1501 19th Ave, San Francisco, CA 94122

The property at 1501 19th Ave in the Central Sunset neighborhood is a two-story, four-unit multi-family residential building constructed in 1904, currently owned by Tammy Thuan Zitun Lvg Tr. The building has undergone several significant modifications and improvements over the years, with the most recent being the approval of a new three-bedroom ADU (Accessory Dwelling Unit) in late 2021 at a cost of $271,184. Previous permit applications included a withdrawn 2020 proposal for extensive conversions and additions, including new kitchens and bathrooms in multiple units, and a completed 2007 project replacing rear stairs.

The building has a history of addressing structural and safety concerns, notably with three separate fire safety violations in 2001 that were promptly abated within the month, and a February 1997 repair of dry rot damage to the rear stairs and deck. The property has experienced recurring concerns around potentially unauthorized units, with complaints in 1998, 2001, and most recently in 2016 regarding possible illegal units. A significant building complaint was filed in 2007 about unauthorized construction work beyond permitted scope and safety concerns related to a newly built living space.

Recent maintenance activities include multiple sidewalk defect reports in June 2024 and various cleaning issues being addressed throughout 2023-2024. The building's past also includes several successful improvements, such as window replacements in 1997, ground floor remodeling, and various repairs documented through building permits. Recent 311 calls have primarily been related to external issues such as sidewalk conditions, street cleaning, and graffiti on the mailbox, rather than internal building concerns. One current open issue from October 2023 involves a pavement defect that remains unresolved.
