103-105 Alta St, San Francisco, CA 94133

The three-story multi-family residential building at 103-105 Alta Street in Telegraph Hill, owned by Jeremiah and Jacqueline Robison, is a two-unit flats and duplex structure built in 1909. The property underwent significant renovations between 2009-2011, including comprehensive interior upgrades to both units, window replacements, and a full seismic upgrade with new plumbing and electrical systems, at a cost of $500,000.

During this renovation period, several issues were documented, including three building complaints in 2010 related to construction activities: unauthorized enclosure of open areas, work beyond permit scope, and construction dust affecting neighboring properties. Infrastructure improvements included the installation of a new hydronic heating system covering all three floors with a boiler, complete plumbing system upgrades including new drains and fixtures, and electrical rewiring of both units, all of which were properly permitted and completed. The building has experienced recurring sewer-related issues, with two documented sewage backup incidents in 2020 and 2022 involving 4-inch vent lines that required attention from PUC Sewer Operations.

The property's maintenance history shows some older permits from 1988 (kitchen renovations) and 1996 (foundation work) that are no longer active. Recent activity at the address has been limited to routine matters, including parking enforcement calls in 2020 and 2023, with the most recent significant building-related incident being the 2022 sewage backup. The area has generally maintained compliance with building regulations since the completion of the 2009-2011 renovation period, with no major complaints or permit violations recorded in recent years.
