1131 Montgomery St, San Francisco, CA 94133

The two-unit residential property at 1131 Montgomery Street in Telegraph Hill is a one-story building constructed in 1906, currently owned by Prt Holdings LLC. The building's documented history reveals several significant proposed development projects between 2006 and 2010, focusing on substantial expansion and modernization efforts.

These plans included constructing a new three-story single-family house behind the existing structure, replacing and restructuring the original foundation, and expanding the garage to accommodate three parking spaces. Additional proposals aimed to raise the existing cottage and develop new living spaces behind and above it, with multiple planning records indicating this was to be undertaken by Wessel Associates. The only permit work on record for this property was completed in 2007, consisting of a bathroom remodel and washing machine plumbing installation.

Two building permits from 1982 are noted in the record, but both were withdrawn and likely represent outdated or no longer relevant applications. While the planning records suggest ambitious development plans for the property, there is no subsequent permit activity or construction records to indicate these proposals were ever executed. The most recent activity on record is the 2007 plumbing work, and given the significant time that has elapsed since any major work was proposed, it is worth noting that none of the planned multiple-unit expansions or substantial renovations appear to have been carried out based on available permit records through October 2023.
