1349-1351 Hampshire St, San Francisco, CA 94110

The two-unit residential building at 1349-1351 Hampshire Street in the Mission District, built in 1906 and currently owned by Karen Hannie Lee Chan, has experienced significant and recurring maintenance and habitability issues over the years. Most notably, between 2011-2015, the property faced multiple serious violations related to unauthorized dwelling units, unpermitted construction, and severe habitability problems including mold, insect infestations, plumbing failures, and safety hazards.

In March-April 2015, there were particularly concerning incidents involving sewage leaks affecting neighboring properties, which were among the last major complaints before the building entered a period with fewer recorded violations. The property has undergone several repair projects, including stair repairs in 2011-2012 and plumbing work in 2015 to address compliance issues, suggesting at least partial remediation of the documented problems.

Historical records show earlier maintenance work, including exterior repairs in 2002 and various renovations in the 1990s. Recent activity on the property, including multiple parking enforcement calls and cleaning requests in 2021-2024, indicates ongoing external maintenance needs are being addressed, though specific improvement to the building's internal conditions is less clear from the data available. Two fire safety violations from December 2005 regarding combustible materials were also recorded but have since been closed.
