Summary
Guilford County does not mandate native plants for private yards, but its Unified Development Ordinance sets planting standards for required landscape and buffer yards on larger developments, including canopy, understory, and shrub counts.
Canopy trees must be a minimum of eight (8) feet high and two (2) inches in caliper, measured six (6) inches above grade, when planted....Understory trees must be a minimum of four (4) feet high and one (1) inch in caliper, measured six (6) inches above grade, when planted.
Full Breakdown
For single-family and two-family lots, the county imposes no plant-species requirement, so homeowners may plant natives or ornamentals freely. On commercial and larger multi-family projects, UDO Section 6.2 requires specified planting yards with minimum tree and shrub densities, and sets nursery-stock standards: canopy trees at least eight feet high and two inches in caliper when planted, understory trees at least four feet and one inch caliper. Preserving existing native tree stands can satisfy these requirements, and older trees are prioritized. Selecting native, drought-tolerant species is encouraged but not compelled.
Violations & Fines
Non-compliant required plantings on regulated development can block certificates of occupancy; UDO enforcement (Subsection 10) applies until landscaping meets the approved plan.
