649-651 Lake St, San Francisco, CA 94118

The two-unit residential building at 649-651 Lake Street, constructed in 1909, has experienced several maintenance and structural issues over recent years, with the most pressing concerns revolving around water drainage problems. A significant building violation was reported in October 2022 regarding improper drainage from the rear concrete patio, which was found to be sloped in such a way that it directed water toward a neighboring property's garage area. This issue led to multiple complaints and inspection activity, with the violation being abated in August 2023, though a related complaint about inadequate drainage (202306960) was still active as of April 2023.

The building has a documented history of maintenance work, including significant repairs to address water-related issues and interior damage. In 2014, approximately 1,800 square feet of sheetrock and plaster was repaired in both units, while in 2010, work was performed to address a bathtub leak that caused sheetrock and dry rot damage in unit 651. Earlier repairs from 2008 involved fixing cracked cement on the ground level, and in 2000, both roofing and kitchen/bathroom remodeling work was permitted.

The property has also undergone infrastructure improvements, including a sewer trap replacement in 2009 and changes to parking space configuration in 1997. More recent activity at the property has included multiple construction-related noise complaints in 2022, though these were properly routed to the Department of Building Inspection for tracking. The building's management has demonstrated responsiveness to maintenance needs, with repairs being performed as various issues have been identified, though the recurrence of drainage-related problems suggests this remains an ongoing concern. Additional external service requests have been mostly routine, involving tree maintenance and parking issues, with all 311 calls in the past three years marked as resolved.
