3658-3660 Mission St, San Francisco, CA 94110

The three-story multi-family residential building at 3658-3660 Mission Street in Bernal Heights, owned by Vincent Yu, consists of two units and was constructed in 1965. The property has undergone several significant renovations over the past decade, with the most substantial work occurring in 2017, when major modifications were completed to improve accessibility and functionality, including the relocation of various rooms and utilities, installation of new bathrooms, and creation of additional living spaces. This included $55,000 worth of improvements to add storage, entertainment, and laundry facilities, followed by revisions to optimize hallway spaces and door openings.

The building's infrastructure has been systematically updated, with particular attention to utility systems - water heaters and furnaces were relocated, new electrical systems were installed, and plumbing infrastructure was modernized, though some permits from this period show as expired. The property's maintenance history includes a 2009 sewer repair completion and a kitchen remodel in 2007 valued at $23,000. A notable building complaint was filed in December 2016, shortly after new ownership, regarding unpermitted work and safety concerns, though this complaint is currently listed as not active.

The location has experienced recurring issues with driveway blocking, particularly on public holidays, with multiple citations issued between 2021 and 2025, though these are not directly related to building conditions. Recent 311 calls from 2023-2024 primarily concerned street maintenance issues such as pavement defects and general cleaning needs, with one instance of graffiti reported in December 2021 that was subsequently resolved under emergency legislation. The building's permit history indicates regular upkeep and modernization efforts, including a rooftop replacement in 2001, and various electrical upgrades including an underground service conversion in 2003. The majority of recent improvements have focused on enhancing the building's functionality and accessibility, with completed permits showing responsible management and compliance with building codes, despite the initial complaint in 2016.
