Costa Diamante is the only single family beachfront home community situated along Sandy Beach in Puerto Peñasco. Positioned between high-rise condo resorts, the development consists of 112 single-family lots featuring custom beachfront villas, ocean-view detached homes. Built along paved cobblestone streets with underground utilities, properties range from two-bedroom single-level layouts to two-story floor plans exceeding five bedrooms.

Residences typically incorporate attached single- or double-car garages, enclosed entry courtyards, covered ocean-facing patios, and roof terraces. Exterior aesthetics often reflect Mexican and Spanish Colonial architectural influences, characterized by warm stucco finishes, red barrel tile roofs, stone accents, and decorative archways.

Community amenities center around a shared recreational common area that includes a swimming pool, outdoor hot tub, basketball court, bocce ball court, children's playground, and landscaped green spaces. Direct beach access gates connect residents straight onto Sandy Beach. The community is strictly residential with no internal commercial venues, though dining options such as Colin's Cantina and nearby resort restaurants are within walking distance. Secured by a gated entry with 24-hour guarded security patrols, Costa Diamante provides a low-density alternative for buyers seeking single-family home ownership, private garage storage, and direct beach proximity.
