Initial analysis

The Tran Family Trust owns this three-story, two-unit multi-family residential building located at 543-545 23rd Avenue in the Central Richmond neighborhood, which was constructed in 2005. The building's permit history shows several significant renovation and construction phases between 1997 and 2005, including bathroom remodels, roofing work, and electrical installations, with the final construction phase completed in 2004-2005 involving installation of a 200-amp electrical service and extensive wiring work. Multiple permit-related violations occurred during the construction period, including issues with framing work and excavation without proper permits in 1999-2002, though these were eventually resolved.

The property has experienced several maintenance and safety concerns over its history, particularly during the construction period when there were reports of hazardous conditions including broken and uneven front stairs without handrails in 2002, and construction debris in the front yard. More recent history shows persistent issues with illegal parking, particularly sidewalk parking, with numerous documented incidents between 2019 and 2024, suggesting ongoing challenges with parking enforcement in the area. There was also an allegation in 2011 regarding unauthorized conversion of a non-inhabitable building into a living space, though this complaint is noted as not active. The most recent documented issues have been parking-related, with multiple incidents of vehicles blocking sidewalks or double parking, with the last reported incident in December 2024.

Risk rating

How 543-545 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.

Neighborhood percentile
