12 Imperial Aly, San Francisco, CA 94123

The two-unit residential building at 12 Imperial Alley in Cow Hollow is a two-story flats and duplex structure built in 1906, currently owned by William L. and Lynne Spear.

The building has undergone several significant maintenance and improvement projects over the years, including a reroofing project in 2019 costing $18,560, and substantial work on the rear steps and railing system in 2012 involving replacement of rotten components and upgrading safety features for $8,000. Earlier improvements included the installation of vinyl siding on the building's rear in 2000 and seismic and foundation repairs with additional improvements in 1991, though the latter two permits are noted as expired. The property has experienced multiple sanitation-related issues over recent years, with nine documented instances between 2012 and 2015 regarding improper management of waste containers, specifically toters being left out continuously.

These reports were primarily handled by the Department of Public Works (DPW), with several cases being marked as "Privately maintained street - DPW cannot enforce," particularly in 2012. Of particular note, there was one gas leak incident reported (though the date is not specified in the records) which resulted in no civilian injuries. The building's maintenance record shows regular upkeep of critical systems, though the frequency of waste management issues suggests ongoing challenges with refuse container handling in the vicinity.
