Siena: Guard-Gated · 55+ Active Adult Living in Las Vegas

Siena is Summerlin's flagship guard-gated 55+ active adult community, located in the Summerlin South Association. Developed by Shea Homes beginning in 2000, Siena spans approximately 270 acres and contains over 1,200 homes, making it one of the largest and most established age-qualified communities in the Las Vegas Valley. The community is anchored by a 30,000-square-foot private clubhouse — the Siena Clubhouse — which serves as the social, fitness, and recreational hub for residents.

Homes in Siena range from approximately $400,000 for smaller single-story patio homes to over $900,000 for the larger premium models in Sun Colony at Siena, the community's most upscale section. The architectural style is uniformly single-story desert contemporary and Mediterranean, with low-maintenance landscaping and open floor plans designed for active adult living. Most homes feature 1,500 to 3,200 square feet with 2–3 bedrooms, gourmet kitchens, and covered patios.

The Siena Clubhouse is the community's crown jewel — a resort-caliber facility with an indoor pool, outdoor resort pool, state-of-the-art fitness center, tennis courts, pickleball courts, card rooms, arts and crafts studios, a demonstration kitchen, and a full calendar of organized social activities, clubs, and events. The HOA maintains all front-yard landscaping, exterior painting, and common areas, allowing residents to focus on the lifestyle rather than home maintenance.

Siena's guard-gated entry distinguishes it from other 55+ communities in the valley, including the much larger Sun City Summerlin (which is not guard-gated). For active adults who want the Summerlin address, the security of a staffed guard gate, and a vibrant social infrastructure without the scale of a Sun City, Siena is the clear first choice.
