1449-1451 Shrader St, San Francisco, CA 94117

The two-unit residential building at 1449-1451 Shrader Street, owned by Rita Robinson, is a two-story flats and duplex structure built in 1906 in the Parnassus/Ashbury Heights neighborhood. The property has undergone several significant improvements over the past few years, with a particular focus on plumbing infrastructure and window upgrades. Most recently, in 2022, the building underwent a house trap replacement, following a main water service replacement in 2020.

The property's plumbing system received substantial attention between 2013-2014, including a complete repiping, a trenchless sewer replacement, and a gas pressure test, along with the installation of a tankless water heater in 2008, indicating a commitment to modernizing essential systems. The building has also seen consistent window improvements, with records showing five separate window replacement projects between 2012-2017, all involving windows located on the back of the building and not visible from the street. These upgrades included retrofit inserts and energy-efficient replacements with U-values meeting modern standards.

Historical records from 2007 and 1982 indicate street space permits were issued, though their specific purposes are not detailed in the current records. The only recent non-building related issue documented was a defaced parking sign in December 2022, which was promptly resolved by the Department of Public Transportation. Overall, the property demonstrates regular maintenance and upgrading of critical systems, with particular attention paid to energy efficiency and plumbing infrastructure.
