Cary's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In Cary, North Carolina, there are 7 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Composting

Cary allows residential composting of on-site waste as long as the pile sits at least 25 feet from any dwelling, excludes meat, dairy, and most pet waste, and creates no odor or pests.

Key details: Setback from dwellings: 25 feet minimum. Source material: must be generated on-site. Banned inputs: meat, dairy, human/most pet waste. Allowed exception: rabbit and lawful chicken waste. Odor rule: not detectable off property.

Composting that breaches these limits is treated as a nuisance under Chapter 18: the town issues a notice of violation, and an uncorrected violation draws a $250 civil penalty plus $250 for each additional day.

Tree Trimming

Cary requires overhanging vegetation above streets, sidewalks and greenways to keep minimum clearance, from eight feet over sidewalks up to sixteen feet over designated thoroughfare streets.

Key details: Sidewalk/greenway clearance: 8 feet minimum. Other right-of-way clearance: 14 feet minimum. Thoroughfare street clearance: 16 feet minimum. Lateral clearance: 6 inches from pavement edge. Civil penalty: $250 plus $250/day.

Cary issues a written notice of violation with a deadline to trim. If the owner doesn't comply, the town may abate the encroachment itself and bill the cost, plus a $250 civil penalty and $250 for each additional day of noncompliance.

Native Plants

The Town of Cary exempts intentionally planted landscaped areas and heavily wooded lots from its 8-inch vegetation height cap, letting Wake and Chatham County residents keep native or naturalized plantings instead of mowed turf.

Key details: General height cap: 8 inches. Exempt: landscaped areas: non-grass, intentionally planted. Exempt: heavily wooded lots: too dense to mow. Must not encroach: ROW or neighboring lots. Enforced by: Town Manager, Chapter 18.

Failure to abate a cited nuisance can bring a $250 civil penalty plus an additional $250 for each day it remains unabated, collectible as a civil debt; there is no criminal penalty.

If you are coming from a city with tighter rules, you will find Cary gives residents more flexibility on native plants.

Tree Removal & Heritage Trees

Cary's Land Development Ordinance requires builders to fence off and protect existing trees marked for preservation before grading begins, with signage warning workers to stay out of the protected zone.

Key details: Fence type: orange polyethylene laminar. Min fence height: 4 feet. Sign spacing: every 300 linear ft. Base disturbance fine: $2,000.

Disturbing a fenced tree protection area without authorization triggers a $2,000 base fine under LDO § 11.5.2(B)(2)(b), plus $4 per square foot of area affected, on top of required replanting.

Water Restrictions

The Town of Cary limits outdoor irrigation from its water system to alternate days assigned by street address, with hand-held watering exempt.

Key details: Restriction: Irrigation on assigned alternate days only. Exempt: Hand-held hoses, drip irrigation, cans. Enforcement: Utilities director, police, or designee. Penalty trigger: Civil penalty after second notice. Effective through: Local ord. 2024-Code-04 (12-12-2024).

Civil penalty per the town fee schedule after a second notice; each day of violation is separately citable; violation is also a misdemeanor and can trigger service suspension.

Weed Ordinances

The Town of Cary bars any responsible person from letting vegetation grow past eight inches near streets, sidewalks, or buildings, with exceptions carved out for heavily wooded lots and defined landscaped areas.

Key details: Height limit: 8 inches. Who's liable: Owner, lessee, occupant, or agent. Key exemption: Heavily wooded lots, landscaped areas. Distance exemption: 50-100+ ft from street/dwelling. Criminal penalty: None: civil only.

The Town Manager or a designee can issue a notice of violation, and a responsible person who fails to abate may face a civil penalty, town abatement with the cost billed as a lien on the property, or chronic-violator status after three notices in a year: violations carry no criminal penalty.

Rainwater Harvesting

The Town of Cary's alternate-day watering rule for landscape irrigation applies only to potable town water, so harvested rainwater is unrestricted for lawn or garden use.

Key details: Rainwater use: Not day-restricted. Potable water rule: Alternate-day only. Also exempt: Well, pond, reclaimed water. Also exempt: Hand-held watering methods.

There is no violation for using harvested rainwater on any day; violations under this section attach only to irrigating with potable town water outside the assigned alternate day.

Cary is more permissive than most cities when it comes to rainwater harvesting. That said, there are still limits.

The Bottom Line

Compared to many U.S. cities, Cary gives residents more room on landscaping rules. 2 of the 7 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

These rules come from Cary's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
