Augrented Insights Report

The two-unit multi-family residential building at 131 18th Ave, owned by the Yip Family Trust, was constructed in 1924 and is classified as a Flats & Duplex structure. The property underwent significant window improvements in 2006, when all 36 windows (excluding front-facing units) were replaced with new white vinyl windows at a cost of $17,000.

A street space permit was issued in 2005, though the specific purpose and cost were not applicable. Recent activity at the property in 2023-2024 has been dominated by multiple parking enforcement issues, particularly regarding driveway blockages, with eight documented cases of blocked driveways between February and May 2024, resulting in several citations and one tow-related incident.

The pattern of parking violations suggests ongoing challenges with street parking in the area. Additionally, there was one report of tree-related issues in February 2024 involving a fallen tree. The building's documented history shows no major structural or safety concerns beyond these parking-related incidents, and the last significant building improvement (window replacement) occurred approximately 17 years ago.
