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

Yes. The Village of Glenwood adopts its own zoning ordinance for land inside the village1. Residence districts R1 through R4 are confirmed; the full district map was not reviewed5.

For a single-family detached home, the minimum lot area is 8,400 square feet in R1, 7,200 in R2, 6,000 in R3 and 7,200 in R49. The front or street-side yard is 30 feet in R1 and 20 feet in R2, R3 and R411. Residential height is capped at 35 feet in R1, R2 and R3 and 45 feet in R412. Detached accessory buildings in residence districts are limited to one story or 15 feet, whichever is lower12.

Ask the Building Department which district a parcel is in before you plan anything; these figures vary by district.

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

Building permits inside Glenwood come from the Village Building Department, listed under Inspectional Services on the village website, not from Cook County6. The village has adopted the 2015 International Residential Code with local amendments2.

New construction is subject to inspection, including a top-of-foundation plat sealed by an Illinois licensed surveyor, reviewed after the foundation walls are set and before further construction7. A certificate of occupancy requires an engineer-sealed plot plan showing the as-built top of foundation8.

We could not confirm the permit fee schedule, the step-by-step application process, or whether owner-builders have special treatment in the village. Call the Building Department to confirm6.

How do septic permits work inside Glenwood?

Septic approval is not a village function. The Cook County Department of Public Health reviews and approves private sewage disposal systems throughout Cook County, with exceptions only for Barrington Hills, Inverness, Palos Park and South Barrington, and Glenwood is not among them13. Illinois also requires plan approval for any new private sewage disposal system14.

We could not confirm whether a given Glenwood lot is served by village water and sewer or would need a septic system or well. The water and sewer connection rules were not located, so ask the Building Department and the Cook County Department of Public Health before you buy613. Buying or selling a home with a well or septic system typically triggers an evaluation13.

Can you live in an RV, trailer or tiny home in Glenwood?

No for RVs and trailers. Glenwood zoning states that travel trailers, camping trailers and mobile homes shall not be occupied for dwelling purposes3. In R1, R2 and R3 only one travel or camping trailer may be stored or parked per lot3. Temporary construction trailers are allowed with a permit from the village trustee in charge of judiciary and license3.

Tents are limited to small recreational tents on the same lot as a dwelling, in the buildable area or rear yard15. Trailers and mobile homes may not be permanently affixed to the ground as a principal building or accessory structure in any district16. Whether a HUD-code manufactured home on a permanent foundation is treated differently was not confirmed. We found no tiny-home provision, so call the Building Department before planning one.

Building a home in Glenwood: the steps, in order

  1. Confirm the parcel's zoning district and the lot, setback and height rules for it with the Village Building Department96.
  2. Check whether the parcel is in the special flood hazard area; the village flood ordinance covers new buildings valued over $1,000 or 70 square feet, and requires the lowest floor at or above the flood protection elevation10.
  3. Apply for a building permit with the Building Department; the home must meet the 2015 International Residential Code as amended by the village2.
  4. If the lot is not on village sewer, get Cook County Department of Public Health approval for the septic system13.
  5. Submit the surveyed top-of-foundation plat after the foundation walls are set and wait for review before building further7.
  6. Before final inspection, provide the engineer-sealed as-built plot plan to obtain a certificate of occupancy8.

What stays with Cook County, and what to check before you buy in Glenwood

Cook County's Department of Building and Zoning handles unincorporated areas only; it directs inquiries about properties in municipalities to the local building and zoning authority6. For land outside village limits, see the Cook County page.

Within the village, the county role is septic and well review through the Department of Public Health13. Illinois requires a state permit for work within the right-of-way of a state route, which matters for a driveway onto one17. Cook County's effective property tax rate is about 2%, with a median tax bill of about $6,053 a year1819. These are county-level figures.

Watch-outs

  • We could not confirm Glenwood's building permit fees, application process, driveway rules or water and sewer connection requirements; call the Village Building Department before you commit to a parcel6.
  • Glenwood prohibits living in trailers and mobile homes in every district, so an RV is not a place to stay while building3.
  • Septic and well approval comes from the Cook County Department of Public Health even inside the village13.
