Augrented Insights Report

The 18-unit, three-story apartment building at 1421 10th Avenue in the Inner Sunset, owned by Nam Investments and built in 1963, has undergone significant renovation and safety upgrades in recent years, including the completed soft-story retrofit (Tier 2) with a steel moment frame, and recent re-roofing work. The building conversion project added five new ADU units by converting parking spaces and storage areas, bringing the total to 23 units, with comprehensive upgrades to fire safety systems throughout.

Recent complaints from 2024 highlight ongoing maintenance concerns, including a fire exit door malfunction, security gate issues, and various interior conditions in Unit 204. Multiple fire safety violations have been recorded, with the most recent sleeping area requirement violation issued in November 2023.

The building has experienced recurring issues with emergency exit access, window safety, and security features, as evidenced by complaints regarding fire escape ladder functionality and window bars. While several building improvements have been completed, including new fire systems, electrical upgrades, and plumbing work, there remains a pattern of maintenance-related complaints, particularly regarding interior surfaces and building security features. The property has also generated numerous parking enforcement calls, suggesting ongoing challenges with parking management in the area.
