1243-1247 Jackson St, San Francisco, CA 94109

The three-unit multi-family residential building at 1243-1247 Jackson Street in Nob Hill, owned by the Sharon L Wong 2009 Trust, is a three-story structure constructed in 1908. The property has undergone several significant improvements over the past decade, with the most recent being a comprehensive window replacement project in 2022 that installed 20 new wood windows (15 in the front, 5 in the back) meeting latest energy efficiency standards with a U-factor not to exceed 0.30.

Between 2021-2022, substantial interior upgrades were completed across all three units, including bathroom renovations, electrical improvements with new recessed lighting, plumbing updates with new fixtures, and the installation of modern bathroom ventilation systems. A notable infrastructure upgrade occurred in 2010 when the electrical service was enhanced from 100-amp to 200-amp with new meters and sub-panels. The building has undergone regular routine inspections by Housing Inspection Services in 1999, 2001, 2009, and 2016, with all violations from the 2009 inspection being promptly addressed and abated by March 31, 2009.

These violations included safety-related issues such as water heater elevation requirements, fire extinguisher installation, and gate self-closing mechanisms, all of which were resolved within three weeks. The property experienced a sanitary sewer vent issue in March 2022, which was promptly addressed, along with recurrent sidewalk cleaning needs noted in 2019-2024, suggesting regular maintenance requirements typical for the neighborhood. The building's recent renovation history demonstrates ongoing maintenance and upgrading of the property, particularly focusing on energy efficiency and modernizing essential systems, while historical compliance issues from 2009 have been fully resolved.
