1904-1906 20th St, San Francisco, CA 94107

The property at 1904-1906 20th Street in Potrero Hill is a three-story, two-unit multi-family residential building constructed in 1988, currently owned by the Nicolas Cserepy 2019 Trust. The building has undergone several significant renovations and improvements over the past decade, with the most recent major work occurring in 2018, including a kitchen and two bathroom remodels valued at $50,000. Earlier improvements included the construction of a media room, laundry facilities, and half bath in the basement in 2016, followed by bathroom and kitchen renovations in 2018.

A comprehensive fire safety upgrade was completed in 2012 with the installation of a new fire sprinkler system throughout the building, costing $41,400, though the associated plumbing permit has since expired. The building's history shows attention to safety and modern amenities, with multiple revisions and updates to comply with building codes, including guardrail modifications, balcony surface changes, and various bathroom and kitchen improvements. There have been two documented fire incidents, both of which resulted in no civilian injuries: one false alarm and one electrical wiring/equipment issue.

More recently, from late 2024, there have been several infrastructure and maintenance issues reported in the vicinity, including flooding, graffiti, garbage concerns, and tree maintenance needs, though these primarily affect the street and sidewalk areas rather than the building itself. The property has undergone several permit revisions over the years, with most recent work focusing on interior modernization and compliance with current building standards, including the removal of unauthorized modifications noted in a 2011 complaint regarding unauthorized gutting work. The building's maintenance record shows regular updates to keep systems current, particularly in terms of water, electrical, and fire safety systems, with all recent permit work having been properly completed and signed off by city authorities.
