1046 Mason St, San Francisco, CA 94108

The 8-unit, 3-story multi-family residential building at 1046 Mason Street in Nob Hill, constructed in 1910, has undergone several significant improvements and faced multiple maintenance challenges in recent years. Most notably, a fire alarm replacement system was filed for installation in May 2023 to comply with San Francisco Fire Department regulations. The building has seen substantial electrical upgrades, including a 2017 replacement of the 100-amp overhead service with a 200-amp system and new subpanels, as well as a significant renovation of Unit 4 completed in 2020 that included new kitchen cabinets, plumbing fixtures, and electrical work costing $65,000.

The building previously experienced multiple water-related issues in 2016, with several violations related to water damage, including leaks, interior surface damage, and lead paint concerns, though these were officially abated by June 2019. Additional concerns during this period involved insect infestation, damaged ceilings, and electrical outlet problems. Recent years have shown continued attention to building systems, with plumbing improvements including a new 50-gallon water heater installation in 2019 and compliance upgrades to prevent water damage.

There have been periodic maintenance issues, such as a hardwood floor buckling in 2020, broken light fixtures, and various other building maintenance concerns, though most have been promptly addressed. The property has experienced several fire safety-related incidents, including false alarms and wiring problems, but no civilian injuries have been reported. Recent 311 calls primarily relate to standard municipal services such as street cleaning and parking enforcement, with no major building-related complaints emerging since 2020, suggesting improved maintenance response.
