What to Expect When Building a Custom Deck in Colorado

So you’re ready to build the outdoor space of your dreams—but what exactly goes into a custom deck build in Denver or across Colorado? From planning and permitting to design and construction, a deck project involves more than just picking out boards. The good news? With the right team and clear expectations, the process can be smooth, exciting, and well worth the investment.

Here’s what Colorado homeowners can expect when building a custom deck—and a few tips to make the experience as stress-free as possible.

The Consultation & Design Phase

Every great deck begins with a conversation. This is where you share your goals, inspiration, and the way you plan to use the space. Do you want a grilling station? A covered area for all-season use? Built-in seating or planter boxes? This is your time to dream big.

What happens during this phase:

• Site visit to assess space, sun exposure, and access
• Measurements and sketches to inform layout
• Discussion of materials (wood decks vs. composite decks) and features
• Budgeting and scope alignment
• Preliminary renderings or mock-ups

At Centennial Custom Decks, we help guide homeowners through each decision to ensure the deck fits the home, the landscape, and your lifestyle.

Permitting and HOA Approvals

One of the most important (and often overlooked) steps in the deck construction process is navigating local building codes and requirements. Colorado municipalities—including Denver and surrounding areas—have specific rules about deck height, railings, snow load, and more.

We handle:

• Submitting permit applications to the city or county
• Coordinating any required inspections
• Managing HOA communication if approvals are needed

Pro Tip: If you’re building in fall or winter, permitting tends to move faster—and you’ll be ready to enjoy the space by spring.

Preparing the Site

Before construction begins, your site is prepared for the build. This may include grading the land, removing old structures, or creating proper drainage paths. In Colorado, soil conditions and slope can impact how the deck’s foundation is designed.

For example, clay-heavy soils (common in Denver) expand and contract with moisture, which may require deeper footings or specific support strategies. Our team builds with these local conditions in mind.

Construction Begins

Once permits are secured and the site is ready, construction gets underway. Depending on the size and complexity of the project, most custom deck builds in Denver take 1–3 weeks to complete.

What’s typically included:

• Installing footings and framing
• Laying decking boards
• Adding railings, stairs, and any special features
• Electrical and lighting installation (if applicable)
• Final inspection and walkthrough

Throughout the process, we prioritize communication, cleanliness, and craftsmanship so your experience stays positive from start to finish.

Enjoy Your Outdoor Upgrade

When construction wraps up, it’s time to enjoy your new favorite space. Whether you're hosting backyard barbecues or sipping your morning coffee with a mountain view, a custom deck adds lasting value and livable space to your home.

And because Colorado weather can be unpredictable, we’ll provide ongoing care and Colorado deck tips for maintenance that keeps your deck looking great through all four seasons.

FAQ: Building a Custom Deck in Colorado

Do I need a permit to build a deck in Denver?
Yes. Most decks—especially those above 30 inches in height—require permits and inspections under local code.

What materials are best for Colorado’s climate?
Composite decking and pressure-treated lumber both perform well in Denver’s freeze-thaw cycles. Composite offers low maintenance, while wood has a classic look.

Can I use my deck year-round in Colorado?
Absolutely! Covered areas, infrared heaters, and smart lighting can turn your deck into a four-season space.

How much does a custom deck typically cost?
Costs vary based on size, materials, and features. Centennial Custom Decks works with all budgets and provides transparent estimates up front.
