Augrented Insights Report

The 3491 19th Street property is a 23-unit, 3-story multi-family residential building constructed in 1906, currently owned by Colbert T Dare & Patty Chu. The building has undergone significant improvements in recent years, including completion of a soft-story retrofit in 2018 (as a Tier 4 building) and various commercial tenant improvements.

Most notably, there have been several concerning safety issues in 2023-2024, including two open fire violations (for sleeping area requirements as of 11/26/2023, and standpipe/missing caps as of 07/17/2024), and a recent investigation in August 2024 regarding an unpermitted walk-in cooler installation. The building has experienced recurring maintenance challenges between 2015-2024, including previous violations for heat provision, water damage, mold/mildew, and lead paint hazards, though most have been resolved.

Recent commercial improvements include the installation of a new awning (2024) and various restaurant-related modifications between 2018-2021, including electrical upgrades, plumbing work, and accessibility improvements. The property has also generated multiple 311 calls between late 2024 and early 2025 regarding garbage and debris on adjacent sidewalks, which have been generally resolved. While the building has completed major safety upgrades like the soft-story retrofit, ongoing fire safety violations and recent complaints about unpermitted modifications suggest there are still some outstanding safety and compliance issues requiring attention.
