Initial analysis

The three-unit, three-story multi-family residential building at 939 Jackson Street in Nob Hill, owned by the Fong Family Trust, has undergone several significant maintenance and safety-related improvements since its construction in 1908. Most recently, in November 2024, the building received a new roof at a cost of $13,500. The property has seen substantial system upgrades, including the installation of new gas heaters in all units in 2012 (with associated safety features), the addition of three gas fireplaces, and various stair repairs. The building has undergone regular routine safety inspections, with the most recent significant findings occurring in 2016-2017 when multiple violations were noted, including the need for fire extinguisher servicing, carbon monoxide alarms, and a routine safety inspection of common areas. These violations were ultimately abated by February 2017.

The building has experienced recurring fire safety system issues over the years, with violations recorded for sprinkler systems, alarm systems, and fire extinguishers between 2015 and 2023. The most recent fire safety violation, as of May 2023, was related to sprinkler/standpipe systems, while a 2022 violation concerned the alarm system. The property had its fire alarm system malfunction in 2019 but no injuries were reported. The owner has consistently addressed violations when cited, including a tenant buyout of $15,000 for two tenants in November 2022. Recent maintenance includes regular parking enforcement cases nearby and occasional reports of graffiti and general cleaning issues, though these external matters are usually resolved promptly. The building has maintained its residential classification throughout its history, with routine inspections confirming compliance with housing codes, though past violations have occasionally noted issues with stair repairs, handrails, and garbage receptacle placement.

Risk rating

How 927-931 Jackson St'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
