Initial analysis

The two-unit residential building at 4260 25th Street in Noe Valley, dating back to 1900, has undergone several significant improvements over the past three decades. Most notably, in 2019, the property underwent important infrastructure work with the replacement of the house trap and sewer lateral. Approximately two decades earlier, substantial interior renovations were completed including a comprehensive kitchen and bathroom remodel in 2003 (with associated electrical work), the installation of skylights, and the creation of an interior stairway to the lower level, representing a major investment of $100,000. Earlier improvements from the mid-1990s included both a horizontal addition and a rear remodel featuring bathroom and laundry updates, along with window replacements.

The property has experienced relatively few issues impacting resident quality of life, with the majority of incidents relating to municipal services rather than building-specific concerns. Tree maintenance has been a recurring theme in 311 calls, with multiple reports between 2015-2021 regarding landscaping and empty tree basins, though these are external rather than building-specific issues. The only reported building-adjacent incident was a vandalism case involving a damaged tree in January 2021. Other municipal service calls have primarily related to general street maintenance and waste management, with all cases documented as resolved. A standard temporary moving sign request was successfully processed in 2015, indicating no unusual complications with resident transitions.

Risk rating

How 4260 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.

Neighborhood percentile

Out of 1879 buildings in this neighborhood, 864 are predicted to be safer.
