The property has seen various planning applications over the years, including attempted changes for outdoor dining and a roof deck addition, though some were withdrawn or canceled. Recent building improvements have focused on safety and modernization, with permits showing work completed or in progress as recently as 2018. The property maintains compliance with safety regulations, as evidenced by the complete fire sprinkler system installation and regular building maintenance activities. The majority of the building's significant work has been focused on maintaining and upgrading both residential and retail components, with particular attention to fire safety systems and electrical infrastructure improvements.
