Not every deck needs to sit high off the ground, but in a lot of Florida yards, some amount of elevation is not optional. It depends on the ground itself more than personal preference.
Why Ground Contact Causes Problems Here
Florida’s sandy soil and heavy seasonal rain mean ground level or near ground level decking is far more exposed to standing water and constant moisture than it would be in a drier climate. Wood in direct or near constant contact with damp ground breaks down faster, and even composite materials perform worse over time when they are not allowed proper airflow underneath. Some minimum clearance between the deck framing and the ground is usually required specifically because of this.
What Proper Elevation Actually Looks Like
Beyond just meeting code, proper elevation allows air to circulate underneath the deck, which keeps moisture from building up against the framing and the underside of the boards. It also makes it possible to inspect and maintain the structure underneath over the years, which is much harder with a deck built flush to the ground. The exact height required depends on the yard’s drainage and grading, which is something a contractor should assess before the design is finalized, not after.

What This Means for Design and Planning
This is one of those details that affects the whole project, including whether stairs, railing, and skirting are needed, so it needs to be settled early rather than adjusted after the framing is already built. A deck built without accounting for this in a yard that holds water after rain is one of the more common reasons decks fail early in Florida specifically.
Elevation is one piece of building a deck that actually holds up here. Material choice matters just as much, which is covered on the deck building page.
