How Lexington Handles Landscaping Rules: A Practical Guide

Lexington maintains 115 local ordinances across all categories, and 5 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Lexington falls on the strict-to-permissive spectrum compared to other cities.

Weed Ordinances

Lexington-Fayette makes it unlawful for any owner to let weeds or grass grow past 10 inches anywhere on a property, including the strip between the sidewalk and the street, and repeat violators within two years face escalating civil fines up to $1,500 on top of the standard $100-to-$2,500 nuisance fine.

Key details: Height limit: 10 inches (weeds and grass, Sec. 12-2). Fine: $100–$2,500 per offense, per day. Repeat-offender civil fine: $100–$1,500 within 24 months. Banned outright: USDA-listed noxious weeds regardless of height. Exempt: agricultural-zoned land, native/pollinator naturalization.

Overgrown weeds or grass past 10 inches draws a fine of $100 to $2,500 per offense under Section 12-5, with each day of continued violation a separate offense. Owners cited more than once on the same property within 24 months face an added civil-fine schedule, $100 for a second citation, $250 for a third, $500 for a fourth, $1,000 for a fifth and $1,500 for a sixth or later, and unpaid abatement costs become a lien on the property.

Native Plants

Lexington-Fayette's nuisance code carves out an explicit exemption for native, naturalized landscaping from its weed and grass height rule. Under Sec. 12-2, plantings intended for food, fiber, pollinator habitat, erosion control, stormwater management or soil health are not treated as a nuisance, provided the property owner keeps managing the site rather than letting it go wild.

Key details: Governing section: Code of Ordinances § 12-2. Qualifying purposes: Food, fiber, pollinators, erosion, stormwater, soil. Disqualifier: Vegetation abandonment (no site management). Species limit: No KY Exotic Plant Pest Council level-one species. Enforcement body: Code enforcement board (KRS 65.8801–65.8839).

There's no permit or registration to lose here, but a property that claims the exemption while showing no site preparation, planting plan or upkeep can still be cited as an ordinary weed nuisance under Sec. 12-2, exposing the owner to code enforcement board fines of $100 to $2,500 per offense, with each day of continued violation counted as a separate offense under Sec. 12-5.

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

Composting

Lexington-Fayette regulates backyard compost piles through its general nuisance code. Sec. 12-2 requires every compost pile on a property to sit in a clearly definable area, stay out of ordinary public view, and avoid becoming a magnet for vermin, insects or animals, or a nuisance, health hazard, safety issue or fire concern in its own right.

Key details: Governing section: Code of Ordinances § 12-2. Placement rule: Clearly definable area, out of public view. Pest rule: Must not attract vermin, insects or animals. Permit required: None specified in the code. Fine: $100–$2,500 per offense.

A compost pile that draws vermin, spills into public view, or otherwise becomes a nuisance triggers the same notice-and-citation track as any other Sec. 12-2 violation: a non-appealable notice of violation demanding abatement first, then a citation carrying a civil fine of $100 to $2,500 per offense under Sec. 12-5 if the problem isn't fixed, with each additional day counted separately.

Tree Trimming

Street trees in Lexington-Fayette's right-of-way must be kept clear of sidewalks and streets, minimum overhead clearance is 7 feet over sidewalks, 12 feet over ordinary streets, and 14 feet over truck routes, and owners bear the maintenance duty, while severe 'topping' cuts are separately banned.

Key details: Clearance over sidewalks: 7 feet minimum. Clearance over streets: 12 feet minimum. Clearance over truck routes: 14 feet minimum. Topping ban: Cuts to stubs over 3 in. dia. in crown, unlawful. Sign-visibility pruning cap: Under 25% of crown.

Failing to maintain clearance, or over-pruning/topping a street tree, is enforced as a civil citation under § 17B-12, issued by officers authorized under § 14-10 and referred to the infrastructure hearing board. A notice of violation with at least a 24-hour cure period typically precedes the first citation. Each day a clearance or topping violation continues is a separate offense, up to a maximum civil fine of $2,500 per violation, with the urban county government able to abate the hazard itself and bill the owner, including a $150 administrative fee.

Tree Removal & Heritage Trees

No one may remove a street tree over 3 inches in diameter from Lexington-Fayette's right-of-way without a permit from the division of environmental services. Permits issue routinely for dead or dying trees but only in special circumstances for a live one, and the division can also order removal itself.

Key details: Permit trigger: Tree diameter over 3 inches, measured at 4.5 ft. Permit issuer: Division of environmental services. As-of-right ground: Tree is dead or dying. Live-tree removal: Only special circumstances (safety, disease, replacement). Max civil fine: $2,500 per day (§ 17B-12).

Removal without a permit, or outside the terms of one, is enforced under § 17B-12 by civil citation from officers authorized under § 14-10, referred to the infrastructure hearing board under Chapter 2B. A notice of violation with a minimum 24-hour cure period normally comes first unless the harm is irreparable or a serious safety threat. The maximum civil fine is $2,500 per violation, with each continuing day a separate offense, and the urban county can additionally abate the condition itself and bill the responsible party, including a $150 administrative fee, with lien rights under KRS 65.8835.

Compared to other cities, Lexington takes a harder line on tree removal & heritage trees. The enforcement and penalty structure reflects that.

The Bottom Line

Lexington's landscaping rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Lexington is broadly strict or permissive.
