4499 17th St, San Francisco, CA 94114

The property at 4499 17th Street in Corona Heights is a 2-story, 4-unit multi-family residential building with ground-floor retail space, constructed in 1900 and currently owned by Batshon Group LLC. The building has experienced several significant structural and safety issues over its history, with the most recent major work being a foundation replacement and shear wall installation in 2013 ($25,000). In 2011, the building suffered damage from a vehicle incident that compromised structural elements, requiring repairs to corner posts and header beams ($7,000).

The property has a history of unauthorized modifications, particularly concerning the retail space, with violations in 2004-2005 related to the expansion of a liquor store into residential areas without proper permits. These violations were ultimately abated, and the property later received approval for the "New Upper Terrace Market" grocery store use. Recent maintenance and safety records show some ongoing concerns, including three graffiti incidents reported in January 2025 and various street maintenance issues.

The building's safety history includes three fire-related incidents, though none resulted in civilian injuries: two false alarms (one in 700 category and one from a malfunctioning smoke detector) and one gas leak incident. The property has undergone various infrastructure improvements, including plumbing upgrades with the installation of mop and three-compartment sinks in 2015, and electrical improvements including Ufer ground installation in 2013. Recent 311 calls indicate ongoing maintenance issues in the surrounding area, though many of these were resolved with no major work required.
