3720 Balboa St, San Francisco, CA 94121

The two-unit residential building at 3720 Balboa Street in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1957, currently owned by Paul A. Lux and Miyoko. The property has undergone several significant improvements over the years, with the most recent substantial work being a comprehensive bathroom remodel in 2018 costing $18,000, which included plumbing and electrical upgrades such as new fixtures, a shower valve change, and the installation of additional outlets and lighting.

Prior improvements include a sewer replacement completed in 2015 and an earlier attempt in 2001 to replace all windows and install rear siding with insulation, though that permit ultimately expired. The building has experienced several minor fire-related incidents, including two false alarm activations of the smoke detector and one water or steam leak incident, though none resulted in civilian injuries or property damage. The property has faced some external maintenance challenges in the surrounding area, particularly in 2017-2020, with multiple reports of street cleaning issues related to human or animal waste, as well as incidents of graffiti and illegal postings on or near the property.

Notably, there were two attempted variance applications regarding off-street parking space removal, though both were disapproved. The building's maintenance record shows regular upkeep and improvements, with no major safety violations or building code issues currently on record. The most recent permits and completed work demonstrate ongoing maintenance and upgrading of the property's facilities, particularly focusing on interior improvements and infrastructure updates.
