Initial analysis

The 6-unit, 2-story multi-family residential building at 484-490 9th Avenue in San Francisco's Inner Richmond district, built in 1911, has undergone several significant improvements and faced multiple compliance issues over the past two decades. Most notably, the building completed a mandatory soft-story retrofit in 2017 (cost: $80,000) and received a new roof in 2021 (cost: $27,850). The property has a documented history of safety and compliance concerns, including a 2017 routine safety inspection that revealed several violations related to smoke detection, carbon monoxide alarms, and security requirements, though all were abated by August 2017. Between 2009-2012, there were unauthorized modifications to the building, including the installation of an illegal bathroom in the basement, which was ultimately addressed through various permits and compliance actions.

The building underwent significant renovations between 2007-2008, including new windows, kitchen improvements, and electrical work (totaling approximately $40,000), and more recent maintenance has focused on structural integrity and safety compliance. A concerning active complaint from 2002 remains on record regarding electrical system reliability and potential asbestos issues, though no recent violations have been reported. The property has experienced minimal emergency incidents, with only one notable event in 2019 involving minor damage to the brick facade from a vehicle collision.

Risk rating

How 484-490 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.
