Initial analysis

The six-story, 55-unit apartment building at 3440 25th Street in the Inner Mission, owned by Anthony & Diane Martorana R, has experienced several significant maintenance and safety-related issues in recent years. Most notably, there are currently three open fire violations as of November 2023 regarding sleeping area requirements, alarm system maintenance, and sprinkler system maintenance, along with multiple fire safety concerns between 2022-2023 including blocked exits, fire escape issues, and hazardous materials. The building has a concerning history of elevator problems, with a notable complaint in December 2020 about consistent disrepair impacting accessibility for elderly and disabled residents. The property has undergone various major systems upgrades, including a $65,062 project in early 2024 to install additional fire notification devices and low-frequency sounders in sleeping areas, a 2014 boiler replacement project, and significant electrical and interior renovations in 2003. The building has experienced multiple incidents requiring emergency response, primarily for elevator rescues, water evacuation, and occasional cooking fires, though fortunately no civilian injuries have been reported. Recent maintenance challenges are highlighted by multiple complaints in 2021-2024 regarding boiler permit renewals and recurring issues with debris and waste management outside the building, as evidenced by multiple 311 calls for garbage and sidewalk cleaning between 2024-2025.

Risk rating

How 3440 25Th 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.
