666-668 6th Ave, San Francisco, CA 94118

The two-unit, two-story multi-family residential building at 666-668 6th Ave in San Francisco's Inner Richmond neighborhood was built in 1908 and is currently owned by the Lee 2001 Trust. The property has undergone several significant improvements over the past few decades, most notably a reroofing project completed in 2005 costing $17,700, and the installation of 15 vinyl windows in 2002 ($6,836).

Earlier renovations include kitchen and bathroom remodeling in 1985, and a porch remodeling project that same year. Multiple permit applications from the 1990s related to structural changes and bathroom remodeling were either disapproved or expired, including a proposed horizontal addition in 1990 which was not approved.

The building has experienced recurring issues with driveway blocking, with ten incidents reported to parking enforcement between 2018 and 2023, resulting in six citations being issued, three cases where officers were unable to locate the offending vehicles, and one incident where the issue could not be validated. These parking enforcement calls suggest persistent challenges with access to the property's driveway, though they occurred in relation to street parking rather than directly within the property's own parking area. The only other incident on record was a general cleaning request for loose garbage in December 2014 which was promptly addressed by Recology.
