Step 4: Design Your Deck

Designing your deck and its structural components is a critical part of every project. Prior to starting your design, it is important to familiarize yourself with the terminology outlined in the “Meet Your Coach” section of the game plan. Knowing the proper elements of the design will get you closer to completing your project successfully.

This step of the game plan will also help you become familiar with the basic structural requirements that need to be followed when building a deck. Contact your Build-it-Better Coach to set up an appointment.

Frequently Asked Questions:

What is the length and what is the width of my deck?

There is no true definition of length or width for a deck. Typically, people consider the length to be the distance perpendicular to the house and the width to be the distance parallel to the house.

Do joists go perpendicular, parallel or diagonal to the house?

This all depends on the design of your deck and which way you want your deck boards to run. A consultation with a Build-It-Better coach will help determine the answer to this question.

How close to the fence line can a deck be?

A typical answer would be this: If your deck is going to be more than 18 inches above the ground you cannot build the deck within 20 feet of the front property line or within 5 feet of side property lines. This regulation varies by region so always check with your local permit office before building.

What is the highest a deck can be?

Normally a deck cannot be higher than your house. Maximum height restrictions vary by region so check with your local permit office.

How do you map out a deck?

Where should footings be placed?

The placement of footings is another thing that depends on deck design. Typically footings should not be more than 6’6” from each other. Larger beam lumber such as 2×12 can span a further distance if needed.

After you string out your deck size and get a design, it helps to mark footing spacing to get an even better feel for what your deck will be like. This also helps in the execution stage of building a deck when you need to dig holes.

How far can cantilever go on a deck?

Anything over 18” needs to be designed by an engineer. This can vary by region so check with your local permit office.

Do I have to use landscape fabric below my deck?

In some municipalities you are required to use fabric and gravel – we recommend that you check with your local permit office. Even if you are not required to use these materials it can go a long way on lawn and weed maintenance around and under a deck.

Do I need to maintain my deck when it is completed?

Proper maintenance will go a long way in extending the lifespan of your deck. Maintenance should be done approximately every 3-5 years as explained in the “Maintaining Your Deck” section of the deck game plan.
