449-451 11th Ave, San Francisco, CA 94118

The Schaefer Trust-owned property at 449-451 11th Avenue is a two-unit, two-story multi-family residential building constructed in 1906, currently undergoing significant proposed modifications. The most recent substantial renovation work on record occurred in 2014, involving a comprehensive bathroom remodel costing $17,500 that included new plumbing, electrical work, and insulation improvements.

The building has undergone several notable improvements over the past decades, including a $60,000 interior remodeling project in 2005 that involved wall modifications and ceiling work, and significant electrical system upgrades throughout multiple rooms in 2005, including rewiring of bedrooms, living rooms, and laundry areas. Earlier improvements include roof replacement (1998), rear stair reconstruction (1998), and window upgrades (1983). The property has experienced recurring issues with driveway blocking in recent years, with multiple parking enforcement calls between February 2023 and October 2023, suggesting ongoing challenges with parking management in the area.

Additionally, there are current exterior maintenance concerns, with recent reports of an overgrown tree blocking the sidewalk (October 2024) and a sidewalk defect (August 2024). Importantly, there is an active planning application under review proposing substantial modifications to the building, including excavation work, a rear horizontal addition, and interior renovations across both units, which would significantly alter the building's layout and living spaces. This proposed work represents the most significant planned change to the property in recent history, adding approximately 1,200 square feet of conditioned space with new bedrooms, bathrooms, and laundry facilities.
