Initial analysis

The three-unit residential building at 350-352 23rd Avenue, located in San Francisco's Central Richmond neighborhood, is a two-story flats and duplex structure built in 1924, currently owned by Donun Chan & Lily T Chan Lv. The property has undergone several infrastructure improvements over the years, including street space and sidewalk permits in 2014 and 2010 respectively, though a 2002 sidewalk permit and a 1995 reroofing permit are now expired. A significant cluster of building violations was documented in late 2007, primarily during a routine apartment housing inspection, which included issues with stair tread deterioration, combustible storage, exterior door self-closing devices, gas meter instructions, and fire extinguisher maintenance; all these violations were resolved by January 24, 2008. An earlier routine inspection was conducted in 2000 with no noted violations.

Recent activity around the property has been primarily related to parking enforcement, with multiple citations issued between May and August 2023 for driveway blocking violations, with at least four resulting in citations. Other recent incidents include a March 2022 report of human or animal waste on the street/sidewalk and a January 2022 Christmas tree removal request, both of which were resolved. The building's permit history shows regular maintenance and compliance efforts, including a 1984 project to bring the building into code compliance as required by dahi. While the property has experienced various maintenance issues in the past, particularly in 2007, there have been no recorded building violations since 2008, indicating improved maintenance of the property, though the recent pattern of vehicle parking violations suggests ongoing challenges with driveway access management.

Risk rating

How 350-352 23Rd Ave'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.
