Quick Answer
Several Ontario municipalities offer grants of $35,000–$95,000 for Additional Residential Units (ARUs) rented at affordable rates. Barrie offers $35,000. Burlington offered $95,000 (ended October 2025). Simcoe County offers up to $50,000 at rents of $1,426/month including utilities for 15 years.
Why Municipalities Pay You to Build an ARU
Ontario municipalities face housing targets set by the province under the More Homes Built Faster Act. Many are offering direct grants to homeowners who add rental units — because it is far cheaper for a municipality to subsidize a private homeowner's construction than to fund social housing directly.
The math: a municipality pays you $35,000–$95,000 once. In return, you provide an affordable rental unit for 15+ years that the municipality doesn't have to build, own, or manage.
For you as the property owner, the grant can eliminate or dramatically reduce your cash investment — in some cases making the ARU essentially cost-free upfront.

How the Grant Changes Your ROI
Using the standard modular ARU model ($195,000 total project, $19,500 down payment):
| Scenario | Your Cash Investment | 5-Year Return | Annualized ROI |
|---|---|---|---|
| No grant | $19,500 | $56,043 | 31.1% |
| Barrie $35,000 grant | Down payment fully covered | Even higher | Exceptional |
| $50,000 grant | Down payment + surplus | Highest | Outstanding |
When a grant exceeds your down payment, your effective cash investment approaches zero — and your ROI becomes theoretically infinite on a cash basis.
The Simcoe County Model — Collingwood Example
Simcoe County's program has specific parameters worth understanding for the Collingwood/Barrie area market:
- Affordable rent ceiling (1-bed, includes utilities): $1,426/month
- Grant available: up to $50,000
- Commitment period: 15 years at CMHC-compliant rents
- Market comparison: 1-bedroom market rents in Collingwood are currently over $2,000/month
The trade-off: you accept $574/month less than market rent in exchange for a $50,000 upfront grant. Over 15 years, that foregone rent totals approximately $103,320. The $50,000 grant only partially offsets this — so the financial case depends heavily on how long you plan to hold the property and how strongly you value the grant-funded equity acceleration in the early years.
For garden suites specifically: Garden suites are currently exempt from rent control in Ontario, meaning you can increase rent between tenants. The 15-year grant condition only applies during a tenancy — on vacancy, you may re-set rent.
What to Confirm Before Applying
Every municipal program has different requirements. Before applying, confirm:
- Is the program currently active and funded?
- What is the approved unit size and type (garden suite, basement, laneway)?
- What is the exact affordable rent ceiling (and does it include utilities)?
- What is the commitment period?
- Does the grant require the homeowner to be owner-occupied on the main property?
- Are modular / factory-built units specifically approved? (Habitat28 has Burlington approval, for example)
- What documentation is required?

Frequently Asked Questions
Are modular homes approved for Ontario ARU grant programs?
Yes — CSA A277-certified modular homes are treated identically to site-built construction by Ontario municipalities. Habitat28 modular units have been specifically approved for Burlington ARU grant program.
Do I have to live on the property to get an ARU grant?
Most Ontario municipal ARU grant programs require owner occupancy of the main dwelling. You cannot collect a grant on an investment property where you do not live. Always confirm this condition with the specific municipality.
What happens if I stop renting at affordable rates during the grant commitment period?
Grant agreements typically include clawback provisions — if you violate the rent conditions within the commitment period (usually 15 years), you may be required to repay part or all of the grant. Review the grant agreement carefully before signing.
Is the Barrie ARU grant still available in 2026?
Grant programs change frequently based on municipal budgets and housing targets. Always confirm directly with the City of Barrie housing or planning department before making investment decisions. ModularHomes400.com can provide current referrals.
