There was one documented fire system malfunction (a 730 System malfunction) with no civilian injuries reported, and minimal street-related issues including a sidewalk parking complaint in 2019 (which was unable to be verified) and a temporary moving sign request in 2017 that was not issued due to driveway location constraints. The property has maintained compliance with various municipal requirements, and shows a pattern of proactive maintenance and upgrading, particularly in terms of energy efficiency through solar installation and window replacements. The most recent permits and improvements indicate ongoing investment in maintaining and upgrading the property.
