Augrented Insights Report

The 78-unit multi-family residential building at 50 Church Street, managed by 400 Duboce LLC, is a 4-story structure built in 1905 in Hayes Valley. Recent improvements include ongoing maintenance and upgrades, with the most recent projects being a kitchen and bathroom remodel in Unit 408 (2024) and an upgrade to the fire alarm system to comply with current codes (2024). The building has undergone significant unit renovations since 2020, with multiple apartments receiving kitchen and bathroom upgrades, washer/dryer installations, and associated electrical and plumbing work.

Notable infrastructure improvements include the replacement of the steam boiler in 2023 and comprehensive fire alarm system upgrades in 2024. The building has faced several concerning issues in recent years, particularly in 2024, including recurring rodent infestations, heat outages, and electrical system concerns. Complaints in early 2024 reported complete building-wide heating failures and ongoing pest problems, while electrical complaints revealed concerns about unauthorized solar panel installations and associated system problems.

A significant concern emerged in late 2024 regarding potential hazardous materials exposure related to 2022 construction work, though this complaint remains active. Fire safety has been a recurring issue, with multiple violations noted between 2023-2024 regarding alarm system maintenance and requirements, including an open violation as of November 2023. The building is classified as "soft story" Tier 2, indicating completed seismic retrofit work. Historical violations from 2009 included various building maintenance issues that were subsequently resolved.
