Peoria, AZ Landscaping Rules: Weed Ordinances (2026)

Section 17-3(l) of the Peoria City Code prohibits any owner, lessee, or person in control of a premises from allowing weeds or grass to grow past six inches, or from letting vegetation create a danger to public health or safety. Section 17-2(mm) defines 'weeds' for a residential lot of one acre or less as any uncultivated shrub or vegetation over six inches, lawn grass over six inches, or any dead vegetation. S. Section 3-201, regardless of whether the person responsible considers the growth desirable. Section 17-3(l) lets owners of lots over one acre use a firebreak between the adjacent property and the subject property instead of maintaining the entire parcel at six inches, with the firebreak itself defined in Section 17-2(m) at ten feet from the line next to a vacant lot or fifteen feet where a structure sits on the parcel.

Wildflowers are carved out of the height limit entirely, but that exemption ends the moment the wildflower growth turns dead, dormant, or dry enough to become a fire hazard. Violations run through the standard Chapter 17 enforcement track: a Class 1 misdemeanor under Section 17-51(d), a separate offense for each day the overgrowth continues under Section 17-51(e), and a 30-day court-ordered abatement window under Section 17-53 before the City can mow the lot itself and bill the owner.
