262-264 17th Ave, San Francisco, CA 94118

Located in San Francisco's Central Richmond neighborhood, this two-unit multi-family residential building at 262-264 17th Avenue is a two-story flats and duplex structure built in 1916, currently owned by the Peter F Thornton Jr Revocable Trust. The property has undergone several significant improvements over the past decade, with the most recent notable upgrade being the replacement of two existing forced air furnaces in April 2020, indicating attention to HVAC system maintenance.

In 2017, substantial infrastructure work was completed, including a trenchless sewer installation from the house trap in front of the garage, demonstrating investment in essential systems. The building underwent comprehensive kitchen renovations in both 2015 and 2016, including electrical upgrades such as new recessed lighting, bathroom fans, garage lighting, and outlet improvements, as well as the installation of a 150 amp service with three meters and 60-amp panels. Earlier maintenance records show proactive upkeep, including foundation underpinning and electrical improvements in 2016, and repairs to address dry rot on the building's front in 2012.

The property has had multiple street space permits issued between 2016-2017, likely related to construction activities. Recent 311 calls in early 2023 and 2025 indicate occasional parking enforcement issues in the vicinity, with citations issued for driveway blocking incidents, though these are external to the building's condition and operations. The building's permit history suggests regular maintenance and upgrading of systems, with no recorded safety violations or major structural concerns in recent years.
