The two-unit residential building at 1247-1249 46th Avenue in San Francisco's Outer Sunset neighborhood has undergone significant improvements and modifications since its construction in 1905. Most notably, a new ADU was added in 2023-2024, creating 798 square feet of living space with kitchen, living room, two bathrooms, and two bedrooms on the ground floor. The property has seen substantial safety upgrades, including a comprehensive fire sprinkler system installation in 2024 and a major volcanic seismic retrofit in 2019 that involved replacing the foundation under the existing crawl space.

Recent maintenance work includes a completed reroofing project in 2023 and electrical system upgrades, including a 200-amp service upgrade in 2020. The building's infrastructure has been continuously updated, with the installation of new plumbing systems for the ADU and fire sprinkler system, including furnace relocation and gas line improvements. Historical records show attention to fire safety, structural integrity, and modern amenities, with all major systems receiving appropriate upgrades.

While there have been some infrastructure-related issues affecting the property, such as tree root damage to the sewer system reported in 2024, these are being addressed through proper channels. The building has experienced minimal complaints or violations, with only one historical complaint in 2012 regarding unpermitted construction work that was quickly abated. The property's recent maintenance history suggests active management and compliance with current building codes and regulations.
