TL;DR
Private equestrian arenas in Loudoun and Fauquier counties cost $25-$40/sq ft outdoors and $45-$70+/sq ft covered in 2026. Most qualify for agricultural-structure permitting unless covered or occupied, and success depends on proper geotextile and drainage work in Virginia's clay soils.
Key Takeaways
- Private arenas on agricultural land often qualify for a lighter agricultural-structure review, but covered or occupied arenas usually need a standard building permit.
- Virginia clay soils require a geotextile layer and drain tile; skipping either is the top cause of arena failure within 3-5 years.
- Outdoor arenas run $25-$40/sq ft in 2026; covered/indoor arenas run $45-$70+/sq ft.
- Standard dressage arenas are 20m x 40m or 20m x 60m; jumping arenas are typically 100 x 200 ft or larger.
- Confirm zoning status (AR-1, AR-2, conservation easement, floodplain) before design begins, not after.

Hearthstone Design Build is a Virginia Class A licensed design-build firm (License #2705195817) based in Leesburg that designs and builds indoor and outdoor equestrian arenas across Loudoun, Fauquier, and Clarke counties. A private riding arena typically runs $25-$70 per square foot depending on footing, drainage, and whether it is covered, and most arenas need a zoning or building permit review before site work starts.

Why equestrian arena construction is different from a standard barn
An arena is a civil and geotechnical project before it is a structure. The work that determines whether an arena rides well for 20 years happens below grade: subgrade compaction, a crowned or laser-graded base, a drainage layer, and a footing system matched to the discipline and the county's native soils. A barn builder who treats an arena as "flat ground with a fence" is the most common source of arenas that pond water, develop hard spots, or need re-footing within five years. For the same reason we size and engineer barns to use rather than a default footprint, see our barn builder guide; we size arenas to discipline and horse count the same way.
Arena sizing: dressage, jumping, and multi-discipline standards
| Arena type | Typical dimensions | Notes |
|---|---|---|
| Dressage (standard) | 20m x 40m (66 x 132 ft) | Minimum for recognized tests |
| Dressage (long) | 20m x 60m (66 x 197 ft) | Required for upper-level tests |
| Jumping / multi-discipline | 100 x 200 ft or larger | Allows a full course plus warm-up track |
Hearthstone sizes every arena to the rider's actual discipline and horse count rather than defaulting to a standard footprint, since an oversized arena adds footing and drainage cost without adding usable training value.
Permitting an equestrian arena in Loudoun and Fauquier counties
Most private arenas on agriculturally zoned land in Loudoun (AR-1, AR-2) and Fauquier qualify for an agricultural structure review rather than a full commercial building permit, but that exemption depends on the structure having no spectator seating, no commercial events, and no enclosed occupied space beyond a viewing area. Add a covered arena with walls, lighting, or a tack room under roof, and the county typically requires a standard building permit with structural drawings stamped by a licensed engineer. Projects near a floodplain, stream buffer, or conservation easement also trigger an additional site review before grading can start. See our AR-1 zoning guide and AR-2 zoning guide for how that review works, and confirm zoning status before design begins, not after.
Footing and drainage for Virginia's clay soils
Loudoun and Fauquier soils are predominantly clay-based, which holds water and compacts hard when wet, then cracks when dry, the opposite of what a riding surface needs. A correctly built Virginia arena has: a compacted subgrade, a geotextile fabric layer, 4-6 inches of compacted aggregate base with positive drainage or perimeter drain tile, and a footing mix (sand, sand/fiber blend, or engineered footing) sized to the discipline. Skipping the geotextile layer or the drain tile is the single most common cause of arenas that fail within three to five years in this region. Our site grading and drainage guide covers the same principles that apply here.
Indoor vs. outdoor arena cost in Virginia
Outdoor arenas with proper base and footing generally run $25-$40 per square foot in Loudoun and Fauquier in 2026, before fencing and lighting. Covered or fully indoor arenas, which add a timber or steel structure, roofing, and often lighting and ventilation, run $45-$70+ per square foot depending on clear span and finish level. A 100 x 200 ft indoor arena (20,000 sq ft) at the middle of that range lands in the $1.1M-$1.4M range installed; an outdoor arena of the same footprint lands closer to $500K-$800K. These are planning ranges, not quotes; final numbers depend on soil testing, grading cut/fill, and access for equipment. For adjacent barn costs, see our horse barn cost guide.
What a design-build team handles that a footing contractor doesn't
A footing-only contractor installs base and surface to a spec someone else provides. A design-build firm determines that spec: soil testing, grading design, drainage calculations, structural engineering for any covered portion, zoning and permit coordination, and sequencing the arena against the rest of an estate's build-out: barn, paddocks, run-in sheds, and utilities. Hearthstone's estate work, including the Tuttaposto timber frame home and outdoor living projects across Loudoun's hunt country, follows the same single-contract model: one firm accountable from soil testing through final grading.
Where to start
Confirm the parcel's zoning and any easement restrictions first, then size the arena to discipline and horse count before pricing footing. If you want Hearthstone in that comparison, request a feasibility review or schedule a consultation.

Frequently Asked Questions
What size should a private equestrian arena be?
Standard dressage arenas are 20m x 40m (66 x 132 ft) or 20m x 60m (66 x 197 ft). Jumping and multi-discipline arenas typically run 100 x 200 ft or larger to fit a full course and warm-up track.
Do I need a permit to build a riding arena in Loudoun or Fauquier County?
Open, unoccupied arenas on agricultural land often qualify for a lighter agricultural-structure review. Covered arenas with walls, lighting, or a tack room under roof typically need a standard building permit with engineer-stamped structural drawings.
What is the cost difference between an indoor and outdoor arena?
In 2026, outdoor arenas in Loudoun and Fauquier generally run $25-$40 per square foot. Covered or indoor arenas run $45-$70+ per square foot depending on clear span and finish level.
What footing works best for Virginia's clay soils?
A compacted subgrade, a geotextile fabric layer, 4-6 inches of compacted aggregate base with drainage or drain tile, and a sand or engineered footing mix sized to the discipline. Skipping the geotextile layer is the most common cause of early arena failure in this region.
Can an equestrian arena be built on land under a conservation easement?
Sometimes, but it requires an additional site review, and some easements restrict new impervious or agricultural structures. Confirm easement terms and zoning status before design begins.
