851 Guerrero St, San Francisco, CA 94110

The 14-unit, 3-story apartment building at 851 Guerrero Street, owned by Jack M. Lapidos, has undergone significant maintenance and repair work since its construction in 1925. Most recently, in 2024, repairs have included patching sheetrock ceilings and walls on the ground floor following plumbing and electrical work, as well as addressing kitchen and bathroom plumbing issues in Unit 4 that generated a Notice of Violation in 2021-2022.

The building successfully completed its mandatory soft-story retrofit in 2017-2019, demonstrating compliance with seismic safety requirements. Significant plumbing upgrades include the replacement of clay sewer pipes with cast iron in 2023, relocation of rain down spots, and various heating system improvements including boiler replacements in 2022-2023. The property has faced several maintenance challenges, particularly in 2022-2023, including water damage, electrical issues, and building code violations. Active violations remain regarding interior surfaces, weatherproofing, egress obstruction, and lead-based paint concerns, with a final warning letter issued in November 2024.

Building complaints from 2020-2022 documented various tenant concerns, including heating system failures, unauthorized renovation work, and garage maintenance issues. Historical records show past fire safety violations related to exit obstructions, fire alarms, and combustible storage, though these were corrected by 2007. Recent improvements include a 2022 electrical upgrade from 70amp to 400amp with 5 meters, and roofing work completed in 2022. The property has maintained regular fire safety inspections, with corrections made to fire extinguisher and alarm system issues as needed.
