Initial analysis

The two-unit residential building at 695-697 39th Avenue in San Francisco's Outer Richmond neighborhood is a 2-story flats and duplex structure built in 1944, currently owned by Billy J Jung and Bo-lai Ng. The building's maintenance history shows significant attention to infrastructure upkeep, including a complete reroofing project in 2003 (approximately $8,000), and the replacement of a ground floor back door and floor tiles with associated dry rot repairs in 2000 (approximately $2,400). More recently, in March 2013, high-efficiency furnaces were installed in both units, demonstrating the owners' commitment to energy efficiency improvements.

The property has experienced periodic maintenance issues typical of older buildings, with multiple permits filed between 2000 and 2009 for various repairs and inspections, including several permit renewals to obtain final inspections, though some of these permits expired before completion. Recent records from 2024-2025 indicate several occurrences of street-related issues near the property, including sidewalk parking violations (multiple citations issued), graffiti on public signs, and various types of street cleaning needs, though these are external neighborhood issues rather than building-specific problems. The only recorded fire-related incident was a false alarm or call with no civilian injuries. The building's permit and inspection history suggests regular maintenance and prompt addressing of required repairs, with no recorded violations or safety concerns related to the building structure itself.

Risk rating

How 695-697 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
