Initial analysis

This two-story, three-unit multi-family residential building, located at 1283-1285 17th Avenue in San Francisco's Inner Sunset neighborhood, was constructed in 1981 and is currently owned by Wan Chung Lun & Betty & Eva. The building has experienced several significant maintenance and safety issues over the past two decades, with the most notable concerns occurring between 2001-2009. During routine inspections in 2001, 2009, and 2018, multiple violations were identified, including problems with garbage receptacle placement, fire safety equipment, security features, and the need for various fire safety improvements. These violations were ultimately resolved, with the most recent routine inspection in 2018 being marked as "Not Active."

The building has undergone some improvements, such as the conversion of an existing window to a sliding door in 1983 and reroofing work completed in 2002. More recent history includes multiple tree-related issues (2023-2024) with sidewalk damage concerns, and a sewage backup incident in 2020. There have been four fire alarm-related complaints between 2007 and 2015, all of which were resolved with conditions corrected. Recent 311 calls primarily relate to external maintenance issues like garbage, tree concerns, and street cleaning, with the most recent being a garbage incident in August 2024 that was resolved. The building's documented history suggests a pattern of routine inspections revealing safety compliance issues, most of which have been addressed according to available records, though some tree-related concerns persist as of 2023-2024.

Risk rating

How 1283-1285 17Th 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

Out of 1493 buildings in this neighborhood, 836 are predicted to be safer.
