Initial analysis

The property at 4422-4424 23rd Street in Noe Valley is a two-story, three-unit multi-family residential building constructed in 1903 and currently owned by Chow Kit C. The building has undergone several significant improvements over the past two decades, with the most recent major works involving window replacements in 2013 and 2015, including both street-visible wood windows and non-visible vinyl replacements. Other notable improvements include a 100-amp electrical service upgrade with individual meters for each unit in 2011, exterior stair and deck repairs in 2002, and a regular housing inspection in 2011.

The building's maintenance history shows attention to safety concerns, particularly in response to a 2002 violation notice that resulted in the installation of proper fire safety equipment and repairs to stairs used for emergency egress. The property experienced some infrastructure issues in recent years, including water leak concerns in 2021 and multiple parking-related incidents near the property. Two significant tenant buyouts occurred in March and January 2021, each for $50,000 involving two tenants. The building has also been subject to routine inspections and has maintained active compliance with building codes since the 1986 "to bring into code" improvements. While there have been various 311 calls regarding the property, these mostly relate to external factors such as sidewalk issues and parking concerns rather than building-specific problems.

Risk rating

How 4422-4424 23Rd 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, 1146 are predicted to be safer.
