1227 16th Ave, San Francisco, CA 94122

The two-unit residential building at 1227 16th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1926 and currently owned by Lop Cho & Lui Sui Kuen Youn. The property has experienced several significant maintenance issues over the past decade, with the most notable concerns occurring in 2018 when multiple violations were recorded in April relating to stair repairs, fire safety equipment, and smoke/carbon monoxide alarm requirements.

These violations, stemming from complaints about wood fire escape stairs and possible structural issues, were ultimately resolved by July 2018 through the completion of repair work on the stairs. More recent improvements to the property include electrical upgrades in 2021-2022, with the installation of additional meters and a 200-amp upgrade, suggesting infrastructure modernization efforts by the current ownership. Earlier concerns about the building's condition were documented in 2014, when there was a complaint regarding rotted stairs on the building's south side, and in 2016, when a tenant raised questions about unit legality, window security, exit accessibility, and rodent issues.

The building's maintenance history shows attention to basic upkeep, including a reroofing project completed in 1991 and basement remodeling work from 1983. The property has also experienced some neighborhood-related issues as documented in 311 calls, primarily related to parking violations and street cleaning matters, though these are external to the building's structural and safety concerns. The most recent activity at the address includes parking enforcement requests from 2024, though these are not directly related to the building's condition or safety systems.
