Initial analysis

The 6-unit, 2-story apartment building at 2840 25th Street in the Inner Mission, managed by the Helen Kong Trust, has undergone several significant improvements since its construction in 1914. Most notably, a mandatory soft-story retrofit was successfully completed in 2017 at a cost of $70,000, bringing the building into compliance with seismic safety requirements under SFBC Chapter 4D. The building received substantial electrical system upgrades in 2003 with the installation of 7-60 amp electric meters, indicating modernization of the power distribution system. More recent infrastructure improvements include various street space permits in 2020, 2018, and 2010, though their specific impacts on the building are minimal.

The property experienced several maintenance issues in late 2024, with eight separate reports of garbage and debris problems between November and December, including incidents of overflowing city garbage cans and other waste. These sanitation challenges appeared to be primarily street-related rather than directly linked to the building's interior conditions. The building’s maintenance history includes various historical permits such as a reroofing project from 1997 (which expired) and a door replacement project from 1984 (which was cancelled). A water service request was logged and resolved in November 2024, requiring basic troubleshooting of fixtures. The property appears to be generally well-maintained from a structural standpoint, with the most pressing recent issues being related to street cleanliness rather than building infrastructure or safety systems.

Risk rating

How 2840 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.
