1462 45th Ave, San Francisco, CA 94122

The two-unit, one-story multi-family residential building at 1462 45th Avenue in the Outer Sunset, owned by Ambruster David S & Kahn Ju, has experienced several significant maintenance and infrastructure issues over its history, with particular attention required to recent sewer problems. The most pressing recent concerns involve multiple sewer-related incidents in September 2024, including two sewage back-up discharges (one from a side sewer vent and another from a catch basin) and a sewer odor complaint, all of which were resolved through field work by the Public Utilities Commission.

Other recent infrastructure work includes a completed $16,000 reroofing project in 2022, and historical records show a sewer line and house trap replacement in 2010. The building's maintenance history includes several notable issues from the late 1990s, such as water leaks from a skylight, plumbing problems including mold growth, and electrical concerns with an exposed hot wire in the kitchen ceiling outlet, though all these complaints were addressed and resolved.

The property has seen various infrastructure improvements and repairs over its lifetime, with both a dry rot and termite control treatment completed in 1991 and the more recent roofing work. The building's recent history shows primary concerns centering around the sewer system, which experienced multiple failures in September 2024, suggesting potential ongoing infrastructure challenges. The property has also generated several 311 calls in recent months, primarily related to parking and sidewalk issues near the building, including multiple reports of blocked driveways and sidewalk defects, though these are external to the building itself and generally relate to neighborhood conditions rather than building-specific issues.
