Initial analysis

The property at 1290-1292 41st Avenue in San Francisco's Outer Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1948, currently owned by Wong Yung Wai. The building has undergone several significant maintenance activities, most recently including an approved $12,000 reroofing project in September 2024, following a previous roofing project from 1995 that expired. The property experienced various infrastructure and maintenance challenges in 2024, with notable incidents including a sewage backup from a side sewer vent in September, pavement defects (open as of October), and multiple tree-related complaints regarding property damage, though these were ultimately cancelled due to citywide resource allocation under Prop-E.

The building's street-facing issues have been numerous in 2024, with multiple reports of illegal parking, including vehicles on sidewalks, though enforcement officers were often unable to validate the issues upon inspection. Environmental concerns include a June 2024 report of garbage and debris, specifically relating to an abandoned refrigerator, which has since been resolved. Interestingly, there appears to be some discrepancy between the building's two-unit designation and a tenant buyout record from July 2023, which shows the vacating of two tenants at an adjacent address (1274 41st Avenue) for $14,000. The property has experienced a malfunctioning alarm system incident, though no civilian injuries were reported.

Risk rating

How 1290-1292 41St 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
81th percentile

Out of 632 buildings in this neighborhood, 120 are predicted to be safer.
