Initial analysis

The property at 750 39th Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1925, currently owned by Mo Young Wong Chong Survivo. The building's structural integrity has been addressed through several significant improvements over the years, including foundation bolting and stucco repair work completed in 1991, with earlier garage-level seismic upgrades attempted in 1990 (though this permit ultimately expired), and more recent renovations in 1996 that involved replacing stucco, changing windows, and other front modifications.

The most recent documented issues at the property have been related to parking violations, with multiple cases of driveway blocking reported in 2023 (January, August, and December), though these were promptly addressed through citations and enforcement actions. Between 2019 and 2023, there have been a few other municipal service calls in the vicinity, including a pavement defect report in 2019 and a sign repair request in 2013. While the building has experienced periodic maintenance and administrative issues typical for its age and location, there are no recorded safety incidents or major structural concerns in the recent history that would impact resident safety or comfort.

Risk rating

How 750 39Th 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
