Augrented Insights Report

The two-story multi-family residential building at 335 Ralston Street in Merced Heights, owned by Si Zhi Qing, was constructed in 1928 and has undergone several significant modifications over the years. Most notably, in 2014, a substantial renovation project costing $152,000 was completed to legalize additional living spaces, including bathrooms, bedrooms, family room, and kitchen on the first floor, along with a bedroom and storage room at the lower level.

This work was followed by multiple deck repairs in 2017 and 2019, and a garage door replacement in 2020. The property has experienced some compliance issues, with a recent 2024 violation regarding incomplete front setback landscaping and permeability work, which was subsequently addressed in August 2024. The building's history includes two documented fire incidents, though neither resulted in civilian injuries, with causes related to equipment failure and cooking.

While there were also two fire complaints (one regarding weeds/grass in 2021 and a blocked exit complaint in 2006), these issues were either deemed duplicate or without merit. The property has undergone various maintenance and improvement works over the years, including plumbing and electrical updates, with the most recent permit in 2024 involving landscape alterations. Recent 311 calls primarily relate to street-level issues such as parking violations and debris removal, rather than building-specific problems, suggesting regular external maintenance of the property.
