The Simcoe County Secondary Suite Grant Program

What the County is trying to do, and why you should care

The goal is simple: increase the supply of rental housing by helping homeowners create legal suites – units that meet the Ontario Building Code and local zoning, 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.

From a homeowner’s view this can be a genuine win-win: you add a legal unit and potential income, and your community gets more housing on already-serviced land. If you are building in a Simcoe County municipality – Barrie, Orillia, Innisfil, Collingwood, New Tecumseth, Bradford West Gwillimbury, Essa, Midland, Penetanguishene, and others – remember the municipal side (zoning plus permits) is still the gatekeeper. Ontario’s broader framework also supports up to three units per lot on many serviced residential lots under Bill 23, but your municipality applies the actual standards – see garden suites in Ontario.

Key details for 2025-2026

The County’s 2025-2026 fact sheet describes the program as a 15-year forgivable loan (currently up to $50,000) to create a secondary or garden suite, with limited funding and a note that advanced projects – ones actually ready to begin construction – can be prioritized. In plain homeowner language: if your paperwork is tight, your plans are realistic, and you can actually start, you are in a better spot than someone “thinking about it someday after hockey season.”

Eligible expenses (what tends to be covered)

Your actual eligible list is defined by the County’s current application package and approvals, but the typical categories are:

• Construction and renovation: framing, insulation, drywall, flooring, plumbing, electrical, and HVAC.
• Site servicing: water and 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.

The requirements that actually matter (and where people blow it)

1. Owner occupancy

Some requirements are tied to the funding stream. The 2025-2026 FAQ notes that certain funding – referencing the Ontario Priorities Housing Initiative – requires the applicant to be owner-occupied during the term. 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 are not optional

If you want funding for a legal unit, you need a legal unit – permits, inspections, and compliance with the Ontario Building Code and local bylaws. Start with your municipality’s building department and confirm what they want for drawings, fire separation, egress, smoke and CO alarms, and servicing. If you are unsure how permits work in Ontario, see how to obtain a building permit in Ontario and the official Ontario Building Code.

3. The “do not start early” rule

This is the big one. The County’s application materials and FAQ are very clear that work completed before final approval may not be eligible for coverage. In other words: apply first, get approval, then build. This is the rule that catches people “just doing a little demo to get ahead” – that little demo can become “expenses incurred prior to approval,” which is a painful sentence to read after the fact.

Step by step: how a clean application usually works

Septic note: if your project touches septic capacity (common on rural lots and some garden suites), learn the basics before you draw your first line – see garden suite septic requirements and septic and well checks.

Why the big push for garden suites?

The “why” is policy plus practicality. Ontario has been pushing municipalities to add housing in existing neighbourhoods, and up to three units per lot has become a recurring direction. Garden suites are efficient: they add a brand-new unit while leaving your main house mostly untouched, and they use existing serviced land – so the community adds housing without new roads, subdivisions, and watermains for every unit. From the County’s point of view a backyard unit is new housing stock; from yours, it is a way to house family, add long-term rental income, or create future flexibility for kids, parents, or downsizing.

Common mistakes to avoid

• Starting work before approval. The big one – apply and get approval first, or you risk your funding.
• Assuming an unfinished basement equals an 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.
• Comparing quotes without specs. “Legal suite” can mean very different build-ups and materials.
• Contract gaps. If you hire trades, protect yourself with clear scope, allowances, and change-order rules, and understand lien rights and holdbacks – see how to register a construction lien in Ontario.

Where to get the most current info (do this first)

Program details and funding caps can change, and intake can fill up. Your first stop should always be the County’s official page: Simcoe County – Affordable Housing Programs, and the Social Housing department can confirm the current maximum and availability. Your second stop is your local municipality’s ARU page or building department, because zoning and permit requirements are municipal.

Note: program terms, maximums, and eligibility can change and are administered by the County of Simcoe. Confirm current details with the County’s Affordable Housing Programs page and Social Housing department, and confirm zoning and permit requirements with your municipality, before relying on them.
