The two-unit residential building at 142 Hamilton Street in Portola, owned by Truong Thanh, has experienced several maintenance and safety issues since its construction in 1908. The most recent significant concerns occurred in January 2025, involving a sewage backup from the side sewer vent, along with multiple reports of garbage and debris that were subsequently resolved. The property has a history of sanitation and building maintenance violations, particularly in 2018, when multiple complaints were filed regarding rubbish removal, stair repairs, lead paint concerns, and weatherproofing issues, with most of these violations being abated by September 2019.

Earlier issues from the 1990s included concerns about backyard debris and waste, though these were resolved by March 1999. The building's maintenance history shows attention to basic upkeep, as evidenced by a completed reroofing project in 1991. Safety-related complaints have been documented through the years, with fire complaints in 2018 (weeds and grass), 2013 (hazardous materials), and 2011 (blocked exits) all being corrected upon inspection.

Recent 311 calls from late 2024 to early 2025 indicate ongoing issues with garbage and debris management in the vicinity, though most cases have been resolved. The property has experienced recurring concerns with exterior maintenance and sanitation, as evidenced by multiple reports spanning decades, from garbage accumulation to paint deterioration and weatherproofing concerns. While many violations have been addressed through official channels, the frequency and variety of historical complaints suggest a pattern of maintenance challenges requiring regular oversight.
