Calaveras County, CA Landscaping Rules: Native Plants (2026)

There is no requirement for homeowners in unincorporated Calaveras County to plant native species in their yards. For development projects, however, the County's adopted Zoning Code (effective August 15, 2024) includes Chapter 17.20 Landscaping, with Section 17.20.030 covering Water Efficient Landscaping and Irrigation and Section 17.20.040 covering Areas to be Landscaped. These provisions implement California's water-efficiency framework, which steers required landscaping toward climate-appropriate, low-water plant material and efficient irrigation rather than thirsty turf. Calaveras County sits in the Sierra Nevada foothills, dominated by native blue oak, valley oak, and interior live oak woodlands transitioning into ponderosa pine forest, and native oaks receive special protection through the County General Plan oak policies (COS 3.5, 3.6, 3.9) for discretionary projects. Resources such as UC Cooperative Extension Central Sierra and the California native plant movement (Calscape) promote foothill-native, drought-tolerant, and fire-wise plantings. While not mandated for individual homeowners, choosing native and low-water species aligns with the County's water-efficiency landscaping standards, defensible-space fire goals, and drought-stage irrigation limits set by local water districts.
