2947-2949 Folsom St, San Francisco, CA 94110

The two-story multi-family residential building at 2947-2949 Folsom Street, located in San Francisco's Inner Mission, was constructed in 1907 and currently contains four units, though historical records indicate it was formerly converted from two units following a significant renovation in 1996 that addressed illegal units. The property has undergone several major improvements over the years, with the most recent being a 200-amp electrical service upgrade completed in 2021 and the installation of a solar system in late 2016 featuring 31 roof-mounted PV modules.

The building's maintenance records show recurring attention to roofing issues, with multiple re-roofing projects documented in 1998, 2016, and the more recent electrical upgrades including solar infrastructure work in 2016. The property has experienced some building code enforcement activity, including a 1989 violation related to machinery removal and a 1997 complaint concerning unauthorized construction that was quickly resolved.

Historical improvements include a kitchen remodel in 1991 and a second-floor bathroom renovation in 2002, though some earlier permits have expired. Recent activity around the property has primarily involved street-related issues, with several reports of illegal parking in 2022-2024 and multiple street cleaning concerns regarding waste removal. The building's current owner, Patrick O'Connor, has maintained compliance with recent electrical upgrade requirements and solar installations, indicating ongoing investment in the property's infrastructure.
