Unlock complete reportThe two-unit residential building at 4125 W Wellington Ave in Avondale, owned by CFMC Escrow Operations, has been maintained primarily through routine yard upkeep activities in recent years. Built in 1959, the property has generated a total of nine service requests in the past seven years, with seven of these being yard waste pick-up requests that were successfully closed. Most recently, there have been two yard waste requests in October 2025, and as of August 2025, there were both open and closed requests related to tree planting initiatives.
