1410 21st Ave, San Francisco, CA 94122

The Zinn Family Trust owns this two-unit, two-story multi-family residential building located at 1410 21st Avenue in San Francisco's Central Sunset neighborhood, which was constructed in 1937. The property has undergone several significant infrastructure upgrades in recent years, including a sewer line replacement completed in December 2021 and the installation of a heat pump water heater with associated electrical work in February 2022.

Prior electrical improvements from 2012 included a 125A service upgrade and the addition of dedicated circuits to both kitchen and laundry areas in unit 1412. The building's maintenance history shows attention to basic infrastructure, with records of an electrical service upgrade, plumbing work, dry-rot repairs to the front bay window trim, reroofing, and a sidewalk repair, though specific details about the 1982 permit are not provided. Of particular concern is a housing inspection complaint filed in July 2021 regarding safety issues that included problems with fire escape access, window security bars, and general accessibility issues between the washer and hot water heater.

This complaint is currently listed as not active, though it is unclear whether all issues were fully resolved. The property has experienced recurring issues with street parking, as evidenced by multiple 311 calls about vehicles blocking the sidewalk between 2021 and 2017, though these incidents occurred outside the building proper. Additionally, there were two street cleaning-related complaints in October 2012 regarding loose garbage and hazardous materials, both of which were resolved.
