Frequently Asked Questions
Do I need a building permit for a deck in Minnesota?
Yes, in most MN jurisdictions, a permit is required if the deck is attached to the house, higher than 30 inches above the ground, or more than 200 square feet in size.
How much does a new deck cost in Minnesota in 2025?
A mid-sized deck typically ranges from $10,000 to $25,000. Basic pressure-treated wood starts around $35-$45 per square foot, while premium composite decks can exceed $100 per square foot.
Can I use a standard concrete slab for a patio in MN?
Standard concrete slabs are prone to cracking during Minnesota's freeze-thaw cycles. Pavers or air-entrained concrete are recommended as they offer better flexibility and durability against shifting soil.
What are the railing requirements for MN decks?
Decks more than 30 inches above grade must have guards at least 36 inches high, with balusters spaced so that a 4-inch sphere cannot pass through.
