A deck build looks like one job: dig some holes, put up a frame, lay the boards. In practice it is a handoff between several trades — an excavator or concrete crew for the footings, a framer for the structure, an electrician if lighting is planned, and a decking and railing crew to finish it — and each one depends on the trade before it having finished and, in two places, having passed inspection. Run that handoff out of order and the trade who shows up early either stands around or works over something that has to come back out.
Unlike an interior remodel, a deck's sequencing mistakes are not just expensive — they are the same mistakes that cause the structural failures decks are known for. The order of trades on a deck is not a scheduling convenience; it is the mechanism that makes sure the connections nobody can see once the decking goes down were actually built and verified before they were covered.
On a deck, the order of trades and the safety inspection are the same conversation.
What follows is the correct order of trades for a US deck build, the two inspection hold points that cannot be skipped, the sequencing mistakes that cost the most, and how getting the order right protects both the budget and the structure. The code detail behind each stage — footing depth, ledger fasteners, guard height — is set out in the deck building checklist; this article is where the trade handoffs and timing around that code sit. How that timing plays out on the calendar — permit review, the two inspection waits, and material lead times — is set out in the deck building timeline.
Why the order of trades decides a deck build
Because almost everything that makes a deck safe is buried or covered within a few days of being built. The footings disappear under the posts. The ledger connection and its flashing disappear behind the decking. The joist hangers and lateral-load connectors disappear the moment the boards go down. Once that happens, the only proof any of it was done correctly is the inspection that happened before it was covered — which is why the order of trades on a deck has two hold points that do not exist on most interior rooms.
A framer who pours footings before the plan is finalized, or a decking crew that shows up before the framing inspection has passed, is not just working out of turn — they are removing the one chance to verify the parts of the deck that hold it up. The structural detailing behind every hold point in this sequence is codified in IRC Section R507, and the North American Deck and Railing Association points to the same connections — the ledger and the footings — as the source of most preventable deck failures.
The sequence exists to keep that verification window open until it has actually been used, which is the same discipline that runs through the 12 phases of a home remodel applied to a structure most of which is invisible by the time anyone stands on it.
The correct order of trades for a deck
A US deck build moves through these stages in this order. Each step depends on the one before it, and two of them cannot proceed until an inspector has signed off.
- Permit and plan. The plan — dimensions, footing locations, framing layout, connections — is submitted and approved by the local building department before any trade is booked, because every trade after this one is booked against that approved plan.
- Excavation and footings. The excavation crew digs footings below the local frost line and the concrete is poured, on the site the plan specifies, before any framing material arrives.
- Footing inspection. In most jurisdictions an inspector checks the footing depth and placement before the posts go on top of them, because a shallow or misplaced footing is far cheaper to fix before it is buried under a structure.
- Ledger attachment and flashing. The framer bolts the ledger to the house rim joist with the code-specified fasteners and installs continuous flashing, because every joist, beam, and lateral-load connector that follows attaches to or depends on this connection.
- Framing: posts, beams, joists, and connectors. Posts are set on the inspected footings, beams are sized and installed, joists are hung with rated connectors, and the lateral-load connectors go in — the framer's full scope, none of which can start until the ledger is in place.
- Framing inspection. An inspector verifies the ledger, footings, framing, and connectors before a single decking board is installed, because this is the last moment any of it can be seen.
- Decking installation. Once framing has passed inspection, the decking crew lays the boards, which is the point at which the structural work below becomes permanently covered.
- Guards, stairs, and railing. The railing crew builds guards to the required height and spacing and completes any stairs, which depends on the decking being down to establish the finished walking surface.
- Electrical, lighting, and final trim. Where a deck includes lighting or outlets, the electrician's work is completed and tested against the finished structure, followed by any final trim or fascia.
- Final inspection and close-out. The completed deck is inspected for guards, stairs, and overall compliance, and the permit is closed.

The two inspections that cannot be skipped
Two hold points in the sequence above are not optional scheduling steps — they are the only independent verification that a deck's hidden structure was built correctly, and both happen at the exact moment before the next trade would otherwise cover the work.
The footing inspection happens after the concrete crew finishes and before the framer sets a single post, because a footing poured too shallow or in the wrong location is straightforward to correct while it is exposed and effectively impossible once posts, beams, and joists are built on top of it. The framing inspection happens after the framer completes the ledger, posts, beams, joists, and connectors, and before the decking crew lays a single board — because the ledger connection, the single most common point of catastrophic deck failure, is never visible again once decking covers it. A homeowner or contractor who lets either trade proceed before the inspector has signed off has removed the only check that would have caught a problem while it was still cheap to fix.
No trade starts work that covers another trade's work until an inspector — not the contractor, not the homeowner — has signed off on what's being covered.
Footings before posts. Framing before decking. Every other step in the sequence exists to protect those two moments.
Where homeowners get the deck sequence wrong
Two coordination mistakes account for most deck sequencing failures, and neither is about the quality of any individual trade's work.
Booking the decking crew before the framing inspection is scheduled. Framers and decking installers are often different crews, sometimes from different companies, and a decking crew booked to arrive the day after framing finishes — rather than the day after the framing inspection passes — creates pressure to either delay decking or cover ungraded framing to keep the schedule. The fix is booking the inspection as its own step in the calendar, with the decking crew's start date set after it, not assumed to follow framing directly.
Ordering decking material before the framing plan is finalized. Decking board length, fastener type, and quantity all depend on the final joist layout, and material ordered against a preliminary plan before the framer has finalized spacing can arrive in the wrong lengths or quantities, holding the decking stage while a reorder comes in. Confirming the framing plan before placing the material order keeps the last stage of the sequence from being the one that stalls it.
Both mistakes share the same root cause as most deck problems: treating the sequence as a convenience rather than the mechanism that gets the structure inspected before it disappears. The cost consequences of getting any stage wrong are catalogued in the deck building mistakes that cost US homeowners thousands.
How the order protects the budget and the structure
Running the trades in this order is what keeps a deck on its quoted price and, more importantly, keeps it structurally sound. When the footings are inspected before the posts land on them and the framing is inspected before the decking covers it, every later trade is building on verified work rather than an assumption. Nothing gets covered twice, and nothing gets discovered wrong after it is too expensive to fix.
The Outdoor Renovation Blueprint runs a deck build through The 12-Phase System — Property Blueprint Co.'s framework for taking a homeowner from the first contractor conversation to substantial completion — with the two inspection hold points positioned exactly where the sequence above puts them, so the connections that decide whether a deck stands are verified before they vanish under the next trade's work.

Every trade handoff, every inspection hold point, positioned in the order the work actually has to happen — so the deck is built once, verified, and standing.

Frequently asked questions
What is the correct order of trades for building a deck?
Permit and plan, excavation and footings, footing inspection, ledger attachment and flashing, framing of posts, beams, joists, and connectors, framing inspection, decking installation, guards and stairs, any electrical work, then final inspection and close-out. Each stage depends on the one before it, and the footing and framing stages cannot proceed to the next step until an inspector signs off.
Why are there two inspections during a deck build?
Because a deck's structural work disappears in two stages: the footings disappear under the posts, and the ledger, framing, and connectors disappear under the decking. Each inspection is the last chance to verify that work before it is permanently covered, which is why both happen at the exact point before the next trade would otherwise build over them.
Can the decking crew start before the framing inspection is done?
No. Decking should never be installed until the framing inspection — covering the ledger, footings, framing, and connectors — has passed, because decking permanently covers all of that work. A decking crew scheduled to arrive right after framing finishes, rather than after the inspection passes, is the most common scheduling mistake on a deck build.
Should I order decking material before the framing is finalized?
No. Decking board length, fastener type, and quantity depend on the final joist layout, so material ordered against a preliminary plan can arrive in the wrong lengths or quantities once the framer finalizes spacing. Confirm the framing plan before placing the material order to avoid a reorder holding up the final stage.
Does a homeowner need to be present for the deck inspections?
Not always required, but it is worth attending both if possible. The footing inspection and the framing inspection are the only two moments the structural work behind a deck can be independently verified, and a homeowner who has seen what the inspector checked has a clearer picture of what is actually holding the deck up than one who only sees the finished boards.
