Initial analysis

This two-unit residential building, located at 3433 25th St in the Inner Mission and owned by Kai Bansner, is a two-story flats and duplex structure built in 1900. The building's maintenance history shows several significant issues in 1997, when multiple complaints were filed through Housing Inspection Services regarding water damage, including leaks under the kitchen faucet, water-damaged walls in both bedrooms and kitchen areas, and pest issues with roaches, all of which were officially abated by July 17, 1997. During the same period, two building permits were issued for works related to these problems: one for reroofing (completed in April 1997) and another for removing plywood around stairs and kitchen areas.

More recently, in September 2023, there was a sewage backup incident that was promptly resolved by the PUC Sewer Operations team. Between 2020 and 2023, there have been numerous street cleaning-related incidents recorded, primarily involving loose garbage, though these are external to the building itself and fall within normal urban maintenance patterns. The property has demonstrated stability since the 1997 repairs were completed, with no recurring internal issues reported, and the most recent building activity has focused primarily on routine maintenance rather than significant repairs or remediation work.

Risk rating

How 3433 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.
