When Is the Best Time to Build a New Deck?
Because the ground is no longer frozen, you can build your deck when it’s warmer outside. Spring and summer have proven to be the best times for outdoor deck building. You may find that builders are more likely to find work during the off-season. But you can plan and design the landscaping around your deck. And that can’t be done when it’s cold outside.
To build the perfect deck in the spring, you need to be prepared for the following:
- Make sure you know where the property line is and how far back you need to go.
- Find pictures of your favorite deck designs online for inspiration.
- Talk to a deck builder or create a building plan yourself.
- In some places, you may need to show a design for your deck to get a building permit.
How Big Can My Deck Be without a Permit?
When we talk about building permits, do you really need one? Pretty sure. The latest International Residential Code states that if the deck is more than 30 inches above the grade next to it, then you always need a permit. Then you will always need a permit. If the deck is less than 30 inches, it is no more than 200 square feet. and it is not attached to the home or used for egress as required by the home, it is exempt. Because of these very specific regulations, most decks require a permit.
Calling your local building department is the only way to be certain. Building without a permit can lead to fines ($500–$5,000+), stop-work orders, or forced removal of the deck. If this happens to the workers you hire, they could lose their license.
Natural Wood vs. Composite Decking: 2026 Comparison
| Feature | Pressure-Treated Wood / Cedar | Composite (Trex, Fiberon, etc.) |
|---|---|---|
| Material Cost (per sq ft) | $3–$10 | About $5–$18 (brand and line dependent) |
| Installed Cost (per sq ft) | $20–$40 | $30–$60 (some premium systems higher) |
| Lifespan | About 10–20 years with regular maintenance | Often 25–30+ years with proper installation |
| Maintenance | Stain/seal every 2–3 years | No staining; wash 1–2 times a year |
| Warranty | 1–5 years (if any) | Commonly 25-year or longer limited warranties |
| Resale Value Boost | Moderate | Often highlighted by real estate agents and buyers |
2026 Real-World Insight: Composite decking now costs only 30-50% more upfront. However, it saves $2,000–$4,000 in maintenance over 10 years. If you plan to sell your home within five years, composite often attracts higher offers.

Developing a Deck Design
Some people have a clear idea of what they want in a deck. They have a very clear idea of how the deck will be built and what materials they want to use. If you don’t know how to design a deck, then you can demand the help of a professional.
You can initially determine your needs by looking at the following aspects and then think further about the deck you want.
Use and Practicality
First, you need to think about how you wish to use and enjoy your outdoor living area. For example, if you wish to have cocktail parties in the evening with friends and family. Then you may want to consider a railing with built-in wine racks or a deck with numerous low-voltage lighting options.
If the deck is built to encourage intimate, cozy conversation. Then it’s best to include natural locations in the design where small groups of people can gather and chat.
Deck Colors
Composite decks come in a variety of colors and wood grain finishes. However, if you choose solid wood, you may have to guess which kind of wood it is. Many people choose pressure-treated wood or cedar, but there are other options to look at and consider. Whether you choose natural wood or composite decking. It’s best to view real samples in real sunlight rather than choosing from a catalog or online.
Extras
Do-it-yourselfers sometimes overlook small but important details. And these details can make a big difference when the deck is being used. Small but important choices can end up making a big difference for you and your guests. Such as railings, lighting, fixtures, benches, hardware, and other items that can be seen.
Do It Yourself or Hire a Professional?
Building a deck is within reach for skilled DIYers. But it’s a structural project that must be safe and code-compliant.
You should strongly consider hiring a professional if:
- The deck is larger than about 200 sq ft or significantly elevated (around 30 inches or more off the ground).
- The deck will be attached to your house, especially near doors, existing siding, or cantilevered floors.
- You are switching from wood to composite and are not familiar with hidden fasteners, specialty hardware, or manufacturer-specific expansion and ventilation requirements.
- You do not have enough time, tools, or carpentry experience to handle layout, framing, flashing, and inspections.
Professionals typically handle permits, inspections, structural engineering (if needed), material delivery, and workmanship warranties, which can save you time and reduce risk.
Is It Cheaper to Build My Own Deck?
A simple, ground-level wood deck may cost around $8–$15 per square foot in materials. It depends on lumber grade, fasteners, and local prices.
A professional installation usually costs $30–$60 per square foot in total for similar projects, with more complex designs and premium materials at the upper end.
That implies you may save about 50–65% of the labor cost by doing it yourself. But problems with the construction, flashing, footings, or stairs could cost you a lot of money and make the project unsafe.
How Much Does It Cost to Build a 20’x20′ Deck?
In 2026, the cost range for a professionally built 20-foot by 20-foot deck is approximately $10,000 to $24,000, or about $40 to $60 per square foot. It depends on whether you choose basic wood or an upgraded composite system with railings and lighting.
2026 Cost Examples (Approximate Ranges)
- 12′ x 12′ wood deck: DIY materials are around $650–$1,000. Professional installation totals $4,500–$7,500.
- 16′ x 16′ composite deck: Professional installation frequently totals about $10,000–$18,000, depending on brand, railing, and site conditions.
- 20′ x 20′ deck: An installed deck costs $10,000–$24,000. Wood is on the lower end, while composite with a railing and lighting is on the higher end.
Plan to add 10-20% for extras like benches, lighting, or stairs. Costs also vary by 20-40% depending on your region, so be sure to get three local quotes.

Inspect Your Existing Deck This Spring
The U.S. is estimated to have over 60 million residential decks. The North American Deck and Railing Association (NADRA) has long estimated that roughly 30 million of those decks are past their useful life and need repairs or full replacement. 10-Point NADRA Deck Inspection Checklist:
- Check for rot or soft spots in posts, beams, and joists by probing with a screwdriver.
- Check the ledger board (where the deck meets the house) carefully for the right flashing, secure fasteners, and evidence of water damage.
- If you have any loose nails or screws, tighten them up. You could also want to upgrade important connections to structural screws or bolts, especially at ledger connections and joist hangers.
- Inspect all hardware (joist hangers, bolts, brackets) for rust, corrosion, or missing fasteners.
- Verify the railing strength. It should be able to withstand a 200-pound concentrated force at the top rail without loosening or failing.
- Check that baluster spacing meets current code. And often no more than a 4-inch sphere can pass through the openings.
- Look for mold, mildew, or standing water on and around the deck that can accelerate decay.
- Examine stairs for solid connections, consistent riser heights, secure treads, and graspable handrails where required.
- Note any movement, excessive bounce, or “spongy” feel when walking across the deck.
- Look for cracks, splits, or severe weathering in structural members, not just decking boards.
Promptly addressing identified issues helps extend the service life of the deck and enhance safety. Unsafe decks cause thousands of injuries every year, and many collapses might have been avoided with regular maintenance and renovations.
