How Do Builders Schedule Trades on a Home Build?

By Wyatt Cooper · Published October 11, 2026 · 5 min read

Key takeaways

A home build follows a fixed order: site and foundation, framing, rough-ins, insulation, drywall, finishes, then final inspections.
The building department's inspections set the gates: work stays uncovered until the inspector approves it, so each inspection is a milestone on the schedule.
Book each trade off the one before it, and confirm the next two or three trades every week rather than handing out dates once at the start.
The rough-in trades (plumbing, HVAC, electrical) overlap; insulation and drywall can't start until all of them and the framing pass.

Builders schedule trades on a home in the order the building and its inspections allow: excavation and footings, foundation, framing, the plumbing, HVAC and electrical rough-ins, insulation, drywall, then interior and exterior finishes and final inspections. Each trade is booked off the one before it, inspections are treated as milestones that must pass before work is covered, and the next few trades are confirmed every week.

The trade sequence, phase by phase

Every jurisdiction words it a little differently, but the order is set by what has to be inspected before it is covered. Alexander County, North Carolina's residential inspection procedures call for footings to be inspected before concrete is poured, and rough-ins to be inspected before any wall or ceiling finish or insulation goes in. The City of Brainerd, Minnesota's list puts it plainly: all work stays uncovered until the city inspector approves it.

A typical trade order on a new single-family home, and the inspection that gates the next step (check your building department's list)
Phase	Trades	Inspection before moving on
Site and footings	Excavator, surveyor, concrete (footings)	Footing: trenches dug, steel in place, before concrete
Foundation	Concrete or masonry, waterproofing, under-slab plumbing	Foundation, under-slab plumbing; damp-proofing before backfill
Framing	Framer, trusses, windows and exterior doors, roofer	Framing (after the rough-ins in many places)
Rough-ins	Plumber, HVAC, electrician, low voltage	Plumbing, mechanical and electrical rough-in
Insulation	Insulation installer	Insulation, before drywall
Drywall	Hanger and finisher	Gypsum board, where fire-rated assemblies need it
Finishes	Cabinets, trim carpenter, painter, flooring, tile, counters, siding, gutters, flatwork	None, usually, until the finals
Trim-outs and finals	Plumber, HVAC and electrician set fixtures and equipment; final clean	Plumbing, mechanical, electrical and building finals, then occupancy

Two things vary by place. Some departments want all rough-ins approved before they will inspect the framing (Brainerd does); others inspect framing first. And some will inspect framing before the permanent roof covering is on (Alexander County says it may or may not be installed by then). Ask your building department for its list before you build the schedule around it.

An example: booking trades off each other

Here is how a builder might lay out the middle of a made-up house, in working days, once the foundation is backfilled. The durations are an illustration for one house, not typical figures.

1FramerWalls, floor and roof framing, sheathing: days 1–10
2Roofer and window installerRoof dried in and windows set: days 11–13
3Plumber, HVAC, electricianRough-ins, overlapping in the same days: days 14–18
4Building departmentRough-in and framing inspections: day 19
5Insulation installerInsulation, then its inspection: days 20–21
6Drywall crewHang and finish: days 22–29

From framing to drywall on a fictional house: each step starts when the one before it is done or inspected

Add it up and the stretch from first wall to finished drywall is 29 working days, about six weeks (10 + 3 + 5 + 1 + 2 + 8 = 29). The chain has no slack: a failed rough-in inspection on day 19 pushes insulation and drywall by however long the fix and the re-inspection take. That chain is the critical path, and it is why builders call the inspector the day before and have the trades on site when they come.

Keeping the trades lined up

Give each sub a start date, then confirm it the week before. Dates handed out once at the start drift by the time the house is framed.
Look three weeks out every week: which trades start, what they need (material, a passed inspection, the trade before them finished). A three-week look-ahead is the habit commercial builders use for this, and our free template works on a house too.
Order long-lead items early: windows, trusses, cabinets and some fixtures can take weeks, and they gate the trades behind them.
Put each inspection on the schedule as its own line, and book it the way the department requires (Brainerd asks for the request the day before).
Walk the house before each trade arrives, so the next crew isn't standing around waiting on the last one.
Finish with a punch list before the final walk-through, not after it.

The bottom line

Schedule a home build in the order the inspections allow, book each trade off the one before it, and confirm the next few every week. The inspections are your milestones; the trades fill the days between them.

Questions

What order do trades go in when building a house?

Excavation and footings, foundation, framing and roofing, then the plumbing, HVAC and electrical rough-ins, insulation, drywall, interior and exterior finishes, and finally the trim-outs and final inspections. Your building department's inspection list sets the exact gates.

Do plumbing, HVAC and electrical rough-in at the same time?

They overlap, but they need an order inside the walls: usually plumbing drains and HVAC ducts first because they are the biggest and least flexible, electrical last. All three must pass inspection before insulation.

When is the framing inspection?

It depends on the jurisdiction. Some inspect framing after the rough-ins have passed; others inspect it first. Check your building department's list.

How far ahead should a builder schedule subcontractors?

Give each a target date early, then confirm the next two or three trades every week. Long-lead material such as windows, trusses and cabinets needs ordering well before the trade arrives.
