Dreaming of a Backyard Upgrade? Start With the Right Deck Plan
A great backyard starts with a strong and safe deck. If you’re wondering how to build a deck step by step, you’re in the right place. Many homeowners dream of having a space to enjoy the outdoors, host cookouts, or just relax. A deck is a simple way to make that dream come true.
Before you start building, it helps to have a clear plan. This includes thinking about how big your deck should be, what it will be used for, and how it will connect to your home. A good plan makes the rest of the job easier.
Start by looking at your backyard space. Make sure it’s flat or can be leveled. Think about sunlight, wind, and how much privacy you want. Also, check if you’ll need a permit or follow local building codes. That way, you won’t have to stop your project halfway.
What You’ll Need Before You Start Building Your First Deck
Before lifting a hammer, gather the tools and materials you’ll need. You don’t want to keep running to the store in the middle of your project.
Here’s a list to get you started:
- Pressure-treated wood or composite decking
- Joists, posts, and beams
- Deck screws, joist hangers, and concrete for footings
- Circular saw, drill, and tape measure.
- Level, square, and safety gear
Also, decide on the deck height. Ground-level decks are easier to build but might need extra protection from moisture. Raised decks need stairs, railings, and extra support.
Measure your area carefully. Use batter boards and string to outline the space. Mark the spots where posts will go. Check for underground pipes or wires before digging. Planning well now saves time and trouble later.
Understanding Deck Construction Basics: Posts, Joists, and Boards
Every strong deck starts with the right base. Posts go into the ground to hold the frame. Joists stretch across the top and support the boards you walk on. This setup keeps the deck solid and safe.
Use concrete to set your posts in place. Dig holes at least 12 inches deep or until you reach the frost line. Pour in the concrete and let it dry fully before adding weight.
Next, connect the posts with beams. Use joist hangers to attach joists. Joists should be spaced evenly, usually 16 inches apart. This spacing helps your deck stay strong and keeps the boards from bending or cracking.
The top part of the deck is made of boards. You can use natural wood or composite decking. Composite is more expensive but lasts longer and needs less care. Whichever you pick, lay boards across the joists and screw them down tightly.

How to Choose the Right Deck Design for Your Home and Space
Decks come in many shapes and sizes. Some are small with just enough room for a couple of chairs. Others are large and wrap around the house. Your deck design should match your needs and fit your space.
Think about how you’ll use the deck. Will you have guests over? Need space for a grill? Want a quiet place to read? The answers will help guide your design.
A square or rectangular deck is easiest for beginners. L-shaped or curved decks are harder to build and need more skill and planning.
Also, think about your house style. You want the deck to look like it belongs. Match the colors and materials if you can.
Finally, check your yard’s slope. A flat yard works best, but even if your yard isn’t flat, you can still build a raised deck. Just remember, more height means more steps and support.
A Step-by-Step Guide to Laying Out Your Deck Foundation
Now that you have your design and tools, it’s time to mark your space. This part is all about getting the base right.
- Mark the area: Use batter boards and string to outline your deck shape.
- Check for square: Use the 3-4-5 triangle rule or a carpenter’s square.
- Dig post holes: Make them deep enough for your frost line and about 12 inches wide.
- For footings: Mix and pour concrete into each hole. Let it cure for at least 24 hours.
Once the footings are ready, add your post anchors. These metal brackets hold the posts upright and secure. Place the posts, make sure they’re level, and cut to the right height.
Double-check everything before moving on. If your foundation isn’t level, your deck won’t be either.

Framing the Deck: Ledger Boards, Joist Hangers, and Rim Joists Explained
The frame is what gives your deck shape and strength. It connects your posts and supports everything else.
Start by attaching a ledger board to your house. This is a long, strong board that runs the length of the deck. Make sure it’s level and securely fastened. Use lag bolts or strong screws.
Next, attach your rim joists to the outer posts. Rim joists run around the edge of your deck and connect to the ledger. Then, install joists between the ledger and rim joist. These boards run across the middle and hold the deck boards.
Use joist hangers to keep everything in place. Joist hangers are metal brackets that make your frame strong and safe. Space your joists 16 inches apart unless your plans say otherwise.
Once all the joists are up, double-check your work. Make sure everything is square, level, and tight.
How to Install Deck Boards for Long-Term Durability and Safety
Now comes the part you’ll see and walk on — the deck boards. Start from the house and work out toward the yard.
Use deck screws to hold each board in place. Don’t nail them down — screws are stronger and last longer. Leave a small gap between boards (about 1/8 inch) to let water drain.
Check each board as you go. If it’s warped or cracked, don’t use it. Line up your ends neatly, and stagger joints for a better look.
If using composite decking, follow the manufacturer’s instructions. These boards often need hidden clips and have special care rules.
Take your time here. This part makes your deck look good and feel strong.

Building Deck Steps and Stringers the Simple Way
Stairs let you safely step down from your deck to your yard. If your deck is low, you might only need one or two steps. If it’s raised, you’ll need more.
Here’s how to build simple deck steps:
- Measure from the top of the deck to the ground.
- Divide that height by 7 to get the number of steps.
- Cut stringers using a stair gauge and a circular saw.
- Attach the stringers to the deck frame.
- Add treads (the part you step on) and risers (the vertical part).
Use pressure-treated wood or other outdoor-rated materials. Make sure the steps are level and safe.
Building steps might seem tricky, but once you get the hang of it, it’s a fun part of the build.
Adding Railings and Finishing Touches for Style and Stability
If your deck is more than 30 inches off the ground, you’ll need railings. Even if it’s lower, railings help make it safer.
You can buy pre-made rails or build your own. Use strong posts, usually every 6 feet. Attach balusters (vertical rods) every 4 inches. Top it off with a handrail.
Add caps to the posts for a finished look. You can also stain or seal the wood to protect it from rain and sun.
Other finishing touches might include:
- Lighting for night use
- Planter boxes
- Built-in benches
- A canopy or shade sail
These little details turn your deck into a true outdoor room.
Common Mistakes to Avoid When Building Your Deck in Hillsboro, OR
Even skilled DIYers make mistakes. Here are some things to watch out for:
- Not getting a permit
- Skipping local building codes
- Forgetting to slope the deck for water runoff
- Using untreated wood close to the ground
- Not spacing joists or boards correctly.
The weather in Hillsboro, OR, can be damp, so make sure your materials are weather-resistant. Composite decking or pressure-treated lumber can last longer in this climate.

Final Checks and Deck Maintenance Tips to Keep It Looking Great
Before calling your deck finished, give it a full check:
- Are all screws tight?
- Do the railings wiggle?
- Are the stairs safe and sturdy?
- Does water drain off well?
If everything checks out, it’s time to enjoy your new deck. But don’t forget — decks need care. Sweep leaves off often, clean with gentle soap, and re-stain or seal every few years.
Pressure wash once a year if needed, but don’t use too much force. That can damage the wood.
Decks can last 15–30 years with the right care. Treat it well, and it’ll be a favorite part of your home for a long time.
