Initial analysis

The two-unit residential building at 704-706 24th Avenue in San Francisco's Central Richmond neighborhood, owned by Lau Jung & Ong Jolly Ann, was constructed in 1947 and has undergone several significant maintenance and repair projects over the past two decades. Most recently, in 2018, the building's electrical service was upgraded to a 200-amp system to accommodate two residential meters, and a minor street space permit was issued. In 2012, the building suffered vehicle damage to its northwest corner, requiring window replacement, though this incident was promptly addressed and the building was confirmed safe for occupancy. Earlier maintenance included a roof replacement in 2007, which had initially been performed without the required permits, leading to a violation that was ultimately resolved.

The property has experienced various maintenance incidents requiring municipal attention, particularly in 2023-2024, with several reports of garbage and debris on or near the property, though all these issues were promptly addressed and resolved. A water-related issue was reported in December 2024, determined to be ground water only. The building's maintenance history shows regular upkeep, with the 2007 roof work, 2011 gas pipe repair, and 2018 electrical upgrade indicating attention to essential infrastructure. The property has had two notable violation events on record: unauthorized reroofing in 2006 that required retroactive permitting, and a vehicle-related building damage incident in 2011, though both issues were ultimately resolved through proper remediation and compliance processes. The building's systems appear to have been regularly updated, with significant improvements made to both the electrical and roofing systems over time, suggesting a pattern of responsible maintenance by the current owners.

Risk rating

How 704-706 24Th 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.
