129 Henry St, San Francisco, CA 94114

The two-unit residential building at 129 Henry Street in the Duboce Triangle, owned by John D Moriarty 2012 Revocable Trust, is a two-story flats and duplex structure built in 1902. The property's history reveals several significant maintenance and infrastructure issues, particularly in 2021 when there were documented sewer problems including a sewage backup and a water leak involving the house-to-property connection, for which the property owner was deemed responsible for repairs.

The building has undergone various permits and modifications over the years, including a completed horizontal addition in 1997 and multiple sidewalk permits, though some earlier permits from the 1980s have expired. Recent incidents near the property between 2020 and 2025 highlight ongoing maintenance and environmental challenges in the vicinity. These include multiple instances of parking violations on the sidewalk, graffiti, and reports of garbage and debris on public property.

The building had two combustible materials fire complaints in October 2012, which were resolved by March 2015, though there was also a hazardous condition incident recorded with no civilian injuries. Additionally, there have been several tree-related concerns reported between 2020 and 2022, including one case where a tree was reported to be damaging property, though an arborist inspection determined it was clear of the building. The most recent work on record was a sidewalk permit issued in 2008, suggesting limited recent external modifications to the property.
