3930-3932 23rd St, San Francisco, CA 94114

The 3930-3932 23rd Street property is a two-story, three-unit multi-family residential building constructed in 1926 in Noe Valley, currently owned by the Marshall Family Trust 2003. The building has undergone several significant renovations and improvements in recent years, including window replacements in 2022, reroofing work in 2020, and multiple plumbing upgrades including a house trap/sewer replacement in 2018. Notable improvements include the installation of a fire sprinkler system in 2015-2016, electrical system upgrades with a new 100-amp service in 2016, and comprehensive remodeling of various units between 2013-2019, including kitchen and bathroom renovations, hallway updates, and front stucco replacement.

The property has experienced some regulatory scrutiny, most notably in 2019 when a complaint was filed regarding an allegedly unauthorized dwelling unit in the basement, resulting in multiple housing code violations related to change of use, egress, fire protection, electrical, plumbing, and mechanical systems. This issue was officially abated in November 2019. The building's infrastructure maintenance has shown attention to fire safety and modernization needs, including a new water meter for the fire sprinkler system and various plumbing and electrical improvements.

Recent maintenance issues have included multiple sewer backup incidents in September 2020, though these were resolved through city work orders. The property has had several historical building complaints regarding unauthorized work and modifications, though most of these issues appear to have been addressed, with the exception of some open pavement defect reports from 2024. Recent exterior maintenance includes window upgrades and various systems improvements, suggesting ongoing investment in the building's infrastructure and safety systems.
