53-55 Lupine Ave, San Francisco, CA 94118

The two-unit residential building at 53-55 Lupine Avenue, owned by Paul & Eunyoung Lee, is a two-story flat/duplex constructed in 1951. The property has undergone significant modifications and improvements over recent years, most notably the successful addition of an ADU (Accessory Dwelling Unit) in 2020, conversion work valued at $26,876. In 2023-2024, crucial safety improvements were implemented, including the installation of a fire sprinkler system with 13 sprinklers in the ground floor dwelling ($14,799) and a new sprinkler monitoring system ($8,656).

More recent work includes a scheduled flat roof overlay with specified materials, costing $12,000, showing ongoing maintenance commitment. The building has experienced several compliance and safety-related issues over its history, including complaints in 2022 regarding unpermitted construction and boiler work, though these complaints are now marked as not active. A cluster of complaints in 2019-2020 concerned construction noise and possible unpermitted work, primarily during the renovation and modernization phase that included kitchen and bathroom remodels in both units.

The property's systems have been extensively upgraded, with new furnace heating units installed in 2022 to address specific complaints, along with comprehensive plumbing and electrical work throughout the building. The building's fire safety systems have been notably improved, with multiple alarm system activations recorded, all of which were either malfunction-related or unintentional with no fire incidents or civilian injuries reported. Recent municipal service calls in late 2023-2024 have primarily concerned street cleaning and maintenance issues in the vicinity of the property, rather than building-specific concerns.
