Initial analysis

The two-story multi-family residential building at 1400 39th Avenue in the Outer Sunset, owned by Leung Exemption Trust, was built in 1964 and contains 7 units. The property has undergone several significant improvements in recent years, most notably completing its mandatory soft-story seismic retrofit as a Tier 3 building in 2022, which was previously cited for non-compliance in 2021. Recent safety upgrades include a $22,440 fire alarm system upgrade completed in 2024, with associated electrical work completed in November 2023, bringing the building's safety systems into full compliance with current regulations.

The building has experienced various maintenance and compliance issues over its history, with a cluster of building violations and complaints documented in 2017, including concerns about the fire escape, paint maintenance, door seals, weatherproofing, and alarm systems - all of which were abated by August 2019. Other notable improvements include the replacement of 28 exterior windows with Pella Impervia fiberglass units in 2017 (approximately $15,000 project), and historical repairs including reroofing in 1993 and restucco work in 1991. Recent 311 calls from late 2024 have primarily concerned waste management and maintenance of waste receptacles, suggesting ongoing challenges with garbage handling at the property. The building's fire safety history shows several alarm system activations, most of which were either false alarms or system malfunctions, with no reported civilian injuries. A sewer discharge incident was reported in October 2024, which was resolved as an internal issue.

Risk rating

How 1400 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
