4430-4432 20th St, San Francisco, CA 94114

The three-story multi-family residential building at 4430-4432 20th Street, situated in the Eureka Valley/Dolores Heights neighborhood, is a 1898 flats and duplex structure currently owned by Jeffrey Craig & Niede Henne. The building has undergone several significant renovations and maintenance projects over the past few decades, with notable work including a comprehensive deck reinforcement and repair project in 2001 (cost: $15,000), kitchen upgrade in 2001 ($50,000), and a first-floor powder room installation in 2010 ($7,000). A critical safety incident occurred in early 2010 involving improperly vented appliances near the rear stairwell, which resulted in violations that were abated by April 2010.

The property experienced plumbing infrastructure work in 2016 with the replacement of approximately 13 feet of sewer lateral and new sewer trap installation. Recent maintenance matters have primarily involved external issues, including multiple reports of tree root damage to the sidewalk (ongoing since 2024) and several parking-related complaints. The building has undergone various safety-related inspections, including a lead hazard warning in 2009 and associated exterior paint maintenance requirements.

Maintenance activities have included electrical and plumbing upgrades, such as the installation of a new pellet stove in 1995 and various repairs documented through building permits. The property has had some historical issues with building code compliance, as evidenced by a 2019 complaint regarding unauthorized construction/demolition work, though this complaint is listed as not active. Recent plumbing-related service requests include a sewage back-up discharge incident from the side sewer vent in December 2024.
