3356-3358 21st St, San Francisco, CA 94110

The property at 3356-3358 21st Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, constructed in 1900. The building has experienced recurring maintenance issues, particularly with the rear stairs, which have required multiple repairs over the years (2003, 2012, and most recently in 2024). A significant recent concern is the documented mold problem reported in January 2023, which was noted as affecting every room in the house and had not been adequately addressed after tenant notification.

More recent permits indicate ongoing maintenance work, including a basement ceiling repair, window glass replacement, and stair repairs totaling $29,000 in 2024, as well as a completed reroofing project in 2023 costing $18,000. The building has a history of various violations and complaints, particularly between 2002-2003, when multiple fire safety and maintenance issues were documented, including problems with the fire escape, stairs, drainage pipes, and combustible storage. These violations were ultimately abated by March 2003.

More recent concerns include a July 2024 complaint about an unsafe back porch and an active general maintenance complaint from February 2024. The property has undergone several infrastructure improvements, including an underground electrical service conversion in 2004 and various repairs to address building code compliance issues. Historical maintenance records show regular upkeep, including re-roofing work, stair repairs, and window replacements, though some past complaints about sanitation issues and graffiti have been recorded through 311 calls. The current ownership under Shirley Dang has maintained the property through various repairs and improvements, with recent focus on addressing water damage and fire safety concerns.
