Ambassador Hotel

The Ambassador Hotel project is a historic rehabilitation of an unreinforced-masonry SRO building in San Francisco’s Tenderloin district, executed for the Tenderloin Neighborhood Development Corporation (TNDC). This effort not only preserves an important community asset but brings significant upgrades to enhance safety, accessibility, and livability for its long-term residents.

As part of the renovation, the work includes:

• Seismic strengthening with a steel horizontal bracing system, new concrete foundations, and reinforcing walls
• Structural enhancement of street-facing storefront steel frames to correct existing deficiencies
• Conversion of 14 units into 100% accessible apartments, meeting or exceeding mobility standards
• Full interior upgrades: new plumbing fixtures, finishes, ventilation, and electrical systems
• Modernization of radiant heat systems, wet bars, and plumbing in all units
• Elevator modernization, new fire alarm system, and upgrades to building security and WiFi
• Exterior and common area renovations, including a remodeled entry lobby with ADA/UPS-compliant mailboxes
• Safe improvements to the rear courtyard terrace: new concrete topping slab, egress paths, and security lighting

This project strengthens an aging building while preserving its historic presence in the Tenderloin, enabling it to continue serving vulnerable populations with dignity, accessibility, and modern building standards.
