Frequently Asked Questions
Do I need a building permit for a deck or patio in Michigan?
Generally, yes. Most Michigan municipalities require a permit for any deck attached to the house or any freestanding deck higher than 30 inches. Ground-level patios under 200 square feet may be exempt in some jurisdictions, but you should always verify with your local building department.
How much does a deck addition cost in Michigan?
For 2024-2025, professional deck installation in Michigan typically ranges from $35 to $65 per square foot. A standard 300-400 sq. ft. deck costs between $15,000 and $25,000, depending on whether you choose pressure-treated wood or high-end composite materials.
What is the best time of year to build in Michigan?
The ideal window is late spring (May) through early autumn (October). While builders can work in winter, frozen ground makes digging the required 42-inch footings significantly more difficult and expensive.
What are the railing height requirements?
In Michigan, any deck surface more than 30 inches above the ground requires a guardrail at least 36 inches high. Balusters must be spaced close enough that a 4-inch sphere cannot pass through them.
