1426-1428 18th Ave, San Francisco, CA 94122

The property at 1426-1428 18th Avenue in San Francisco's Inner Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1925, currently owned by Tung Wai Yip. The building underwent a significant condo conversion process in 2016, which was completed with associated plumbing and electrical work, converting the two flats into condominiums and following DPW's lottery bypass requirements.

Prior to this conversion, the building had several maintenance issues addressed between 2010 and 2012, including termite damage repairs costing $12,700 in 2012 and dry rot repairs to the front wall in 1990, along with a furnace replacement in 2010. The most recent building-related activity occurred in June 2023, when a permit was filed to change the use of a retail space to a restaurant without physical modifications. The property has experienced various neighborhood incidents documented through 311 calls, primarily related to parking enforcement issues, including multiple citations for driveway blocking and sidewalk parking between 2018 and 2024.

Other neighborhood concerns have included tree damage incidents in 2018 and 2022, graffiti in 2021, and a resolved encampment item in 2022. While these external incidents may impact the general area around the building, they are primarily neighborhood issues rather than building-specific problems. The building's maintenance history shows attention to structural and pest issues, with no recent building-specific complaints or violations on record.
