501-503 Buena Vista Ave, San Francisco, CA 94117

The building at 501-503 Buena Vista Avenue is a three-story multi-family residential structure built in 1939, currently containing three units and owned by Young Dykes M. The property has undergone significant transformations over the past decade, most notably the conversion of ground floor storage space into a third dwelling unit in 2015, which included adding interior stairs to the second floor, and was followed by comprehensive fire safety upgrades.

These upgrades included the installation of a complete fire sprinkler system throughout the ground floor in 2017, with an associated monitoring system, indicating attention to safety compliance. The building has seen substantial interior improvements, including electrical rewiring of various units, kitchen and bathroom remodels, and the addition of modern amenities such as Rinnai heaters.

Recent 311 calls (2024) have primarily concerned exterior maintenance issues, including illegal parking, overgrown trees, and sidewalk blockages, though these do not directly impact the building's structural integrity or systems. The property has also been subject to various planning considerations, including concerns about outdoor lighting affecting a nearby bird refuge and several permits related to recreation equipment maintenance through the Recreation and Parks Department. The most recent activity includes maintenance issues such as overgrown trees and sidewalk blockages from late 2024, which are being addressed through appropriate city channels.
