Initial analysis

The two-unit residential building at 1639 9th Avenue in San Francisco's Inner Sunset neighborhood, owned by Elissa Epel and John Glaser Family Trust, has experienced several notable maintenance and compliance issues over the past decade. Most recently, in May 2024, there was an active complaint regarding potential unauthorized work and an illegal unit in the garage, though this complaint remains unaddressed in the current records. The property has a documented history of addressing dry rot and water intrusion issues, with multiple repair projects between 2022 and 2024, including dry rot repairs at front exterior stairs (completed in January 2024) and various deck repairs. The building underwent significant maintenance in 2022, including reroofing and window replacement work, while earlier maintenance included a solar panel installation in 2009 and electrical upgrades in 2003. The property has experienced multiple sewage backup incidents, with reported cases in 2022 and 2021, and has faced some complaints regarding waste management and shared spaces in late 2022. Historical records show the building was converted from single-family to multi-family use in 1997, with various structural and maintenance work performed over the years, including a cancelled horizontal addition in 2001 and deck-related repairs dating back to 2002. The property has maintained regular maintenance patterns, though the recent active complaint regarding unauthorized work suggests potential ongoing compliance issues.

Risk rating

How 1639 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

Out of 1493 buildings in this neighborhood, 105 are predicted to be safer.
