Deck collapses are almost never a failure of the deck. They are a failure of the connection between the deck and the house.
In detail
Decks, porches & pergolas
The ledger — the board bolted to the house that carries one entire side of the deck — is where residential decks fail, and it fails in two ways. Structurally, when it is nailed rather than through-bolted or lagged to a proper schedule, so the fasteners work loose under cyclic load. And by rot, when it is fixed over siding with no flashing, so water runs down the wall, sits behind the board and quietly destroys both the ledger and the rim joist behind it. We flash the ledger, bolt it to a specified pattern, and detail the joint so water passes it.
The rest follows from that: footings below the local frost line so nothing heaves, posts on standoff bases so end grain is not sitting in water, joists hung rather than toe-nailed, and guards and handrails built to the code heights and load requirements. Porches and pergolas carry the same logic with a roof on top, which means the connection also has to resist uplift.

Questions
Asked most aboutdecks, porches & pergolas
Do I need a permit to build a deck in New Jersey?
In almost all cases yes, and the inspection sequence usually includes the footings before they are poured and the framing before decking goes down. Decks are also subject to setback and coverage limits like any other structure, so a deck can require zoning relief even when the house does not.
How long should a deck last?
The framing should outlast the surface. Pressure-treated framing on proper footings, kept dry at the connections, lasts decades; the walking surface and rails are the parts that weather and get replaced. If a deck is failing at the ledger or the posts rather than at the boards, it was a detailing problem from the beginning.
