Augrented Insights Report

536 Thornton Avenue is a two-story, 10-unit multi-family residential building constructed in 1964, currently owned by Topango Group Revoc Tr. The property has undergone several significant improvements over the years, with the most recent being a comprehensive remodel of Unit #10 in 2022 costing $25,000, which included updates to the bathroom, kitchen, flooring, and other interior features.

The building completed mandatory safety upgrades including a soft-story retrofit in 2018 ($80,000) and garage fire-rated ceiling repairs in 2017 to address safety violations. Historical maintenance records show attention to fire safety systems, including the addition of a sprinkler head to the trash room (2007) and various fire system inspections with no merit findings in 2018-2022. The property has experienced periodic maintenance issues, particularly in 2017 when multiple violations were recorded regarding fire safety, mold, wall damage, and combustible storage, though all were subsequently abated.

A building fire incident with one civilian injury was recorded, though the date and specific details are not provided in the records. Recent concerns have primarily centered around parking violations and sidewalk maintenance, with multiple reports of sidewalk parking and some garbage debris issues in early 2025. The building's structural integrity appears to have been prioritized, with completed repairs for dry rot and other maintenance needs in previous years, including a reroofing project completed in 2018.
