Research a Property
What you can legally build on a property or use it for depends on many factors. Start by checking permit jurisdicton. If it's in unincorporated Thurston County, check its zone. If planning to build, you'll also want to check water sources, gopher soils and more (see checklist). Use the County's online resources to research for free, or hire experts.
