1239 17th St, San Francisco, CA 94107

The 1239 17th Street property in Potrero Hill is a three-story multi-family residential building constructed in 1922, containing three units and owned by Horlino Tabios Revocable Living Trust. The building has undergone numerous renovation attempts and modifications over the years, with several significant projects being proposed or initiated but ultimately withdrawn or cancelled, including multiple attempts to add additional units between 2013-2015 and a soft-story retrofit in 2021.

Completed improvements from recent years include wood siding replacement (2020), reroofing (2020), and the installation of a tankless water heater. The building has experienced recurring issues with its plumbing and fire safety systems, including a plumbing complaint in 2020 regarding an unpermitted water heater installation, and multiple fire safety violations related to sprinkler systems and combustible materials between 2014-2022, though these were generally corrected or marked as having no merit. The property has a notable history of unauthorized unit concerns, with active planning records discussing the legalization of a third unit and the creation of an ADU in 2021.

Historical records show a potential illegal backyard unit complaint from 1998, and there was a significant roof leak issue documented in 1998 that reportedly remained unresolved until 2010. The building's systems have required extensive electrical and plumbing work, with numerous permits issued for comprehensive electrical installations and plumbing renovations completed in 2009-2010, including updates to all floors' electrical systems and the installation of new heating equipment. Recent 311 calls from late 2024 indicate ongoing exterior maintenance issues, particularly with debris and graffiti around the property.
