York Harbor sits on the southern Maine coast where the York River meets the Atlantic. It's a village within the larger town of York, serving a small year-round population alongside a much larger seasonal one. Of 256 housing units, only 102 are occupied full-time. The other 154 sit vacant, with 124 designated for seasonal or occasional use. That's 48% seasonal vacancy, the mark of a summer colony.
The York Harbor post office maintains 375 PO Boxes for just 102 year-round households. That 3.7:1 ratio exists because this is a PO Box Only Zone. There's no alternative delivery here. Summer residents need boxes to receive mail at their vacation homes. Year-round residents need them because carrier delivery doesn't exist. The post office on York Street handles everything.
Median age here is 60.9 years, among the oldest in Maine. Median home values reach $706,100, more than triple the state median. Nearly 80% of housing units were built before 1939, giving the village its historic New England character. This isn't a new resort development. York Harbor has been a summer destination for wealthy families since the Victorian era.
Owner-occupied homes outnumber rentals roughly 3 to 1 (79 vs 23). Per capita income is $61,828. The handful of year-round workers commute by car, with some using public transit. York Harbor functions as a residential enclave within the broader York community, its post office serving as the only mail access point for both the permanent population and the seasonal visitors who arrive each summer.
York Street is the post office address. All ZIP+4 records route through this single location.
