1201-1219 Mariposa St, San Francisco, CA 94107

The property at 1201-1219 Mariposa Street is a two-story multi-family residential building located in Potrero Hill, currently owned by the Vellve Revocable Trust. Built in 1907, this flat and store structure contains two dwelling units and has undergone several significant improvements over its lifetime.

The building's roofing systems have received consistent attention, with records showing completed reroofing projects in 1990 ($10,000), 2012 ($10,000), and most recently in 2020 ($16,480). An approved permit from 2003 documented plans for installing a rooftop deck over the garage and necessary stair repairs, though this permit ultimately expired.

Recent municipal service records from 2022 through 2025 show a variety of community-related incidents in the property's vicinity, including multiple parking enforcement requests, street cleaning issues, and a fallen tree emergency in March 2023 that was resolved. There was also a Rent Board follow-up request in April 2022, though this case was closed due to inability to reach the caller. The property has undergone some planning processes aimed at expansion, with approved variance applications to add a dwelling unit and a roof deck, as well as remodeling work on the existing second-floor structure, showing the owner's interest in enhancing the building's capacity and amenities.
