401 Parker Ave, San Francisco, CA 94118

The property at 401 Parker Avenue is a two-story, three-unit multi-family residential building located in the Lone Mountain neighborhood, owned by Shea Tad and Chien Audrey, and constructed in 1957. The building has undergone several significant modifications and improvements over the years, most notably a major renovation project in 2018 that included attempts for horizontal and vertical extensions, though some components faced permit challenges. This project also involved the legalization of an unauthorized basement dwelling unit, with additional renovation work continuing into 2024 as indicated by the currently issued permit for sheet rock replacement throughout all apartments.

The property has experienced recurring sewer issues as evidenced by multiple 311 calls between late 2019 and early 2020, including flooding and sewage backup incidents that required PUC Sewer Operations intervention. A notable incident occurred in 2012 when the garage door required repair following an automobile accident. The building's maintenance history shows attention to basic upkeep, including window installation in 1988 and reroofing work in 2002.

The building's regulatory history includes routine housing inspections in 2000, 2005, and 2011, all of which were successfully abated. In terms of tenant history, there is record of a buyout in October 2017 involving one tenant, though no detailed information about this transaction is available. Recent infrastructure and public space issues in the vicinity have been documented through 311 calls, including parking sign maintenance and encampment reports, indicating ongoing urban challenges in the immediate area. The property's development history shows substantial investment in improvements, with permits totaling over $1.2 million in construction work, though some of this appears to have been partially modified or redefined through subsequent permit adjustments.
