(E) Managed natural landscape. As an exception to section (D), an owner, authorized agent, or authorized occupant of any privately-owned lands or premises may... install and maintain a managed natural landscape such as native plantings, meadow vegetation, prairie, or rain garden, as long as the following requirements are met: (1) At all times the managed landscape must remain in compliance with Chapter 97... In addition, the managed landscape must be set back from property lines by at least five feet.

Full Breakdown

Property Maintenance Code § 156.052(D) caps plant growth at 10 inches, but subsection (E) creates a managed natural landscape exception. Owners may plant native species, meadow vegetation, prairie, or rain gardens if the bed sits back at least 5 feet from property lines (waived next to a matching landscape, wetland, pond, lake, stream, or a 4-foot opaque fence), is mowed or cut back at least once a year, is clearly edged or fenced, stays out of the public right-of-way, carries a posted sign noting native plants are established, and excludes noxious weeds under KRS 176.051. Unattended turf-grass lawns don't qualify.

Violations & Fines

Landscapes that miss the setback, edging, annual cutback, or signage requirements are treated as ordinary excess weed growth and cited under § 156.052(D)/§ 156.999, which authorizes Code Official abatement orders and civil penalties.

Frequently Asked Questions

Can I let a native garden grow taller than 10 inches in Louisville?
Yes. Louisville Metro's § 156.052(E) managed natural landscape exception allows native plantings, meadow vegetation, prairie, or rain gardens above the normal 10-inch weed cap if you meet the setback, edging, mowing, and sign requirements.
Do I need a permit for a managed natural landscape?
No permit is required, but you must post a sign, keep a 5-foot setback (or qualifying buffer/fence), edge the bed, and cut it back at least annually.
Does this apply everywhere in Jefferson County?
It applies within Louisville Metro's Property Maintenance Code jurisdiction. Home rule cities inside the county, like Anchorage or St. Matthews, may enforce their own separate rules.
