4084-4086 18th St, San Francisco, CA 94114

The three-story mixed-use building at 4084-4086 18th Street, owned by Rickenbacher Matz LLC, was built in 1906 and contains three residential units plus commercial space. The property has a significant history of fire-related incidents and violations, most notably a fire in 2011 that caused substantial damage to a beauty salon, prompting extensive repairs including the installation of a new fire sprinkler system and related safety improvements costing over $25,000. More recently, in 2023, there were two shared spaces complaints regarding the outdoor area and one alarm system issue, though all were resolved or found to have no merit.

The building has undergone several important maintenance and safety upgrades, including a sewer line repair in 2015, replacement of dryrot base plates in 2013, and the installation of an iron gate in 2017 to address security concerns about loitering. The property has faced multiple compliance challenges over the years, including several building complaints in 2009-2010 regarding unpermitted bathroom construction, unsafe conditions on the back patio, and disabled access violations. There have been recurring concerns about proper permits for outdoor seating areas, with a significant complaint in 2011 regarding unauthorized construction of a roof structure with electrical and gas lines.

In 2022, a complaint was filed regarding plumbing issues, dilapidated structure, and disabled access restrooms, though this is listed as not active. The property has also experienced various infrastructure improvements, including gas line replacement, plumbing upgrades, and electrical work, as evidenced by numerous building permits from 2009 to 2017. Recent 311 calls from late 2024 indicate ongoing issues with garbage and debris on the property, including reports of human waste or urine, though these are street-related rather than building-specific complaints.
