127 Beaver St, San Francisco, CA 94114

The two-unit residential building at 127 Beaver Street in Corona Heights, owned by the Gay Family Living Trust, is a two-story flats and duplex structure dating back to 1900.

The property's documented improvements over the past several decades reflect a pattern of maintenance and modernization, beginning with a reroofing project in 1995, though this permit has since expired. In 2009, the building underwent a significant sustainable energy upgrade with the installation of a residential solar system consisting of 10 roof-mounted PV modules, each rated at 230 watts, along with an interactive inverter system rated at 2.3kW - a forward-looking improvement that demonstrates the property's commitment to renewable energy.

More recently, in 2013, the electrical system was upgraded with the relocation of the main service to the side of the residence and grounding improvements, which was successfully completed. The building's incident history shows minimal issues, with only one recorded complaint in October 2008 regarding damaged property, which was processed through the 311 system and subsequently closed after being transferred to the appropriate agency.
