87-89 Niagara Ave, San Francisco, CA 94112

The two-unit residential building at 87-89 Niagara Avenue in the Outer Mission neighborhood, owned by Co Elsa Dy, has a documented history spanning several decades since its construction in 1913. The property has undergone multiple significant repairs and maintenance work, particularly in the early 2000s, including several permits for window and door frame replacements, wall repairs, and cement work - with costs ranging from $2,000 to $6,000.

Notably, there were two documented complaints regarding hot water issues in April 2002, though these were promptly addressed within a few days. More recent records from January 2025 show multiple parking enforcement actions related to sidewalk parking violations, with at least two resulting in citations, though some cases could not be verified by responding officers.

The property has experienced minimal emergency services involvement, with only three recent fire department responses for non-injury service calls related to medical assistance and a motor vehicle incident. Historical improvements include window replacements and bathroom renovations in 1997, staircase repairs in 1993, and reroofing in 1990. While the building's maintenance history shows regular upkeep, recent concerns primarily revolve around parking violations rather than building-specific issues.
