3090 Market St, San Francisco, CA 94114

The two-unit residential building at 3090 Market Street in Corona Heights is a two-story flats and duplex structure built in 1900, currently owned by Ryan Timothy C & Inverarity. The building has undergone several significant improvements over the past two decades, including major plumbing work in 2023 with the replacement of the house trap, and substantial foundation work in 2019 involving concrete foundation and floor improvements.

Other notable maintenance includes a new roof installation in 2013, repair of dry rot in 2014, and structural repairs including work on stairs in 2000. The property's utilities were upgraded with an underground electrical conversion to 150 amps in 2004 and a gas line extension with meter relocation in 2019. Recent infrastructure-related incidents near the property include two reports of downed trees (March 2023) and multiple maintenance requests regarding street conditions.

There have been several environmental maintenance issues in the vicinity, including graffiti removal and resolution of defaced signs in October 2023, as well as various street cleaning requests between 2022-2023. The building's legal occupancy and two-unit status was officially documented in 2018 through an administrative permit, and there were attempts to obtain variances for rear yard deck and staircase modifications, though these requests were withdrawn or cancelled. The property has experienced some recent utility-related disturbances, including issues related to dirt left from a PG&E project in December 2023, though this was subsequently resolved.
