Initial analysis

The three-unit, three-story multi-family residential building at 115-117 Sanchez Street, located in the Duboce Triangle neighborhood, was constructed in 1906 and is currently owned by Tom Jun Kwock & Wai Kuen. The property has undergone several renovation projects over the years, with the most recent significant work occurring in 2015, including bathroom tile repairs and kitchen cabinet replacements in multiple units. However, more concerning issues have emerged in recent years regarding unauthorized construction activities. There are active unresolved complaints from 2018-2020 about unauthorized room additions and a suspected roof deck installation, with allegations of potential fire hazards due to unpermitted work. The building has a history of maintenance issues, including multiple violations in 2011-2013 related to water damage, mold, and lead paint hazards that were eventually resolved. Earlier violations from 2002 related to fire safety concerns about security bars and fire escape ladders were also resolved, along with various building permits for routine maintenance and repairs.

The property has experienced several infrastructure and safety concerns over the past two decades, including a 2011 water leak incident in an extended kitchen area, various bathroom maintenance issues, and unauthorized construction work. Historical records show proper attention to resolving most cited violations, though the recent complaints regarding unpermitted construction work remain a significant concern. The building's exterior has faced occasional issues such as graffiti, with the most recent case being recorded in December 2023. The property has undergone periodic interior improvements, with multiple permits issued between 2013-2015 for various repair and renovation projects across different units, suggesting ongoing maintenance efforts by the property owners despite the recent concerns about unauthorized construction activities.

Risk rating

How 115-117 Sanchez 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
