526-528 46th Ave, San Francisco, CA 94121

The two-unit residential building at 526-528 46th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1948, currently owned by the Yoneko Higashigawa Revocable Trust. The property has undergone several significant improvements over the past few decades, with the most substantial renovations occurring in 2018 when the front facade underwent complete stucco replacement, including the installation of new aluminum sliding doors and windows, with a total renovation cost of $22,000.

This project included additional work to address dry rot issues in the front facade ($5,000) and to install code-compliant metal railings on two curved front balconies ($3,000). In 2010, the building received updates including the replacement of eight windows and two patio doors ($10,000) and the installation of vinyl siding on the back wall ($3,500). More recently, in 2021, the building has been equipped with modern solar technology, with two separate permits issued for the installation of 2.56 kW solar PV systems consisting of eight modules each.

The property's maintenance history shows consistent attention to structural integrity and safety, including earlier address of dry rot issues in 1990, though there was an expired roofing permit from 1993 that suggests this work may have been completed prior to the record expiration. One minor infrastructure issue was documented in 2010 regarding a damaged curb or ramp, which was subsequently resolved in 2013. The building's permit history indicates regular maintenance and upgrading of building systems, with particular attention paid to ensuring code compliance and modernizing the property's features.
