Modular Homes in Caledon, Ontario
Factory-direct modular homes and backyard suites for the Town of Caledon — Bolton, Caledon East, Mayfield West, Inglewood, and the rural villages. Important: Caledon permits a detached garden suite as-of-right ONLY on lots with full municipal water AND sewer — i.e. the serviced settlement areas. On the rural, Greenbelt, and Oak Ridges Moraine majority of Caledon (private well & septic), a detached garden suite isn't as-of-right. Here's what the by-law allows, and the honest catch on servicing.
What you can build in Caledon
Full modular homes — from $175,696. 29 models from 560 to 1,405 sq ft, 1–3 bedrooms — factory-built to the Ontario Building Code and set on a permanent foundation (a real, permanent house, not a “trailer”).
Backyard suites (ADUs) — from $96,244. 7 compact models built for garden-suite and in-law-suite use, sized to fit what Caledon's by-law allows.
All homes are CSA-certified (A277 modular / Z240MH manufactured), finished in the factory, and delivered ready for foundation and hook-up. What's the difference between modular, manufactured, and mobile? →

Caledon modular homes — FAQ
Can you build a garden suite on a rural Caledon lot (well & septic)?
Not as-of-right. Caledon’s ARU overlay (By-law 2023-058) only permits a detached garden suite on a fully-serviced lot — municipal water + sewer — in a settlement area. On the rural, Greenbelt, or Oak Ridges Moraine majority of the Town, a detached suite isn’t as-of-right; the provincial ARU right may still help, so it’s worth a conversation with the Town and us.
How big can a garden suite be in Bolton or Caledon East?
On a serviced lot, up to 75 m² (≈807 sq ft), 4.5 m tall, set back 1.5 m from the side and 2.5 m from the rear, and 3 m from the main house. Check your address to confirm it’s in a serviced area.
Can you put a modular home in Caledon?
Yes. On land you own, a modular home on a permanent foundation is legal residential housing under the Ontario Building Code throughout Caledon, subject to standard zoning and permits.
How much does a modular home or backyard suite cost in Caledon?
Modular home models start at $175,696 and run to about $338,000 for the largest layouts; backyard ADU models start at $96,244. Site work, foundation, delivery, and permits are additional.
Can I get a mortgage on a modular home in Caledon?
Yes — on a permanent foundation it is financed as real property, including via CMHC Prefab Plus (5% down on the first $500,000).
