Augrented Insights Report

The 15-unit residential building at 801-805 Hayes Street, owned by Acorn Ventures Limited Liability Company, is a historic 1906 structure located in the Alamo Square neighborhood. The building has recently experienced significant fire-related incidents, with records showing multiple units undergoing fire damage remediation and repairs in 2023-2024, including Units B, C, D, E, and F. The property is currently non-compliant with the Mandatory Soft Story Retrofit Program (Tier IV), with an active violation from December 2022 regarding unfinished retrofit work, which is scheduled for a director's hearing in March 2024. The building has also faced several building condition issues in recent years, including problems with weatherproofing, siding detachment, and multiple fire safety violations related to alarm systems, extinguishers, and exit blockage between 2022-2024, though most of these have been corrected.

Three additional dwelling units (ADUs) were successfully added to the property in 2022, along with recent plumbing and electrical upgrades. Historical issues from 2007-2010 included maintenance violations related to stairs, handrails, and general dilapidation, all of which were eventually resolved. The building has a documented history of fire alarm system malfunctions, with multiple instances of false alarms and system problems between 2020-2024. There was a verified building fire incident recorded, though fortunately with no civilian injuries reported.

Recent repair work has included siding replacement and various unit renovations, with ongoing rehabilitation of fire-damaged units as of 2024. The property has undergone various improvements including the installation of a full fire sprinkler system and updates to individual unit kitchens and bathrooms. Multiple complaints regarding noise during renovations in 2022 and pest issues related to a vacant commercial space in 2019 were recorded. The building's maintenance history shows regular permits for unit upgrades, though current work related to fire damage repairs and soft story compliance remains a significant focus.
