1717 Mason St, San Francisco, CA 94133

The three-story, 8-unit apartment building at 1717 Mason Street in Russian Hill, owned by Edward G Newell and Andreas G, has undergone significant improvements since its 1927 construction. Most notably, the building added a new dwelling unit (unit 8) in 2019, which was completed with comprehensive upgrades to its fire safety systems, including a new fire sprinkler system and an advanced fire alarm system with sprinkler monitoring. The building completed its mandatory soft-story retrofit, achieving Tier 3 compliance with a Certificate of Final Clearance issued.

Recent improvements include substantial unit renovations in 2018-2019, particularly for units 6 and 7, featuring updated kitchens, bathrooms, and electrical systems. The property has maintained active compliance with fire safety requirements, though it has experienced several violations related to alarm systems and boiler maintenance in the past, including a 2020 violation for the alarm system that was subsequently resolved. The building's history includes regular routine inspections dating back to 1999, with the most recent occurring in 2015, when multiple fire safety issues were identified and subsequently addressed, including problems with smoke enclosure door closers, carbon monoxide alarms, and fire escape ladders.

A $40,000 tenant buyout occurred in September 2017 involving two tenants. The property has also demonstrated proactive maintenance of its infrastructure, including a 2018 terra cotta flue tile replacement with a metal chimney system, hydronic heating boiler installation, and various plumbing upgrades. Street space permits have been regularly obtained for exterior work, and the building's recent permits have primarily focused on occupancy verification and no physical changes to the structure. The property provides adequate common open space and bike parking, meeting and exceeding current zoning requirements.
