East Dennis occupies a narrow coastal strip on Cape Cod's bay side, where 332 year-round residents share space with 292 seasonal homes. That's 60% of all housing sitting vacant most of the year, marking this as one of Massachusetts' most seasonal communities.
The post office maintains 789 PO Boxes for just 193 households, an adoption rate of 4.09 that reflects something unusual about this place. Second-home owners don't want their mail sitting on porches all winter, so they rent boxes year-round. Boaters keeping vessels at Sesuit Harbor need reliable addresses. Summer renters cycling through weekly can't depend on physical delivery. The PO Box becomes the constant in a community where population swings wildly between seasons.
Most residents live along Route 6A, the Old King's Highway that traces Cape Cod Bay through historic villages. Sesuit Neck Road reaches north toward the harbor, while Sea Street connects inland neighborhoods. The 39 street names tell a coastal story: Salt Works Road, Harbor Road, Creeks End. These aren't suburban developments but evolved lanes following 17th-century property lines.
With a median home value of $1,024,500 and median age of 67, East Dennis caters to retirees who can afford waterfront property. The 73 businesses employ 236 people, but many of those jobs vanish after Labor Day. This isn't poverty driving PO Box adoption. It's wealth, seasonal living patterns, and the practical reality that street delivery doesn't serve second homes well.
Street names reflect Cape Cod's maritime heritage and colonial history. Route 6A (the Old King's Highway) carries most delivery traffic, while roads like Sesuit Neck, Sea Street, Salt Works, and Harbor Road connect waterfront neighborhoods. Names like Cold Storage Road and Salt Works Road reference the area's fishing and salt-making past.
