825-829 Mason St, San Francisco, CA 94108

This three-story multi-family residential building, located in downtown and built in 1910, contains four units and is currently owned by Trust C. The property has experienced ongoing fire safety maintenance issues over the past several years, with eight documented fire code violations between 2021 and 2025, including problems with fire extinguishers, fire escape maintenance, and various other safety requirements.

Most recently, in December 2024, there were multiple fire code violations issued that remain open, including issues with records, UL certification, and a roof exit requirement. The building's maintenance history shows some attention to structural issues, notably in 2010 when repairs were made to third-floor exit stairs and garage ceiling holes after a notice of violation was issued, though several violations from a 2016 routine inspection regarding stairs, fire safety equipment, and structural maintenance requirements remain active.

While the building has undergone some significant improvements, such as reroofing in 2005, the recurring nature of fire safety violations and the presence of multiple active violations as of 2025 suggest ongoing maintenance challenges. The property has experienced routine fire incidents typical of older buildings, including false alarms, system malfunctions, and a contained cooking fire, though none resulted in civilian injuries. Regular inspections and permit validations indicate ongoing oversight by housing inspection services, though some records remain open regarding fire system maintenance and documentation requirements that appear to be associated with an adjacent address (999 California St).
