Initial analysis

The two-unit residential building at 1239-1241 41st Avenue in San Francisco's Outer Sunset neighborhood, owned by Lon D & Emily Suen Randall, is a two-story flats and duplex structure built in 1947. The building's maintenance history shows regular attention to essential systems, including three documented re-roofing projects (1985, 1993, and 2008, with the most recent costing $7,980), as well as stucco repairs to the front entrance completed in 1999. These maintenance records indicate proper upkeep of major structural elements over the decades.

The property has experienced several neighborhood issues documented through 311 calls, with a particular cluster of concerns related to waste management and street cleanliness during 2021-2024. Most notably, there were multiple incidents in early 2021 regarding garbage toter management, including several cases of bins being left out continuously, which resulted in enforcement actions and outreach efforts. More recent issues include two driveway-blocking incidents in April 2023, though enforcement officers were unable to locate the offending vehicles. The most current building-related concern is a pavement defect reported in January 2025. While the street and sidewalk areas have experienced occasional garbage and debris issues (with the most recent cases in March 2023 and December 2024), these appear to be general neighborhood maintenance challenges rather than building-specific problems.

Risk rating

How 1239-1241 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.
