Augrented Insights Report

The property at 3783 20th Street is a 20-unit, 3-story multi-family residential building constructed in 1924 and currently owned by SF 3783 20th Street LLC. The building has undergone numerous renovations and maintenance projects over the past decade, with significant work completed on Unit 10 in 2019 (kitchen and bathroom remodel, $35,000 total). Recent major maintenance activities include 2023 termite and fungus repairs to the back porch and steps ($13,400) and a 2024 boiler replacement with new Peerless units ($134,000), though there was a recent complaint in December 2023 regarding boiler permit renewal.

The building's fire safety systems have received particular attention, with a 2022 fire alarm system upgrade to meet current codes ($33,000) and multiple fire-related complaints and violations between 2023-2024, including issues with sleeping area requirements and alarm system maintenance. The building has experienced several significant maintenance and safety concerns over the years, particularly in the 2005-2006 period when there were multiple violations related to mold/mildew, interior surfaces, lead paint hazards, and water damage, all of which were ultimately abated by August 2006. There have been recurring issues with the heating system, plumbing, and electrical systems, with several complaints about heating defects and water-related problems between 2015-2019.

Recent fire safety violations in 2024 regarding alarm system maintenance and records have been referred to hearing. The property has also seen numerous unit renovations over the years, including various units receiving modernizations such as new appliances, bathroom updates, and electrical improvements. Outside of the building itself, there have been several parking-related complaints in 2023-2024, though these are not directly related to building conditions.
