The 326-328 20th Avenue property is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1923 and currently owned by Ludmila & Yakov Klachkovsky, this flats and duplex style building has undergone several significant improvements over the past decade.

Most notably, in 2018, the property received substantial window upgrades, replacing six non-original aluminum windows with energy-efficient wood windows with a U-factor of .32, at a cost of $11,291. Earlier renovations in 2016-2017 included comprehensive kitchen and bathroom remodeling work, involving the replacement of plumbing and electrical systems, installation of new fixtures, and upgrade to a 200-amp electrical service, totaling approximately $22,000. The building's maintenance history shows attention to both interior modernization and exterior preservation, with a street space and sidewalk repair permit issued in 2010, and no recorded building violations or occupancy issues.

The property has had minimal external issues reported through 311 calls, with only three incidents related to parking violations on the sidewalk (in 2018 and 2019) and one general cleaning complaint in 2021, none of which directly impacted the building's condition or resident safety. All permitted work has been completed successfully, with no outstanding violations or permits. The documented improvements demonstrate a pattern of proactive maintenance and upgrading of both the building's interior systems and exterior features, suggesting responsible ownership and attention to property upkeep.
