Allegheny County municipalities enforce weed and noxious-vegetation ordinances through IPMC property maintenance code. PA Noxious Weed Law (3 P.S. Sections 255.1-255.8) lists regulated species including Japanese knotweed and giant hogweed that landowners must control.
The IPMC adopted under PA UCC requires property to be free of weeds and plant growth exceeding local height limits (typically 6-10 inches). PA Noxious Weed Law designates species such as Canada thistle, Johnson grass, giant hogweed, Japanese knotweed, Tree of Heaven, and spotted lanternfly host plants as regulated. PA Department of Agriculture can order abatement, though enforcement is generally complaint-driven. Allegheny County municipalities typically handle abatement by issuing a notice, mowing if the owner fails to act, and adding cost to the tax bill as a lien.
Municipal fines $25-$500 per offense plus abatement cost liens. PA Department of Agriculture noxious weed orders: civil penalties up to $300 per day.
