3532-3534 21st St, San Francisco, CA 94114

This two-unit multi-family residential building, located at 3532-3534 21st Street in the Eureka Valley/Dolores Heights neighborhood, is a two-story flats and duplex structure built in 1901 and currently owned by James & Jo Anne Callaghan T. The property's maintenance history reveals several significant improvements over the years, including a complete window replacement project in 2008 costing $8,400, where seven street-visible windows were upgraded to Marvin wood clad windows.

The building has undergone two roofing projects, with the most recent completed in 1995 (while one from 1997 shows as expired). In 2004, there was an electrical infrastructure upgrade with an underground service conversion to support two existing 100-amp meters. The building has experienced some notable service issues in recent years, including a sewage backup incident in August 2012 that required field work by PUC Sewer Operations to resolve.

More recently, there have been several municipal service interactions, including two Muni-related complaints in 2020-2021 regarding vehicle maintenance noise and general feedback, as well as a defaced parking sign incident in January 2020. While these external municipal issues indicate some neighborhood concerns, they primarily relate to city services rather than building-specific problems. The property's permit history suggests regular maintenance and upgrading of essential systems, with no recorded building code violations or safety-related incidents in the available data.
