Building a horse stable – dimensions, permits and costs

From the beginning of 2026, the construction of horse stables will be guided by the new Government Decree on the Welfare of Horses (321/2025), which replaced the 2010 decree. The biggest changes: stalls for horses over 170 cm will increase to 10 square meters and those over 180 cm to 11 square meters, and the minimum size of the pens in new stables will be 300 m². The requirements will apply immediately to new construction and renovations - there is a transition period for stall sizes in existing stables until 1 January 2036.

Sizing of pens according to the new regulation

The minimum size of an individual pen is determined by the height at the withers:

• Up to 148 cm: 4–7 m² in stages depending on the height at the withers
• 148–160 cm: 8 m²
• 160–170 cm: 9 m²
• Over 170 cm: 10 m² (new requirement)
• Over 180 cm: 11 m² (new requirement)

In a group pen, there must be as much space per horse as in an individual pen, and the group pen rule is to size a mare and her foal according to the height at the withers of both. When planning a new stable, it is worth sizing it according to the largest horse imaginable - widening the pen row afterwards is expensive, and many half-warmbloods exceed the 170 cm limit.

Interior height and ventilation

The minimum requirement for interior height is 1.5 times the horse's height at the withers, but always at least 2.2 meters. In practice, it is advisable to plan a room height of at least 3.0 meters for a new stable, as gravity ventilation requires at least 2.7 meters to function. The air must be changed 4–8 times per hour, the ammonia concentration must remain below 10 ppm, carbon dioxide below 3,000 ppm and the relative humidity between 50–65%. In Finland, the most common solution is mechanical removal, which costs €2,000–6,000.

Farm, barn and distances

In new stables, the pen must be at least 300 m² in size and have a safe bottom and not be slippery or sinking. Daily walking is required, and riding or driving is not a substitute for penning. In the yard, a solid floor, a roof and four walls reaching to the ground, as well as a drained sleeping area at least the size of an individual pen per horse, are required. By 2031, new water and feeding requirements will also become mandatory: horses must be offered water at least every six hours and a continuous roughage fast may not last more than six hours – so it is worth planning a drinking system and automatic feeding for the stable immediately.

The manure shed is sized according to the Nitrates Regulation (1250/2014): it must cover 12 months of manure, approximately 17 m³ per horse per year, and must have a solid base and be covered or covered. Building a manure shed costs €3,000–10,000. Municipal guidelines recommend that stables, manure sheds and pens be located at least 50 meters away from neighboring objects that could be disturbed and that the construction site be approximately 2 hectares for two horses – the requirements are municipality-specific, so check your municipality's policy.

What permits does a horse stable require?

A stable is practically always at least 30 m², so it requires a building permit – currently called a construction permit. The processing takes 1–6 months and the fees are around €500–2,000. The place where horses are kept must be registered, and a notification must be made to the Licensing and Supervision Agency for professional or large-scale keeping, for example a stable with at least six horses. An environmental permit or notification is only required for units with at least 60 horses, but in groundwater areas the threshold can be met even with a smaller stable.

Why is a wooden frame the standard solution for stables?

A wooden frame is the most common frame solution for horse stables: it is cost-effective in small and medium-sized stables, easy to modify, and wood evens out the humidity in the stable – horses produce a lot of moisture. Logs are a premium option, about 30–40% more expensive. Steel frames are usually only used in large units and maneges.

Horse stable price 2026 and investment support

The price of a cold or unequipped stable is typically €700–1,200/m² in 2026, and a warm, equipped stable €1,200–2,200/m². Examples: a two-horse wooden frame stable costs around €14,800, a family stable with 3–4 stalls costs €40,000–90,000, and a stable with 6–8 stalls costs €90,000–180,000. Electrical and plumbing work costs €2,000–6,000, and stables with fences cost €2,000–10,000.

Agricultural investment support is available for construction investments in horse breeding: the grant is 35% and an interest-subsidized loan can be obtained for 50% of the costs, with a 10 percentage point increase for young farmers. The support does not apply to horse farming service activities, such as full-board or riding stables. Applications will be made from the beginning of 2026 from the vitality center, where the rural tasks of the ELY centers were transferred.
