70-72 6th Ave, San Francisco, CA 94118

The two-unit residential building at 70-72 6th Avenue, owned by Robert A. and Stephanie Jensen, is a two-story flats and duplex structure built in 1904 in the Lake-Presidio neighborhood. The property has undergone several significant improvements and maintenance work over recent years, with the most notable being a complete sewer lateral replacement in December 2022, window replacement project in 2019, and repairs to water-damaged flooring, drywall, and cabinetry in 2014 costing $25,000.

An electrical upgrade was also completed in 2019 to install a new circuit and various fixtures for a non-habitable accessory structure. The building has experienced some maintenance issues, including a reported mold and mildew problem in early 2022, though this complaint was marked as "Closed Accepted" by the Department of Building Inspection. Recent history shows regular maintenance and infrastructure updates, including street space permits in 2019 and a horizontal addition completed in 1998.

The property has had several parking-related incidents in the vicinity, with multiple citations issued between 2021 and 2024 for driveway blocking and sidewalk parking violations. A sewage backup issue was reported and resolved in 2016, and there was a brief period of concern in February 2023 regarding the status of the main building, which was classified as a "commercial/business vacant structure" complaint but was marked as not active. The building's maintenance history suggests regular upkeep by the owners, with significant investments in infrastructure and safety systems, though the presence of periodic moisture-related issues like mold and water damage indicates some ongoing building envelope challenges.
