Most deck projects in McKinney range from $8,500 to $28,000, depending on material, size, railing type, and whether HOA approval is required. Here's what drives the number and where McKinney-specific conditions affect cost.
McKinney Deck Cost by Material
| Material | Cost per Square Foot (installed) | 12x16 Deck (192 SF) | 16x20 Deck (320 SF) |
|---|---|---|---|
| Pressure-treated pine | $18–$24 | $3,500–$4,600 | $5,800–$7,700 |
| Cedar | $22–$30 | $4,200–$5,800 | $7,000–$9,600 |
| Trex Enhance (composite) | $32–$42 | $6,100–$8,100 | $10,200–$13,400 |
| TimberTech AZEK (composite) | $38–$52 | $7,300–$10,000 | $12,200–$16,600 |
| Multi-level composite w/ pergola | $55–$80 | $10,600–$15,400 | $17,600–$25,600 |
Prices include materials, labor, footings, framing, decking, railing, and stairs. Permit fees not included (typically $150–$400 in McKinney).
What's Different About McKinney Deck Projects
Footing Depth
McKinney sits on Blackland Prairie clay — soil that expands with moisture and contracts in summer drought. Standard code minimums for footing depth are insufficient for this soil type. We set footings at 36–48 inches depending on the deck's load and the site's drainage. A deck with shallow footings on McKinney clay will show post movement within 3–5 years. This adds some material cost (concrete) but is non-negotiable on our projects.
Stonebridge Ranch HOA Requirements
Stonebridge Ranch is the largest master-planned community in McKinney, and its ACC requires a full design submission before the city permit is pulled. The submission package — site plan, elevation drawings, material spec sheet, color selections — typically takes 2–3 days to prepare. The ACC review cycle is usually 2–4 weeks, and most submissions clear on the first round when the package is complete. Budget an extra 2–4 weeks in the schedule for Stonebridge Ranch projects before construction begins.
Cedar vs Composite in McKinney
Cedar is the standard privacy fence material across McKinney. It looks best when new and requires staining or sealing every 2–3 years to maintain color and prevent weathering. Unstained cedar turns gray within 1–2 North Texas summers. Composite decking — Trex and TimberTech AZEK are the systems we install most frequently — has a higher upfront cost but carries a 25-year fade and stain warranty and requires no annual maintenance. For homeowners done with the maintenance cycle, composite is the cleaner long-term option.

McKinney Permit Timeline and Process
McKinney deck permits are filed through the city's ePlanning portal. Standard residential deck permits take 1–3 weeks to process once submitted. If your property is in Stonebridge Ranch or another HOA community, add 2–4 weeks for the HOA design review before the city permit can be filed. We handle all submissions — HOA and city — on your behalf and track both timelines so construction starts the day permits clear.
When to DIY vs Hire a Contractor in McKinney
Simple surface-level tasks like restaining an existing cedar deck are reasonable DIY projects. However, any structural work — footings, framing, ledger board attachment, or railing post connections — should be done by a licensed contractor in McKinney. Footing depth in Blackland Prairie clay is not something you want to guess on, and McKinney's building inspection process requires a permitted contractor of record for structural deck work. An improperly attached ledger board is the #1 cause of deck collapses nationwide.

Frequently Asked Questions
Common questions about this topic from DFW homeowners and project planners.
How much does a deck cost in McKinney, TX?
Most deck projects in McKinney run $8,500–$28,000 depending on size, material, and railing type. Cedar starts around $8,500 for a 12x16. Composite (Trex, TimberTech AZEK) starts around $12,000 for the same size. Multi-level decks with pergolas run $18,000–$35,000.
Does Stonebridge Ranch require HOA approval before a McKinney deck permit?
Yes — the Stonebridge Ranch ACC requires design committee approval before the city permit can be filed. The review cycle is typically 2–4 weeks. We prepare and submit the full HOA package on your behalf, including drawings, material specs, and color selections.
What footing depth is required for decks in McKinney's clay soil?
We set footings at 36–48 inches on McKinney projects. Standard code minimums are insufficient for Blackland Prairie clay, which expands and contracts seasonally and will cause post heaving on shallow footings within a few years.
Is composite decking worth the cost over cedar in McKinney?
For McKinney homeowners who plan to stay in the home for 8+ years, composite pays for itself. TimberTech AZEK and Trex Transcend carry 25-year warranties and require no annual staining or sealing. Cedar requires refinishing every 2–3 years in North Texas — the maintenance cost adds up fast.
How long does a McKinney deck permit take?
After HOA clearance (if required), McKinney's ePlanning portal typically processes residential deck permits in 1–3 weeks. For Stonebridge Ranch projects, budget 2–4 weeks for the HOA review first, then 1–3 weeks for the city permit.
