- Homes and accessory structures of 5,000 sq ft or more need an automatic fire sprinkler system.
In Teton County, 5,000 sq ft brings sprinklers. A large barn or shop at that size needs an automatic fire sprinkler system, which changes the budget. We flag it early so you can choose the size knowing the full cost.
