1358-1360 48th Ave, San Francisco, CA 94122

The property at 1358-1360 48th Avenue in San Francisco's Outer Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1909, currently owned by Jessica Ka-yuk Leung. The building is undergoing significant expansion, with two major construction projects filed in early 2020 - one for vertical and horizontal additions to the existing structure, including new bedrooms, bathrooms, and an elevator, and another for the construction of a detached two-story ADU in the rear yard, comprising two bedrooms, two bathrooms, and one kitchen, with an estimated cost of $280,000.

The property has experienced some recent infrastructure issues, including a sewage backup incident reported in September 2023, and there have been multiple reports of parking violations in the vicinity during 2023-2024, with variable outcomes ranging from citations issued to officers unable to locate the reported vehicles. The building's electrical system received an upgrade in 2004 with the installation of a 200-amp service entrance, and the address underwent a change from 1353 to 1358-60 in early 2004.

Planning records reveal a complex history of proposed improvements, including a substantial proposed expansion of approximately 3,639 square feet to the existing building, though some of these plans have been cancelled or placed on hold. The detached ADU project appears to be progressing independently, having received CEQA clearance. The property has generated regular 311 calls primarily related to parking issues, with eight such incidents reported between January and September 2024, suggesting ongoing challenges with parking enforcement in the area.
