Summary

In the City of Plymouth, turf grass on any property, developed or vacant, cannot exceed eight inches, and noxious weeds are prohibited outright under City Code §§ 807.03 and 807.04. A property owner who ignores the City's mailed or posted notice can be cited under § 807.06.

807.03. - Vegetation Length. Except where native landscapes are allowed under Section 811 of this Chapter and except on property zoned FRD (future restricted development), the length of turf grass may not exceed eight inches. ... 807.04. - Noxious Weeds. Noxious weeds are prohibited. Property owners are responsible for eradication, removal, trimming, and/or maintenance of noxious weeds and tall turf grass on their property, as defined in this Section. ... 807.06. - Corrective Action by City. If the owner of any property fails to comply with a notice, as provided for by Subd. 807.05, the City may issue the property owner a citation.

Full Breakdown

Section 807 of the Plymouth City Code, Vegetation Management, applies to every lot or parcel in the City, including vacant and unimproved land, plus the boulevard and any abutting trail or sidewalk outlot the owner's property touches. 03 caps turf grass length at eight inches, except on land the Code allows to stay as native landscape under § 811 or land zoned FRD, future restricted development, a designation the City uses for land still awaiting development. 04 separately bans Noxious Weeds, defined by cross-reference to the plants the state Commissioner of Agriculture designates Prohibited Eradicate or Prohibited Control under Minn.

77, Subd. 8, and makes the property owner responsible for eradicating, removing, trimming, or otherwise maintaining both noxious weeds and tall turf grass. 05 requires the City to notify the owner by first-class letter or posted notice describing the violation, the fix, and a deadline. 06 lets the City issue a citation. 07 offers a narrow hardship exemption, reviewed by the Park and Recreation Director and appealable to the Council within ten days, limited to genuine safety problems such as slopes steeper than 3-to-1 or standing water, not simple neglect of an empty lot.

Violations & Fines

Letting turf grass on any lot, including a vacant one, grow past eight inches, or letting noxious weeds spread, violates §§ 807.03-807.04 once the City's notice deadline under § 807.05 passes uncorrected. The City may then issue a citation under § 807.06; absent a hardship exemption granted under § 807.07, the general Code penalty of up to $700.00 and 90 days in jail applies.

Frequently Asked Questions

Does Plymouth's weed ordinance apply to a vacant lot I own?
Yes. Section 807.02 defines Property as any lot or parcel plus its abutting boulevard, with no exception for vacant or undeveloped land, so the eight-inch turf limit and noxious weed ban in §§ 807.03-807.04 apply.
How does the City notify me before citing me for tall weeds?
Under § 807.05, the City sends a first-class letter to the property owner or posts a notice on the property describing the violation, how to fix it, and a deadline before any citation issues under § 807.06.
Can I get out of mowing a steep or wet vacant lot in Plymouth?
Only through the § 807.07 hardship process: apply in writing to the Park and Recreation Director showing a slope steeper than 3-to-1 or standing water makes safe mowing infeasible, with a right to appeal a denial to the Council within ten days.
