Footings for ground-level decks need to be at least 12 inches deep, and some areas require them to be even deeper. A standard range for deck footings is anywhere from 12 to 48 inches. The minimum footing depth is determined by an area’s frost line and soil conditions. If you’re unsure how deep to install deck footings, check local building codes to find the minimum footing depth in your area. 

A covered deck can be a good investment that increases your home value—especially if you live in a hot region with a lot of sun. A covering over the deck means you can get more use out of it, even on the hottest summer days. With a permanent deck covering, you can even add ceiling fans to help cool down your deck for added comfort.

Pressure-treated decks last 15 to 20 years on average, but with proper maintenance, you could get 40 to 50 years of value from yours. Reseal your deck every one to two years, and replace old or rotted wood as soon as possible to avoid structural damage. Where you live plays a role in the lifespan of your deck. Intense sunlight, rainfall, wind, and hail can reduce the deck’s lifespan.

In general, you need a footing at each corner of your deck, and within 8 feet of each other. So, how many you need depends on the size and shape of your deck, plus any local building codes. It also depends on factors like the load capacity of your soil and the weight of your deck. You can find a footing calculator online or contact a pro for support.
