When planning to build a deck for your home, several factors need careful consideration, such as the type of wood, the deck’s location, and the construction team. However, one crucial technical aspect that the team here at Deck Guru has noticed is often overlooked is the type of deck footing to install. The right deck footing is vital for ensuring the stability and longevity of your deck.
There are various types of deck footings available, each suited to different uses. Your choice will depend on whether your deck will be attached to your house or standalone, local building codes, and the deck’s size and height.
What Is a Deck Footing?
Deck footing serves as the foundation of your deck, connecting it securely to the ground. Only very small, ground-level decks can forego footings. For larger decks supporting more weight, proper footings are essential for safety and stability.
Why Are Deck Footings Important?
Deck footings prevent your deck from tipping or caving in and keep it elevated and dry, avoiding rot. They are also required by building codes in many areas, including Northern Virginia, ensuring your deck complies with legal regulations and remains safe for use.

Frequently Asked Questions
Deck Footing vs. Foundation
The foundation is the post that transfers the deck’s load to the ground, while the footing is the part in contact with the earth or concrete, providing stability.
Can I install deck footings myself?
Some deck footing types are easy to install yourself. For others that require installation equipment, It’s best to have a professional install deck footings to ensure stability and compliance with local regulations.
What’s the difference between a deck footing and a deck post?
Footings are the concrete parts that touch the ground, while posts are the wooden pieces attached to the footings, supporting the deck.
How Many Footings Do You Need for Your Deck?
The number of footings depends on the deck’s size, design, and load requirements. Generally, footings should be less than eight feet apart.
