If you’re planning to build a deck, one of the first things you’ll need to decide is how high off the ground it will be. This is known as deck height, and it plays a major role in everything from your deck’s structure to safety features, permitting requirements, and even how you’ll access it.
At Arca Construction, we guide homeowners through every step of the design process, including determining the ideal deck height for their home and lifestyle. Let’s take a closer look at what deck height means in construction and why it matters.
Defining Deck Height
Deck height refers to the vertical distance between the ground and the surface of your deck. It’s typically measured from the grade (the natural ground level) to the top of the decking boards.
There are generally three categories of deck height:
- Low-level decks: Up to 30 inches off the ground
- Mid-height decks: Between 30 and 60 inches
- High-level decks: Over 60 inches (5 feet or more)
Each category has its own design considerations and building code requirements, which we'll explore below.
Why Deck Height Matters?
Deck height isn’t just a visual or practical decision—it affects several key aspects of your project:
1. Safety and Railing Requirements
The higher your deck, the more critical safety features become. According to most building codes:
- Any deck over 30 inches above grade requires a guardrail at least 36 inches high.
- Stair railings are also required if your deck has more than a few steps.
At Arca Construction, we always build with code compliance in mind, ensuring your deck is both safe and stylish.
2. Structural Design and Support
Higher decks require stronger framing and support systems. This might include:
- Larger or more numerous support posts
- Deeper footings to handle vertical load
- Lateral bracing to resist sway and movement
Low-level decks, by contrast, may not need posts at all and can often sit on simple concrete blocks or piers.
3. Stairs and Access
Deck height directly affects how you’ll access your deck. Higher decks require:
- Sturdy, well-designed staircases
- Landings or intermediate platforms for long flights
- Lighting for nighttime safety
Mid- and low-height decks may only need a step or two—or none at all if built level with an entryway.
4. Aesthetics and Views
Deck height can dramatically change your outdoor experience:
- Low decks blend more naturally with your landscape. Read more for landscaping ideas around a deck.
- High decks provide elevated views and can feel like a treehouse retreat
- Mid-height decks strike a balance between easy access and improved sightlines
Your home’s architecture and the slope of your yard will help determine what works best.
Choosing the Right Deck Height for Your Home
There’s no one-size-fits-all answer—it depends on:
- The height of the door leading to your deck
- The slope or grade of your backyard
- Whether your deck will be freestanding or attached to the house
- Your personal preference for views, privacy, and accessibility
An experienced contractor like Arca Construction will assess your site, review code requirements, and help design a deck that fits your needs and your property.
