This guide explores the factors influencing deck construction costs and provides insights to help you make informed decisions.
Key Factors Influencing the Cost of a 20×20 Deck
Building a deck largely depends on several variables, including materials, labor, and additional features, contributing to the overall deck building costs. Let’s break down these factors.
Deck costs can vary significantly based on materials, labor, and size.

Material Costs
The type of decking material significantly impacts the overall cost. Below are common materials and their price ranges:
- Pressure-treated wood is a popular and budget-friendly option, costing $15-$25 per square foot installed. While visually appealing and customizable, wood decking generally requires regular maintenance to preserve its quality and appearance.
- Composite Decking Materials: Known for durability and minimal maintenance, composite decking material costs $30-$60 per square foot installed. Despite the higher initial cost, composite decking offers more significant long-term savings due to lower maintenance needs.
- Cedar Wood: Offers a natural look and resistance to insects, priced at $20-$40 per square foot installed.
- Aluminum Decking: Durable and sleek, costing $40-$70 per square foot installed.
- Concrete Decks are ideal for ground-level decks, costing between $10 and $20 per square foot.
Labor Costs
Labor costs vary depending on deck size, complexity, and local rates. In Austin, deck installation labor costs typically range from $10 to $30 per square foot. Labor costs may also increase if the design includes features like stairs, multi-level platforms, or intricate patterns.
Material cost can also significantly impact the overall expenses involved in construction, especially with more intricate designs.

- Custom Features: Unique designs, railings, or lighting systems add to the final price. For example, glass or cable railings can cost significantly more than standard wooden options. Additionally, installation of vinyl or wood railings can range from $20 to $60 per foot.
Local Building Codes

Permits for a deck in Austin can cost $150-$500, depending on your deck’s size and location. Failure to meet code requirements may lead to fines or forced deconstruction, adding unforeseen costs.
Site Preparation
The condition of your yard can influence costs. Uneven terrain or existing structures may require:
- Grading and leveling.
- Additional support structures like concrete blocks or deck posts.
- Remove an old deck or existing landscaping.

A 20×20 deck covers 400 square feet. Based on the material and labor costs mentioned above, here are estimated deck ranges:
- Pressure-Treated Wood Deck: $10,000 – $22,000
