Initial analysis

The two-unit residential building at 1382 39th Avenue in San Francisco's Outer Sunset neighborhood is a two-story flats and duplex structure built in 1951, currently owned by the Zhong Ai Mai Revocable Trust. The property's documented history reveals several maintenance and improvement efforts over the past four decades, including the installation of aluminum windows in 1987 (though this permit expired), replacement of aluminum windows and termite treatment completed in 1988, and a street space permit issued in 2011. A proposed ground floor renovation project from 1988 that included a bedroom, social room, and bath was ultimately cancelled.

The building's immediate surroundings have experienced various infrastructure and maintenance issues, particularly in 2017-2018 when multiple pavement defects were reported and subsequently resolved through city services. The area has also faced some parking-related incidents, with two reports of abandoned vehicles in 2017 and 2023, and a driveway blocking complaint in April 2024, though enforcement officers were unable to locate the reported vehicle in each case. Other municipal services were required for general cleaning in 2017 and a water leak issue in January 2017, which was transferred to the appropriate department for handling. While the building's permit history shows regular maintenance and improvements typical for its age and type, most recent activity has been limited to street and parking-related issues rather than any building-specific concerns.

Risk rating

How 1382 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
