Evanston FAQ
How tall can my grass be before I get a violation?
Grass and weeds must be kept below 10 inches. Once the city issues a notice, you have 7 days to mow. If you do not comply, the city will mow your property and bill you a minimum of $150 to $300.
Can I have a natural prairie garden instead of a lawn?
Yes, but natural landscaping must appear intentional with defined borders and maintained paths. You may need to register the garden with the city to avoid code enforcement action. It cannot simply look like an unmowed lawn.
What about vacant lots?
Vacant lots are held to the same 10-inch standard. The city proactively inspects vacant properties during growing season and will mow at the owner's expense if the property is not maintained.

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.
