Initial analysis

The three-story, six-unit multi-family residential building at 331 9th Avenue in San Francisco's Inner Richmond district, owned by Louie Kelvin and Genevieve Rev, was constructed in 1913 and has undergone significant safety improvements in recent years. Most notably, the building completed a mandatory Tier 3 soft-story retrofit in 2016 at a cost of $80,000, demonstrating compliance with seismic safety requirements. The building's safety record shows a cluster of fire safety violations in 2001, including issues with the central alarm system, fire escape ladders, combustible storage, and lighting, though all these violations were resolved by November 2001. There were also two fire-related incidents recorded, both classified as false alarms, and two fire complaints in 2005 and 2010, with the 2005 alarm systems issue being corrected.

Recent service records from 2021 to 2024 primarily consist of street-level maintenance calls, including reports of garbage and debris, cleaning needs, and a couple of encampment-related incidents outside the building. The property has undergone regular housing inspections, with routine checks recorded in 2001 and 2009, both of which have been marked as not active. While the building's recent history shows no major safety violations or complaints, the external environment around the building has experienced typical urban challenges, as evidenced by the several 311 calls regarding street cleaning and maintenance needs.

Risk rating

How 331 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 1723 buildings in this neighborhood, 1430 are predicted to be safer.
