Mount Gretna sits in Lebanon County, Pennsylvania, covering just 0.71 square miles. With a median age of 60.1 years, this small community has a distinctly retirement-focused character. The 847 residents live in 426 households, but 30.7% of the 649 total housing units are seasonal properties (199 units). This is a place people come to for summer retreats and retirement living.
The post office maintains 475 PO Boxes for 426 households. That's a 1.12x adoption rate, meaning the post office serves both local residents and seasonal homeowners who maintain year-round mailing addresses. This is a PO Box Only Zone. There's no alternative mail delivery across the community, though two rural carrier routes do serve the area.
Street names tell two stories. Numbered streets (1st through 8th) form the historic grid, while college-themed avenues (Harvard, Yale, Princeton, Temple, Lafayette, Lehigh, Columbia) hint at the community's educational character. Indeed, 73.4% of adults hold bachelor's degrees or higher. This isn't typical for rural Pennsylvania. With a median home value of $360,000 and median household income of $123,333, Mount Gretna is an affluent enclave where 21% of workers have the flexibility to work from home.
The population breakdown shows just how retirement-focused this ZIP is. Only 11 residents are under 18, and only 11 are aged 18-24. The community is 93% white (791 of 847 residents), with very small Asian and Hispanic populations. Of the 426 occupied homes, 350 are owner-occupied and just 76 are rentals. Over 80% of the housing stock (531 units) was built before 1939, giving Mount Gretna its historic character.
