Modular home questions, answered straight.
The questions Ontario buyers actually ask us — about cost, financing, HST, permits, foundations, resale, ADUs, and the modular-vs-manufactured difference. Each answer links to the full guide if you want the detail.
Modular home basics
What Is a Modular Home in Ontario?
A modular home in Ontario is a factory-built home constructed to the Ontario Building Code (OBC) on a permanent foundation. The formal CSA standard for modular construction is A277. A closely related category, CSA Z240MH manufactured housing, also ships from a factory and sits on a permanent foundation — and is accepted under OBC Part 9.1.1.9. Both are legally residential housing. They differ in lender treatment and registry path, not in build quality.
Modular Home vs. Manufactured Home in Ontario: What Is the Difference?
CSA A277 modular and CSA Z240MH manufactured are both factory-built, OBC-compliant, year-round residential housing on permanent foundations. The difference shows up in three places: A277 is treated as real property and standard residential mortgage from day one, while Z240MH starts on the Manufactured Home Registry, finances through specialty manufactured-housing lenders or Big 6 manufactured-housing programmes, and can be deregistered to real property after closing. CSA Z241 park models and RVs are a separate category — not year-round residential housing.
Do You Need Land to Buy a Modular Home in Ontario?
You need somewhere to put it — but you have three options in Ontario: buy land first, buy land and home together, or lease land in a 55+ community. Land-lease is the most affordable entry point, averaging $400–$700/month in rent.
Modular and Manufactured Home Builders in Ontario (2026)
Ontario's leading factory-built home manufacturers include General Coach (Hensall, ON — CSA Z240MH Parkland Series), NRB Inc.

ModularHomes400.com's primary supply partner is the General Coach Parkland Series, with 12–20 week lead times from order to delivery.
Do Modular Homes Hold Their Value in Ontario?
Yes — CSA-certified factory-built homes on permanent foundations track local market values like comparable site-built homes in Ontario. MPAC assesses them on the same methodology. CSA A277 modular sells through the MLS exactly like a site-built home from day one. CSA Z240MH manufactured starts on the Manufactured Home Registry and can be deregistered to real property after closing, at which point resale behaviour aligns with the local site-built market.
Buying, renting & investing
How Much Does a Modular Home Cost in Ontario? (2026)
A modular home in Ontario costs $180,000 to $380,000 fully installed in 2026, with most buyers spending $220,000–$280,000 for a 3-bedroom home on their own land. Prices vary by size, finish level, foundation type, and site conditions.
Resale Modular Homes in Ontario: How to Find and Buy a Used Modular Home
Yes — you can buy a resale (used) modular or manufactured home in Ontario. Inventory is limited and rarely reaches the big national portals; most resale modular homes trade through the MLS and modular-savvy REALTORS®. We surface current Ontario listings and represent you on the purchase.
Modular Home as a Rental Investment in Ontario: The ARU ROI Case
A modular home purchased as an Additional Residential Unit (ARU) in Ontario can deliver over 30% annualized ROI on a $19,500 down payment. With a $155,000 home, $40,000 in site costs, and affordable rent of $1,733/month, the 5-year total return is approximately $56,000 — a 287% return on cash invested.
Modular Garden Suites in Ontario: What They Are and How to Build One
A modular garden suite is a detached CSA A277-certified dwelling placed in a backyard on a permanent foundation. In Ontario, garden suites are exempt from development charges, can be built in 4–6 months, and are available from $155,000. They can generate $1,700–$2,000/month in rental income.
Should You Buy a Modular Home as a Rental in Ontario?
Buying a modular home as a rental works strongest as an ADU on land you already own — Bill 23 waives dev charges, financing is HELOC-deductible, and 5-year ROI typically lands at 60–100% of cash invested. Standalone purchases and cottage multi-units are scenario-dependent.
Renting Out a Modular Home or ADU in Ontario: A Landlord's Starting Guide
Renting out a modular home or ADU in Ontario means following the Residential Tenancies Act: use the mandatory Ontario standard lease, collect only a last-month-rent deposit, raise rent once every 12 months with 90 days' written notice, and evict only through the Landlord and Tenant Board.
Building & process
What Permits Do You Need for a Modular Home in Ontario?
A factory-built home in Ontario requires a municipal building permit, typically costing $2,000–$8,000. CSA factory certification — A277 for modular, Z240MH for manufactured — replaces most site inspection requirements. Modular Homes 400 provides all required documentation to support your permit application.
How Long Does It Take to Build a Modular Home in Ontario?
A modular home in Ontario takes 4–6 months from contract signing to occupancy. Factory production (6–12 weeks) runs simultaneously with site preparation, making modular 30–50% faster than comparable site-built construction.
Modular Home Foundation Types in Ontario: Basement, Crawlspace, or Slab?
Ontario modular homes are placed on one of three foundations: full basement ($30,000–$65,000), crawlspace ($18,000–$35,000), or concrete slab ($12,000–$25,000). Basements add the most living space and resale value; slabs are fastest and cheapest.
Modular Home Build Timeline in Ontario: From Contract to Move-In
A modular home in Ontario takes 4–7 months from contract to occupancy: permit approval (4–8 weeks), factory build (12–16 weeks, runs concurrently with site prep), delivery and crane-set (1–3 days), finishing and inspections (4–6 weeks).
Financing, mortgages & HST
Can You Get a Mortgage on a Modular Home in Ontario?
Yes — but the lender path differs by CSA standard. CSA A277 modular homes on permanent foundations qualify for standard residential mortgages from all major Canadian banks (RBC, TD, Scotiabank, BMO, CIBC, National Bank) with CMHC insurance available. CSA Z240MH manufactured homes — including the Parkland Series catalogue Modular Homes 400 sells today — finance through specialty manufactured-housing lenders (Equitable Bank, certain credit unions), or Schedule A bank manufactured-housing programmes. Once the home is deregistered from the Manufactured Home Registry to real-property title, the buyer can refinance into a standard residential mortgage at conventional rates.
CMHC Prefab Plus: How to Finance a Modular or Prefab Home in Ontario
Yes. A modular or prefabricated home on a permanent foundation can be financed with an insured mortgage through CMHC Prefab Plus — 5% down on the first $500,000 (then 10% on the rest), up to 95% financing, with construction funds released in up to four stages.
HST Rebate on a New Modular Home in Ontario: How Much Can You Get?
Ontario buyers of a new factory-built home can receive up to $24,000 in combined HST rebates — a federal New Housing Rebate (up to $6,300 for homes under $450,000) plus an Ontario New Housing Rebate. The home must be your primary residence. Both CSA A277 modular and CSA Z240MH manufactured homes qualify.
Home Insurance for a Modular Home in Ontario: What You Need to Know
A CSA-certified factory-built home — A277 modular or Z240MH manufactured — on a permanent foundation qualifies for standard Ontario home insurance, the same as any site-built home. You do not need specialty mobile home insurance. Premiums typically run $900–$1,800/year depending on location and coverage.
How to Finance a Modular Home in Ontario: All Your Options
The right financing product depends on which CSA standard your factory-built home carries. CSA A277 modular on owned land finances through standard residential mortgages, construction mortgages (during the build), or CMHC-insured mortgages (minimum 5% down). CSA Z240MH manufactured — including the Parkland Series catalogue — finances through manufactured-housing mortgage programmes from specialty lenders or Big 6 banks until deregistered to real property, at which point a standard residential refinance is available. Construction draws are released in stages tied to build milestones either way.
