Quick Answer
A modular home in Ontario takes 4–7 months from contract to occupancy. Permit approval (4–8 weeks) and the factory build (12–16 weeks) run at the same time as site preparation; delivery and crane-set take 1–3 days, and finishing plus final inspections take 4–6 weeks before the occupancy permit.
The Complete Timeline
What makes modular faster than site-built is the parallel process — your home is being built in the factory while your site is being prepared simultaneously.
Phase 1: Contract and Design (Weeks 1–4)
Sign purchase agreement, select floor plan and finishes. Manufacturer confirms order.
Phase 2: Permits (Weeks 2–10, parallel)
Dealer submits permit application to your municipality. Municipal review: 4–8 weeks. Permit issued — foundation contractor engaged.
Phase 3: Factory Build (Weeks 4–20, parallel)
General Coach begins construction while permits process. Typical factory build time: 12–16 weeks. Third-party CSA inspector (Z240MH or A277 depending on the model) present throughout — every module inspected at the factory before it leaves the plant.
Phase 4: Site Preparation (Weeks 8–16, parallel)
Site clearing, foundation construction (3–5 weeks), utility rough-ins. Running concurrently with factory build.
Phase 5: Delivery and Crane-Set (1–3 Days)
Modules transported and lifted onto foundation by crane. Typically 2–4 loads per home. Modules bolted together and sealed.
Phase 6: Finishing (Weeks 4–6)
Mechanical, electrical, plumbing connections. Interior finishing, exterior work, deck and steps.
Phase 7: Occupancy Permit
Final inspection, occupancy permit issued, keys handed over. Total: typically 20–28 weeks (5–7 months) from contract.
What Causes Delays
| Delay Source | Typical Impact |
|---|---|
| Permit processing | 2–8 weeks added |
| Change orders | 1–4 weeks added |
| Foundation issues (soil) | 1–3 weeks added |
| Utility installation | 2–6 weeks added |
| Winter weather (site work) | 1–4 weeks added |
vs. Site-Built
| Build Type | Typical Timeline |
|---|---|
| Modular (Ontario) | 5–7 months |
| Site-built (GTA) | 12–24 months |
| Site-built (rural Ontario) | 10–18 months |
Frequently Asked Questions
Can I move into a modular home in winter in Ontario?
Yes — the home is factory-built in a climate-controlled environment so winter weather does not affect the home build. Site work is slower in winter. Plan for a spring or summer move-in if possible.
What is the fastest a modular home can be completed in Ontario?
Under ideal conditions — pre-approved lots with existing services — a modular home can be completed in as little as 16–18 weeks from contract. 20–28 weeks is more typical.
Does the timeline change for a 55+ community?
Yes — in a land-lease community the servicing is done before any home arrives: roads, utilities and foundation pads are already in. That compresses your timeline to primarily the factory build period plus finishing.
How long does it take to get a building permit for a modular home in Ontario?
Municipal review for a modular home building permit in Ontario typically takes 4–8 weeks. This permit phase runs in parallel with the factory build rather than adding to the schedule, so it doesn't extend the overall timeline. Once the permit is issued, the foundation contractor is engaged, and the factory build itself typically takes 12–16 weeks, with the full project totaling 20–28 weeks (5–7 months) from contract.
