Initial analysis

The property at 1401-1403 12th Avenue is a two-story, four-unit multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1947 and currently owned by Lee Wilson & Linda Goon, this apartment building has undergone several significant improvements over its lifetime. The most recent major building work was a street space permit issued in October 2015, while a substantial reroofing project was completed in 2008 at a cost of $10,000. Earlier improvements included the replacement of 16 windows in 2004, with some facing the street, valued at $5,600.

The building had a notable violation in December 2001 that resulted in multiple fire safety and plumbing-related citations being issued, including issues with fire extinguisher maintenance and plumbing discharge systems. However, all these violations were promptly addressed and officially abated by March 2002. Since that time, the building has maintained a clean record with no active violations or complaints on file. In recent months (between September 2024 and January 2025), there have been multiple reports (at least ten) regarding garbage and debris on or around the property, though most of these were routine street cleaning matters resolved by city services or Recology. This pattern of reports suggests ongoing waste management challenges in the immediate vicinity, though none directly related to the building's maintenance or habitability.

Risk rating

How 1401-1403 12Th 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.
