The short answer

On the Front Range it takes 25 to 40 acres of dryland pasture to support one horse with no supplemental feed, per CSU Extension. Irrigated pasture carries a horse on 0.7 to 1.2 acres. On smaller mountain acreage, plan to feed hay; the legal number of horses comes from county zoning, not grass. Confirm the count for a specific parcel with the county planning office.

Questions

How many acres do you need per horse in Colorado? On the Front Range it takes 25 to 40 acres of dryland pasture to support one horse with no supplemental feed, per CSU Extension. Irrigated pasture carries a horse on 0.7 to 1.2 acres. On smaller mountain acreage, plan to feed hay; the legal number of horses comes from county zoning, not grass. Confirm the count for a specific parcel with the county planning office.
Can I keep horses on 5 acres in Jefferson County? Yes, in most cases. In the A-1 zone (5-acre minimum), A-2 (10 acres) and A-35 (35 acres), Jefferson County sets no limit on animals when the lot meets the zone minimum. In residential zones and undersized agricultural lots the county requires 9,000 square feet of open land for the first animal and 6,000 square feet for each additional one, with a cap of 4 per acre. Confirm the parcel's zone with Jefferson County Planning and Zoning before you buy.
How many horses can I keep on 1 acre in Jefferson County? Up to 4, and only when the acre is open land. Residential zones in unincorporated Jefferson County require 9,000 square feet of open land for the first animal and 6,000 square feet for each additional animal, capped at 4 per acre. Inside Golden or Morrison town limits, the city or town code applies instead.
What are the horse rules in Clear Creek County (Idaho Springs, Georgetown)? Clear Creek County does not allow non-commercial animals on parcels under 3 acres. The limit is 1 animal unit per acre; one horse equals one unit and two miniature horses equal one unit. Corrals sit at least 10 feet from property lines, and manure stays 200 feet from wells and streams and outside the 100-year floodplain. Inside Idaho Springs or Georgetown town limits, confirm with the town.
How many horses can I have in Park County (Bailey)? It depends on the zone. The Agricultural zone has no animal limit. In A-35, R-35 and R-20, the base is 4 horses times an acreage factor: 16 horses on 35 to 70 acres, and 8 on R-20 lots of 10 to 20 acres. In the Residential zone, lots over 1 acre allow 1 animal per 20,000 square feet of open space, up to 4. Barns and corrals sit 50 feet from dwellings and 100 feet from wells and watercourses.
What are the horse rules in Boulder County mountain areas (Nederland, Lyons, Allenspark)? Boulder County counts animal units per acre by zone: 4 in Agricultural, 2 in Forestry, Rural Residential and Estate Residential, and 1 horse per half acre of pasture in Suburban Residential. The code states: "Riding horses may be kept as permitted accessory uses provided at least one-half acre of pasture is available for each horse." Outdoor arenas sit 300 feet from neighbors' homes. Inside Nederland or Lyons town limits, the town code applies.
How many horses per acre in Larimer County (Estes Park area)? Unincorporated Larimer County allows personal horses in every zoning district that allows single-unit dwellings, at no more than one animal per half acre of lot. The rule covers horses for the occupants and their guests, not boarding or training. Inside Town of Estes Park limits, the town code applies; confirm with the town.
How many horses can I keep in Teller County (Woodland Park)? In Teller County's R-1 and R-1M zones, horses are not allowed on lots under 1 acre. In the RR, R-1 and R-1M zones the maximum is one animal per half acre on lots of 1 acre or more. Two or more animals require a barn or shelter, and corrals, stalls and barns sit at least 50 feet from any property line. Inside Woodland Park city limits, the city code applies.
Can I keep horses in Gilpin County? Yes. Gilpin County states that horses are permitted in all zones, provided the property has adequate space to house them. Most private land is zoned RR (Resource Residential) or RS (Residential Subdivision), and the primary dwelling must be built before a barn or other accessory structure. Ask Gilpin County Community Development for the animal count on a specific parcel.
How many horses per acre in Elbert County (Elizabeth, Kiowa)? Elbert County allows 1 animal unit per half acre in the RA, RA-2, RA-1, AR and A-2 zones and on non-conforming parcels under 35 acres; one horse equals one unit. The R-1 zone allows two equine, and the R-2 zone allows no horses. When animals exceed one unit per 35 acres, a corral is required, no larger than 10% of the lot or half an acre, whichever is less.
Why do horse buyers look for 35 acres in Colorado? Two reasons. Parcels of 35 acres or more are exempt from county subdivision review under C.R.S. 30-28-101. And a 35-acre-plus parcel qualifies for a domestic well that waters livestock, while most smaller parcels get a household-use-only well that does not. Confirm the actual well permit with the Division of Water Resources.

water-wells

Can I water horses from a household-use-only well in Colorado? No. A household-use-only well serves inside one home only, with no outdoor watering and no livestock. Most wells drilled on or after May 8, 1972 on parcels under 35 acres carry this permit. Pull the permit on the DWR Well Permit Search before you write an offer on horse property.
What well permit do I need to keep horses in Colorado? A domestic and livestock well. On parcels of 35 acres or more, one such well per parcel serves up to three single-family homes, irrigates one acre or less of lawn and garden, and waters domestic animals and livestock. Confirm the permit's listed uses with the Colorado Division of Water Resources.
Why does my neighbor's well allow livestock when mine does not? CSU Extension points to the date: the neighbor's well was installed before May 8, 1972, and the livestock use already existed. Wells permitted after that date on parcels under 35 acres are household-use only. Each well's permit sets its uses, so check both permits on the DWR Well Permit Search.
How do I check the well permit on a horse property? Look up the property on the Colorado Division of Water Resources Well Permit Search. The permit lists the allowed uses, such as household-use only or domestic and livestock. After closing, the new owner files a change-of-owner form with DWR; there is no fee.
Do I need water rights to irrigate horse pasture in Colorado? Yes, for anything beyond the exempt-well allowance. An exempt domestic and livestock well on 35 acres or more irrigates one acre or less of lawn and garden. CSU Extension states that wells for other uses, such as irrigation, are non-exempt, are administered in the priority system, and must have augmentation plans in over-appropriated basins. Ask the seller for decrees and ditch share records and confirm them with the Division of Water Resources.

hay-feed

How much hay does a horse eat per day? An average 1,000-pound horse eats 1.5 to 2% of its body weight in feed each day, about 15 to 20 pounds of hay, pasture and grain, per CSU Extension. An idle mature horse can live on forage alone at 15 to 25 pounds of hay a day. Ask your vet to set the ration for age, work and body condition.
How much more hay does a horse need in a Colorado winter? Below 18 degrees F, a horse with a winter coat needs 1% more energy for every degree of cold. A 1,000-pound idle horse eating 16 pounds of good hay at 18 degrees F needs about 18 to 18.5 pounds at 0 degrees F, and more without shelter. Forage, not grain, is the best source of that extra heat.
How much is hay in Colorado right now? The USDA Colorado Direct Hay Report for Sept 24, 2026 lists fair-grade grass hay in the Mountains and Northwest region at $300 per ton, medium square bales picked up in the field. In the Northeast region, premium mixed grass small squares sold for $15.25 to $16.00 a bale at the stable. The next report is due Oct 8, 2026.
Can horses graze year-round on mountain pasture? No. CSU Extension states that during snow cover, and any time no forage is available, supplemental hay must be provided. On dryland pasture using the take-half, leave-half rule, one 1,000-pound horse needs 28.8 acres a year. Plan hay storage for the full winter.
Do I need weed-free hay to ride in the national forest? Yes. Only certified weed-free hay and forage is allowed on National Forest System lands, including the Pike-San Isabel National Forest. The Colorado Department of Agriculture's Weed Free Forage Directory lists certified producers by city, forage type and bale size.

structures-permits

Do I need a permit for a loafing shed in Jefferson County? Yes. Loafing sheds under 1,000 square feet need a Miscellaneous Permit, and sheds over 1,000 square feet need a Building Permit. Under the 2024 Jeffco Building Code Supplement, three-sided agricultural structures up to 1,000 square feet and at least 50 feet from habitable structures are exempt from a building permit. Confirm with Jefferson County Planning and Zoning before you build.
Do I need a permit to build a horse barn in Jefferson County? Yes. Jefferson County requires a Building Permit for all barns, barn replacements and modifications. Residential zones require a house on the property before a barn; agricultural zones allow a barn as a standalone use. In the Wildland Urban Interface, barns more than 50 feet from a habitable structure are exempt from structure hardening and defensible space requirements.
Do I need a permit for a horse fence in Jefferson County? No permit for fences in unincorporated Jefferson County. A gate across an access serving a parcel needs a Miscellaneous Permit, first approved by the fire protection district. In the Wildland Urban Interface, fencing within 8 feet of the home must be noncombustible under the county's wildfire code.
Which sheds are permit-exempt outside Jefferson County? Clear Creek County exempts sheds up to 120 square feet. Park County exempts sheds up to 200 square feet. Boulder County exempts structures up to 120 square feet, and agricultural loafing sheds up to 200 square feet, when 12 feet tall or less with no utilities. Clear Creek allows no accessory structure without a principal use, and Park County requires a dwelling first on most properties.
What size run-in shed do two horses need? University of Minnesota Extension lists 240 square feet (12 by 20 feet) as ideal for two horses that get along, plus 60 square feet for each additional horse. CSU Extension lists box stalls at 10 by 10 to 12 by 12 feet with an 8-foot minimum ceiling. Check the county permit threshold before you build.

fencing-law

Is Colorado a fence-out state? Yes. In Colorado, livestock owners are not required to fence animals in; a landowner who wants livestock off the land fences them out. Only an owner with a lawful fence in good repair recovers damages when livestock break through (C.R.S. 35-46-102). Separate laws cover livestock on public highways and inside towns.
What is a lawful fence in Colorado? C.R.S. 35-46-101 defines it as "a well-constructed three barbed wire fence with substantial posts set at a distance of approximately twenty feet apart," sufficient to turn ordinary horses and cattle, with gates as good as the fence. For fence-law purposes, livestock includes horses, mules and asses.
What horse fence works with elk and deer? Colorado Parks and Wildlife recommends a top wire at 42 inches or lower, 12 inches between the top two wires, a bottom wire at least 16 inches off the ground, and smooth top and bottom wires. CPW states 42 inches "really is adequate to keep in nearly all breeds of horse." Check HOA covenants and county wildfire fence rules before building.
What is the safest fence for horses? CSU Extension says the fence must be visible to the horse so it does not run through or tangle in it. Board, rail or wide ribbon electric wire meets that test; plain wire must be smooth. CSU Extension warns that barbed wire causes injuries to horses.

wildlife-predators

Do mountain lions attack horses in Colorado? Yes. CPW says lions prefer deer but also hunt livestock and domestic animals, and it reimburses documented damage to livestock, including horses. CPW advises placing livestock in enclosed sheds or barns at night, closing doors to all outbuildings, and not attracting deer to your property.
Who pays if a mountain lion or bear kills my horse? Colorado Parks and Wildlife's Game Damage program reimburses documented damage to livestock from big game, including black bear and mountain lion. Contact the local CPW office and ask for the District Wildlife Manager immediately upon discovering damage. Eligibility has conditions, including not unreasonably restricting hunting of the damaging species.
Is locoweed a problem for horses in the Colorado mountains? Yes. Colorado has three main locoweeds: purple, white and woolly. Horses are poisoned by eating any part of the plant, even dry, with signs after 2 to 3 weeks of grazing it; CSU Extension says locoed horses "should be considered permanently affected." No mineral or feed additive has proven effective against it, so walk the pasture and call your vet or CSU Extension about control.

wildfire-evacuation

Where do horses go in a Jefferson County wildfire evacuation? The Jeffco Fairgrounds, 15200 West 6th Avenue in Golden, is the large animal evacuation center; the Jeffco Sheriff's Office activates it. Small animals go to Foothills Animal Shelter. Fairgrounds phone: 303-271-6600; updates post on its social media during activations.
Where do horses go in a Boulder County wildfire evacuation? The Boulder County Fairgrounds is the evacuation location for large animals, and loose large animals found in the field go there for reunification. If you must turn animals loose, Boulder's Office of Disaster Management says to close barn doors and cut fencing at the corners. Microchip horses and practice trailer loading ahead of time.
What should be in a horse wildfire evacuation kit? CSU's veterinary hospital lists a halter and lead rope, feed and water buckets, a 5 to 7 day supply of feed and supplements, and at least two weeks of daily medications for each horse. Carry the brand inspection, Coggins test, microchip number and vaccination records. Practice trailer loading with different trailers and handlers.

vet-health-winter

Where is the nearest 24/7 equine emergency hospital to the Colorado mountains? CSU's Veterinary Health System in Fort Collins runs equine emergency and critical care 24/7, year round, including colic, fractures and trauma. Call ahead at (970) 297-5000. Line up a regular equine vet and farrier before the horses move in.
What vaccines do horses need in Colorado? The AAEP lists tetanus, Eastern and Western equine encephalomyelitis, West Nile virus and rabies as core vaccines. The Colorado Department of Agriculture says horses vaccinated for West Nile in past years need an annual booster, and unvaccinated horses need the two-shot series. Set the schedule with your vet.
How often do horses need a farrier and dental care? CSU Extension says to trim hooves every six to eight weeks with a qualified farrier and to have a vet or equine dentist check and float teeth at least once a year. Your vet sets the deworming plan.
How do I keep horses drinking in a Colorado mountain winter? A 1,000-pound horse needs at least 10 to 12 gallons of water a day. Keep water between 45 and 65 degrees F; ponies drank about 40% more when water was above freezing in cold weather. Snow and ice are not adequate water sources. Check tank heaters for worn wires and stray voltage.
Do horses need a barn or blanket in a Colorado winter? Horses need shelter from wind, sleet and storms; an open-sided shed or trees work. With shelter, horses tolerate temperatures down to -40 degrees F. Blankets are needed when there is no shelter in severe wind chill, when the horse will get wet, is clipped, very young or old, not acclimated, or thin. Ask your vet about an older horse.
How much manure does a horse produce, and where can I pile it? A 1,000-pound horse produces about 50 pounds of manure a day, about 8.5 tons a year, plus bedding. Jefferson County keeps manure piles 100 feet back from the front lot line; Clear Creek County requires 200 feet from wells and streams. Compost that reaches 140 to 160 degrees F for over a week kills weed seeds and parasite eggs.

buying-legal-tax

Do I need a brand inspection when I buy a horse in Colorado? Yes. Colorado requires a brand inspection at any change of ownership, for moves of more than 75 miles within the state, and for any trip out of state. The horse inspection fee is $5.00 per head (fees effective Oct 1, 2025).
What paperwork do I need to bring a horse to Colorado? Livestock entering Colorado need a Certificate of Veterinary Inspection from an accredited vet, and a CVI is void 30 days after issuance. Species-specific requirements, including disease tests, come from the State Veterinarian's Office at 303-869-9130. Call before you haul.
Do horses qualify a property for agricultural tax status in Colorado? Not pleasure horses. In Palmer v. Eagle County Board of Equalization (1998), the Colorado Court of Appeals ruled that grazing and boarding pleasure horses is not a ranching use, because the horses are not used for food, breeding, draft or profit. Agricultural land must have been used the previous two years, and presently, as a farm or ranch for monetary profit. Confirm with the county assessor and a tax professional.

trails-riding

Can I ride horses in Jefferson County Open Space parks? Yes. Every Jeffco Open Space park allows horses and pack animals except Lookout Mountain Nature Center and Preserve and Mount Galbraith Park. White Ranch and Reynolds parks have equestrian-friendly campsites. All trail users yield to equestrians, groups are capped at 8 riders, and trailer parking is first-come, first-served.
