Initial analysis

The two-unit multi-family residential building at 1764-1766 Mission Street, constructed in 1906, has experienced numerous maintenance and safety concerns throughout its history, with particularly significant issues in the early 1990s when multiple complaints documented severe problems including a leaking roof, caved ceilings, electrical issues, and lack of basic utilities. Recent concerns remain notable, with the most recent filed complaint in October 2023 reporting exposed wiring and structural problems in the commercial portion of the building, though this case was marked as not active. The building has undergone various repairs and improvements, including a significant 2010 project costing $9,000 that involved replacing drain pipes and repairing water damage in both residential and commercial areas. The property has experienced concerning maintenance patterns, with multiple complaints about unauthorized construction work, including a 2016 report of unpermitted plumbing and electrical work being performed during early hours.

Recent inspections and complaints have indicated ongoing safety concerns, including a fire code violation issued in August 2023, though previous violations have typically been abated. The property underwent various improvements in the 1990s and 2000s, including the installation of a fire escape ladder in 2000 and multiple utility upgrades. Recent months have seen multiple reports of graffiti, hazardous materials, and abandoned vehicles in the vicinity of the property, along with unpermitted construction work complaints. The building's history shows a pattern of maintenance issues being addressed through various permits and repairs, though the relatively recent complaints about exposed wiring and fire code violations suggest ongoing concerns with building safety and maintenance. The property's commercial space has been the subject of several regulatory actions, including a recent fire code violation in 2023, while the residential units have experienced varying degrees of maintenance and compliance issues over the years.
