Planning for a New Deck

Check with your local building department and homeowner's association regarding permits and building requirements. Note what elements of the project require inspection and plan your work accordingly.

Decking Materials

Pressure-treated lumber (top right) is the standard material to withstand weather. Most pressure-treated lumber is wet when delivered directly from the store, so you’ll need to let it dry before staining — typically for six months. As an alternative, consider upgrading the decking and railings with composite materials (bottom right).

Marking the Deck Layout

When you have a solid plan, you can mark the layout with strings and batter boards made from 2-foot furring strips and screws. See Making and Using Batter Boards assembly instructions.

Working With Pressure-Treated Lumber

Use fasteners and hardware labeled for treated lumber — stainless-steel or hot-dipped, galvanized screws.

Next Steps

The next stage of the project includes setting the posts and building the framing. See How to Build a Deck: Post Holes and Framing.

Things to Consider When Planning a Deck

A beautifully planned deck is an extension of your home's living space. Before you begin planning, gather inspirational photos, learn your local codes, requirements and restrictions, including those of your homeowners association (HOA), and set a reasonable budget.

Labor

It’s important to consider whether or not this is a viable DIY project or one best left to the pros. Some hidden costs and construction challenges might surprise you. When drafting your plan, check your work with a building inspector to ensure you have enough supports for the size of your deck and that your railings are up to code.

Decking Material Options

Some materials enable customizable design options, from curves to multiple colors and woodgrain patterns, while others are more limited in scope. When choosing a material for your project, keep your priorities in mind: Are you looking for great design options, the best value or maybe a product that offers a balance of both?

Deck Maintenance

Yearly deck maintenance is necessary. Check for loose, split or damaged areas and repair as needed. Depending on your decking material, hose clean or pressure wash to remove grime and mildew growth. Re-stain and seal as recommended by your product's manufacturer.

Can you use a notched stair jack on a deck?

Simple notched stair jacks are fine for interior stairs. They get nailed to wall studs for stability and are hidden once the house is finished. Not so with deck stairs.
