4116-4118 17th St, San Francisco, CA 94114

The Lakamp Family Trust property at 4116-4118 17th Street is a two-unit, two-story multi-family residential building located in the Corona Heights neighborhood. Built in 1900, this flats/duplex structure has undergone several significant structural and safety-related improvements over the past few years. Most notably, there is an urgent plumbing issue that requires attention, as evidenced by a broken house trap violation filed on August 23, 2023, observed by SFPUC Sewer Operations, which has generated health and sanitation concerns.

Recent structural work includes the removal and replacement of a damaged retaining wall in March 2022, though this work appeared to require corrections, as shown by the subsequent November 2022 plumbing permit for the same retaining wall project. The building has a documented history of foundation work, with a front brick foundation replacement project filed in December 2019 at a cost of $50,000. The property has seen various interior improvements, including a substantial renovation in 2015 involving cabinetry replacement, rewiring, flooring, painting, and bathroom remodeling, alongside corresponding plumbing and electrical updates.

Earlier renovation attempts from 1992-1994 show the building has undergone multiple updates over its long history, including kitchen repairs, wall modifications, and various foundation-related work. While the building has experienced a number of permit applications and renewals in the early '90s related to interior modifications, most recent activity has focused on structural improvements and necessary repairs to maintain building safety and compliance. The property has also faced some external maintenance challenges, with numerous recent 311 calls (primarily in late 2024) regarding garbage and debris on or near the property, though most of these were resolved without requiring any specific actions.
