724-726 Spruce St, San Francisco, CA 94118

The two-unit residential building at 724-726 Spruce Street in the Lone Mountain neighborhood is a two-story flats and duplex structure built in 1912, currently owned by Eugene & Deborah J Wong. The property has undergone several significant improvements over its history, including three major expansions/renovations between 1985-1988, specifically a remodel of an existing dwelling unit in 1985, followed by horizontal additions in 1987 and 1988.

More recently, in July 2024, the owners initiated a plumbing upgrade with the installation of an 80-gallon heat pump water heater to replace a 40-gallon gas water heater in the garage, marking this as the most recent improvement to the property. The building's maintenance record shows attention to safety features, particularly regarding access infrastructure, as evidenced by back stair repairs undertaken in 2009.

The property has experienced minimal street-related issues, with only three 311 calls recorded between 2012-2018, none of which directly involved the building itself. These calls addressed external municipal matters such as pavement defects, street lighting, and street cleaning, all of which were appropriately resolved by city services. The building's permit history suggests consistent upkeep and modernization efforts by the owners, with particular attention to safety and infrastructure improvements when necessary.
