450-454 Waller St, San Francisco, CA 94117

The three-unit multi-family residential building at 450-454 Waller Street in Hayes Valley, owned by 450 Waller LLC, has undergone significant renovations since 2018. The three-story flat, built in 1905, has seen comprehensive interior improvements including multiple bathroom additions and kitchen remodels. Between 2018-2021, there were several substantial renovation projects totaling over $140,000, including structural changes, electrical rewiring of a two-bedroom unit, plumbing updates with new fixtures and drains, and the addition of skylights.

Despite these improvements, the building experienced notable maintenance issues in early 2019, with complaints about heating problems, plumbing leaks, and rodent infestation, as well as concerns about unauthorized construction work and potential mold issues. These problems were reportedly addressed by May 2019. The property has a history of building violations from 2008-2011, including issues with fire safety equipment, ceiling repairs, floor coverings, and other structural concerns, all of which were documented as abated by December 2011.

More recent concerns have emerged regarding the building's exterior and surrounding areas, with multiple 311 calls in 2024 regarding sidewalk conditions, garbage, and tree root issues. Planning records show attempts to modify the rear yard stairs, with one application withdrawn and another approved for light well infill work. The most recent building permits indicate continuing maintenance and improvement work, though there are currently open calls regarding sidewalk conditions and tree-related damage as of September 2023.
