1548 15th St, San Francisco, CA 94103

This two-unit, two-story multi-family residential building located at 1548 15th Street in the Inner Mission, was constructed in 1908 and is currently owned by TRS Holdings LLC. The building has undergone several significant modifications and faced various regulatory challenges, particularly between 2007 and 2014. Notable construction work includes a substantial 2012 project costing approximately $240,823 to build out a second-floor residential unit and add ADA-compliant facilities, followed by multiple related improvements in 2013 including electrical upgrades, HVAC installation, and facade modifications.

However, the property has an active building violation from 2008 regarding unauthorized conversions of spaces and facade changes, which represents the building's most persistent regulatory issue. The structure's history shows attention to compliance matters, with earlier violations related to unpermitted attic build-up and restoration work in 2008, and a 2014 Vacant Building Ordinance violation that was later resolved. Recent activity at the property (2023-2024) has primarily involved exterior maintenance issues rather than structural or use violations, with multiple 311 calls regarding street cleaning, graffiti removal, and debris management.

The building has undergone various infrastructure improvements over the years, including plumbing upgrades, electrical service relocation (2006), and multiple street space permits, indicating ongoing maintenance and modernization efforts by ownership. While historical fire complaints from 2007-2008 were investigated, they were found to have no merit, and there are no recorded fire incidents since then. The property has maintained its residential classification throughout its history, with various permits seeking to establish and confirm legal uses.
