Does Libertyville, Illinois have zoning, and what does it mean for lot size and setbacks?

Yes. The Village of Libertyville administers its own zoning ordinance, with R-1 to R-8 residential districts1. Lake County's zoning rules apply only to unincorporated land, so county zoning does not govern a lot inside Libertyville8.

The district decides the numbers. In the R-2 Single-Family Residential District the minimum lot is 40,000 square feet and 150 feet wide4. In R-3 the minimum lot is 20,000 square feet9. R-2 requires a front yard of 50 feet, an interior side yard of 20 feet and a rear yard of 60 feet; R-3 requires 40 feet in front, 20 feet at the side and 50 feet at the rear5.

Lot coverage is capped at 30 percent for an interior single-family lot in R-2 and 35 percent in R-310. A principal structure in R-2 may not exceed 2.5 stories or 37 feet11. Ribbon driveways are not permitted in R-212. We could not confirm minimum dwelling size, accessory dwelling rules or tiny-home rules; the Planning Division at (847) 918-2028 can answer them for a specific parcel13.

Do you need a building permit in Libertyville, and who issues it?

Yes. The Village of Libertyville's Building Division issues building permits inside village limits, and the village states that permits are required for any building, electric, plumbing, heating, and air conditioning work2. A permit may also be needed for tree removal2. Lake County Planning, Building and Development issues building permits only for unincorporated Lake County, so a Libertyville address does not go to the county counter14.

Building permit fees are based on the cost of construction, and a cash bond of $500 to $5,000 may be required2. We could not confirm the fee schedule, inspection steps or a certificate of occupancy rule for Libertyville; ask the Building Division. The State of Illinois does not issue permits for privately funded homes and leaves them to the local government, so the village is the office to ask15.

How do septic permits and wells work inside Libertyville?

Septic permits are not a village function. Where a property is not served by public sewer, the Lake County Health Department regulates treatment and dispersal of sewage from septic systems16. The county's septic permit rule covers incorporated and unincorporated Lake County where public sewers do not exist3. The process starts with a soil evaluation by a licensed soil classifier and a design by a licensed designer or engineer, and a licensed septic contractor then applies for the construction permit, which is valid for 120 days3. No part of the system may be backfilled until the health department inspects and approves it17.

We could not confirm whether a specific Libertyville lot is on public sewer; ask the Building Division before assuming either way2. New private wells need a permit from the Lake County Water Well Program in both incorporated and unincorporated areas6.

Can you live in an RV or camp on your land in Libertyville?

We could not confirm any Libertyville rule for living in an RV, trailer or tiny home on private land, so ask the Planning Division before buying or parking one13. The one camping rule we verified covers public property: camping in village parks requires a permit from the village administrator, valid for not more than 24 hours, and is allowed only in Butler Lake Park and Adler Park7. A violation is a misdemeanor with a fine of $250 to $750, up to six months in jail, or both7.

Illinois's campground licensing law applies to licensed campgrounds, not to living on your own lot, so it does not answer the question18. Lake County's tent and camping limits apply only in unincorporated Lake County19.

Building a home in Libertyville: the steps, in order

  1. Confirm the zoning district and its lot size, setbacks and coverage limits with the Planning Division, which also checks lot coverage using your plat of survey13.
  2. Find out whether the lot has public sewer. If it does not, start with a soil evaluation and septic design for the Lake County Health Department3.
  3. If you need a private well, get a permit from the Lake County Water Well Program before drilling6.
  4. Submit plans to the Building Division for plan review and a construction permit2.
  5. Expect inspections during construction, and a septic system must be inspected before it is backfilled17.

For a new house the village's residential permit checklist lists a plat of survey, architectural and engineering plans, and energy calculations, so ask the Building Division for the full list2.

What stays with Lake County, and what to check before you buy in Libertyville

Land outside village limits follows Lake County's rules instead, which are different; see the Lake County page for unincorporated land8. Inside Libertyville, septic and well permits stay with the county health department, and driveways or work in the right-of-way of a state route need a permit from the Illinois Department of Transportation20. Floodplain and watershed development permits can apply in Lake County; ask the Building Division whether a lot needs one21.

Countywide figures give context: Lake County's typical home value is about $400,96422, and the effective property tax rate is 2.7%23.

Watch-outs

  • Construction hours inside Libertyville limit work to after 7:00 am Monday through Friday, after 8:00 am on Saturday and after 12:00 noon on Sunday, with work ending by 6:00 pm daily2.
  • We could not confirm whether a given Libertyville lot is on public sewer, which decides whether the Lake County Health Department's septic rules apply; ask the Building Division2.
  • Lake County's rules for unincorporated land, including short-term rental limits and its building codes, do not apply inside Libertyville village limits8.
