21 Deming St, San Francisco, CA 94114

The two-unit residential building at 21 Deming Street in Corona Heights, owned by Reda Trust, has undergone several significant improvements and maintenance work since its construction in 1955. Notable recent enhancements include the installation of a 3.46kW solar PV system in 2019, and in 2017, the installation of a walk-in tub with associated electrical work in the first-floor bathroom.

The property experienced a concerning incident in 2016 with a rockslide at the rear of the property, which required monitoring fees until its resolution, and has undergone various maintenance projects over the years, including roof maintenance in 2022, window replacements in 2008 and 2010, deck joist replacement in 2007, and multiple electrical and plumbing upgrades. The building's maintenance history shows regular upkeep, with the most recent roofing maintenance permit filed in 2022, and substantial improvements including deck area expansion (1999-2000), garage and interior wall repairs (2012), and bathroom renovations (2017).

Recent activity around the property includes various 311 calls primarily related to street cleaning, parking enforcement, and public maintenance issues such as overflowing city garbage cans and catch basin maintenance in 2023-2024. While these external issues don't directly impact the building's condition, they provide context about the neighborhood's infrastructure and services. The property has been subject to proper permitting for major work, though there was one complaint in 2004 regarding unpermitted reroofing work, which was promptly addressed the next day.
