Summary
Louisville Metro caps weeds and plant growth at 10 inches on every property, vacant or occupied, under Chapter 156 of the Property Maintenance Code. Owners of unmaintained lots face code enforcement action and a civil penalty for violations.
All premises shall be maintained free from weeds or plant growth in excess of ten inches. All noxious weeds shall be prohibited. Weeds shall be defined as all grasses, annual plants and vegetation other than trees or shrubs provided, however, this term shall not include cultivated flowers and gardens.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-47: Supplement contains: Local legislation current through Ordinances passed by the Council and approved by the Mayor as of July 1, 2026).
Full Breakdown
Louisville Metro's Property Maintenance Code (LMCO Chapter 156) makes every property owner responsible for keeping weeds and plant growth under 10 inches, and bans noxious weeds outright: the code defines 'weeds' as grasses, annual plants and other vegetation, excluding trees, shrubs, cultivated flowers and gardens (§ 156.052(D)). A separate provision requires that vacant structures and vacant land be kept clean, safe, secure and sanitary so they don't create a blighting problem (§ 156.050(C)). Owners who want a low-mow yard can register a 'managed natural landscape' of native or meadow plantings if they set it back from the property line, edge it, post a sign, and mow it at least once a year (§ 156.052(E)).
Violations & Fines
Violations are civil offenses under LMCO § 156.999(B): the Code Official can cite the owner per Metro's penalty schedule, order abatement, and each day the growth continues past 10 inches is a separate offense.
