Initial analysis

The 492-496 28th Avenue property is a two-story mixed-use building constructed in 1922 in San Francisco's Central Richmond neighborhood, containing 4 residential units and ground-floor commercial space. The building has undergone several significant renovations and maintenance projects over the years, with the most recent major work being a $40,000 improvement project in 2016 that included window replacements, bathroom fixture updates, water heater relocation, and electrical system upgrades. Notable historical work includes the installation of handicap-accessible facilities in 1998, roofing projects in 1991 and 2016, and the removal of an unauthorized projecting sign in 2000.

The property experienced a cluster of building violations in 2004-2005 related to fire safety and sanitation issues, including concerns about combustible storage, egress obstructions, and the need for fire sprinklers, all of which were abated by May 2005. More recent complaints from 2022-2023 indicate some ongoing maintenance and compliance concerns, including reports of a non-functioning heater (2022) and unauthorized interior work by a contractor (2023). The building underwent a pre-construction electrical inspection in September 2023, and various fire safety violations were recorded in 2008 that required correction. The property has also generated multiple 311 calls in recent months (2024) primarily related to parking meter and transit shelter issues, though these are external to the building itself.

Risk rating

How 492-496 28Th 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.
