577 21st Ave, San Francisco, CA 94121

The two-unit residential building at 577 21st Avenue in the Central Richmond neighborhood, built in 1983, has undergone several significant renovations and faced some maintenance challenges over the past decades. Most recently, in January 2025, a substantial re-roofing project valued at $24,000 was permitted.

The building has seen multiple window and door upgrades, with a major window replacement project in March 2018 involving front windows, sliding glass doors, and rear windows, though a subsequent permit filed in October 2018 to replace two front windows was cancelled. Earlier improvements included kitchen and bathroom remodeling for both units in 2002, and a complete roof replacement in 2001. The property has experienced some concerning issues, most notably a rodent/insect infestation reported in February 2018 that was transferred to the Department of Public Health for investigation.

There have been recurrent parking enforcement issues in the vicinity, particularly in 2018, with multiple citations issued for sidewalk parking violations. While these incidents primarily involved vehicles from the area rather than residents, they represent a pattern of parking-related concerns in the immediate vicinity of the building. The building's history shows one significant cancellation - a proposed three-story addition in 1990 that did not proceed - and records indicate the site was previously cleared in December 1982 prior to the construction of the existing structure.
