Initial analysis

The 4-unit, 2-story multi-family residential building at 780 9th Avenue in San Francisco's Inner Richmond neighborhood, owned by Michael Ching, was constructed in 1924 and has undergone several significant maintenance and improvement projects in recent years. Most notably, the building underwent major repairs in 2012-2013, including the reconstruction of stairs in the light well ($7,000), floor joist sistering work ($4,000), and window replacements at the front facade ($5,000), with associated plumbing and electrical work completed in June 2013. The building's most substantial recent concern arose in May 2017 during an annual routine inspection, where multiple violations were documented including issues with smoke detectors, carbon monoxide alarms, interior wall conditions, and fire safety features, though all of these violations were abated by August 21, 2017. The property has maintained regular inspection history with annual routine inspections noted in 2002, 2010, 2017, and the most recent building complaint for construction hours in 2020. Two 311 calls were recorded in 2019 and 2020, one regarding driveway blocking and another for street maintenance, both of which were resolved or transferred to the appropriate department. While the building has experienced various maintenance and compliance issues over the years, records indicate that violations have generally been addressed in a timely manner, with no active violations currently on record.

Risk rating

How 780 9Th 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
