4301-4303 20th St, San Francisco, CA 94114

This two-unit residential building, located at 4301-4303 20th Street in the Eureka Valley/Dolores Heights neighborhood, is a two-story flats and duplex structure built in 1931 and currently owned by Christopher John Komater 20. The property has undergone several significant improvements in recent years, most notably in 2017 when it received substantial electrical upgrades including a 200-amp bus upgrade, installation of a new 30-amp/240V line for an air conditioning unit, and the addition of a solar PV system comprising 12 LG 315W modules. That same year, a mini split air conditioner was also installed.

In 2021, the building received a complete reroofing, representing a $24,000 investment in building maintenance. The property has recently experienced some maintenance and enforcement issues, particularly in 2024, with multiple 311 calls reported throughout the year. These include concerns about sidewalk parking (with several incidents reported and unable to be validated by responding officers), illegal postings, construction noise complaints, and one open issue regarding tree roots damaging property and lifting the sidewalk.

While there have been some reports of graffiti and garbage/debris issues, most of these cases were either resolved or transferred to appropriate departments. A fire incident requiring assistance for an invalid situation was recorded, but no civilian injuries were reported. The building's permit history shows regular maintenance and upgrading of systems, with no major violations or concerning patterns in the available data.
