Augrented Insights Report

840-842 Valencia Street is a three-story multi-family residential building with 5 units, constructed in 1924 and currently owned by Rex C H Cheung and May Chan R. The property has undergone several significant improvements, most notably a major restaurant renovation in 2017 costing $220,000 that included kitchen remodeling, washroom relocation, bar addition, lighting installation, and electrical upgrades. This followed substantial restaurant infrastructure work in 2004-2005, including the installation of fire sprinklers, new HVAC systems, and concrete slab repairs, all suggesting a well-maintained commercial component.

The building has experienced various maintenance issues over the years, with the most recent complaints from late 2024 regarding peeling paint, weatherproofing concerns, and lead paint notifications. These violations, though significant, were typically addressed relatively promptly, with previous issues including roof leaks (2008), pest problems (2009), and multiple painting violations being resolved through normal channels. Recent activity at the property includes several 311 calls in late 2024 regarding illegal parking and street cleaning issues, as well as some shared spaces complaints documented by the fire department in 2022.

The building's commercial space has maintained its restaurant status through proper channels, with approvals confirming its "Bona Fide Eating Place" designation requiring 51% food sales. The property's maintenance history shows a pattern of periodic upkeep and compliance with fire safety requirements, though some recent inspections have noted multiple interior surface issues that were subsequently addressed. The extensive permit history indicates regular investment in building maintenance and improvements, particularly focused on the ground floor commercial space, while the upper residential units have experienced fewer documented issues.
