1924-1930 Polk St, San Francisco, CA 94109

The property at 1924-1930 Polk Street in San Francisco's Nob Hill neighborhood is a 2-unit, 2-story multi-family residential building constructed in 1904, currently owned by the Ubben 2000 Trust. The building has undergone several significant improvements over the years, with the most substantial renovation occurring between 2005-2006 when approximately $116,000 was invested in interior remodeling of the first floor and basement for music class space, including foundation repairs, new accessible restroom installation, and structural improvements with steel tubes and beams. This project also involved electrical upgrades with a new 200-amp service installation and comprehensive wiring work.

More recently, in 2013, the building received a complete reroofing with a $21,000 investment. The property has experienced an unusual cluster of maintenance issues in the surrounding area, with ten Reports of garbage and debris incidents recorded between December 2024 and January 2025, primarily involving abandoned waste and overflowing city garbage cans. There were also two instances of graffiti reported in December 2024, affecting a city receptacle and a mailbox, though these were not considered offensive.

Building safety records show two fire department responses - one for a smoke detector activation and another for a false alarm, neither resulting in any injuries. While there was a planning record related to the conversion of the upper floor dwelling unit to commercial use/office/sound studio, this case was closed with no violation found. The building's documented history suggests regular maintenance and improvements have been undertaken, particularly focused on structural and safety enhancements, though the recent spike in street cleaning issues in the vicinity may warrant attention.
