You have an idea to build a deck, and you’ve saved up what you think is enough money to make it happen. Now all you have to do is buy the materials and start building, right? Well, there’s actually a lot more to it than that. Designing a deck isn’t just about picking materials and hammering nails—it requires careful planning to avoid costly mistakes that could compromise its safety, functionality, or longevity.

Skipping over critical steps in the design process can lead to regrets down the road, from wasted space to maintenance headaches. To help you avoid these pitfalls, we’re breaking down the five most common deck design mistakes—and how you can steer clear of them. With a bit of preparation and the right guidance, you’ll be on your way to building the perfect deck for your home.

Mistake #1: Ignoring Local Building Codes and Permits

It’s tempting to jump straight into the building, but skipping over local building codes and permits is one of the most common—and costly—mistakes homeowners make. Regulations vary depending on where you live, and they’re in place to ensure your deck is safe and up to standard. From proper railing heights to load-bearing requirements, overlooking these rules can result in hefty fines, failed inspections, or even needing to tear down and rebuild your deck.

How to Avoid It:
Before you start building, research your local building codes or consult with a professional. Many municipalities in Alberta have specific requirements for deck height, setbacks from property lines, and materials used. Partnering with an experienced company like Econo Decks can save you time and stress by ensuring all permits and codes are properly handled.

Mistake #2: Poor Space Planning

Your deck should complement your lifestyle, but poor space planning can lead to an awkward layout that doesn’t meet your needs. Imagine having a beautiful deck that doesn’t have enough room for your patio furniture, or a design that blocks foot traffic during gatherings. These issues can turn your dream outdoor space into a frustrating experience.

How to Avoid It:
Start by considering how you plan to use your deck. Will it be for dining, lounging, or entertaining? Measure your furniture, allow room for pathways, and think about how people will move through the space. A general rule of thumb is to leave at least 3 feet of clearance for walking paths and enough space for all planned activities. Working with a professional designer can also help you create a functional layout that maximizes your deck’s potential.

Mistake #3: Choosing the Wrong Materials

Not all decking materials are created equal, and choosing the wrong ones can lead to maintenance nightmares or a deck that doesn’t hold up to the elements. For example, untreated wood might look great initially but can warp, crack, or rot in Alberta’s harsh climate. Similarly, selecting materials solely based on price often results in higher long-term costs due to frequent repairs or replacements.

How to Avoid It:
Choose materials based on durability, maintenance requirements, and how well they suit your local climate. Composite decking is an excellent option for homeowners looking for low-maintenance and weather-resistant materials, while pressure-treated wood offers an affordable and durable alternative if maintained properly.

Mistake #4: Overlooking Drainage and Ventilation

Poor drainage and ventilation are often overlooked in deck design, but these factors are crucial to the longevity and safety of your deck. Water can pool on your deck without proper drainage, leading to mold, rot, and structural damage. Similarly, inadequate ventilation underneath the deck can trap moisture, accelerating decay and weakening the foundation over time.

How to Avoid It:
Ensure your deck has proper drainage gaps between boards to prevent water from accumulating on the surface. For elevated decks, adequate airflow underneath is essential to minimize moisture buildup. This can be achieved by ensuring enough clearance between the deck and the ground and leaving ventilation openings. If you’re unsure about these details, professionals like Econo Decks can design your deck to account for proper drainage and ventilation from the start.

Mistake #5: Failing to Plan for Future Needs

A deck designed only for your current needs might seem perfect now, but it can quickly feel limiting as your lifestyle changes. For example, a deck that’s too small for growing families, or one that doesn’t account for adding features like a pergola, outdoor kitchen, or hot tub later, may require expensive modifications in the future.

How to Avoid It:
Think long-term when planning your deck. Consider how your needs might evolve over time—whether that’s more space for entertaining, additional seating, or functional upgrades. Opting for a flexible design, such as a multi-level deck or leaving space for future add-ons, can save you money and effort down the road. Working with experienced professionals like Econo Decks ensures that your deck is designed with the future in mind, so it can adapt to your lifestyle as it changes.
