Initial analysis

The 4-unit, 2-story multi-family residential building at 1777 7th Ave in the Inner Sunset, owned by Kung Lin Chia, was constructed in 1955 and has undergone several significant maintenance and repair projects over the past three decades. Most recently, in early 2024, the building experienced heating system issues leading to complaints about foul odors and carbon monoxide detector alerts, which resulted in the replacement of two furnaces and associated ductwork at a cost of $13,000. The building has a documented history of maintenance work including window replacements (1998), retaining wall repairs (1999), reroofing (2005), and various routine inspections.

The property has faced multiple safety-related violations over the years, with the most recent heating system maintenance complaint filed in January 2024. Historical violations from 2018 and 2010 included concerns about fire extinguishers, security devices, self-closing doors, and handrail requirements, though all were eventually resolved. The building's infrastructure maintenance continues to be addressed proactively, as evidenced by the recent furnace replacement work. External to the building itself, there are currently two open infrastructure issues from 2023-2024 regarding pavement and sidewalk defects, though these relate to public infrastructure rather than the building's structural systems. The property has experienced minimal fire-related incidents, with only one recorded water or steam leak situation and no civilian injuries.

Risk rating

How 1777 7Th 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.
