Do you need a building permit in the Village of Park Forest, IL?

The Village of Park Forest requires building permits for the work listed on its permit page, whether a homeowner or contractor performs the work; separate improvements may need separate building permits.1 Park Forest home-improvement permits cover roofing, siding, soffit, gutters, concrete driveway work and asphalt driveway or parking-lot paving.1 Work valued at $250 or less still needs a building permit but carries no traditional permit fee; listed home-improvement permits cost $60, and electrical or plumbing inspection fees may also apply.8 Park Forest has adopted building codes with Village amendments, so ask the Building Department which code requirements apply to your project before preparing drawings.9

Who handles building permits and zoning in the Village of Park Forest?

Park Forest’s Community Development Department oversees building and zoning services and planning; its Building and Code Enforcement divisions handle new construction and building-permit activity within the Village.10 Submit construction drawings, the scope of work and contracts with the building-permit application.10 Park Forest accepts building-permit documents at the Building Department counter, through the Village Hall drop box, or by FedEx, UPS or US Mail.10 Septic review is a separate health-department responsibility: Cook County Department of Public Health reviews private sewage systems in the Cook County portion, while Will County Health Department handles private sewage services in the Will County portion.34

Does the Village of Park Forest have zoning, lot-size and setback rules?

The Village of Park Forest administers its own zoning and Unified Development Ordinance, with requirements that depend on the parcel’s district.2 In Park Forest’s R-1 Single-Family Residence District, the minimum lot area is 7,200 square feet and minimum width is 60 feet; maximum impervious coverage is 40%.1112 In the R-2 Single-Family Estate Residence District, the minimum lot area is 10,000 square feet and minimum width is 100 feet, with maximum impervious coverage of 35%.1314 Park Forest’s R-4 Urban Residential District instead requires front and corner-side setbacks between 5 and 20 feet, an interior-side setback of at least 5 feet and rear setback of at least 10 feet.15 Ask Community Development to confirm the district and applicable standards for your parcel before designing a house or driveway.10

How do septic permits and private wells work inside Park Forest?

For the Cook County portion of Park Forest, Cook County Department of Public Health reviews and approves private sewage disposal systems; a well or septic evaluation is typically needed when buying or selling a home with those systems.3 For the Will County portion of Park Forest, contact Will County Health Department’s Private Sewage Program about septic installation and issued septic permits.4 Illinois requires private sewage plan approval from the applicable authority before construction, and notification at least 48 hours before system construction, installation, repair or modification begins.16 Illinois also requires a permit from IDPH or an approved local health department before constructing, deepening, modifying or sealing a private well; ask the relevant county health department which office will accept the application.7

Building a home in the Village of Park Forest: what are the steps?

  1. Ask Park Forest Community Development to confirm the parcel’s zoning district and proposed residential use before drawing the site plan.210
  2. Confirm water and sewer service with the Village; we could not confirm a general mandatory utility-connection rule, and a proposed septic system needs the appropriate county health department’s review.1034
  3. Submit the Village building-permit application with construction drawings, scope of work and contracts.10
  4. If performing the work yourself, use Park Forest’s homeowner-waiver process: a building permit is still required, unpaid family or friends may help, and compensated workers must be Village-licensed contractors.5
  5. Ask the Building Department about floodplain protection before placing the home; residential lowest floors, including basements, must be elevated to the flood-protection elevation in regulated floodplains.17

For land outside village limits, consult the Cook County guide; Cook County’s building-permit requirement applies to unincorporated land.18

Watch-outs

  • A Park Forest homeowner waiver does not waive the building permit, and paid helpers must be Village-licensed contractors.5
  • Park Forest rental homes need a change-of-occupancy inspection whenever rental occupants change.19
  • We could not confirm tiny-home occupancy, accessory-dwelling or mandatory utility-connection rules; ask Park Forest Community Development before purchasing for those plans.10
