The realistic build schedule
Most wood-frame houses take seven to twelve months from permit application to certificate of occupancy, and that range is not a guess — it is the sum of phases with known durations. Plan review alone runs 2–10 weeks, framing a 2,000 sq ft shell takes a crew 2–4 weeks, and every phase ends at an inspection that must pass before the next one starts.
| Build stage | Typical time or size |
|---|---|
| Permit plan review | 2–10 weeks |
| Foundation forms stripped | 24–48 hours after pouring |
| Concrete strength test | 28 days |
| Framing, 2,000 sq ft house | 2–4 weeks |
| Stud / truss spacing | 16 in / 24 in on centre |
| Drywall finishing | 3 coats, ~24 h apart |
| Warranty terms | 12 months / 10 years |
A realistic total is seven to twelve months, built up phase by phase — never quoted as one number.
A build schedule is a chain, not a list. Each phase has a typical duration and a hard gate at the end — an inspection, a test result, or a sign-off — and the next trade cannot start until that gate opens. That is why realistic schedules are quoted as ranges with phase dates, not as a single move-in day.
The biggest single block is often not construction at all. Building-permit plan review commonly takes 2–10 weeks depending on the jurisdiction, and lots in flood or historic zones land at the long end because extra reviewers see the plans.
Once the permit issues, the physical build of a typical wood-frame house runs roughly five to eight months: foundation, framing, rough-ins, drywall, finishes, and the final inspection sequence. Weather, correction cycles, and material lead times decide where inside that range a given project lands.
Boundaries shift with jurisdiction, weather, and correction cycles; the order of the gates does not.
Nothing physical starts until the building department finishes plan review, and the review clock runs only on a complete application.
Plan review commonly takes 2–10 weeks. The spread is jurisdiction: a small county office may turn a simple house in two weeks, while a large city routes the set through building, zoning, energy, and stormwater reviewers in sequence. Flood-zone and historic-district lots add specialized review and reliably sit at the long end.
Most applications do not pass on the first submission. Reviewers issue correction comments — missing shear-wall details, undersized headers, incomplete energy forms — and each resubmittal goes back into the queue, adding days or weeks per cycle.
The practical move is to treat review as a phase with its own schedule: submit a complete set, answer corrections within days, and book the excavation crew for the week after expected issuance rather than the week after submission.
Concrete is stripped in 24–48 hours but proven at 28 days; the frame above it takes a crew 2–4 weeks.
Foundation concrete is usually stripped of forms 24–48 hours after pouring, and backfill follows shortly after. Design strength, though, is verified on lab-cured cylinders crushed at 28 days to ASTM C39 — a paperwork gate that runs in parallel with construction instead of holding it up.
Framing a 2,000 sq ft (186 m2) wood-frame house typically takes a crew 2–4 weeks before mechanical rough-ins start. Load-bearing studs go in 16 in (400 mm) on centre, roof trusses commonly sit 24 in (600 mm) on centre, and sheathing, windows, and roofing follow directly behind the frame.
These two phases lock in the geometry every later inspection checks. Habitable rooms must finish at 7 ft (2.1 m) ceilings — sloped ceilings may drop to 6 ft 8 in over half the floor — and bedroom windows are roughed to open to at least 5.7 sq ft (0.53 m2) with sills no higher than 44 in (1,120 mm).
| Build stage | Typical time or size | What it means in practice |
|---|---|---|
| Permit plan review | 2–10 weeks | Longer where the lot sits in a flood or historic zone |
| Foundation forms stripped | 24–48 hours after pouring | Work continues while strength keeps building |
| Concrete strength test | 28 days | Lab-cured cylinders crushed to ASTM C39 confirm design strength |
| Framing, 2,000 sq ft house | 2–4 weeks | Shell complete before mechanical rough-ins begin |
| Stud / truss spacing | 16 in / 24 in on centre | 400 mm for load-bearing studs; 600 mm for common roof trusses |
| Drywall finishing | 3 coats, ~24 h apart | Three drying days before paint or texture |
| Warranty terms | 12 months / 10 years | Workmanship coverage versus structural coverage |
