Detroit FAQ
What counts as a noxious weed in Detroit?
Locally, Sec. 8-15-35(a) treats non-cultivated plant growth over 8 inches as a violation. Michigan Act 359 names noxious weeds including Canada thistle, ragweed, wild carrot, bindweed, dodders, mustards, hoary alyssum, sowthistle, poison ivy, and poison sumac.
Will Detroit fine me for a pollinator garden?
No, as long as it's maintained. Section 8-15-35(a) excludes plant growth in areas where flowers and gardens are cultivated. Unmanaged, neglected plantings can still draw a notice.
What happens if I ignore a weed notice?
BSEED can dispatch contractor mowing crews to abate the property and bill the owner for mowing plus administrative fees. Unpaid charges become a lien and may be added to the tax roll.
