Initial analysis

The property at 4346-4350 25th Street in Noe Valley is a 2-story, 4-unit multi-family residential building constructed in 1908, currently owned by the Kwock Family Revocable Trust. The building has undergone several significant maintenance actions over the years, with the most recent major issues including a sewage backup discharge from the side sewer vent in November 2024, and a parking enforcement incident in March 2024 involving a sidewalk parking violation. The building's plumbing infrastructure has received attention in recent years, with completed work in 2011 installing a new gas line and house trap repairs performed in 2010.

The property experienced multiple housing code violations in 2005, including issues with weatherproofing on siding, self-closing devices at exterior doors, and egress obstruction at the rear door, all of which were resolved by May 2005. Historical records show earlier maintenance work in 1986 related to rot repair in the front stairway landing. The building has undergone routine apartment house inspections over the years, with the most recent inspection recorded as active in 2010. More recent records from 2021-2024 primarily consist of external service calls regarding parking enforcement and street cleaning, rather than internal building issues, suggesting that while there were historical maintenance concerns, there have been no similar pattern of violations or major repairs in the past decade.

Risk rating

How 4346-4350 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
