Initial analysis

The two-unit residential building at 440 28th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1977, currently owned by Howard K & Marilyn P Lew Re. The building has undergone several significant maintenance and improvement projects over the years, with the most recent being a complete re-roofing project in 2017 that cost $13,800. Prior to that, in 2011, major exterior improvements were made including the replacement of 23 double-pane aluminum windows on the front facade and painting of the exterior, with this project valued at $13,000. Historical records show earlier maintenance work from the 1990s, including a reroofing project in 1996 and dry rot repairs in 1993, though these permits have since expired.

The property has experienced recurring sewer-related issues, with documented incidents in two notable clusters. The most recent series of events occurred in late 2017 and mid-2015, with a sewage backup incident on December 26, 2017, and two sewer vent-related problems in June and July 2015. These sewer issues were all addressed and resolved by PUC Sewer Operations, suggesting there may have been some systemic plumbing challenges during that period. While these incidents were properly addressed through municipal services, the frequency of sewer-related problems over the two-year period is worth noting in relation to the building's maintenance history. Since the last reported sewer incident in 2017, there are no further documented plumbing or infrastructure issues on record, and the property has undergone several significant maintenance upgrades in the past decade.

Risk rating

How 440 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.
