3632-3634 Mission St, San Francisco, CA 94110

The two-unit residential building at 3632-3634 Mission Street in Bernal Heights, owned by Zhang Zeyu, is a two-story flats and duplex structure built in 1962. The building's most significant infrastructure update was completed in 2003 with an underground electrical service conversion to a 150-amp two-meter system.

A notable incident occurred with a building fire (ignition cause: unintentional), though no civilian injuries were reported, and the date is not specified in the records. The property has experienced recurring issues with its external environment, particularly in 2021-2023, with multiple reports of sidewalk cleaning needs including loose garbage, human/animal waste, and graffiti on the building in December 2021. Tree maintenance has been an ongoing concern, with reported issues in August 2022 and October 2023 regarding overgrown and property-damaging trees, though the Department of Public Works indicated these would be addressed under the city's regular maintenance schedule.

The most recent incidents include a pavement defect reported in April 2024 and a general cleaning issue in December 2023. A parking enforcement issue was successfully resolved with a citation in November 2021. The building's record suggests regular external maintenance needs, primarily related to street cleaning and tree management, with no reported internal building code violations or resident safety issues beyond the historical fire incident.
