55-57 Norton St, San Francisco, CA 94112

The two-unit residential building at 55-57 Norton Street in Mission Terrace, owned by Lisa Wong, is a 1908 flats and duplex structure spanning two stories. The property has undergone significant recent improvements, including the installation of a solar PV system with batteries in March 2022 (8.28 kW), complete electrification with heat pump water heaters and a split ducted heat pump system in January 2023, and reroofing in April 2022 costing $10,719.

Maintenance history shows attention to structural integrity, with stair replacements completed in 2011-2012, siding and window repairs in 2010, and historical termite/dryrot remediation documented in 1994. The building experienced several maintenance challenges between 2010 and 2015, most notably in 2012 when multiple violations were recorded, including plumbing leaks, lead paint concerns, and various interior repairs required. These violations were officially abated by January 2013.

A significant complaint in July 2015 detailed multiple issues including appliance problems, plumbing fixtures, and pest concerns, though these were marked as resolved within a month. The property documented building permit applications for various repairs and improvements, including gas line work in 2010 and 2011, electrical service upgrades in 2009, and most recently, a tenant buyout at 55 Norton Street in May 2022 for $2,300. Recent 311 calls primarily relate to sidewalk parking issues and tree maintenance requests, with the most recent being a tree blockage reported in January 2024.
