Frequently Asked Questions
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 is built in sections in a climate-controlled factory, then assembled on a permanent foundation and finished to the Ontario Building Code — legally the same year-round housing as site-built. CSA A277 certifies modular construction; CSA Z240MH manufactured homes are also OBC-accepted. Factory construction takes 6–12 weeks; Parkland Series plans start at $176,000 factory-direct, before delivery and installation.
Modular Home vs. Manufactured Home in Ontario: What Is the Difference?
CSA A277 modular and CSA Z240MH manufactured homes are both factory-built, OBC-compliant, year-round housing on permanent foundations — the difference is legal, not structural. A277 is real property with a standard mortgage from day one; Z240MH starts on the Manufactured Home Registry and can be deregistered to real property, typically within 12 months.
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. (CSA A277 modular, residential and commercial), and Triple M Housing (Alberta, CSA A277). 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 — a CSA-certified factory-built home on a permanent foundation tracks its local market like a comparable site-built house, and MPAC assesses it on the same methodology. CSA A277 modular sells through the MLS like site-built from day one; CSA Z240MH manufactured can be deregistered to real property after closing, after which resale behaviour aligns with the local market.
How Long Does a Modular Home Last in Ontario?
A modular home on a permanent foundation lasts as long as a comparable site-built house — decades, with normal maintenance. It is built to the same Ontario Building Code, inspected at every stage in the factory, and engineered for local snow loads and frost depth.
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. The foundation is the biggest variable — from a $12,000 slab to a $110,000 finished basement (General Coach homes, which we sell, sit on a slab, pad or piers) — and prices vary by size, finish level, and site conditions.
What to Ask Before You Buy a Cheap Backyard Cabin Online
Before buying a cheap backyard cabin online, ask eight things: the CSA label, who pulls the permit, ESA-certified electrical, effective R-value, anchoring below the frost line, delivery and crane access, the warranty holder, and the all-in installed price. In Ontario, any cabin over 10 m² (about 108 sq ft) needs a building permit.
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®. Modular Homes 400 surfaces current Ontario listings and represents 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 at the same time as site preparation and permit approval (4–16 weeks), so the total usually depends on your municipality's permit turnaround. The parallel process makes modular 30–50% faster than comparable site-built construction.
Modular Home Foundation Types in Ontario: Basement, Crawlspace, or Slab?
Ontario modular homes sit on one of three foundations: a full basement ($30,000–$65,000), a crawlspace ($18,000–$35,000), or a concrete slab ($12,000–$25,000). Basements add the most living space and resale value; slabs are fastest and cheapest. The right choice depends on your lot's water table and bedrock, your budget, and whether extra space or single-level access matters more. Every home Modular Homes 400 sells today sits on a slab, pad or piers — General Coach homes don't go on a full basement.
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) 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.
Financing, mortgages & HST
Financing a Factory-Built Home in Ontario
Yes — you can finance a factory-built home in Ontario. A CSA A277 modular home on a permanent foundation on land you own is real property and finances like any other house. A CSA Z240 MH manufactured home is treated closer to personal property. The complication is timing: the factory needs payment while a construction mortgage releases funds in stages.
Can You Get a Mortgage on a Modular Home in Ontario?
Yes. A CSA A277 modular home on a permanent foundation on land you own is generally financed like any other house, with CMHC-insured mortgages available from 5% down. CSA Z240MH manufactured homes and homes in land-lease communities are where lenders differ — some say yes, many say no, and policies change. Of the major banks, RBC is the one with a program for homes on leased land; specialty lenders and credit unions cover much of the rest.
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's enhanced HST rebate is law: buyers of a new factory-built home — CSA A277 modular or CSA Z240MH manufactured — recover the full 13% HST, up to $130,000, on agreements of purchase and sale signed April 1, 2026 through March 31, 2027. On a modular home under $1M, effectively all the HST comes back; your lawyer handles the claim.
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 depends on your home's CSA standard. CSA A277 modular on owned land finances through standard residential, construction, or CMHC-insured mortgages (minimum 5% down). CSA Z240MH manufactured — including the Parkland Series — uses manufactured-housing mortgage programmes until deregistered to real property, when a standard residential refinance becomes available.
