Of the 6 total housing units recorded in the 2020 census, half sit vacant for seasonal use. That 50% seasonal vacancy rate confirms what the PO Box count already suggests: this isn't a traditional residential community. It's a getaway destination where most property owners maintain a mailing address for the one or two weekends a month they actually show up.
The post office on FM 1189 serves as the only delivery option for the entire area. Street delivery doesn't exist here. Every resident, whether full-time or seasonal, relies on a PO Box for mail. In communities like this, that's not an inconvenience but a practical solution for properties that sit empty most weeks of the year.
Parker County's lake country attracts this kind of development. Dennis sits just miles from Lake Weatherford, where property owners from Fort Worth and the wider Metroplex maintain fishing cabins and weekend homes. The median age of 19 skews young, likely reflecting families with children who visit during summer months rather than retirees seeking solitude.
Just one road defines this community: FM 1189, the farm-to-market highway that connects Dennis to the wider Parker County area. The minimal street infrastructure reflects the community's character as a collection of weekend properties rather than a developed subdivision.
