The Order of Work on a Residential Deck Build
|
What this covers
|
A residential deck goes together in a fixed sequence. Each stage depends on the one before it, and several of them end with an inspection that has to pass before work can continue. Understanding that sequence explains most of what homeowners notice during a build: days when nothing seems to happen, days when the yard fills with lumber, and why the final boards go down so quickly at the end.
This is a walk through that order, stage by stage, for a typical attached deck.
Stage One: Layout and Site Preparation
Every deck starts on the ground. The outline is marked, the height is set against the door threshold, and the locations of footings are measured and staked. Utilities are located before any digging. In Washington that means calling the one-call locate service ahead of excavation.
Site preparation may include removing an old deck, clearing vegetation and setting up a route for materials. Demolition of an old deck is often quicker than people expect and also more revealing, because it exposes the house wall where the old ledger was attached. Any rot found there has to be repaired before the new deck goes up. Access matters more than people expect. Lumber and concrete have to reach the back yard, and a narrow side yard or a fence can slow every delivery for the rest of the job.
Stage Two: Footings
Footings carry the whole structure into the ground. Holes are dug to the depth required by the design and the soil, and in this region frost depth and soil conditions both play a part.
The hole is inspected before concrete goes in. That inspection exists because nobody will see the bottom of that hole again. If the soil is soft or the depth is short, the time to find out is before the pour.

Stage Three: The Ledger and the House Connection
On an attached deck, a ledger board fastens the deck to the house. This is the connection most associated with deck failures nationally, and it is the one inspectors look at closely.
A correct ledger is bolted or lagged into solid framing, not just siding, and it is flashed so water runs past the joint rather than into the house wall. Water getting behind a ledger rots the house framing slowly and invisibly, which is why flashing details matter as much as fasteners.
Freestanding decks skip the ledger and use a second beam instead, which changes the design and sometimes the permit path.
Stage Four: Posts, Beams and Joists
Once footings have cured, posts go up and beams sit on top of them. Beams carry the joists, and joists carry the decking. This is the stage where the deck suddenly takes shape and where most of the carpentry hours go.
Framing details that matter here include:
-
Joist spacing appropriate for the decking material chosen.
-
Hangers and connectors that are rated for the load and for treated lumber.
-
Lateral load connections that tie the deck to the house.
-
Blocking where boards will meet, where heavy items will sit, or where railings will attach.
Composite decking often calls for closer joist spacing than wood, so the decking choice has to be settled before framing starts. Changing the decking after the frame is built can mean adding joists. Good deck framing work accounts for those details before the first joist goes in.
Stage Five: The Framing Inspection
With the frame complete and uncovered, the city inspects it. The inspector looks at the ledger, the connectors, the beam and post connections, spans and lateral ties, all of which are about to disappear under boards.
This is often the point where a project waits. The crew may be ready to lay decking the next morning, but the inspection has to be scheduled and passed first. It is the second major pause in the sequence after the footing inspection.
Stage Six: Decking
Decking goes down quickly compared with framing. Boards are cut, spaced and fastened according to the material’s requirements. Wood is usually face screwed. Composite and PVC boards commonly use hidden fastener systems that clip into the board edges.
The layout of seams, borders and picture framing is decided here. Picture framing, a border board that runs around the perimeter, gives the edge a finished look and hides cut board ends. It also takes extra framing underneath, which is another reason decisions about appearance belong before the frame is built.
Board spacing is the other detail that matters at this stage. Wood boards shrink and swell with moisture, and composite boards expand and contract with temperature. Each material has its own gapping rule, set by the manufacturer for composites and by the moisture content of the lumber for wood. Gaps that are too tight trap water and debris. Gaps that are too wide catch heels and chair legs. In a wet climate the gaps also matter for drainage, because water that cannot get through the decking sits on top of the boards and on top of the joists below.
Many builders also apply joist tape to the tops of the joists before decking goes on. The tape sheds water off the top edge of the framing, where fasteners penetrate and moisture tends to collect, which helps the frame last as long as the boards above it.
Stage Seven: Rails, Stairs and Final Details
Guards are required on deck edges above a certain height, and in the residential code that threshold is 30 inches above the grade below. Railing posts need solid attachment to the frame, because a guard is only as strong as its connection.

Stairs are deceptively complex. They are quoted as a single item and built as several, with stringers, treads, risers and often a landing.
Stage Eight: Final Inspection and Closeout
The final inspection confirms the finished deck matches the approved plan. Once it passes, the permit closes. That closure matters later, because an unpermitted or unclosed deck can surface during a home sale.
Closeout also includes the practical handover. Leftover materials are removed, the yard is cleaned up, and the homeowner should receive information about the decking and railing products used, including any warranty registration and care instructions. Keeping that paperwork with the house records makes future repairs and a future sale simpler.
Where Delays Usually Come From
Delays on a deck build tend to come from the same small set of causes, and most of them sit outside the crew’s control.
-
Inspection scheduling. Two inspections stop work, and each one has to be booked.
-
Concrete cure time. Footings need to set before posts carry load.
-
Material arrival. A specific decking color or railing system that has to be ordered can hold the start or the finish.
-
Weather. Rain affects footing excavation, concrete placement and any finish applied to wood.
-
Changes mid-build. A homeowner who decides on a different stair location or adds lighting after framing is complete creates rework, and sometimes a plan revision.
Of those, changes mid-build are the one the homeowner fully controls. Settling the design before construction begins removes the most avoidable source of delay.
What Homeowners Can Do During the Build
There is not much for a homeowner to do during construction, but a few things help. Keeping pets and children away from the work area protects everyone. Making sure the crew has a clear route for materials avoids daily friction. Being available to answer questions quickly, especially about details like lighting placement before decking goes down, keeps the work moving.
Why the Sequence Sets the Schedule
The order explains why the schedule is longer than the carpentry. Two inspections stop work, concrete has to cure, and materials have to arrive. A useful breakdown of how long it takes to build a deck in Kent shows how those waits stack up in a real permit environment.
For the builder’s location and hours, the listing on Google Maps is current. Knowing the order of work makes it much easier to read a schedule and to tell a normal pause from a real delay.
