Augrented Insights Report

The two-story, four-unit multi-family residential building at 548-550 Central Ave, owned by Xie Chang, has a documented history stretching back to 1997, with the property being built in 1900. The building has undergone several major maintenance and compliance projects over the decades, with the most recent significant work being a $13,000 reroofing project completed in 2021. A notable series of building violations was recorded in 2003, involving issues with stairs, smoke detectors, fire escape maintenance, and egress obstruction, though these were all abated by June 2003.

The building experienced water-related issues in 2006-2007 with complaints about roof leaks and mold, as well as problems with multiple violations in bathroom and weatherproofing repairs documented in 2006. Several compliance efforts are evident in the historical records, including a 2008 sewer repair, and earlier work in 1985 and 1991 to bring the building into code. There have been recurring issues with unauthorized modifications and maintenance concerns, including complaints about work without permits in 2008 and 2021, as well as a historical complaint from 1994 regarding unauthorized unit conversions.

More recently, the property has experienced multiple parking and maintenance issues, with regular reports of cars blocking driveways and some concerns about tree-related property damage in 2022-2023. The building's maintenance history suggests a pattern of addressing both routine upkeep and compliance-related issues, with most violations being resolved through subsequent repairs or improvements. While there have been periodic complaints regarding various system failures and unauthorized modifications, recent records show fewer major building code violations compared to the earlier years of documentation. The property has undergone regular maintenance processes, including the most recent roofing work in 2021, which suggests ongoing attention to building upkeep by the current ownership, though there have been some concerns about permit compliance in recent years.
