1527-1529 9th Ave, San Francisco, CA 94122

The two-unit residential building at 1527-1529 9th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1948, currently owned by Norman S Nayfach & Mar since 1997. The property has undergone several significant maintenance and infrastructure improvements over the years, with the most recent work being a furnace replacement completed in February 2024.

Major structural improvements were made in 2015, including foundation reinforcement with anchor bolts, installation of plywood on basement walls, and support post stabilization at a cost of $15,000, which significantly enhanced the building's structural integrity. The building has received regular roofing maintenance, with reroofing projects completed in 2014 (at $7,280) and previously in 1991, demonstrating ongoing maintenance of the building's critical systems.

Historical records from 1989 show termite damage repair, indicating previous pest issues, though there have been no documented pest-related problems in recent years. The property underwent a significant utility upgrade in 2005 with the conversion from overhead to underground power service, including the installation of two meter services with breaker panels.
