624 Carolina St, San Francisco, CA 94107

624 Carolina Street is a two-unit residential building located in Potrero Hill, owned by Victor & Deborah Dei Rossi. This two-story flats/duplex structure, built in 1907, has undergone several significant changes and faced ongoing maintenance issues over the years. The most recent major work was completed in September 2023, involving the construction of an 8-foot retaining wall at the rear of the property to maintain existing grade, for which the owners invested approximately $23,553.

The building's history includes a demolition of a single-family dwelling in 1986 prior to the current structure being approved, and street/sidewalk permits issued in 2012. More recently, the property has experienced numerous parking enforcement issues, particularly between February and May 2024, with multiple reports of vehicles parking on the sidewalk, resulting in several citations and warnings. There was also one construction-related noise complaint in April 2024, though this was deemed invalid by the Department of Building Inspection.

The building has a history of false fire alarms and system malfunctions, with nine documented incidents between 2017 and 2022, though none resulted in civilian injuries or actual fires. These incidents show a pattern of alarm system issues that have required multiple responses from the fire department, and while these events are not uncommon in older buildings, they represent a consistent maintenance challenge for the property. The property has undergone various transformations since the original structure was demolished in 1986, and while the recent retaining wall construction indicates proactive maintenance, the ongoing parking issues and historical alarm system problems suggest some areas of concern regarding resident experience and building systems reliability.
