Flagg Coastal Homes in Coronado holds California Contractor's State License #898050 and operates from 1125 Loma Avenue as the island's dedicated coastal design-build firm, having completed more than 80 custom residences since its 2006 founding. Each project moves from schematic design through construction documents with Flagg's in-house design studio coordinating structural and aesthetic details alongside island architecture firms such as Christian Rice Architects, Inc. for permit-ready drawings that satisfy Coronado's stringent historic and coastal design-approval process. The firm earned national visibility in 2014 when Coastal Living magazine selected a Flagg-built residence on Sunset Park as its National Showhouse, drawing over 6,000 visitors to tour the completed home — a project that codified the California-coastal vocabulary Flagg applies to oceanfront and bayfront parcels across Coronado Island. Site work on the island's salt-air-exposed lots demands drought-tolerant hardscape and landscape integration, which Flagg coordinates with specialists including San Diego Landscape Solutions for exterior completion on delivered properties near Coronado Beach and along Silver Strand Boulevard. Turn-key scope encompasses foundation-to-finish general contracting, interior design through Flagg Design Studios, and specialty subcontracting for oceanfront structural elements including corrosion-resistant steel framing, impact-rated glazing systems, and marine-grade exterior cladding engineered to withstand the Coronado Beach salt environment.
