Initial analysis

The 2401 24th Avenue building, located in the Parkside neighborhood, is a two-story, four-unit multi-family residential structure built in 1923 and currently owned by the Frank & Monica Duffy Trust. The property has undergone several significant maintenance and improvement projects over the years, with the most recent major work including the installation of new furnaces in 2019 and repairs to damage caused by a vehicle collision in 2018 that affected approximately 100 square feet of the ground floor. The building has a documented history of addressing safety and maintenance issues, including the replacement of 20 windows in 2001, wall repairs in 2018, and various exterior improvements such as vinyl siding installation in 2002.

Regular housing inspections have been conducted approximately every 5-6 years, with the most recent routine inspection occurring in 2023. The building has experienced several fire safety-related incidents, including violations in 2015 regarding fire extinguisher maintenance and egress obstruction, though these issues were subsequently resolved. A 2020 fire complaint about operating without a permit was also corrected. Recent concerns have been raised about building maintenance, with a 2023 complaint noting issues with peeling paint and roof structure. The property has undergone various plumbing and building improvements, including reroofing in 2004 and wall repairs in 2019. Recent 311 calls (2024) have primarily concerned external issues such as graffiti, parking violations, and street cleaning matters rather than building-specific concerns. The building's permit history demonstrates ongoing maintenance and compliance with safety requirements, though periodic violations and complaints indicate some recurring challenges with building upkeep and safety systems.

Risk rating

How 2401 24Th Ave'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 255 buildings in this neighborhood, 222 are predicted to be safer.
