Garden Suite Rental Income
in Ontario — What the
Numbers Actually Look Like
A garden suite can generate meaningful rental income in Simcoe County — but the numbers depend heavily on your municipality, unit size, and quality. Here are the real 2025 market rates, an honest ROI breakdown, and what Ontario’s tenancy law means for you as a first-time landlord.
Ranges reflect well-built detached garden suites vs. standard apartment market. Garden suites command a premium for privacy and quality. Rents softened ~10% in Barrie during 2025. All figures are estimates based on available market data — confirm with local listings before finalising your financial model.
A well-built one-bedroom garden suite rents for roughly $1,400 to $2,100 a month across Simcoe County, with Barrie and Collingwood at the top of the range. Units first occupied after November 15, 2018 are exempt from Ontario’s rent increase guideline, but you still need the Ontario Standard Lease and 90 days’ written notice for any increase.
What Garden Suites Actually Rent For —
and What’s Happening to the Market
The Simcoe County rental market in 2025 is different from 2023 or 2024. Rents in Barrie softened noticeably — down roughly 10% year-over-year by late 2025 after a period of sharp increases. Understanding the current market, not peak market, is the honest way to model your project’s financial return.
Important market context for 2025: Barrie one-bedroom rents peaked around $1,963/month in early 2024, then declined to approximately $1,750/month by late 2025 — a meaningful correction driven by increased new rental supply and cooling demand. Models built on 2023 peak rents will overstate your actual returns. Use current market rates, not recent highs, when evaluating whether your project’s numbers work. That said, rents across Ontario have increased substantially from 2018–2022 levels and garden suites continue to command a meaningful premium over standard apartments due to their privacy, quality, and detached character.
| Municipality | 1-bed suite est. | 2-bed suite est. |
|---|---|---|
| Barrie | $1,700–$2,100 | $1,950–$2,400 |
| Collingwood | $1,800–$2,200 | $2,100–$2,600 |
| Wasaga Beach | $1,500–$1,900 | $1,800–$2,200 |
| Midland / Penetang | $1,400–$1,800 | $1,700–$2,100 |
| Tiny / Springwater (serviced) | $1,400–$1,750 | $1,650–$2,000 |
| Rural / Oro-Medonte | $1,300–$1,700 | $1,550–$1,950 |
Garden suite estimates are typically 10–20% above comparable apartment rents due to privacy, detached construction, and quality. These are 2025 estimates — always check current local listings on Zumper, Rentals.ca, and Kijiji before finalising your financial model. Smaller markets (Midland, Wasaga Beach) have fewer comparable listings and higher rent volatility.
Why Garden Suites Rent Above the Standard Apartment Market
A well-built detached garden suite rents for a meaningful premium over a comparable-size apartment in the same market — and for good reasons that tenants understand and value.
No shared walls. A detached garden suite offers genuine acoustic privacy that even high-quality apartment buildings cannot match. For tenants who work from home, have children, or simply value quiet, this is worth a real rent premium.
Private outdoor space. Access to a defined outdoor area — even a small patio or garden — is a significant differentiator in markets where most rental stock is apartment-only. Tenants with pets, active outdoor lifestyles, or young children value this highly.
Newer construction quality. The majority of Simcoe County’s rental stock consists of older apartment buildings and converted houses. A new garden suite built to the 2024 OBC — with modern insulation, HRV ventilation, energy-efficient windows, and a well-designed kitchen — is genuinely superior to most available stock. Tenants notice and pay accordingly.
Direct landlord relationship. Tenants in garden suites typically have a more direct relationship with the property owner, faster maintenance response, and a quieter, more residential setting than a multi-unit building. For many tenant profiles, this is a strong preference.
Setting your rent appropriately requires understanding current local comparables — not just the general market averages above. Check active listings in your specific neighbourhood on Rentals.ca, Kijiji, and Zumper before setting your asking rent.
Garden Suite ROI — Realistic
Simcoe County Numbers
These are worked examples using representative 2025 Simcoe County figures. Your numbers will differ based on your total build cost, your municipality, your financing structure, and the rent you achieve. Use these as a framework, not a guarantee.
Example A — Barrie 1-Bedroom Garden Suite, Cash Purchase
Urban serviced lot · Mid-range finish · No mortgage on the garden suite · $280,000 all-in build cost
Assumptions
Returns
Example B — Barrie 1-Bedroom Garden Suite, HELOC-Financed
Same project · $100,000 from savings, $180,000 via HELOC at 5.5% (prime+0.5%) · Rent partially offsets interest cost
Assumptions
Returns on Cash Invested
The key insight from both examples: At current Simcoe County build costs and rental rates, a garden suite generates a meaningful yield — but it is not a get-rich-quick investment. The financial case is strongest when you consider three streams together: ongoing rental income, property value appreciation, and in some cases the personal value of housing a family member. Each stream is real; none should be ignored in isolation. Use our interactive cost and ROI calculator to model your specific project with your own numbers. Here is how reporting rental income works.
What Drives Garden Suite Rent in
Simcoe County
Two garden suites built in the same municipality on the same street can command rents that differ by $300–$500 per month. Here are the factors that explain that difference — and that you can influence through design and build decisions.
1. Location and Transit Access
In Barrie, proximity to the South Barrie GO station or major employment nodes commands a premium. In Collingwood, walkable distance to downtown or the Georgian Trail matters. In Wasaga Beach, proximity to the beach and services. In more rural areas, the premium for location is less pronounced — but ease of access to services and highways still matters to tenants. A 10-minute walk to amenities vs. a 20-minute drive is a meaningful rent differential.
2. Unit Size and Layout Efficiency
A well-laid-out 550 sq ft one-bedroom garden suite with proper light, storage, and an efficient kitchen will rent for more than a 650 sq ft poorly planned unit. Size matters — but so does how usable the space is. In a smaller unit, every square foot must work. Open-plan kitchen-living, good natural light, and in-unit laundry are the three features that most consistently move tenants to pay a premium in the Simcoe County market.
3. In-Unit Laundry
Tenants in Simcoe County rate in-unit laundry as one of the most important amenity factors — particularly in smaller communities where laundromats are limited. A washer/dryer in the unit adds at minimum $100–$150 per month to achievable rent in most Simcoe County markets. It also reduces tenant turnover, which matters more than the monthly premium. Design laundry into the suite from the start — it is very difficult to add after the fact.
4. Construction Quality and Finish
Tenants can feel the difference between a well-insulated, draft-free, properly ventilated suite and one built to minimum code. Cold floors, drafty windows, poor soundproofing, and noisy heating systems are tenant complaints — and they affect both rent and tenant retention. A garden suite built with ICF walls, quality windows, and an HRV system will command a sustained rent premium over its full rental life compared to a minimum-standard build. ICF guide →
5. Parking and Outdoor Space
One dedicated parking space is the practical standard for Simcoe County garden suite tenants — most of whom own a vehicle. No parking means a significantly reduced tenant pool and lower achievable rent. A small private patio or garden area, even 50–100 sq ft, meaningfully increases the unit’s appeal. These are design decisions made early — parking can be engineered into the site plan from the start, or impossible to add afterward.
6. All-Inclusive vs. Utilities Separate
In Simcoe County’s smaller markets, many tenants expect utilities to be included in rent. An all-inclusive rent of $1,950/month may actually net you less than a utilities-separate lease at $1,750/month — depending on the suite’s actual heating cost. For a well-insulated garden suite, separating utilities typically favours the landlord financially. For an older-code or less energy-efficient suite, inclusion protects you from liability if bills are high. Be explicit about the arrangement in the lease.
New Garden Suites and
Ontario’s Rent Control Rules
Ontario’s rent increase guideline does not apply to all rental units. New garden suites built today enjoy a meaningful exemption — and understanding it is important to modelling your long-term returns accurately.
The Rent Control Exemption — Key Facts
What This Means Practically
Every garden suite built and first occupied today is exempt from the annual rent increase guideline. This means that when your tenancy renews, you can negotiate any rent increase — you are not capped at 2.5% or 2.1%. This does not mean you should maximise rent increases arbitrarily — tenant retention is more valuable than wringing out every extra dollar — but it does mean your rent can keep pace with the market over time.
You can only raise rent once every 12 months regardless of the exemption. And you must provide the tenant with 90 days’ written notice of any rent increase — using the official N1 form from the Landlord and Tenant Board.
The exemption applies to the unit, not the tenancy. If a new tenant moves in, you can set the rent at whatever market rate is appropriate at that time — the previous rent is not binding on a new tenancy for a unit first occupied after November 15, 2018.
Important: If you are using the Simcoe County Secondary Suites forgivable loan, your rent must remain at or below the County’s approved alternate average market rent for the term of the agreement. The exemption still applies — but you have agreed contractually to a rent ceiling as a condition of the funding.
Ontario’s Residential Tenancies Act —
What You Need to Know Before You Rent
The Residential Tenancies Act (RTA) governs every rental relationship in Ontario. Understanding the key obligations before you accept your first tenant avoids the expensive surprises that catch many first-time landlords unprepared. This is not legal advice — speak with a paralegal or lawyer familiar with tenancy law for guidance on your specific situation.
Landlord Responsibilities
Use the Ontario Standard Lease
Mandatory for all residential tenancies in Ontario since April 30, 2018. Must be provided to the tenant within 21 days of signing. Available from the Ontario government website. Do not use a custom lease or one from another province.
Provide and Maintain Essential Services
You must ensure the unit has functioning heat, water, electricity, and is safe and well-maintained at all times. You cannot cut off essential services even if rent is unpaid. Maintenance requests must be responded to promptly.
24-Hour Written Entry Notice
You must provide at least 24 hours’ written notice before entering the rental unit — for inspections, repairs, or showing the unit to prospective tenants. Entry must be between 8am and 8pm. The only exceptions are emergencies or if the tenant agrees to an earlier entry.
Deposit Rules — First and Last Only
You can collect a deposit of first and last month’s rent only. No security deposit, damage deposit, key deposit (beyond a refundable key cost), or pet deposit is permitted under the RTA. Last month’s rent deposit must be applied to the last month when the tenancy ends.
Rent Receipts
If a tenant requests a receipt for rent paid, you must provide one. Keep records of all rent payments. Most landlord-tenant disputes benefit from clear payment records on both sides.
Report Rental Income
Rental income from your garden suite must be reported on your annual T1 income tax return. You can deduct eligible expenses (mortgage interest if applicable, property tax proportion, insurance, maintenance, depreciation). Speak with an accountant familiar with rental property tax.
Things First-Time Landlords Get Wrong
Trying to End a Tenancy Without Proper Process
Once a tenancy is established under the RTA, you cannot simply ask a tenant to leave. Eviction must follow specific processes through the Landlord and Tenant Board. Valid grounds include non-payment of rent, substantial interference, illegal activity, or personal use (owner moving in with strict conditions). The process has specific notice periods and forms. Self-help evictions — changing locks, removing belongings, shutting off utilities — are illegal and can result in significant penalties.
Not Understanding Rent Increase Notice Requirements
Even for exempt units, you must use Form N1 and provide 90 days’ written notice before a rent increase takes effect. An increase given with less notice is not legally enforceable for the full notice period. Mark rent increase notice deadlines in your calendar.
Ignoring Maintenance Obligations
Landlords are legally required to maintain the unit in good repair, complying with health and safety standards. Ignoring maintenance requests not only creates legal exposure but damages the landlord-tenant relationship and incentivises tenants to withhold rent or seek rent abatements through the LTB.
Not Documenting the Unit Condition at Move-In
Complete a detailed condition inspection with the tenant at move-in, signed by both parties with photos. This is the only protection you have if there is a dispute about damage at move-out. The RTA does not allow a security deposit — so pre-existing damage documented at move-in is your evidence if the tenant causes damage beyond normal wear and tear.
Assuming STR Use Is Simple
Short-term rental through Airbnb or VRBO in a garden suite is subject to your municipality’s STR licensing bylaw (Barrie, Collingwood, Wasaga Beach, and others have active STR regulations). STR income is taxed differently and is not eligible for the Simcoe County forgivable loan. If STR is your intended model, confirm local licensing requirements before committing to that path.
Bill 60 update (November 2025): Ontario passed the Fighting Delays, Building Faster Act (Bill 60) on November 24, 2025, making significant amendments to the RTA including shortening the grace period for rent arrears from 14 to 7 days and changing fixed-term lease renewal rules. Confirm the current in-force status of these amendments before relying on them — stay informed via tribunalsontario.ca and consult a tenancy paralegal or lawyer for current guidance before relying on any specific RTA provision.
The Forgivable Loan Rent Requirement —
What It Means for Your Financial Model
The Simcoe County Secondary Suites forgivable loan requires you to rent at or below the County’s approved alternate average market rent for 15 years. This affects how you model your returns if you are using the program funding.
The Rent Ceiling Under the Program
In exchange for the forgivable loan — up to $50,000 as a 15-year forgivable loan in Simcoe County municipalities, with a Barrie municipal bonus that can lift the combined local funding to up to $65,000 — you commit to renting the unit at or below the County’s published alternate average market rent for a 15-year term. The County publishes updated maximum rents annually.
In practice, the County’s alternate average market rent for Simcoe County has typically been below the open market rate — but not drastically so. For a 2025–26 one-bedroom unit, the program rent ceiling is in the range of the lower end of the market rates shown in our table above. You are not renting at a nominal amount — you are renting at an affordable (but realistic) rate.
The financial trade-off: If you could charge $1,900/month at open market but the program caps you at $1,600/month, you are foregoing $300/month = $3,600/year in income. Over 15 years, that is $54,000 in foregone rent. The forgivable loan provides up to $50,000 (up to $65,000 with the Barrie municipal bonus). Whether the trade-off works for you depends on your specific market, the gap between market and program rents, and whether you have other financing strategies available.
Some homeowners use the forgivable loan specifically to reduce the amount they need to borrow — lowering their financing cost more than offsetting the foregone rent. Others prefer full market rent and use alternative financing. There is no universally right answer — it depends on your numbers. Full financing guide →
Modelling Both Scenarios Before You Apply
Before applying for the forgivable loan, model both scenarios explicitly:
Scenario A — Market rent, no loan: Total income at open market rate over 15 years, minus standard financing cost. What is your total net income and remaining mortgage/HELOC balance at year 15?
Scenario B — Program rent, forgivable loan: Total income at program rent ceiling over 15 years, plus the value of the forgivable loan (which reduces your financing need and therefore your interest cost). What is your total net income at year 15?
The comparison is rarely as simple as “I’m getting free money.” The forgivable loan comes with a 15-year commitment, a mortgage registered on title, and a requirement to maintain income-eligible tenants. If you sell before the term ends, the unforgiven balance becomes repayable. These are material constraints on what is nominally “free money.”
For many Simcoe County homeowners — particularly those in municipalities where the gap between market and program rent is small — the forgivable loan is an excellent program and the numbers work well. Do the comparison for your specific situation before deciding. We can walk through this with you →
