Augrented Insights Report

The two-unit, two-story multi-family residential building at 4256 23rd Street in Noe Valley, owned by Carl W & Laura A Friedman, has undergone significant improvements since its 1907 construction. The most substantial renovation occurred between 2009-2010, when a comprehensive horizontal addition was completed at a cost of $250,000, adding approximately 1,000 square feet including a master bedroom suite, study, laundry facilities, two bedrooms, kitchen, and roof deck. This project also involved extensive updates including window relocations, new exterior stairs, and comprehensive plumbing and electrical upgrades, with the installation of new 150-amp service, three sub-panels, and complete rewiring.

Historical records show earlier improvements including multiple window replacements (2005), bathroom and kitchen renovations (1997), roofing work (1997, 2005), and a comprehensive remodeling of various interior spaces (1985). Recent maintenance and safety issues have emerged in the vicinity of the property, particularly regarding sidewalk access. Numerous citations for sidewalk parking violations were issued in late 2023 through early 2024, with at least two resulting in citations.

There are also ongoing concerns with street maintenance, as evidenced by multiple reports of garbage and debris between April 2023 and February 2024, though most of these cases have been resolved. A tree-related safety concern was reported in July 2023 regarding lifted sidewalk roots, which remains open. The most recent building maintenance records indicate no major structural or system issues since the extensive 2009-2010 renovations, and all permitted work was completed successfully. However, the concentration of recent 311 calls regarding parking and street cleaning suggests there may be ongoing challenges with neighborhood maintenance and access around the property's location.
