About
Riddlewood is a mid-century single-family subdivision in Middletown Township, Delaware County, built between approximately 1953 and the late 1950s on 218 acres purchased from the estate of racehorse owner Samuel D. Riddle — the man behind Man o’ War and Triple Crown winner War Admiral. Developer Arters Brothers, working with architect George Hay, planned 230 homes across a 190-acre portion of the tract; the community was recognized in 1954 by the National Association of Home Builders as one of the ten finest home developments in the United States, and was featured multiple times in Better Homes and Gardens magazine. Streets carry the names of Riddle’s most celebrated horses — Man O’ War Drive, War Admiral Lane, War Trophy Lane, Soldier Song Lane, and others — and the Riddlewood Swim Club, a non-profit member-owned pool at 56 War Trophy Lane, has operated continuously since 1957 alongside a ball field and basketball and volleyball facilities on community-retained land.

What Makes This Distinct
No formal homeowners association (HOA) has been identified for Riddlewood in public records or public filings; the community’s organized social and civic functions are conducted through the voluntary Riddlewood-Sunnybrae Community Association (RSCA), which means there are no mandatory dues, deed-restriction enforcement fees, or HOA transfer requirements at settlement — a structural distinction buyers and sellers should verify through title.
