Initial analysis

The two-unit residential building at 275 24th Avenue, located in the Lake-Presidio neighborhood, is a two-story flats and duplex structure built in 1923 and currently owned by the Fong Surviving Spouse Trust. The property has undergone several significant infrastructure improvements over the years, with the most recent being a completed 200-amp electrical service upgrade in July 2021. Earlier improvements include street space repairs in 2010, both street space and sidewalk work in 2005, window replacements in 2005 (replacing 9 bedroom windows and one bathroom window), and a completed house trap replacement in 2010. An attempt to perform reroofing work was initiated in 1997 but the permit expired without confirmation of completion.

The property has experienced multiple street-related issues in recent years, including two garbage and debris incidents in 2024 and 2022, which were resolved by Recology. A tree maintenance request in November 2021 was inspected by an arborist who determined it was not an urgent safety hazard. The building's immediate vicinity has faced recurring parking issues, with three documented incidents in October 2019 involving vehicles blocking driveways and one incident of sidewalk parking, though not all resulted in citations. The property underwent parking enforcement complaint forwarding in October 2013, and there was one general customer callback to Public Works in March 2017. The history suggests ongoing maintenance of essential systems, though recent garbage incidents and parking enforcement actions indicate some neighborhood challenges, particularly related to street cleanliness and parking compliance.

Risk rating

How 275 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 660 buildings in this neighborhood, 271 are predicted to be safer.
