2425-2427 Folsom St, San Francisco, CA 94110

The property at 2425-2427 Folsom Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, owned by Lawrence S and Anny F. Built in 1900, this flats & duplex building has undergone several significant modifications over the years.

Most notably, in 2015, there was an attempted renovation project worth $36,000 to address multiple improvements including the removal of an illegal kitchen, conversion to laundry facilities, and bathroom modifications on the ground floor, though this permit was ultimately revoked. A plumbing permit for a laundry room and half bathroom installation was issued in early 2015, and electrical upgrades were completed in 2009 (basement and first floor) and 2005 (200-amp underground conversion). The building has experienced certain compliance issues, including a violation in 2010 related to unauthorized roofing work that was subsequently abated in 2011.

The property's maintenance history shows several 311 calls between 2016-2025, primarily concerning parking violations (with multiple reports of vehicles blocking driveways and bike lanes) and occasional issues with graffiti and sidewalk cleaning. A notable planning record from 2015 addressed the removal of an unauthorized dwelling unit with street access, specifying that only permitted half-baths measuring a maximum of 25 square feet were allowed. The building's overall record suggests active management of maintenance and compliance issues, although some historical violations and unauthorized modifications have occurred.
