235-237 Pierce St, San Francisco, CA 94117

The two-unit residential building at 235-237 Pierce Street, owned by James Cavenaugh and built in 1895, has undergone several significant improvements and maintenance work over the past few years. Most notably, in 2019-2020, the building received substantial window upgrades, including the installation of four new wood windows on the front façade, with a subsequent revision adding four additional back wood windows.

The property also underwent a bathroom remodeling project in 2019, converting a closet into a half bath, which included associated electrical and plumbing work. More recent maintenance includes plumbing work in July 2023 to address water service issues caused by tree roots, and the replacement of defective waste pipes in the light well in 2019. The building's recent history has seen some concerning incidents, particularly with sewage system issues in late 2024, including two separate sewage back-up incidents, one from the catch basin and another from the side sewer vent.

A significant infrastructure improvement was attempted in 2004 with a permit for replacing the staircase serving both apartment units as a secondary means of egress, though this permit expired without completion. Historical records show earlier improvements including the installation of a new fireplace in 1994, but some planning records indicate disapproval of a variance request for constructing a third unit on the ground floor with off-street parking. The property has experienced various neighborhood-related issues in recent years, including multiple parking enforcement calls between 2023-2024 for sidewalk blocking and driveway obstruction, though most of these cases resulted in officers being unable to locate the violations.
