447-449 Utah St, San Francisco, CA 94110

The property at 447-449 Utah Street is a two-unit, two-story residential building located in Potrero Hill, San Francisco. Built in 1902, this flats/duplex-style building has undergone several significant improvements over the past decade to maintain and enhance its structural integrity and living conditions. Most notably, in 2020, the building received seismic strengthening through voluntary anchor bolting and plywood installation at the first floor level, along with facade restoration and window replacements costing a total of $30,000.

Previous improvements include a substantial upper unit renovation in 2014 (valued at $42,000) that included kitchen and bathroom remodeling, skylight installation, and structural modifications, followed by a bathroom remodel in 2016. The building's systems have also been upgraded, with the installation of a new two-meter 200A service in 2018, solar PV modules in 2013, and various plumbing improvements including bathroom renovations and furnace replacement between 2013-2016. The property has experienced minimal serious issues, with only two notable historical complaints on record: one from 2016 regarding unpermitted construction work (status not active) and a 1995 complaint about an attached structure and safety concerns (resolved in 2003).

Recent 311 calls primarily relate to street cleaning and debris management outside the property, with multiple reports in 2022-2024, though these appear to be related to external conditions rather than building-specific issues. The building participated in the Section 134 Rear Yard Variance process, which was approved, allowing for specific modifications to the property's rear yard area. The property's maintenance record indicates regular upkeep and improvements, with no recent complaints or violations on file, suggesting responsible ownership and compliance with building codes.
