1900 and currently owned by Sharon M Cassidy. The building has experienced several notable events over the past few decades, with the most significant recent concerns centering around unauthorized construction activities. In April 2024, there was a report of unpermitted construction work, with construction materials being brought in and concerns about parking violations. Similar unpermitted construction issues were also reported in 2020, 2012, and 2011 regarding both residential and commercial spaces. The building underwent substantial electrical work in 2004, receiving a new 400-amp underground service and load centers for both residential and commercial sections.

The property has a history of maintenance and safety-related issues, particularly in 2007 when multiple violations were documented, including problems with exterior paint, egress obstruction, security requirements, and lead paint hazards - all of which were subsequently abated by July 2007. A 2009 complaint highlighted concerns about broken stairs, non-functioning lights, and window security issues. The commercial space has undergone various improvements over the years, including window replacements in 2012 and kitchen and bathroom renovations in 2006 (though these permits expired). The building's infrastructure has received attention over time, with a roofing project completed in 1994 and various electrical upgrades. Recent 311 calls from late 2023 to early 2024 primarily concern street-level maintenance issues, including garbage removal and parking enforcement, rather than building-specific problems. Two minor fire-related incidents were recorded in 2010 and 2017, both with no civilian injuries reported.

Risk rating

How 3751 24Th 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 1879 buildings in this neighborhood, 1691 are predicted to be safer.
