The property at 607-609 Waller St is a three-story, multi-family residential building located in Hayes Valley, containing 4 units and owned by Phsw Investments Llc. Built in 1900, this flats/duplex-style building has undergone several significant renovations over the years, with the most recent improvements focusing on bathroom modernization in 2020 (cost: $13,500) and 2017 (cost: $14,000), including shower conversions, new vanities, and associated plumbing and electrical work.

A major structural upgrade occurred in 2004 when the ground floor unit received substantial improvements including foundation replacement, subflooring work, dryrot repair, and new insulation (cost: $50,000), along with electrical system enhancements including new wiring for lighting and receptacles (cost: $50,000). The building currently has several active violations from a 2008 inspection that remain unresolved, primarily related to fire safety and security requirements, including the need for proper fire extinguishers, handrails, deadlatch locks, and security features. These violations also include concerns about combustible storage and sanitation.

The building's mechanical systems were updated in 2012 with the installation of new furnaces on the 2nd and 3rd floors, accompanied by gas line modifications. Recent 311 calls from 2024-2025 have primarily concerned exterior maintenance issues such as graffiti, tree maintenance, and flooding, while there have been multiple reports of illegal parking in the vicinity. The only recorded fire-related incident was a false alarm due to system malfunction.
