River Grant is a 32-unit townhouse condominium community in the Contoocook portion of Hopkinton, located along Park Avenue and River Grant Drive. The Town of Hopkinton identifies the development as a 32-unit condominium community in its hazard-management inventory. Its location is particularly convenient because residents can walk or make a short trip into Contoocook Village for shopping, restaurants, schools, the post office, library and other community services.

The development includes multiple construction phases, with public records showing some homes dating from approximately 1987 and newer sections constructed around 2006. Units are generally two-story townhouses with wood-frame construction, vinyl or wood siding, garages or dedicated parking, basements and approximately 1,200–1,700 square feet of living space. Recent examples include two-bedroom units around 1,300 square feet, often with gas fireplaces, three-season porches and central air conditioning.

River Grant's lifestyle is centered on convenient townhouse living rather than extensive recreational facilities. Association services reported in recent listings include landscaping, grounds maintenance, plowing and trash removal, with common acreage and maintained private roads forming the principal shared infrastructure. Recent monthly fees are generally around $290–$300, although individual listings can vary.

The community's greatest amenity is its location. River Grant is within walking distance of Contoocook Village, providing unusually good access to everyday services for a suburban condominium development. Hopkinton schools are nearby, Concord is readily accessible by Route 202/9 and I-89, and the surrounding Contoocook River region provides opportunities for walking, cycling, fishing and other outdoor activities.
