Summary

In unincorporated Utah County, owners and occupants must control injurious and noxious weeds on their own property or face a written notice from the County Board of Health demanding removal, with the County empowered to do the work itself and bill the owner if the deadline is missed.

City-specific rules exist: Eagle Mountain, Orem, and Provo have their own weed ordinances rules that differ from Utah County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

It shall be unlawful for any person owning or occupying any real property in the County to fail to control the growth of injurious and noxious weeds on such property or to fail to remove from such property any such weeds or any refuse and any unsightly or deleterious objects of structures upon notice from the County as provided in this chapter.

Full Breakdown

020 makes it unlawful for anyone owning or occupying real property in the unincorporated county to fail to control the growth of injurious and noxious weeds, or to fail to remove weeds, refuse, or unsightly deleterious objects once the County has given notice. 100, the County Board of Health (or an employee the County Commission designates) investigates, identifies the owner through County Assessor records, and serves written notice, personally or by mail, giving no less than ten days to eradicate, destroy, or remove the weeds.

Once a property has been noticed once in a calendar year, no second notice is required to compel further removal that year. 110 lets the County hire help to do the removal itself, then mail an itemized statement of expenses with a demand for payment within twenty days. 110) turns unpaid weed-removal bills into a property lien collected with general property taxes if not paid within ninety days. 020. None of this reaches Provo, Orem, or the county's other incorporated cities, which enforce their own weed codes.

Violations & Fines

Failing to act on a weed notice within the ten-day (or Board-set) deadline lets the County enter the property, remove the weeds, and bill the owner; an unpaid bill can be collected by lawsuit under § 7.10.130 or, for noxious-weed cleanups under Chapter 7.11, becomes a lien against the property collected with property taxes if not paid within 90 days of the demand.

Frequently Asked Questions

Does Utah County set a maximum height for weeds or grass?
No inch or foot limit appears in the code. Section 7.10.020 simply bars failing to control injurious and noxious weeds once notified, and Chapter 7.11 lists specific noxious weed species rather than a height threshold.
What happens if I ignore the County's weed notice?
The County Board of Health can send crews to remove the weeds itself, then mail you an itemized bill due within 20 days under § 7.10.110. Unpaid bills can be sued for under § 7.10.130 or, for state-listed noxious weeds, turned into a property tax lien under § 7.11.110.
Does this apply inside Provo or Orem?
No. This chapter's enforcement reaches only unincorporated Utah County. Provo, Orem, and the county's other incorporated cities enforce their own separate weed and nuisance codes.
