Initial analysis

The two-story multi-family residential building at 600 25th Avenue in the Central Richmond neighborhood, owned by the Kirk & May Leong Trust, was constructed in 1949 and contains four apartment units. The building underwent significant remediation efforts in the early 2000s, following a cluster of violations identified in November 2002 related to safety and security concerns. These violations, all of which were abated by August 2004, included issues with smoke detector placement, stair repairs, security lock requirements for secondary doors, and combustible storage concerns. In 2004, there was an attempt to replace 22 windows, though that permit ultimately expired, and a street space permit was issued in 2006. The most recent significant complaint was filed in September 2023 regarding nighttime staff locking an ADA bathroom, though this issue is currently not active.

The building has experienced recurring issues with illegal postings in the vicinity, with multiple incidents reported between 2020 and 2024, including postings on traffic lights and improper affixation. Parking-related complaints have been a persistent issue, with several reports of driveway blocking incidents between 2021 and 2024. Recent calls for service related to this address primarily involve parking enforcement matters. Regular routine inspections have been conducted, including one in 2009 which was completed in February 2009. The most recent recorded issue related to building maintenance was addressed through routine inspections and resolved in 2004, suggesting that the major safety and security concerns identified in 2002 were effectively remedied.

Risk rating

How 600 25Th 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.
