Oak Park FAQ
How tall can my grass be in Oak Park?
Grass and vegetation on residential property may not exceed 8 inches in height. This applies to all yard areas and the parkway strip between the sidewalk and curb.
What happens if I do not mow my lawn in Oak Park?
You will receive a written notice with 5 to 7 days to mow. If you do not comply, the Village will hire a contractor to mow your property and bill you $200 to $400 or more, which becomes a lien on your property.
Can I have a natural or prairie-style yard in Oak Park?
Yes. Naturalized or prairie-style landscaping is permitted as an alternative to traditional lawns, but it must be properly maintained, clearly intentional in design, and free of noxious weeds. You may need to register the garden with the Village.
Tinley Park FAQ
How tall can my grass get in Tinley Park?
Grass and weeds must be kept below 8 inches. Taller growth triggers code enforcement notices and, if not corrected, village-contracted mowing billed to the owner.
What if I have a native plant garden?
Documented managed native plant gardens and pollinator habitats may qualify for exemption from grass height rules. Keep design plans and maintenance records to support the exemption.
What if my lawn care company is delayed?
Contact Tinley Park Community Development to request a short extension if you receive a notice. Proactive communication often avoids village mowing charges.
