Millbrook Horse Property: 7 Rules to Check First

Can you keep a horse on a Millbrook, IL property?

Sometimes, but the zoning district and the recorded covenants decide it, not the acreage. Millbrook horse property questions run through Kendall County’s zoning code, which lists farm-type animals as a permitted use only in the A-1 agricultural and R-1 residential districts. Most other residential districts do not list them, and some subdivisions near the village ban livestock in their covenants. Check both before you fall for a barn.

Millbrook is a small village on the Fox River in Kendall County, about 60 miles southwest of Chicago, and its own website invites people to explore the nearby forest preserves “by foot or by horse.”

That line catches the eye of buyers across Chicago’s Western Suburbs who want a few acres, a pasture, and room to ride. The listings look promising: big lots, outbuildings, and open views.

Here is the catch. A large lot is not the same thing as Millbrook horse property. These seven rules explain what decides whether a horse can live on a parcel, and what to check before you write an offer.

Rule 1: Find out who controls the parcel

Before you tour any Millbrook horse property, figure out which government writes the rules for it.

The Village of Millbrook was incorporated in 2002, and by our measurement of Kendall County GIS layers on October 17, 2026, it covers about 1,176 acres inside Fox Township.

For zoning and building permits, the village relies on the county. Kendall County Planning, Building and Zoning says it administers and enforces the county’s land development ordinances in unincorporated Kendall County and in the villages of Millbrook and Plattville, including building permits.

Many homes with a Millbrook address sit outside the village entirely. The village FAQ notes that the Estates of Millbrook subdivision is not within the corporate limits. A parcel a few miles away may fall inside Yorkville, Newark, Plano, or Millington, and those towns write their own rules.

For a Millbrook horse property, start with the Kendall County zoning map viewer. Look up the parcel, note the zoning district, and see whether a municipal boundary covers it. Our Millbrook community guide covers the village, its ZIP code, and nearby subdivisions in more detail.

Rule 2: Read the zoning district, not the lot size

Kendall County’s table of uses in the Kendall County Code is the place to start for any Millbrook horse property search. Here is how it treats animals:

• A-1 Agricultural: farm-type animals are permitted, and so are horse breeding and raising, grazing, and forage.
• R-1 One-Family Residential: farm-type animals are permitted. Ask Planning, Building and Zoning how many animals the R-1 rules allow on your lot.
• R-2 through R-7: farm-type animals are not listed as a permitted use.
• RPD planned developments: farm-type animals need a special use.

Fox Township is mostly farmland. By our GIS measurement, about 79.5 percent of the township’s acreage is zoned A-1. The subdivisions around the village are a patchwork, though. County zoning records show the Wedgewood Subdivision was rezoned from A-1 to R-1 in 1975, Foxhurst of Millbrook Unit 4 went from A-1 to R-3 in 1984, and The Woods of Silver Springs was rezoned to R-3 PUD in 1998.

So one Millbrook horse property listing can sit a short drive from a subdivision where the same horse would not be allowed. A 2-acre lot zoned R-3 does not become horse-friendly because it has room for a paddock.

What about chickens?

Chickens get broader treatment. The county’s table lists them as permitted in A-1, R-1, and R-2 through R-7, and as a special use in RPD districts, subject to the conditions in the code. Covenants can still say no, which brings us to Rule 4.

Rule 3: Boarding or lessons make it a riding stable

Keeping your own horse is one thing. Taking in boarders or giving lessons is a business use, and the county code treats riding stables as a conditional use in the A-1 district.

The A-1 rules in the code set conditions for a riding stable, including:

• The lot can be no nearer than 500 feet to a dwelling other than the owner’s home, or to a residential district.
• No more than 24 horses on the premises at any one time.
• No outdoor arena lighting beyond low-wattage security lights.
• A manure management plan submitted to the Kendall County Health Department.
• Indoor arena hours of 6 a.m. to 10 p.m., and outdoor riding from dawn to dusk.
• One parking space per stall.

Horse breeding and raising appears as a permitted use only in A-1. If income is part of your plan for a Millbrook horse property, ask the county which approvals the use needs before you buy, not after.

Illinois also has an Equine Activity Liability Act, and its warning rule (745 ILCS 47/25) applies to equine professionals. They must post a warning sign near their stables, corrals, or arenas, in black letters at least one inch tall. Talk with your insurance agent and attorney before you let anyone else ride.

Rule 4: Read the covenants before you write the offer

Zoning sets the floor for any Millbrook horse property. Recorded covenants can be stricter, and around Millbrook some are.

The Declaration of Covenants and Restrictions for the Estates of Millbrook, as re-recorded in 2009, says no livestock or poultry shall be kept on any lot. It also bars perimeter fencing and chain link or stockade fences, and it requires Architectural Review Committee approval before any building or fence goes up.

Buyers sometimes assume a covenant that was not recorded correctly does not apply. A 2013 Illinois Appellate Court order involving the Estates of Millbrook is a useful reminder. The original declaration was recorded in 2000 for sections one and two. When sections three and four were platted in 2004, the declaration was not re-recorded to cover them, so the association re-recorded it in 2009.

Owners in section four challenged the re-recording. The court affirmed that their lots were bound, pointing to their purchase contracts, closings, and mortgages, which acknowledged the association, and to the assessments they had paid. It was an unpublished order, so it is not binding precedent, but the lesson holds: read the declaration, and do not count on a technicality.

If a Millbrook horse property sits in a subdivision, ask the seller for the declaration, any amendments, and the association’s rules. Your attorney can review them during attorney review.

Rule 5: Plan barns and fences with the county

Kendall County’s building permits and forms page includes an Agriculture Exempt Permit Application, and a Health Department site evaluation request is required with it. Even an exempt barn on a Millbrook horse property goes through the county.

State law limits county zoning over land whose principal activity is agriculture, which the statute says includes animal husbandry and pasturage, and it requires permits for agricultural buildings to be issued free of charge. A pleasure horse on a home lot is a different question, so ask the county how your plan will be treated.

The same county page says no fence permit is required unless the fence is in the floodplain. If a Millbrook horse property backs up to a creek or the Fox River, check the floodplain before you plan pasture fencing.

Shared boundaries matter too. Under the Illinois Fence Act (765 ILCS 130/3), when two people own adjoining land, each must make and maintain a just proportion of the division fence between them. Walk the fence line during your inspection period.

Rule 6: Don’t count on a farmland tax assessment

Illinois assesses farmland differently from homes, and horses are on the list. The state’s definition of a farm in the Property Tax Code (35 ILCS 200/1-60) includes keeping, raising, and feeding livestock, ponies, or horses.

The same section adds that a farm does not include property used primarily for residential purposes, even if farm animals are bred or fed there as a side use. Under 35 ILCS 200/10-110, the farmland valuation also applies only after the land has been used as a farm for the 2 preceding years.

Keeping two horses behind the house will not usually turn a Millbrook horse property into an assessed farm. Ask the township assessor’s office how a specific parcel is classified before you budget around it.

Rule 7: Check water, septic, and riding access

Many rural homes around Millbrook rely on private wells and septic systems. The Estates of Millbrook building checklist, for example, asks for the well location and a septic site plan. Horses drink a lot of water, and manure storage needs a spot well away from both the well and the septic field.

Ask for the well’s age and any water test records on a Millbrook horse property, and order a septic inspection. Our guide to septic inspections in Kendall County walks through what buyers miss.

Then look at where you will ride from a Millbrook horse property. The Kendall County Forest Preserve District allows horseback riding on designated trails at Millbrook South Forest Preserve, 8563 Fox River Drive, as well as at Hoover, Harris, and Baker Woods. The Illinois Department of Natural Resources lists a seven-mile equestrian trail at nearby Silver Springs State Fish and Wildlife Area, closed during hunting seasons.

What the best real estate agents in Millbrook, IL check on horse property

Whoever you work with, the checks should look the same. Use this list on any Millbrook horse property before your inspection and attorney review deadlines run out:

1. Confirm the jurisdiction: village, unincorporated county, or a nearby city.
2. Pull the zoning district from the county map viewer and match it to the table of uses.
3. Ask Planning, Building and Zoning in writing whether your planned animals, and how many, are allowed.
4. Get the recorded declaration, amendments, and association rules, and read the animal and fence sections.
5. Check permit records for the barn, fencing, and any additions.
6. Test the well and inspect the septic system.
7. Check floodplain status before you plan fence lines or a manure area.
