Building on rural acreage in Kittitas County is a different project than building inside Ellensburg city limits or inside a resort community with design review. There is no DRC—but there is KCC Title 17 zoning, water availability documentation, engineered septic, access easements, and a Kittitas County permit process that will not accept an incomplete package.
Benchmark Custom Homes builds on A-5, A-20, R-5, CA, F-R, and CF parcels across the county—from Thorp and Badger Pocket to Manastash foothills and Cascade-edge land. This guide is the pre-construction sequence we run on every rural build.
Water availability and well feasibility
Kittitas County requires water availability documentation before a building permit submittal is accepted. That may mean an existing well with documented yield, a well share agreement, a cistern system where approved, or a new well drill with sufficient gallons-per-minute for the proposed home.
Drilling depth and cost vary by geology. Valley agricultural ground behaves differently than foothill basalt. We coordinate well drilling early—before architectural design locks in a fixture count the well cannot support.
Septic design and soil testing
Outside municipal sewer, every rural home requires an engineered on-site sewage system. Soil percolation testing, setback distances from wells and waterways, and system type (gravity, pressure distribution, mound) must be designed and permitted before construction.
Septic layout often constrains where on the parcel the home can sit—especially on sloped or rocky ground. We resolve septic before committing to a foundation location.
- Licensed OSS designer and Kittitas County Health Department review
- Setback requirements from property lines, wells, and critical areas
- Reserve area for future repair or expansion where required
Access, easements, and driveway construction
Legal access is not automatic on acreage. We verify recorded easements, shared driveway agreements, and county road frontage before purchase closes—or immediately after, if you already own the parcel.
Driveway construction on rural parcels includes culverts, base course, and sometimes significant cut/fill. Power extension from the nearest transformer adds cost and timeline that city builders never model.
KCC Title 17 zoning and permit submittal
Kittitas County Community Development Services permits unincorporated parcels at 411 N Ruby Street, Suite 2, Ellensburg WA 98926. The county operates on the 2018 IRC with Washington State amendments.
Pre-application requires water availability documentation and a preliminary site analysis. Incomplete packages restart timelines. We submit complete packages—civil, septic, well, structural—on the first pass when possible.
- A-5 / A-20: agricultural zones with density and setback rules
- R-5: rural residential on larger parcels
- CA / F-R / CF: commercial-forest and farm-forest—verify buildability before purchase
- Critical areas and geologically hazardous site review on slope and riparian parcels
