Homeowners in Allen, Texas typically spend between $12,000 and $22,000 on a standard backyard deck in 2026, with composite and multi-level builds running $30,000 to $45,000 or more. Allen sits in Collin County alongside Plano, McKinney, and Frisco, and deck pricing here reflects both the strong local housing market and the same expansive clay soil that drives footing requirements across North Texas.
This guide breaks down what a deck actually costs in Allen, what the city requires for permits and HOA approval, and how to tell whether an estimate you've received is fair for the Collin County market.
Deck Cost in Allen by Size and Material
Square footage and material are the two largest cost drivers. Here's a realistic installed range for Allen-area decks, including materials, labor, standard footings, stairs, and basic railing:
| Deck Size | Pressure-Treated | Cedar | Composite (Trex/TimberTech) |
|---|---|---|---|
| 200 sq ft | $10,500–$13,500 | $13,500–$17,500 | $16,500–$22,500 |
| 350 sq ft | $14,500–$19,500 | $19,500–$26,500 | $24,500–$34,500 |
| 500 sq ft | $19,500–$26,500 | $26,500–$36,500 | $33,500–$48,500 |
These figures do not include permit fees, HOA submission costs, electrical for lighting, or removal of an existing structure. Allen's competitive contractor market keeps pricing in line with neighboring Plano and Frisco rather than rural Hunt County rates.
Why Allen Deck Pricing Reflects Clay Soil
Allen sits on the same expansive Blackland Prairie clay as the rest of Collin County. This soil swells 30 to 40 percent when wet and contracts when dry, which means footing depth is not optional. We set deck footings to a minimum of 24 inches in the Allen area, going to 36 inches for elevated or larger decks. Contractors who use shallow 18-inch footings to win a bid leave homeowners with decks that heave and shift within a few years. Proper footings add a few hundred dollars to a build; fixing a footing failure costs many thousands.
Permits and HOA Approval in Allen
The City of Allen requires a building permit for most decks, particularly those over 200 square feet or elevated more than 30 inches above grade. Permit fees generally fall in the $150 to $400 range with a review timeline of roughly 5 to 10 business days. Allen also has a high concentration of HOA communities, and most require Architectural Control Committee approval before any exterior work begins.
HOA review adds two to eight weeks to your timeline, so it pays to start early. We prepare and submit HOA design packets on behalf of our Allen clients and maintain a high first-approval rate because we know what local committees expect to see in a submission.

How to Evaluate an Allen Deck Estimate
When you compare bids, ask three questions before price even enters the conversation: What is the footing depth and diameter? What lumber grade is used for the framing? And is the quote fully itemized, with materials separated from labor? A reputable Allen contractor answers all three without hesitation. The lowest bid is rarely the cheapest deck once you account for early board failure and footing problems.
- —Confirm footing depth in writing (24 inches minimum for Allen clay)
- —Verify framing lumber is ground-contact rated where required
- —Require an itemized quote, not a lump sum
- —Ask whether HOA submission and permits are included
- —Check that the start date is confirmed, not open-ended
