1313-1315 Mason St, San Francisco, CA 94133

The three-unit, three-story multi-family residential building at 1313-1315 Mason Street in Nob Hill, owned by John J Thrall, has a construction history dating back to 1909. The building has undergone several significant maintenance and improvement projects over the past decades, including a $14,000 reroofing project completed in 2015, kitchen and flooring renovations in 1996, and various plumbing updates including water heater replacement in 2008.

Notably, a recent complaint was filed in July 2023 alleging unauthorized window replacement and painting work, which is currently marked as active. The property has experienced several code compliance issues, most notably in 2008 when multiple violations were documented regarding plumbing permits and water temperature requirements, though these were resolved by December 2008. An unauthorized fence installation complaint from 2003 was also addressed.

Recent maintenance efforts include regular roof maintenance, with historical records showing multiple roof work permits in 1996 and 2015. The building's environment has seen recurring street cleaning needs, with multiple 311 calls for loose garbage between 2022 and 2024, though these are typical urban maintenance issues. The most recent building complaint regarding unauthorized work marks the first significant compliance issue in many years, following a period of generally regular maintenance and upkeep.
