2255 Mariposa St, San Francisco, CA 94110

The property at 2255 Mariposa Street is a two-story, multi-family residential building located in Potrero Hill, currently owned by Gert Lanckriet and featuring two dwelling units. Originally built in 1911, the building has undergone several significant modifications over the years, with the most recent major renovation completed in 2017, which included kitchen remodeling, bathroom addition on the first floor, deck replacement, and installation of new windows and sliding doors.

This renovation was accompanied by updates to the plumbing system, including a new bathroom installation, kitchen remodeling work, and replacement of heating systems, all of which were properly permitted and completed. Earlier maintenance work includes two separate roofing projects completed in 2011 and 2016, and a routine safety inspection in 2015, which was noted as not active. The building has a complex history regarding its dwelling unit classification, with historical records showing attempts to convert it to seven units in 1986-1987, though these permits were either cancelled or expired.

The most substantial recent renovation work was carried out between 2016-2017 and was properly documented with building, plumbing, and electrical permits, totaling approximately $102,500 in improvements. Recent activity around the property, particularly in 2024, shows numerous reports of street cleaning and debris issues, including multiple cases of abandoned furniture and waste requiring city intervention, though these external matters do not directly reflect on the building's condition or management. A March 2024 street defects report mentioned a dump truck parked at the site of a completed project, which was resolved through communication with project personnel.
