520-522 2nd Ave, San Francisco, CA 94118

The 2-unit multi-family residential building at 520-522 2nd Avenue in the Inner Richmond district is a 2-story flats and duplex structure built in 1905 and currently owned by Kenneth R. and Annie W. Dare.

The property experienced significant code compliance issues between 2006 and 2010, when unauthorized construction of living spaces at the garage level was discovered, including a bathroom, kitchen, and additional rooms used as sleeping areas lacking proper safety features such as adequate egress, lighting, and ventilation. These violations triggered multiple Notices of Violation and an abatement process that began in January 2007 and continued through November 2009, with the final resolution occurring in April 2010 following permits for proper legalization of the ground floor spaces, including a kitchen, bedroom, bathroom, storage room, family room, and proper parking facilities. Since the resolution of these compliance issues, the building's record shows relatively few significant problems, though there have been recurring concerns about waste management, with multiple complaints between 2013-2014 regarding garbage can placement.

A sewage backup incident was reported and resolved in 2017, and there was a collapsed sidewalk issue noted and addressed in 2013. The most recent building-related service request was recorded in 2019, and there have been occasional parking-related complaints in the vicinity, including one in 2022. The property's last building permit work of note occurred in 2009, when electrical and plumbing improvements were made to support the ground floor modifications, including the installation of new lighting, switches, receptacles, a fan, and smoke detectors.
