9 rules for unincorporated Buncombe County, North Carolina.
Verified from official government sources
Buncombe County (NC) has no ordinance capping grass or lawn height on private residential lots. North Carolina counties have limited nuisance authority over overgrown vegetation, so tall grass is generally not a county violation. Inside Asheville and other towns, the municipality sets its own rules.
Buncombe County does not require a permit to trim or prune trees on private residential property. Routine trimming is unregulated by the county. Special standards apply only in the Steep Slope and Protected Ridge overlay districts, and NC utility/road rules govern trimming near power lines and public roads.
Buncombe County does not require a permit to remove trees on ordinary private property. The real county tree standards apply in the Steep Slope and Protected Ridge overlay districts, where required screening trees must stay within 50 feet of the downhill side of a structure and follow native-species and spacing
Buncombe County Protected Ridge & Steep Slope Overlays, Screening Plan standards
All trees must be within 50' of the downhill side of the structure, and must consist of varying, native species. No single species can comprise more than 50% of the plantings, and must be between 10' to 30' apart. Existing credit trees must be flagged to count.
Buncombe County (NC) does not have a general weed-abatement ordinance for private residential property. Overgrown weeds on private lots in the unincorporated county are usually not a county violation. Cities regulate weeds within their limits, and NCDOT handles roadside vegetation.
Buncombe County has no standing landscaping water-restriction ordinance. Outdoor watering limits kick in through the water utility (Asheville water system) and North Carolina's drought-response system, which sets county restriction stages each week based on the U.S. Drought Monitor at ncdrought.org.
Rain barrels and cisterns are legal in Buncombe County (NC). North Carolina does not restrict residential rainwater collection, and the county encourages it as a stormwater and drought measure. Larger cistern plumbing tied into a home may need to meet the state plumbing code.
Buncombe County does not require native landscaping on ordinary lots, but in the Steep Slope and Protected Ridge overlays, required screening trees must be native species with no single species exceeding 50% of the plantings. The county Cooperative Extension also promotes native, drought-tolerant plants.
