246-248 Carl St, San Francisco, CA 94117

The property at 246-248 Carl Street is a two-unit, two-story multi-family residential building constructed in 1916, currently owned by 246 Carl Street Eat LLC. The building has undergone significant renovations and faced several challenges in recent years. Most notably, there was a controversial penthouse addition that led to multiple complaints and violations, including issues with neighboring properties claiming damage due to excavation work in 2020. This led to the eventual removal of the unauthorized penthouse structure in late 2022, along with the installation of a skylight and conversion of a bathroom to a sauna, a project costing $50,000.

The property has seen substantial safety improvements, including the installation of a comprehensive fire sprinkler system throughout the building in 2017-2018, with a monitoring system added in 2020. Electrical and plumbing upgrades have been extensive, including a 400-amp service upgrade, rewiring, and various system installations between 2017 and 2023. The building has also undergone significant interior improvements, including the addition of a sauna and various modernizations. Multiple complaints were filed during construction periods, particularly in 2020, regarding safety concerns such as workers not wearing masks, problems with water service installation, and excavation work affecting neighboring properties.

These issues appear to have been resolved, as indicated by their "Not Active" status. The property has maintained regular inspections and compliance with fire safety codes, though a sprinkler system violation was issued in August 2022 and subsequently abated in December 2022. Recent activities (2023-2024) have primarily involved routine maintenance and service calls, including lighting retrofits and parking enforcement issues. The building's current status suggests active management with ongoing improvements and maintenance, though historical challenges related to unauthorized modifications and construction impacts on neighbors are notable events in its recent history.
