4172 20th St, San Francisco, CA 94114

The three-unit multi-family residential building at 4172 20th Street in the Eureka Valley/Dolores Heights neighborhood is a two-story apartment structure built in 1900 and owned by David A. Batiloro.

The building underwent significant renovations in the 1990s, including a kitchen and bathroom remodel completed in 1994, and more recent work in 2007 involving replacement of rotted deck boards and handrail repairs at a cost of $4,500. Prior to this work, the building faced multiple housing violations in May 2007 related to stair repairs that required a building permit, though these violations were abated by August 2007. Two apartment house inspections were conducted in 2001 and 2002, with one complaint about major remodeling work being filed and subsequently resolved in 2001.

More recently, there have been multiple parking-related incidents near the property, particularly throughout 2023-2024, with various reports of vehicles blocking driveways and parking on sidewalks. A sidewalk defect involving a lifted sidewalk was reported to the Department of Public Works in May 2022 and remains open as of now. The building's maintenance history shows attention to both structural and safety improvements, with all identified violations having been addressed within reasonable timeframes.
