The biggest risks in a barn you just bought are fire, injuries from stall and aisle hardware, and an emergency you haven't planned for. Start with an electrician's inspection and a hay-storage routine, then fix doors, latches, and clutter, and finally write down a fire and hurricane plan using the NC Department of Agriculture's farm emergency template. Most of this costs little, and the first two steps matter most.

Your barn may never have been inspected

North Carolina exempts most farm buildings from the state building rules.

"Building rules do not apply to (i) farm buildings that are located outside the building-rules jurisdiction of any municipality"

NC General Assembly, G.S. 143-138

The statute defines a farm building to include any structure used for equine activities, including the care, boarding, or training of horses and the instruction of riders, along with sheds and barns that store equipment for those activities. One exception: any grandstand or other spectator seating in a farm building still gets an annual safety inspection.

The practical result is that a barn outside a town's building-rules jurisdiction may have been built and wired with no inspection at all. That isn't a reason to avoid a farm, but it is a reason to hire a licensed electrician to look at the barn in your first month, or better, during your due diligence period. Our horse farm inspection checklist lists the other building checks.

Fire: what starts barn fires

Penn State Extension's guide to fire safety in horse stables is blunt:

"There is no such thing as a fireproof building, especially in agricultural settings."

Penn State Extension, Fire Safety in Horse Stables

The same guide cites an estimate that careless smoking is the root cause of 95 percent of preventable horse barn fires, with faulty electrical systems high on the list. It says most barn fires happen in winter, when the most hay and bedding is stored, electrical use is high, and repair projects are underway.

Barn fires also move fast. Penn State notes that straw reaches burning temperature in 1 to 5 minutes and that a straw fire can cover an area 10 feet across in 2 to 3 minutes, about the size of a box stall. Once flames appear, a building can reach flash point in as little as 3 to 5 minutes. Prevention and early detection matter far more than firefighting.

Wiring: the first thing to fix

Penn State's recommendations translate into a checklist for your electrician:

All wiring in conduit. PVC is preferred in humid barns, and rodents chew exposed insulation.
Light fixtures and fans rated for agricultural use, with dust- and moisture-resistant covers, and UL-listed products throughout.
No overloaded circuits or outlets. Inspect and clean panels, wiring, and fixtures regularly.
A master switch near the entrances, so rescuers have light.
Heat tapes discouraged. If you use them, follow every manufacturer warning.
Space heaters used only according to manufacturer guidelines and never left unattended.

Penn State also recommends a lightning protection system on every barn, installed by a certified installer and inspected periodically. It notes lightning storms are most common in the central and eastern United States.

Post a no-smoking rule for the barn and its surroundings. If visitors smoke, give them a spot away from the building with a proper receptacle.

Hay: the fire that starts itself

"The majority of hay fires occur within 6 weeks of baling, usually caused by excessive moisture in the bale."

Penn State Extension, Fire Safety in Horse Stables

Penn State puts the ideal moisture for hay at baling at 15 to 18 percent. Wetter hay can heat as microbes grow inside the bale. Check newly stored hay twice a day for heat during those first weeks, especially loads bought in summer. A hay probe thermometer is the right tool. Penn State's temperature guide:

Interior bale temperature	What it means	What to do
Below 130°F	No problem	Keep checking new hay
130°F to 140°F	No problem yet; may rise or fall	Recheck in a few hours
150°F	Likely to keep climbing	Move hay to let air cool it; check often
175°F to 190°F	Fire is imminent or nearby	Call the fire department; keep monitoring
200°F or above	Fire at or near the probe	Call the fire department; cool hot spots with water and have a charged hose ready before moving hay

Without a probe, Penn State suggests driving a 3/8- to 1/2-inch metal rod into the stack and leaving it 15 to 20 minutes. If you can't hold it comfortably in a bare hand, the bale is at or above about 160°F. When you call, tell the dispatcher you have hot hay that may ignite.

Storage matters as much as moisture. One strong recommendation from Penn State is to keep hay and bedding in a separate building from the horses, which also cuts barn dust. If that isn't possible, store it in its own section, stack bales on their sides on pallets, and keep trucks and equipment with hot exhausts out of the hay area.

Water, extinguishers, and access for the fire department

Mount a charged ABC-type extinguisher about every 50 feet in the barn.
Install more than one frost-free hydrant in and around the barn, or keep enough hose to reach every stall.
Make sure a fire truck can get in. Penn State calls a 12-foot lane sufficient and says bridges should carry a 40,000-pound truck.
Keep other buildings 50 to 100 feet from the stable, to slow fire spread and leave room for equipment.
A pond can help firefighters, but Penn State notes the water source should be no more than 20 feet below the pump truck.
Ask a fire protection professional about detection. Penn State notes household smoke detectors give false alarms in dusty, humid barns, while heat detectors are reliable but slower. A phone dialer that calls you or a neighbor adds value if no one lives near the barn.

NFPA 150 as a design reference

The National Fire Protection Association publishes NFPA 150, the Fire and Life Safety in Animal Housing Facilities Code. NFPA describes it as covering all types of animal housing facilities, including barns and stables, and the current edition is 2025. NFPA's code page links to free online access for reading NFPA 150. If you're building a new barn or doing a major renovation, use it as a reference and ask your local fire marshal what applies to your property.

Stalls, doors, latches, and aisles

Fire is the rare disaster. Hardware injuries happen every week. Penn State Extension's stall design guidance gives clear targets:

"Swing doors should open into the aisle rather than into the stall."

Penn State Extension, Horse Stall Design

Its fire guide explains why: a panicked horse can catch a hip on a half-open door, and a horse pushing out on an outward-opening door can escape on its own once the latch is open. Open swing doors do narrow the aisle, so latch them back when they're open.

Walk every stall with this list:

Latches that open quickly with one hand, so a person can run the aisle in a fire and release every horse.
Smooth surfaces. Penn State says stall interiors and hardware need to be "smooth, rugged, and free of projections." Look for protruding bolts, bent bars, broken boards, and exposed nail points.
Stall size. Penn State calls 12 by 12 feet the standard for a 1,000-pound horse and doesn't recommend walls under 10 feet long.
Windows placed out of reach (generally above 7 feet) or covered with sturdy bars or mesh. Plexiglas is a good glazing choice.
Buckets fastened to the wall with the rim just above chest height, away from the feed tub.
A halter and lead rope at every stall door, so anyone can lead a horse out in an emergency.

Keep aisles and doorways clear of wheelbarrows, hoses, and equipment. Penn State stresses that a blocked exit is not an exit, and recommends that barn exits open into a fenced area so loose horses can't reach a road.

Emergency plans: fire, hurricane, and flood

Write it down

The NC Department of Agriculture's Emergency Programs Division publishes a free Farm Emergency Plan Template. It asks you to map barns and outbuildings, roads, gates, wells, hydrants, ponds, electrical shutoffs, fuel tanks, animal areas, and manure storage, and to list contacts including the NCDA&CS Emergency Hotline (1-866-645-9403). Penn State adds that the plan should be posted by the phone, and that the local fire department should have a map showing where horses are housed, where water is, and where chemicals are stored.

Practice with your horses

Penn State recommends evacuation drills, including teaching horses to walk out with their eyes covered and getting them used to firefighter gear, sirens, and smoke. It notes that most firefighters are volunteers who may have little horse experience, and that some fire companies will train with you. Invite yours out.

Hurricane season

The Atlantic hurricane season runs June 1 to November 30, according to the National Hurricane Center. NCDA&CS links horse owners to the ASPCA's disaster planning guide for horses, which recommends:

Permanent ID such as a microchip, plus a backup like a luggage tag braided into the mane.
Practicing trailer loading in calm conditions, and checking trailer tire pressure, brake battery, and safety chains.
A 7 to 10 day supply of feed and water, with each horse's diet and medications written down.
Vet records, including a current Coggins test, and proof of ownership with photos.
At least two routes to your evacuation site, and leaving as soon as authorities order an evacuation.
A buddy system with nearby horse owners to share trailer space and hay.

Keep in mind that a power outage stops an electric well pump. A generator sized for the pump, or stored water, keeps horses drinking until power returns. Our seasonal maintenance checklist puts storm prep on the calendar.

A first-month checklist for new owners

Have a licensed electrician inspect the barn wiring, panel, and fixtures.
Post no-smoking signs and set the rule for everyone who works at the farm.
Buy a hay probe thermometer and check new hay twice a day for six weeks.
Mount ABC extinguishers about every 50 feet and confirm hydrants work.
Rehang or replace inward-swinging doors, and fix slow or broken latches.
Clear aisles and exits, and hang a halter and lead at every stall.
Fill out the NCDA&CS Farm Emergency Plan and give your fire department a copy of the map.
Assemble a hurricane kit and practice loading every horse.
