3624-3626 20th St, San Francisco, CA 94110

The property at 3624-3626 20th Street is a two-unit, two-story multi-family residential building located in the Mission Dolores neighborhood. Built in 1907 and currently owned by the Cline Jacqueline Rev Liv Trust, this flats and duplex structure has undergone several significant improvements over the past three decades. The most recent major works include window replacements in 2021 and 2019, focusing on both front and rear windows with specific aesthetic features; a comprehensive kitchen remodel in 2016 that included updates to the laundry room and pantry with associated plumbing and electrical work valued at $45,000; and reroofing projects conducted in 2014 and 2001.

The building's electrical system received upgrades in 2017 with a complete rewiring of the kitchen, pantry, and laundry areas, including the installation of a new sub-panel, while plumbing improvements during the same period involved new drainage and water lines. The property has maintained a relatively orderly record with no major incidents affecting resident safety or comfort. Recent 311 calls primarily relate to external issues not directly affecting the building's habitability, such as park violations, driveway blocking, and street defects.

While there have been multiple reports of graffiti, defaced signs, and other minor neighborhood issues in the vicinity, these have all been resolved through appropriate city channels. Notably, there was an expired permit from 1995 for installing a half bath in the basement of an illegal unit, which suggests this unauthorized modification was not completed or has been otherwise addressed. The building's maintenance history shows regular upkeep and modernization, with particular attention paid to preserving historical details, as evidenced by the specific requirements of the window replacement projects.
