650-652 Hayes St, San Francisco, CA 94102

The property at 650-652 Hayes Street is a two-unit, two-story multi-family residential building located in Hayes Valley, constructed in 1900 and currently owned by Amanda Clarke 2001 Revocable Trust. The building has undergone significant renovations and improvements over the past several years, most notably the installation of a comprehensive fire sprinkler system in 2021 ($3,800), the upgrade of electrical systems including meter relocation and wiring updates in 2018 ($12,000), and exterior maintenance work including wood siding replacement in 2019 ($7,500).

The property experienced several permit-related issues in 2004, including unauthorized demolition of rear deck and stairs, installation of unpermitted footings, and conversion of residential space to commercial use without proper approvals, though these violations were eventually abated by December 2004. Recent maintenance and improvement work has focused on safety systems, including the installation of a dedicated sprinkler monitoring system in 2021 and various plumbing upgrades. The building underwent substantial interior improvements between 2018-2021, including the installation of new HVAC systems, water and sewer lines, and electrical upgrades.

Two complaints were filed in 2020 regarding construction noise and sidewalk access, and several 311 calls were recorded in 2024 related to garbage, debris, and graffiti issues near the property. The building has had two fire alarm activations recorded, both of which were determined to be system malfunctions rather than actual fires. Recent permits and inspections, including a final inspection request in August 2023, indicate that most major work has been properly completed and inspected.
