Initial analysis

The two-unit residential building at 3869-3871 25th Street in Noe Valley is a two-story flats and duplex structure built in 1890, currently owned by Bonny Wong. The building has undergone several significant renovations and maintenance work over the decades, with the most recent substantial work being completed in 2020 when new Hardie cement board siding was installed on the building's left side at a cost of $12,000. Other major improvements include an electrical underground conversion and grounding upgrade in 2004, complete roof replacement in 1996, and dry rot repairs in 1984. Two notable permit applications from 1998-1999 for a private parking garage and basement additions were cancelled, and a 1983 foundation work permit expired without completion.

The property has experienced various maintenance and infrastructure issues in the surrounding area over recent years, including several street and sidewalk defects, tree maintenance needs, and occasional encampment-related incidents (most recently in 2022). Noteworthy external improvements include tree pruning in 2019 due to damage, and the removal of a damaged tree the same year. Multiple infrastructure issues have been documented through 311 calls, including pavement defects (2022), graffiti (2021), and hazardous materials (2018), all of which were resolved through appropriate city interventions. While these issues occurred in the immediate vicinity and not directly within the building, they provide context about the surrounding environment. The most recent significant external improvement was tree pruning scheduled for January 2019, and the property remains subject to ongoing maintenance requirements typical for a building of its age and type.

Risk rating

How 3869-3871 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.
