How much would a deck with structural reinforcement cost?

The cost of building a deck with structural reinforcement depends on factors like the deck’s size, materials, design complexity, and local labor rates. For example, a second-story or multi-level deck with extra structural support will generally have a higher price tag due to enhanced framing and foundation needs.

Typical Cost Ranges:

• A 200–400 sq. ft. second-story deck may range from $14,000 to $28,000, or about $65–$75 per square foot 
• Material choice matters: pressure-treated wood is usually most affordable, while composite decking can run $30–$45 per square foot for materials alone 
• Reinforcing beams or joists, especially on rooftop decks, might add $11–$22 per square foot 

Additional factors include labor rates (often 50–60% of total cost), permit fees, building code requirements, and any custom features you’d like to add.

For the most accurate estimate tailored to your needs, it’s best to consult with a professional contractor.
