Ada County does not require any particular landscape plants and does not ban native or xeric plantings. As long as growth is not an overgrown-weed nuisance or a designated noxious weed, residents may choose water-wise native landscaping.
There is no county mandate to plant lawn versus native species, and no prohibition on drought-tolerant or xeriscape landscaping on private property. The two limits that matter are the nuisance ordinance (Title 5, Chapter 9), which targets hazardous overgrown weeds and grasses, and the noxious-weed law (Chapter 8 plus Idaho Code Title 22, Chapter 24), which requires controlling designated noxious weeds. Native bunchgrasses, sagebrush-steppe and pollinator plantings are fine if kept from becoming a fire hazard or harboring noxious weeds. Subdivision covenants and city landscape standards may still require minimum landscaping or approved plant lists.
No county fine for native landscaping itself; enforcement only arises if the planting becomes a weed nuisance or contains listed noxious weeds that go uncontrolled.
