Summary

Harrison County does not set a general lawn-height limit, but any landscaping installed to satisfy the Unified Development Code's buffer, parking-lot or frontage requirements must be kept weed- and litter-free year-round.

These county ordinances apply to unincorporated areas of Harrison County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Ongoing maintenance of all landscaping is the responsibility of the property owner(s). The owner, property manager, tenant and their agent, if any, shall be jointly responsible for the maintenance of all required landscaping. All required landscaping shall be maintained in a healthy and growing condition as is appropriate for the current season. This shall include mowing, edging, pruning, fertilizing, watering, weeding, and other such activities common to the maintenance of landscaping. Landscaped areas shall be kept free of trash, litter, weeds and other such material or plants not a part of the landscaping.

Full Breakdown

Unincorporated Harrison County has no county-wide grass-height nuisance ordinance in the materials on file; instead, the weed-control obligation that does exist is tied to landscaping the county itself required a developer to install. 09(c), 'Site Improvements, Landscape Installation and Maintenance,' places ongoing maintenance of all required landscaping on the property owner, property manager, tenant and their agent jointly. The section requires that landscaping be kept 'in a healthy and growing condition as is appropriate for the current season,' explicitly listing mowing, edging, pruning, fertilizing, watering and weeding among the covered activities, and states that landscaped areas must be kept free of trash, litter, weeds and other material or plants that are not part of the approved landscaping.

10): in short, any planting a site was required to install to win zoning approval, not lawns generally. Dead plant material must be replaced with similar variety and size within 30 days, or on a longer schedule if the Administrator allows more time because of weather. Because the rule is a landscaping-maintenance condition of development approval rather than a freestanding weed-nuisance code, a lot with no required landscaping is not independently regulated here for grass height.

Violations & Fines

Non-compliance with required landscaping maintenance is a code violation the Zoning Officer can pursue under UDC § 1409: written notice, a Cease and Desist Order, or referral for injunctive relief. A knowing and willful violation is a misdemeanor under § 1409.03, carrying a fine of up to $100.00 plus court costs, with continuing non-compliance treated as a new offense each day.

Frequently Asked Questions

Does Harrison County have a maximum grass height for yards?
Not a general one on file. The county's landscaping-maintenance rule at UDC § 828.09(c) requires required landscape areas to be kept weed-free, but there is no separate county-wide inches-tall limit for ordinary lawns outside that required landscaping.
What landscaping does the weed-free rule apply to?
It applies to landscaping the UDC made a condition of development, such as parking-lot perimeter buffers, interior parking islands, foundation planting zones, and the three trees required on every single-family lot, per §§ 828.06 through 828.10.
Who is responsible for keeping required landscaping weed-free?
Section 828.09(c) makes the property owner, property manager, tenant and their agent jointly responsible for mowing, weeding and otherwise maintaining required landscaping in a healthy, growing condition appropriate to the season.
What happens if required landscaping is neglected?
The Zoning Officer can issue written notice or a Cease and Desist Order under § 1409, and a knowing, willful violation is a misdemeanor under § 1409.03 punishable by a fine of up to $100.00 per day the violation continues.
