570 4th St, San Francisco, CA 94107

The 11-unit, three-story multi-family residential building at 570 4th Street in San Francisco's South of Market neighborhood, owned by the Lorda Family Trust, was constructed in 1908 and has undergone several significant improvements and faced various challenges over the years. Most notably, the property completed mandatory soft-story retrofit work in 2016 under both residential and commercial classifications, installing HFX frames, shearwalls, and grade beams to enhance seismic safety. Recent fire safety concerns are evident, with three violations issued in 2024-2023 related to residential inspection fees, standpipe issues, and sleeping area requirements, though previous violations for sprinkler systems, electrical systems, blocked exits, and multiple fire code violations from 2020-2022 indicate ongoing fire safety maintenance challenges.

The building experienced corner damage from vehicle impact in 2006, which required repairs to framing, stucco, and entry doors, and underwent window replacements in 2014. Recent plumbing work includes a sewer repair at the rear of the building completed in 2018. Currently, there are active complaints regarding a vacant storefront (2020) and failure to comply with the Commercial Water Conservation Ordinance (2018).

The property has experienced recurring issues with its fire safety systems, evidenced by multiple fire incident responses (primarily for alarm system activations and detector malfunctions) and safety violations. More recently, in early 2025, there have been various maintenance and environmental issues reported through 311 calls, including garbage and debris concerns, an open case regarding property damage, and issues with waste receptacle management. The building has met its soft-story retrofit requirements (classified as Tier 4 with work completed and CFC issued), though its fire safety maintenance record suggests ongoing attention is needed in this critical area.
