Benton County's high desert makes native and drought-tolerant landscaping a natural fit, and no local rule forces a grass lawn on an existing lot. You may plant shrub-steppe natives freely, but listed noxious weeds must still be controlled.
Xeriscaping and native planting suit the Columbia Basin's arid climate, and neither the county nor the Tri-Cities requires a turf lawn on a finished residential lot, so sagebrush-country natives, bunchgrasses, and pollinator beds are welcome and water-wise. Washington, unlike some arid Southwestern states, has no statute barring HOAs from requiring conventional lawns, so subdivision covenants remain the real constraint. One duty survives any landscaping choice: under RCW 17.10.140 owners must eradicate Class A noxious weeds and control listed Class B and C species, so a native or low-water yard still cannot harbor listed invasives.
None from the county or state for native or xeriscape planting. A neglected planting that harbors listed noxious weeds triggers the mandatory-control duty and possible Weed Board abatement. HOA covenants are enforced by the association.
