Zoning, building permits and land rules in Hanover Park, Illinois

The Village of Hanover Park, Illinois sets its own zoning and requires a village building permit for nearly all construction work12. Permits and inspections run through the Inspectional Services Division of the village Fire Department3, and zoning relief goes through the village Planning & Zoning staff4. We could not confirm who issues septic permits inside the village; ask the DuPage County Health Department5.

Does Hanover Park have zoning, and what does it mean for lot size and setbacks?

Yes. The Village of Hanover Park, Illinois adopts and enforces its own zoning in Chapter 110 of the village code1, with residential districts R, R-1, R-2, R-3 and R-47. We did not review the business and industrial districts.

Dimensions depend on the district. In R-1, a single-family house needs an interior lot of at least 10,000 square feet or a corner lot of at least 12,000 square feet8. In R-2 the minimums are 7,735 and 9,000 square feet10. The semirural R district needs 40,000 square feet interior or 45,000 corner11.

In R-1, the front yard is at least 30 feet12. Buildings in R, R-1 and R-2 may not exceed 35 feet9. Lot coverage is capped at 35 percent in R-1 and R-213 and 20 percent in R14. On lots under 40,000 square feet or 150 feet wide, an R-1 lot gets one curb cut15.

We could not confirm village rules on RVs, tiny homes, accessory dwellings or minimum house size. Ask Planning & Zoning at 630-823-56004.

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

Yes, for almost any construction work. Hanover Park amended its 2021 residential code so that only minor items such as finish work and replacing exterior siding remain exempt2. Work without a permit pays double the permit fee, and a second violation within 12 months pays quadruple or a $200 minimum2.

The village enforces its residential code through the Inspectional Services Division of the Hanover Park Fire Department3. The division's page states that work may begin only after the building permit is issued6. Call 630-823-5860 before you start to learn the requirements for your project6.

If your project needs no zoning relief, the village reviews building permits for code compliance directly4. Illinois itself does not issue building permits for private construction; that falls to the local government16.

We could not confirm the village's permit fee schedule or a certificate-of-occupancy rule; ask Inspectional Services.

How do septic permits work in Hanover Park?

We could not confirm who issues septic permits inside Hanover Park village limits, so ask before you plan any septic system. The village sits partly in Cook County and partly in DuPage County, which affects which health department applies.

For DuPage County, the DuPage County Health Department runs the private sewage disposal program and directs applicants to its Plan Review staff at 630-221-70455. A new system there carries a permit and plan review fee of $68417. Illinois requires plan approval from the state or the local authority before construction of a new private sewage disposal system begins18.

We have not found a village rule on wells either. Statewide, a permit from the Illinois Department of Public Health or an approved local health department is required before building a new water well19.

Building a home in Hanover Park: the steps, in order

  1. Confirm the zoning district of your lot and its lot size, setbacks and height limits with Planning & Zoning at 630-823-56004.
  2. If you need a rezoning, variation, special use or subdivision, the village asks for a pre-application meeting and offers an optional concept plan review first4.
  3. Call Inspectional Services at 630-823-5860 for the permit requirements for your project, then apply for the building permit6.
  4. Start work only after the permit is issued6.
  5. Schedule each inspection by calling at least 24 hours ahead; a failed inspection costs $50.0020.
  6. Ask Inspectional Services about final inspection and any occupancy requirement, which we could not confirm.

What stays with DuPage County, and what should you check before buying in Hanover Park?

The county's building and zoning rules apply to unincorporated land only. Inside the village limits, the village handles building permits and zoning, not the county1. For land outside any city, see the DuPage County page.

Septic and well permits are the likely county piece: DuPage County Health Department Plan Review at 630-221-7045 handles them in DuPage County5. A new well permit application costs $376 there21.

Check the floodplain before you buy. Illinois requires a state permit for building in a regulated floodway22. County-level figures: DuPage County's effective property tax rate is 2.1%23, and its typical home value is about $449,18524.

Watch-outs

  • Hanover Park lies in both Cook and DuPage counties, so confirm which county your address is in before you call a county office5.
  • Doing work without a village building permit costs double the permit fee2.
  • We could not confirm village rules on RV storage or living, tiny homes or accessory dwellings; ask Planning & Zoning before you plan around them4.
  • Zoning rules above cover only the single-family residential districts we reviewed; business and industrial districts need a call to Planning & Zoning7.
