Much of Parker County is unincorporated with few local rules

Get out past the city limits and there's no zoning to worry about. Texas just never handed counties the power to zone unincorporated land. So on a piece of rural Parker County acreage, what you can and can't put up isn't decided by some land-use map down at the courthouse. It comes down to your deed restrictions, whatever rules came with the subdivision plat, and state law. That's it.

Inside the towns it's a whole different animal. Weatherford, Aledo, Springtown, and Azle each zone the ground within their limits, and each one reaches a little past the edge through what's called an ETJ, or extraterritorial jurisdiction. It's a buffer ring around the city where it still gets a say in how raw land gets carved up into lots, even though that land isn't technically in town yet.

And that ring catches plenty of people off guard. You can be standing on a parcel that feels every bit as rural as the next pasture over, surrounded by nothing but fence line, and still be sitting inside a city's ETJ, which quietly changes the rules on how you're allowed to split it. A title company or the city's planning desk can tell you whether a tract you mean to divide falls inside one before you ever pay a surveyor to draw lot lines.
