Neither Hamilton County nor Chattanooga requires homeowners to plant native species, and there is no ban on turf lawns. Native and pollinator plantings are encouraged. Zoning landscape standards mainly govern required buffers, parking-lot planting, and new development, not private yard plant choice.
Tennessee has no statewide mandate on native-plant landscaping, and Hamilton County sets no county-wide requirement for homeowners. Chattanooga's zoning landscape provisions, administered through the Regional Planning Agency, focus on required landscaping for development, parking lots, screening buffers, and street-tree planting, not on the plant palette of a private residential yard. The city and regional programs encourage native and pollinator-friendly plantings for stormwater and canopy benefits, but this is guidance, not a rule. Homeowners are free to choose native or ornamental species. HOAs may impose their own landscaping standards, which the city and county do not enforce. We cite honestly: no local native-plant requirement applies to private yards.
No penalty exists for choosing non-native plants in a private yard. Development landscape violations (missing required buffer/street trees) are enforced through zoning and site-plan review.
