700 Mason St, San Francisco, CA 94108

The five-story, nine-unit multi-family residential building at 700 Mason Street, owned by Abuyaghi Properties LLC, was constructed in 1911 and has undergone various maintenance and compliance efforts over the years. The property has experienced several significant issues between 2011-2013, including multiple housing violations related to plumbing (kitchen sink waste pipe issues), fire safety (fire escape maintenance), and general maintenance concerns. In 2014, important earthquake safety compliance issues arose when the building was noted as part of the mandatory soft story retrofit program, resulting in violation notices for failure to submit required documentation and incur monthly monitoring fees.

The building's systems have received multiple upgrades and inspections, including a new steam boiler installation in 2013 and various plumbing repairs between 2011-2015. Recent activity includes a 2023 complaint about early morning construction work in the rear yard area, though this issue is currently listed as not active. The building's fire safety systems have undergone regular inspections, with violations noted in 2011 for combustible storage in exit paths and electrical concerns, though these were subsequently corrected.

Fire-related incidents recorded at the address appear to be primarily for service calls and assistance, with no civilian injuries reported. More recent 311 calls from January 2025 primarily relate to street and sidewalk cleaning issues, including reports of garbage and debris, while older records from 2014-2015 show concerns about boiler permit renewals and a possible illegal basement unit that were resolved. The building's maintenance history indicates ongoing compliance efforts, with most violations being addressed and closed, though some historical permits from the 1980s and 1998 for parapet bracing and various structural improvements have expired.
