Simcoe County Secondary Suite & Garden Suite Funding (2025–2026): A Homeowner’s Guide That Won’t Get You Denied
Simcoe County has been actively promoting Additional Residential Units (ARUs)—things like basement apartments, attic suites, and detached garden suites—as a practical way to add housing without paving over more farmland. If you’ve ever looked at your basement or backyard and thought, “This could be a legal rental unit,” there’s a County program designed to help offset some of the cost—if you follow the rules.
Let’s start with the big picture: Simcoe County’s program exists because Ontario needs more rental units, and building a legal suite is one of the fastest ways to add them. The County delivers a Secondary Suites Program and publishes current program details through its housing pages and program materials. :contentReference[oaicite:0]{index=0}
What Counts as an ARU?
- Secondary suite: usually in the basement, main floor, or attic.
- Garden suite: a detached unit in the backyard (coach house / garden apartment).
- Same lot, more housing: new unit without buying new land.

Quick correction that matters: homeowners often call this a “grant,” but Simcoe’s 2025–2026 materials describe financial assistance as a 15-year forgivable loan (up to a stated maximum) for creating a secondary or garden suite, with limited funding and a first-come-first-served approach. :contentReference[oaicite:1]{index=1}
Overview: What Simcoe County Is Trying to Do (and Why You Should Care)
Simcoe County’s goal is simple: increase the supply of rental housing by helping homeowners create legal suites. That means units that meet Ontario Building Code requirements and local zoning standards, not “my cousin framed it and we called it a day.”
The County describes the Secondary Suites Program as funding to help create a secondary or garden suite, with intake available year-round (subject to limited funding). :contentReference[oaicite:2]{index=2}
From a homeowner perspective, this can be a win-win: you add a legal unit (and potential rental income), and the community gets more housing without requiring new subdivisions or major infrastructure expansions.
If you’re doing this in Simcoe County municipalities—Barrie, Orillia, Innisfil, Collingwood, New Tecumseth, Bradford West Gwillimbury, Essa, Midland, Penetanguishene, and others—the municipal side (zoning + permits) is still the gatekeeper. The County program does not override your town’s rules. :contentReference[oaicite:3]{index=3}
Key Details for 2025–2026 (What the County Says)
The County’s published 2025–2026 fact sheet describes the program as a 15-year forgivable loan to create a secondary or garden suite, with a maximum amount stated in the program materials. It also notes that funding is limited and advanced projects (ready to begin construction) can be prioritized. :contentReference[oaicite:4]{index=4}
Translation into normal homeowner language: if your paperwork is tight, your plans are realistic, and you can actually start the project, you’re in a better position than someone who’s “thinking about it someday after hockey season.”
Eligible expenses (what tends to be covered)
Program materials and municipal guidance commonly reference a wide range of costs that can apply to bringing a unit into compliance—construction and renovation items, servicing upgrades, and certain professional fees. Barrie’s ARU page, for example, explicitly reminds homeowners to budget for design, permits, materials, construction, and servicing upgrades. :contentReference[oaicite:5]{index=5}
Your actual eligible list will be defined by the County’s current application package and approvals, but the typical categories look like this:
- Construction & renovation: framing, insulation, drywall, flooring, plumbing, electrical, HVAC.
- Site servicing: water/sewer upgrades or septic-related work (where applicable).
- Professional fees: drawings, engineering, permits, and planning-related costs (where required).
- Accessibility modifications: certain program materials also reference accessibility-related support. :contentReference[oaicite:6]{index=6}
Builder tip: “Eligible” doesn’t always mean “automatic.” Keep every receipt, keep your approvals organized, and don’t assume that a cost is covered unless it’s in writing in your agreement/package.
The Requirements That Actually Matter (and Where People Blow It)
1) Owner occupancy and program rules
Some program requirements are tied to the funding stream. A 2025–2026 FAQ document notes that certain funding (referencing the Ontario Priorities Housing Initiative) requires the applicant to be owner-occupied during the term. :contentReference[oaicite:7]{index=7}
In plain terms: this program is aimed at adding stable, long-term rental housing—not flipping properties or running short-term rentals.
2) Permits and inspections aren’t optional
If you want funding for a legal unit, you need a legal unit. That means permits, inspections, and compliance with Ontario Building Code and local bylaws. Start with your municipality’s building department and confirm what they want for drawings, fire separation, egress, smoke/CO alarms, and servicing. You can also read Ontario’s official Building Code resources here: Ontario Building Code (official).
If you’re unsure how permits work in Ontario (especially timelines and “what triggers a permit”), this walkthrough helps: How to obtain a building permit in Ontario.
Reality check: the cheapest way to do a suite is usually the most expensive way—because failing an inspection (or discovering you can’t legalize what you built) is where budgets go to die.
3) The “don’t start early” rule
The County’s application materials and FAQs are very clear that work completed before final approval may not be eligible for reimbursement/coverage. In other words: apply first, get approval, then build. :contentReference[oaicite:8]{index=8}
This is the rule that catches people who are “just doing a little demo to get ahead.” That “little demo” can become “expenses incurred prior to approval,” and that’s a painful sentence.
Step-by-Step: How a Clean Application Usually Works
Here’s the process I recommend to homeowners so you don’t waste time (or money) bouncing between departments:
- Step 1 — Confirm zoning and feasibility: call your town/city planning department. Ask if a secondary suite or garden suite is permitted and what constraints apply (lot coverage, setbacks, parking, servicing, heritage, etc.).
- Step 2 — Pre-consult with building: building staff will tell you what they expect for drawings and code items (egress, fire separation, alarms, ceiling heights).
- Step 3 — Get preliminary plans + budget: even a “rough” plan should show layout, exits, windows/egress, and mechanical room strategy.
- Step 4 — Apply to the County first: the County program has limited funding and year-round intake; don’t assume money will be there later. :contentReference[oaicite:9]{index=9}
- Step 5 — Receive approval/conditions: if you’re approved, you’ll get conditions and documentation requirements.
- Step 6 — Submit for permits: now you finalize drawings and go through municipal permits and inspections.
- Step 7 — Build + pass inspections: keep inspection reports and paperwork organized.
- Step 8 — Provide documentation: receipts, approvals, and whatever the program requires to finalize funding.
Septic note: if your project involves septic capacity or changes (common with rural properties and some garden suites), learn the basics before you draw your first line: Septic Systems Ontario.
Why the Big Push for Garden Suites?
The “why” is policy + practicality. Ontario has been pushing municipalities to add housing in existing neighborhoods, and “up to three units per lot” has been a recurring recommendation and direction in provincial housing discussions. :contentReference[oaicite:10]{index=10}
Garden suites are efficient: they add a brand-new unit while leaving your main house mostly untouched. They also use existing serviced land—meaning the community can add housing without building new roads, new subdivisions, and new watermains for every unit.
From the County’s point of view, a backyard unit is “new housing stock.” From your point of view, it’s also a way to house family, add long-term rental income, or create future flexibility (kids, parents, downsize plans).
Practical builder advice: if a detached garden suite is your plan, start with setbacks, servicing, and access for construction (crane/truck path, excavation route, where spoil goes). If those don’t work, the prettiest plan in the world still won’t get built.
Common Mistakes (That I’d Love You to Avoid)
- Starting work before approval: this is the big one. Apply and get approval first. :contentReference[oaicite:11]{index=11}
- Assuming “unfinished basement” = easy suite: egress, fire separation, ducting, and ceiling height can change the scope fast.
- Underestimating servicing upgrades: water, sewer, electrical capacity, and septic can be real costs. :contentReference[oaicite:12]{index=12}
- Comparing quotes without specs: “legal suite” can mean very different build-ups and materials.
- Contract gaps: if you’re hiring trades, protect yourself with clear scope, allowances, and change order rules (and understand lien rights/holdbacks). Here’s a plain-English guide: How to Register a Construction Lien in Ontario.
Where to Get the Most Current Info (Do This First)
Programs and funding caps can change, and intake can fill up. Your first stop should always be the County’s official housing program page: Simcoe County – Affordable Housing Programs. :contentReference[oaicite:13]{index=13}
Your second stop is your local municipality’s ARU page or building department, because zoning and permit requirements are municipal. For example, municipal pages like Barrie’s outline local guidance and reference the County funding program (including notes about servicing upgrades and budgeting). :contentReference[oaicite:14]{index=14}
One more useful read: If your plan is to build a high-performance addition or garden suite and you want long-term comfort (not just “meets minimum code”), you’ll likely care about insulation, air sealing, and durability. Here’s a homeowner-friendly overview: Benefits of ICF Over Traditional Homes.
Bottom Line
Simcoe County is actively encouraging legal secondary suites and garden suites because they create real housing fast. The County’s current program materials for 2025–2026 describe limited funding, year-round intake, and financial assistance structured as a forgivable loan (with the maximum amount stated in program documents). :contentReference[oaicite:15]{index=15}
If you want the best chance of success: confirm zoning, talk to building early, apply before you start work, keep documentation clean, and build it to pass inspections the first time. That’s the boring path—and it’s also the cheapest path.
