Summary

In unincorporated Lake County, a car, van, or truck parked between the house and the street in a residential zone must sit on an improved pad or driveway, never on grass. The pad is capped at 400 square feet unless it qualifies as a driveway.

City-specific rules exist: Waukegan has its own driveway rules rules that differ from Lake County's county-level regulations. If you live in Waukegan, check the city-specific page instead.

However, the parking of any car, van, or truck may occur between the principal structure and an improved street in residential zoning districts only on an improved pad not to exceed 400 square feet or on an improved driveway (in both cases either gravel, paved, or otherwise improved with hardscape). In no event shall these personal vehicles be allowed to park on grass or other unimproved surface between the principal structure and an improved street. This provision shall not apply to nonresidential uses permitted in residential zones.

Full Breakdown

165(F)(2) sets the rule for where residents may park personal vehicles in front of their homes. Parking a car, van, or truck between the principal structure and an improved street is allowed only on an improved pad not exceeding 400 square feet, or on an improved driveway, and in both cases the surface must be gravel, paved, or otherwise improved with hardscape. The code is explicit that these vehicles may never be parked on grass or any other unimproved surface in that front-yard zone. Planning, Building and Development enforces the standard as part of the county's off-street parking regulations, and the rule carves out an exception for nonresidential uses that are permitted within residential zoning districts, which are not bound by this front-yard surfacing requirement.

An accompanying commentary note in the code clarifies the intent: the section is not meant to stop occasional or short-term parking on grass for special events such as family gatherings or parties, so a one-time gathering that spills extra cars onto the lawn is treated differently from routine, day-to-day parking on unimproved ground. 165, also requires that parking areas be kept dust-free and that nonresidential lots between the street and the building be paved, reflecting the county's consistent preference for hard surfaces over bare ground wherever vehicles regularly sit.

Because the rule sits inside the zoning-based off-street parking article rather than a stand-alone nuisance chapter, violations are handled through the county's zoning enforcement process rather than as a separate parking ticket.

Violations & Fines

Zoning enforcement staff in the Planning, Building and Development Department investigate reports of vehicles parked on grass in front yards and can require the surface brought into compliance with an improved pad or driveway. Continued noncompliance is treated as a zoning violation under the off-street parking article, which can lead to a citation and an order to remove the vehicle from the unimproved area until a conforming pad or driveway is installed.

Frequently Asked Questions

Can I park my truck on the grass in front of my house in unincorporated Lake County?
No. Section 151.165(F)(2) bars parking a car, van, or truck on grass or any other unimproved surface between your house and the street in residential zoning districts. The vehicle must sit on an improved pad up to 400 square feet or on an improved driveway.
How big can a front-yard parking pad be?
An improved parking pad in the front-yard area between the house and the street cannot exceed 400 square feet under § 151.165(F)(2). A driveway itself is not subject to that 400-square-foot cap, only a separate improved pad is.
Am I allowed to let guests park on my lawn for a party?
Yes. The county's commentary to § 151.165(F)(2) states the rule is not meant to prohibit occasional or short-term grass parking for special events like family functions and parties, distinguishing that from routine daily parking.
