The 21-unit apartment building at 490-498 Hayes Street, owned by Giampaolo Boschetti and constructed in 1914, is a three-story multi-family residential building that has undergone significant improvements over the past decade. Most notably, the building completed mandatory soft-story retrofitting in 2017, with both residential ($122,000) and commercial ($88,000) components, demonstrating compliance with seismic safety requirements. The property has maintained active commercial spaces throughout its history, with recent changes including a successful transition from a cafe to a full-service restaurant in 2019-2020, involving significant tenant improvements ($50,000) and plumbing upgrades. The building has experienced several maintenance and upgrade projects, including HVAC system installations (2013), electrical system improvements, and multiple plumbing upgrades. However, there have been some concerning safety issues, particularly a recent active complaint from December 2023 regarding common areas, as well as multiple fire code violations noted between 2018-2022, including issues with alarm systems, exits, and storage pathways. The building had a notable incident in early 2013 involving unauthorized installation of telecommunication equipment and antennas, which resulted in multiple citations but was ultimately abated by February 2013. Recent plumbing work completed in 2024 involved the installation of floor sinks and hand wash sinks, indicating ongoing maintenance and upgrading of building systems. The property has maintained compliance with various building codes, successfully completing a range of required improvements including electrical upgrades, structural reinforcements, and plumbing modifications, although there are some outstanding concerns regarding common area maintenance as of late 2023.
