160-162 21st Ave, San Francisco, CA 94121

The two-unit residential building at 160-162 21st Avenue, currently owned by Chung Trust, is a two-story flats and duplex structure built in 1921 in the Lake-Presidio neighborhood. The property has undergone several significant maintenance and compliance issues over its history, with the most recent major incident occurring in 2019 when drainage problems from the property caused water damage to a neighboring building, leading to violations that were ultimately resolved by May 2019.

In late 2008, the building received multiple housing code violations related to security (including garage door self-closing mechanisms and lock requirements), fire safety, and plumbing issues, all of which were addressed through various repairs and replacements totaling approximately $2,000, including work on doors, steps, locks, and electrical systems. The building has a documented history of foundation work from 1997, including foundation bolting and panel upgrades, as well as repairs to address dry rot and code violations, indicating attention to structural integrity.

Earlier improvements were made in 1984, including bathroom additions and ceiling height adjustments. More recently, there have been multiple parking-related complaints near the property (2019-2024), though these are not directly related to building conditions. The property appears to have maintained compliance with building codes since the resolution of the 2019 drainage issue, with no active violations on record as of the latest available information.
