Initial analysis

This two-story multi-family residential building, located at 272-274 4th Avenue in the Inner Richmond neighborhood, was built in 1904 and contains three units. The property has undergone several significant improvements over the decades, including reroofing in 1996, a deck replacement in 1986, and kitchen remodeling in units 272 and 274 in 1988. The building underwent two notable safety inspections in December 2004 and December 2015, during which multiple violations were identified, primarily related to fire safety and emergency preparedness. These violations included missing fire extinguishers, combustible storage issues, and concerns about smoke detectors and vent pipes. All violations from the 2004 inspection were officially abated by March 2005, while the 2015 inspection was resolved by February 2016.

The property has a history of maintenance and compliance issues, particularly regarding waste management and sidewalk cleanliness. There have been multiple 311 calls regarding toters being left out continuously (2010, 2011, and 2015) and various instances of illegal parking on the sidewalk (most recently in 2024). Between 2021 and 2024, there were several street cleaning and parking enforcement calls, indicating ongoing challenges with waste management and parking compliance in the vicinity. While the building appears to be currently free of active violations, the historical record shows periodic safety compliance challenges and maintenance issues that have required attention over the years.

Risk rating

How 272-274 4Th 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.
