3827 18th St, San Francisco, CA 94114

The two-unit residential building at 3827 18th Street in the Eureka Valley/Dolores Heights neighborhood is a single-story multi-family dwelling built in 1900, currently owned by Kay E. Koehneke.

The property has undergone several significant structural improvements over the decades, including a chimney reconstruction project in 1990 and entry step repairs due to dry rot in 1986. Most notably, in 2012, the building received an electrical system upgrade with the installation of a new 100-amp service and main panel, including grounding and bonding work, which represents the most recent major infrastructure improvement on record. The building's recent history (2023-2025) has been marked by numerous municipal services interactions, primarily related to street maintenance and public space issues rather than direct building concerns.

The area has experienced recurring challenges with sidewalk cleanliness, with multiple reports of garbage, debris, and waste between 2023 and early 2025. There have also been several instances of graffiti (both on public infrastructure and nearby property), parking enforcement calls, and one encampment report, though all these cases were closed and resolved by appropriate agencies. While these external neighborhood issues do not directly reflect on the building's condition, they provide context about the surrounding area's maintenance challenges.
