342-352 Pierce St, San Francisco, CA 94117

The 6-unit, 3-story multi-family residential building at 342-352 Pierce Street in Hayes Valley, owned by M & K Klestoff 1990 Family Trust, has undergone significant renovations and compliance work since its 1900 construction. Most notably, the building completed its mandatory soft-story retrofit program requirements (Tier 4) with Certificate of Final Completion issued, though there were violations initially filed in late 2022 regarding uncompleted work that were abated by January 2023. The property has seen substantial improvements over the past five years, including the installation of a new fire sprinkler system ($15,600) in 2022 and the addition of an ADU in the basement area (2018, $98,800) along with mandatory seismic retrofit work.

The building's systems have been modernized with multiple heating system installations (including two systems in 2014 and one in 2011), comprehensive plumbing upgrades including rerouting for upstairs units and new underground plumbing in 2021, and electrical system improvements including multiple kitchen and bathroom remodels with updated circuits, lights, and appliances. Historical violations and complaints have typically been addressed promptly, with past issues including handrails, self-closing doors, and smoke detector installation being resolved. The building's maintenance record shows regular attention to infrastructure, with recent 311 calls primarily relating to exterior maintenance and neighborhood issues rather than building-specific problems.

The property's planning records confirm the successful addition of an ADU at the basement level, completed under proper permits and guidelines. While there was a fire-related complaint in 2019, it was resolved within a week with conditions corrected, and there have been no significant fire incidents reported since. The building's recent permit history and completed soft-story program compliance indicate active management and investment in maintaining and upgrading the property to meet current safety standards.
