41-49 18th Ave, San Francisco, CA 94121

The two-story, five-unit multi-family residential building at 41-49 18th Avenue, owned by Bernhardt C & Judith Rosen, has a documented history dating back to its 1920 construction. The property has undergone several significant infrastructure improvements in recent years, including a complete electrical system upgrade in November 2024 with the replacement of the Zinsco electrical panel and an earlier underground electrical conversion in 2004. The building's maintenance history shows attention to structural elements, including various repairs to stair landings and beams due to dry rot in 2006, and more substantial work in 2003 involving timber replacement and brick stack modifications.

The building faced multiple violations in 2002-2008, primarily related to fire safety and security concerns, including problems with egress obstruction, stairs, fire escape maintenance, combustible storage, and security locks. These violations were ultimately all abated by June 2009. A 1996 roofing project was recorded but expired without confirmation of completion.

More recently, there have been multiple parking enforcement issues near the property, with citations issued for vehicles blocking driveways between September 2023 and December 2024. The building had three minor fire department responses (alarm activation, service call, invalid assist) with no injuries reported. Recent maintenance indicates ongoing attention to building systems, though the frequency of parking-related complaints suggests an ongoing challenge in the vicinity.
