139-141 Pfeiffer St, San Francisco, CA 94133

The property at 139-141 Pfeiffer Street is a three-story, two-unit multi-family residential building constructed in 1906, currently owned by the Guichet Family Trust. The building has undergone several significant renovations and safety upgrades over the years, most notably in 2016-2019, when substantial improvements were made including the addition of an upper floor and roof deck, complete interior remodels of kitchens and bathrooms, installation of a comprehensive fire sprinkler system, total rewiring of the house with new sub-panels, and the implementation of radiant heating. The roof deck addition in 2016 sparked a building complaint about permit violations and safety concerns, though this issue was ultimately resolved.

Earlier complaints from 2000-2001 regarding unauthorized deck and stair construction were also addressed and abated. More recent improvements include street space and sidewalk work in 2019, and the resolution of a lead paint safety violation in 2013. The building's major systems were thoroughly upgraded during the 2018-2019 renovation period, including plumbing improvements with new kitchen sinks, laundry facilities, and bathroom fixtures, though some permits were marked expired.

The property has experienced minimal recent issues, with only routine municipal service calls recorded in 2023 relating to street cleaning activities. Historical records show a brief period in 1997 when there was a complaint about garage use for business purposes, but this was promptly resolved. The building's significant renovation period from 2016-2019 appears to have brought it up to modern safety and compliance standards, with particular attention paid to fire safety through the installation of a complete sprinkler system with monitoring controls, and comprehensive electrical and plumbing upgrades throughout the property.
