55 Hancock St, San Francisco, CA 94114

The two-unit residential building at 55 Hancock Street, located in the Eureka Valley/Dolores Heights neighborhood, is a two-story flats and duplex structure constructed in 1962 and currently owned by Calum L Mackay & Paul F She. The building has undergone several significant maintenance and improvement projects over the past three decades, with the most recent major work being the replacement of six rear siding doors in 2019 ($26,000). In 2017, the property underwent both roof work and some investigative siding work (totaling approximately $27,000).

Earlier improvements include a window replacement project in 2014 involving twelve street-visible windows and reshingle work on the second and third floors ($16,000), and another roofing project in 2008 ($5,600). Historical permits show earlier maintenance work dating back to 1991 and a deck repair permit from 2000 that expired without completion. The property has experienced several parking-related incidents in recent years, particularly in 2021, with multiple reports of driveway blockages requiring parking enforcement intervention.

There have also been two general street cleaning calls in 2021 and one regarding waste in 2020. More recent incidents in 2024 include a water leak investigation and two service requests, though these appear to relate more to street infrastructure than building-specific issues. The building's maintenance history suggests regular upkeep, with particular attention paid to exterior elements such as roofing, windows, and doors, though some historical permits have either expired or had limited information about completion status. The most significant recent building improvement, the door replacement in 2019, included energy-efficient upgrades with a specified U-factor of 0.38.
