1407 Lyon St, San Francisco, CA 94115

1407 Lyon Street is a three-unit, three-story multi-family residential building located in San Francisco's Lower Pacific Heights neighborhood. Built in 1900 and currently owned by Mark and Shirley Vandewiel, this property has undergone several significant renovations over the past two decades, with the most recent work occurring in 2024. Current permitted improvements include a kitchen remodel in Unit B (approximately 60 sq ft) with associated plumbing and electrical work, and substantial interior renovations to the primary unit including window and door replacements and railing work, with permits valued at approximately $250,000.

The building's history shows considerable investment in maintenance and upgrading systems, including foundational work, termite remediation, and various unit improvements. The property has a documented history of regular safety inspections by Housing Inspection Services in 2003, 2008, and 2017, with no recent violations recorded. While there was a brief inspection in 1996 regarding an allegedly illegal unit, this was resolved quickly.

The building has experienced four fire alarm activations, though none resulted in injuries or significant incidents, and a single gas leak incident was documented. Recent 311 calls from 2020-2022 predominantly relate to parking issues, street cleaning, and a damaged tree, rather than building-specific concerns. The property's maintenance record shows consistent attention to structural and safety elements, with multiple permits focusing on foundational stability, termite issues, and the legalization of an additional unit in 1962. The recent permits for substantial interior improvements suggest ongoing commitment to modernization and upkeep of the building's systems and living spaces.
