The 10-unit, 3-story multi-family residential building at 2943-2947 16th Street, built in 1921 and owned by Mission Housing Develop Cor, has undergone significant safety and infrastructure improvements over recent years. Most notably, the building completed a mandatory soft-story retrofit in 2017 (Tier 4) at a cost of $300,000, demonstrating compliance with seismic safety requirements. Between 2016 and 2019, the property received substantial safety upgrades including a new fire alarm system ($38,000) with comprehensive detection and alarm components, installation of an automatic fire suppression system over the kitchen hood ($3,500), and commercial-grade utility meter upgrades ($62,400).

The building has maintained its plumbing systems with multiple updates, including water heater replacements and backflow device installations between 2018-2020, while electrical improvements have included rewiring of the commercial space and subpanel upgrades. More recent concerns include a current active complaint from March 2023 regarding a vacant commercial space, and several encampment-related issues reported in early 2025. The building has experienced multiple fire safety inspections and incidents over the years, with the most recent fire complaint in July 2024 regarding alarm systems (condition corrected).

Historical violations from 2003 and 2011 related to fire escape maintenance, fire alarm systems, and gas utility shutoff tools were all abated by September 2011. The property has also seen regular infrastructure maintenance including water line work, sewer repairs, and boiler system updates, with the most recent plumbing complaints from 2020 regarding boiler permit renewals being resolved. Despite these issues, the building's documented history shows a pattern of addressing safety and maintenance concerns promptly, with most recent permits focusing on completing previously approved work and maintaining essential systems.
