Initial analysis

The three-story multi-family residential building at 1950-1956 Stockton Street in Telegraph Hill, owned by Tony L Wong 2006 Revocable Trust, was constructed in 1908 and contains 4 residential units. The property has experienced several significant maintenance and compliance issues over the past two decades, with the most recent cluster of problems occurring in 2021. During this period, multiple heating system violations were reported, with tenants experiencing no heat in January 2021 in multiple complaints, which were only resolved by April 2023 through the installation of new wall heaters in units 1954 and 1956 at a cost of $1,200 and the replacement of heaters in both units at a cost of $6,000.

The building has a history of various maintenance and safety compliance requirements, including handrail replacement (also addressed in 2021), and earlier issues with roof structures and stairs. In 2000-2002, there were concerns about roof-related work including a suspended permit for a roof enclosure and stairs, while violations from 2002 included requirements for fire safety equipment, security doors, and gas meter instructions. A 2005 routine inspection was conducted without any notable issues. While the most recent permits show attention to heating system improvements and handrail compliance, the building has experienced recurring patterns of heating system problems, with multiple violations and complaints about inadequate heat during winter months. The property underwent several roof-related works in the early 2000s, including reroofing and stair repairs, though some permits were expired or suspended during this period.

Risk rating

How 1950-1956 Stockton 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

10th percentile

Out of 684 buildings in this neighborhood, 616 are predicted to be safer.
