Does North Barrington, IL have zoning, and what does it mean for lot size and RVs?
Yes. The Village of North Barrington adopts and administers its own zoning ordinance, Title 10 of the village code, and divides all land within village limits into districts1. The districts include R-1 (five acre residential), R-2 (two acre residential) and R-3 (40,000 square foot residential), plus golf course, office, business, planned and equestrian estate districts9. District boundaries are on the village zoning map, so confirm a parcel's district with the Building Department before you buy.
In the R-1 district, a single-family lot needs at least 5 acres, 200 contiguous feet at the front lot line and an average width of at least 300 feet4. Buildings may not exceed 3 stories or 35 feet6.
For RVs, the R-1 district excludes trailers from single-family residences, and an owner's travel trailer or motorhome may be parked on the premises but not otherwise used or occupied7. Rules for other districts, tiny homes and temporary camping were not confirmed; ask the Building Department. The village also reports a zoning code update in draft, with final approval expected in early 2027, so the current code governs until then1.
Do you need a building permit in North Barrington, and who issues it?
Yes. Inside the Village of North Barrington, the village Building Department coordinates plan review, permit issuance and on-site inspection of building projects210. Inspection services are performed by B&F Technical Services for the village11. Land divisions and subdivisions are also regulated by the village12.
A certificate of occupancy must be secured before a building is occupied by persons sleeping or cooking in it. The Building and Zoning Officer issues it after inspection, and may allow a temporary occupancy permit of up to 6 months5.
Illinois itself does not issue building permits for privately funded construction; any permit requirement comes from the local government13. We could not confirm the village's permit fees, the exact projects that trigger a permit, or the building codes it applies, so call the village Building Department before you plan a project10.
How do septic permits work inside North Barrington?
Septic permits are a county matter, not a village one. The Lake County Health Department regulates treatment and dispersal of sewage from septic systems on properties not served by a public sewer1415. Its permit process covers incorporated and unincorporated Lake County where public sewers do not exist3.
The steps: a licensed soil classifier completes a soil evaluation, a licensed designer or engineer designs the system, the plans go to the Health Department, and a licensed septic contractor applies for the construction permit, which is valid for 120 days3. The Health Department inspects construction, and no portion of the system may be backfilled until it is inspected and approved16.
We could not confirm whether a specific North Barrington address is on public sewer or must use a septic system, so ask the village Building Department and the Health Department. New private wells also need a Lake County Health Department permit, in incorporated and unincorporated areas alike8.
Building a home in North Barrington: the steps, in order
- Confirm the parcel's zoning district on the village zoning map with the Building Department, and check the lot against the district's minimum size, for example 5 acres in R-1410.
- Ask the Lake County Health Department whether the lot needs a septic system and a well, and start the soil evaluation and system design38.
- Submit the building permit application, linked from the village Building Department page, for plan review17.
- Build with village inspections during construction11, and Health Department inspection of the septic system16.
- Secure a certificate of occupancy before anyone sleeps or cooks in the building5.
What stays with Lake County, and what to check before you buy in North Barrington
The village sets zoning and building permits inside its limits, but Lake County keeps septic and well permitting148. Lake County's own zoning ordinance covers only unincorporated land, and municipalities regulate lands within their boundaries18. For land outside village limits, use the Lake County page.
Before you buy, confirm the zoning district and lot dimensions with the village, and ask the Lake County Health Department whether a septic system and well are feasible on the lot. USDA soil ratings show 0% of Lake County soils as not limited for a conventional septic drain field, so expect a site evaluation and possibly an engineered system19. Lake County's effective property tax rate is 2.7%20.
Watch-outs
- Setbacks, minimum dwelling size, accessory dwellings, short-term rentals, driveway permits and floodplain rules inside the village were not confirmed; ask the Building Department at (847) 381-600010.
- A draft zoning code update is in progress, with final approval expected in early 2027, so check the current code before relying on a district rule1.
- Do not send a North Barrington address to Lake County Planning, Building and Development for building permits: that office's rules apply to unincorporated Lake County only21.
