Cost of Building a Deck in Franklin, TN (2024 Guide)
What's the cost of building a deck in Franklin, TN? This guide covers average prices, materials, size, and what drives the final number. Updated for 2024.
What Does It Cost to Build a Deck in Franklin, TN?
The cost of building a deck in Franklin typically runs between $8,000 and $30,000 for most residential projects. That's a wide range — and it's wide for a reason. A simple 200-square-foot pressure-treated platform off the back door is a very different project from a 600-square-foot multi-level composite deck with built-in seating and a pergola. This guide breaks down what actually drives the number so you can budget realistically.

The Biggest Cost Drivers
1. Deck Size
Size is the single biggest factor in the cost of building a deck. More square footage means more materials and more labor hours. Most Franklin homeowners build decks in the 200–500 range, with larger projects running 600 or more.
A rough rule of thumb: budget $25–$45 per square foot for pressure-treated lumber and $45–$75 for composite, all-in including framing, decking, railings, and stairs. See our detailed cost-per-square-foot breakdown for more on how those numbers work.
2. Decking Material
Material choice has a major impact on the total cost for building a deck:
- Pressure-treated lumber — Most affordable upfront. Requires periodic sealing or staining. Typical all-in range: $25–$38 per square foot.
- Composite decking — Higher upfront cost, minimal maintenance, 25-year warranties on quality boards. Typical all-in range: $45–$70 per square foot.
- Hardwood (Ipe, Tigerwood) — Premium appearance, very durable, but expensive and requires careful installation. Typical all-in range: $55–$85 per square foot.
3. Complexity and Features
A flat, single-level deck attached to a house on flat ground is the simplest and least expensive configuration. Costs climb with:
- Multiple levels — Each level change adds framing complexity and labor
- Stairs — Especially cascading or L-shaped stair systems
- Built-in features — Bench seating, planters, pergolas, outdoor kitchen rough-in
- Sloped yards — Common in Franklin's rolling terrain; requires taller posts and more complex framing
- Railing style — Cable railing and glass panel systems cost significantly more than standard balusters
4. Permits and Inspections
Building a deck cost in Williamson County includes permit fees, which typically run $150–$400 depending on project value. Franklin Deck Building Pros handles the permit application and inspection scheduling on every project — it's included in our quote, not a surprise add-on.
5. Site Conditions
Difficult site access, rocky soil requiring deeper footings, or an existing structure that needs to be removed first all add to the total. We assess site conditions during the free estimate so nothing catches you off guard.
Average Cost of Building a Deck by Size
Here's a rough guide to the average cost of building a deck at common sizes in the Franklin area:
| Deck Size | Pressure-Treated | Composite |
|---|---|---|
| 200 sq ft | $5,000–$7,600 | $9,000–$14,000 |
| 300 sq ft | $7,500–$11,400 | $13,500–$21,000 |
| 400 sq ft | $10,000–$15,200 | $18,000–$28,000 |
| 500 sq ft | $12,500–$19,000 | $22,500–$35,000 |
These are all-in estimates including framing, decking, basic railing, one stair run, and permit. Custom features, complex sites, and premium railing systems will push costs higher.
What's NOT Included in Most Deck Quotes

Is It Worth It?
The cost of deck building is real, but so is the return. A well-built deck in Franklin adds usable living space, improves curb appeal, and typically returns 60–80% of its cost at resale according to national remodeling cost-value data. More importantly, it gives your family a place to actually use your backyard from April through October.
