Initial analysis

The property at 8-10 Henry Street in Duboce Triangle is a 3-story, 5-unit multi-family residential building constructed in 1901, currently owned by Maureen Wong Chen Survivors. The building has undergone several significant renovations over the past decade, with the most recent work occurring in 2019-2020, including kitchen and bathroom remodeling, installation of can lights, window repairs, and various electrical upgrades totaling over $100,000 in improvements. However, there were concerning events in October 2019 when multiple complaints were filed regarding unpermitted interior and exterior work, including dust management issues and worker safety concerns during renovation activities.

The building has a history of maintenance and compliance issues, particularly evident in the early 2000s. In 2002, several fire safety violations were documented, including problems with security bars, combustible storage, and stairs, though these were all abated by October 2002. In 2010, there was a complaint about unpermitted window replacement work on the ground floor, and in 2014, tenants reported heating, weatherproofing, and pest control issues. While most of these violations were addressed, the building continues to show signs of wear and requires regular maintenance, as evidenced by multiple renovation projects focusing on kitchens, bathrooms, windows, and electrical systems over the years. Recent 311 calls from 2024 primarily relate to exterior issues such as street cleaning and graffiti, which, while not directly affecting building safety, indicate ongoing maintenance needs in the immediate vicinity of the property.

Risk rating

How 8-10 Henry 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
