11 Cook St, San Francisco, CA 94118

The two-unit residential building at 11 Cook Street, currently owned by the Gilliland Revocable Trust, has undergone significant improvements since its original construction in 1958. The most substantial renovation occurred in 2008-2009, when the property underwent a comprehensive transformation including the addition of a third floor, rear extension, and complete remodeling of all three floors with an extensive electrical and plumbing upgrade. This major project included the installation of new 200-amp electrical panels for both units, re-wiring throughout, and the addition of four new bathrooms with modern fixtures and plumbing systems.

More recent improvements include a master bathroom remodel in 2019, and the replacement of the existing roof deck with bird-safe materials in 2017. The building has also undergone necessary infrastructure work, including foundation replacement and basement improvements in 2009. The property has been generally well-maintained, with proper permits obtained for substantial work, though there was one building complaint in 2006 regarding unpermitted construction that was resolved by 2008.

Recent maintenance issues have primarily involved exterior concerns such as street cleaning, parking violations, and tree root damage to the sidewalk, as documented in 311 calls from 2023. All known building systems - electrical, plumbing, and structural - have been progressively updated, with the most recent work focusing on interior improvements and maintenance of exterior features. The building's history shows regular updates to keep systems modern and compliant, with no significant safety incidents on record other than a minor false alarm transmission documented by the fire department.
