Frequently Asked Questions

Do I need a building permit for a deck in South Dakota?

Generally, yes. Most SD cities require a permit if the deck is attached to the house, covered by a roof, or more than 30 inches above the adjacent grade.

What is the average cost of a deck in South Dakota?

A professional deck installation typically ranges from $15,000 to $45,000. Basic pressure-treated wood starts around $85 per square foot, while high-end composite decks often exceed $150 per square foot.

When is the best time of year to build?

Late spring and early fall are ideal. Avoid mid-winter as the frozen ground makes excavating for the required 42-inch footings nearly impossible without specialized equipment.

Are railings required for low-profile decks?

In South Dakota, guardrails are mandatory for any deck or landing that is more than 30 inches above the ground. The rail must be at least 36 inches high.
