Initial analysis

The Fong Family Trust owns this two-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1911, the property has experienced significant maintenance and infrastructure challenges, particularly related to its plumbing systems. Between 2005-2007, there were multiple instances of raw sewage issues affecting the sidewalk and street areas, with the most recent plumbing problems documented in complaints filed in May 2007 still showing as "Active." The building's maintenance history includes several permits for critical infrastructure work, such as driveway repairs, sidewalk improvements, and sewer line inspections in October 2007, though many of these permits are now expired. There were also serious interior maintenance issues documented in 2005, including water damage, electrical problems, and structural concerns, which resulted in multiple violations with final warning letters issued in May 2005. These violations addressed various hazards including lead paint concerns, damaged ceilings, light fixtures, stairs, windows, and fire safety issues.

The property has undergone some electrical and plumbing work in recent years, including an underground conversion completed in 2005 and various permit applications. More recently, between 2020-2024, there have been several maintenance and parking-related issues noted through 311 calls, including reports of vehicles blocking driveways and bicycle lanes, though these are primarily external to the building itself. The most recent building-related complaints were resolved or closed between 2020-2023, including issues with the building's sign and some street maintenance matters. While some historical plumbing and maintenance issues have been addressed, the presence of multiple active violations from 2005-2007 suggests that there may be ongoing or unresolved building systems concerns, particularly related to the plumbing infrastructure.

Risk rating

How 1406-1408 6Th 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.
