Augrented Insights Report

The property at 4238-4240 Irving Street is a two-unit, two-story multi-family residential building constructed in 1978, currently owned by Kwong Yip Cheung & Susan Ch. The building has experienced several significant maintenance and safety issues in recent years, with the most pressing concerns including recurring pest problems, water damage, and safety violations. Notable incidents include a rodent infestation reported in August 2024, potential gas explosion risk in February 2024 involving a washing machine near water heater and gas lines, and multiple plumbing issues including sewer leaks in January 2022.

The building has a documented history of electrical and safety violations, particularly concerning common area lighting and emergency systems, with a significant complaint in January 2021 regarding unsecured entry points and turned-off stairwell lighting. Previous building improvements include window replacements in 2010 and 2015, bathroom fan replacements in 2014, and various electrical upgrades, though many of these improvements were made in response to violation notices. The property has gone through several cycles of permit compliance and violations, with recent fire safety concerns being addressed in 2020 involving exit maintenance and combustible materials.

A retaining wall and wooden fence repair was completed in 2021 following a violation notice. Multiple building complaints from 2019-2024 indicate ongoing maintenance challenges, including issues with heating systems, water damage, and electrical systems. The building's maintenance history reveals a pattern of reactive responses to violations rather than proactive maintenance, with recent complaints suggesting continuing concerns about building security, infrastructure, and basic systems functionality.
