Initial analysis

The two-unit multi-family residential building at 726-728 27th Avenue in Central Richmond is a 2-story flats and duplex structure built in 1924, currently owned by William A and Sarah T Cole. The property underwent significant renovations in 2009, including comprehensive kitchen and bathroom remodels in both units, electrical upgrades with new garage lighting, two sub-panels, laundry facilities, and the installation of multiple modern appliances. Major improvements also included window retrofitting, wooden stair repairs in the lightwell, and HVAC updates with new furnaces and ductwork, totaling over $75,000 in construction costs. Earlier maintenance records show the building received a new roof in 1996.

The property has experienced recurring issues with driveway access, with multiple parking enforcement calls recorded between 2023 and 2024, though these are external matters unrelated to the building's condition. Out of the 15 parking complaints logged, 10 resulted in citations being issued, while others were either invalid or officers were unable to locate the vehicles in question. The building's documented history shows no reported safety violations or maintenance issues in recent years, with the 2009 renovations appearing to have modernized and maintained the property to current standards.

Risk rating

How 726-728 27Th 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

Out of 2250 buildings in this neighborhood, 1058 are predicted to be safer.
