1144 Masonic Ave, San Francisco, CA 94117

The two-story, four-unit multi-family residential building at 1144 Masonic Avenue in Haight Ashbury, owned by Raul and Denise Arriaza, was constructed in 1900. The property has undergone several significant safety system upgrades over the past decade, with the most recent being a comprehensive fire alarm system replacement in June 2024 costing $13,500 to comply with fire code requirements.

In 2013, the building received a fire sprinkler monitoring system installation that included various fire safety components, and electrical work was completed to connect the sprinkler monitoring system. The building has maintained active compliance with fire safety regulations, with no outstanding violations currently on record. The property had two routine housing inspections in 2003 and 2008, which identified several security and safety issues that were promptly addressed, including the installation of smoke detectors, self-closing doors, and fire extinguisher maintenance (all abated by March 2003).

More recent activity around the property primarily consists of routine street maintenance and cleaning issues, with multiple reports of loose garbage and graffiti between 2023 and 2024, though these external issues do not directly reflect on the building's internal conditions. A new fire alarm systems complaint was filed in January 2025, though the resolution status is currently pending. The building's maintenance record shows regular attention to safety compliance, particularly regarding fire systems, with no patterns of recurring safety violations or resident complaints.
