37-39 Crescent Ave, San Francisco, CA 94110

The property at 37-39 Crescent Avenue in Bernal Heights is a two-unit, two-story multi-family residential building constructed in 1912 and currently owned by John and Laura Aragon. The building has undergone several significant improvements over the years, with the most recent major work occurring in 2019 when permits were filed to legalize existing construction at the garage level, including storage areas and a bathroom, along with electrical work including a weather head relocation and electrical panel upgrade, though these electrical permits expired without completion.

Prior improvements include the replacement of seven windows in 2018 with energy-efficient vinyl frames (U-factor 0.32), and a complete window replacement project in 2009 that installed 13 double-sided wood windows. The building's infrastructure has also been upgraded, with plumbing improvements in 2010 including the installation of two lav sinks, and gasline modifications in 2007 for stove and laundry facilities.

The property has experienced recurring issues with driveway blocking, particularly between May and October 2024, with at least six citations issued during this period for vehicles obstructing the driveway, though some reports resulted in "Unable to Locate" responses from officers. Other recent activity includes a garbage and debris report in early 2025 which was resolved, and a rent board housing inventory request in late 2024. The building's maintenance history shows regular upgrades to basic systems and improvements to resident comfort and energy efficiency, with the most pressing recent issues being related to parking enforcement rather than building condition or safety concerns.
