Initial analysis

The property at 2388-2390 40th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Outer Parkside neighborhood, built in 1957 and currently owned by the Zeng Family Trust. The building has undergone several significant improvements over the years, most notably a comprehensive kitchen remodel in 2020 that included cabinet replacement, appliance installation, and electrical upgrades at a cost of $22,000. Earlier renovations include bathroom upgrades in 2006 with new tiles and fixtures, window replacements in 2004, and reroofing work in 2012. While the building experienced some regulatory issues in 2006 regarding unauthorized bathroom remodeling work, these violations were eventually abated in 2011. The property has had minimal recent maintenance issues directly affecting resident quality of life, with most documented service calls relating to street cleaning and parking enforcement matters outside the building's direct purview.

The most recent building improvements (2020) and the property's otherwise maintained record of repairs and upgrades suggest regular upkeep by the current ownership. Historical violations from 2006 regarding unpermitted construction were addressed through proper permitting and inspections in subsequent work, indicating improved compliance with building regulations. The building's documented history shows no recurring patterns of maintenance neglect or safety concerns, with most unit improvements focusing on modernization of facilities rather than addressing persistent problems. The surrounding area has experienced typical urban infrastructure issues such as street cleaning and parking concerns, though these have been handled by appropriate city agencies and do not reflect on the building's condition or management.

Risk rating

How 2388-2390 40Th 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.
