Initial analysis

The two-unit, two-story multi-family residential building at 635 Frederick Street, owned by the Dalia Becerra 2008 Trust, has been on record since 1910 and has undergone several significant maintenance and safety-related events over the years. Most concerning is a recent complaint filed in March 2024 regarding rotting front steps that presents potential safety hazards, particularly for vulnerable residents including young children and older adults. This is not the first time stair safety has been an issue; previous records show a stair repair project in 1996 and a stair replacement project in 2012, suggesting a recurring problem with this safety feature. In June 2010, the building faced several fire safety inspections where issues were reported with fire extinguishers (corrected), alarm systems (no merit), and blocked exits (referred to another agency), though no civilian injuries were recorded in any subsequent fire incidents. The building has experienced four documented fire-related incidents, all of which had no civilian injuries, including three false alarms or malfunction calls and one contained cooking fire.

Recent neighborhood activity around the property has been notable, with multiple reports of overflowing city garbage cans and other debris issues in January 2025, though these appear to be primarily street-level concerns rather than building-specific problems. A 1998 reroofing project and the aforementioned stair-related improvements represent the major structural maintenance work performed on the building over the past few decades, while the various fire safety inspections and incidents suggest ongoing attention to safety systems has been necessary. The building's location has recently experienced multiple reports of trash-related issues, with Recology responding to several cases of overflowing garbage, and there remains an open issue regarding graffiti on a fire hydrant as of January 2025.

Risk rating

How 635 Frederick 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.
