1577-1579 10th Ave, San Francisco, CA 94122

The property at 1577-1579 10th Avenue in San Francisco's Inner Sunset neighborhood is a two-unit residential building constructed in 1981, currently owned by Chequer Island Trust. The building has been the subject of recent attention regarding unit legalization, with a permit filed in May 2018 to legalize an existing unwarranted ground floor unit under Unit Legalization Ordinance 43-14; this permit is currently listed as "On Hold" in planning records.

The property underwent significant redevelopment in its early history, having previously been a single-family dwelling before a two-story over-garage, two-unit configuration with parking spaces was constructed. Recent activity at the property has primarily involved parking-related issues, with multiple reports of blocked driveways between September 2023 and July 2024, resulting in several citations being issued and failed attempts to locate offending vehicles. There have also been two street cleaning incidents reported in 2024, including one involving human waste or urine and another for loose garbage, though nothing was found in the second instance.

A noise complaint was logged in September 2023, which was determined to be related to aircraft noise control matters handled by the FAA. Historical records from 2009 show two fire complaints regarding unlicensed auto repair and operating without a permit, both of which were determined to have no merit. While the building's recent history shows regular maintenance and enforcement activity, these concerns have been primarily related to exterior property management and parking issues rather than internal building safety or habitability matters.
