Want your family closer, but need a little more space?

Having aging parents or adult children nearby can mean a lot. But sharing one house doesn’t always work for everyone.

A detached backyard home gives them their own kitchen, bathroom and living space, with you just a short walk away.

1. Fully self-contained
2. Built for year-round living
3. Customizable to suit your family’s needs

If this is something your family is considering, it’s worth checking what your property can accommodate before you start making plans.

A home for someone you love, just a few steps across the yard.

Maybe that's mom or dad keeping their own space and their own routine, close enough that visiting doesn't take planning. Or it's your adult kid wanting a place of their own while still being nearby.

Either way, everyone keeps their independence. Dinner together is just a walk across the yard, and when it's done, everyone's got their own front door to go home to.

We build permanent backyard homes at our facility in Brantford. If this is something you're weighing for your family, come walk through a current build with us, see the space, ask us whatever's on your mind.

If it looks like a fit, next step is a Build-Ready Check on your property. No cost, no pressure, just a clear read on what it can support.

As life changes, your home can change with you.

A backyard home (an ADU) can keep family close, bring in rental income, or add flexibility for whatever comes next, all without leaving the neighbourhood you love.

For most homeowners the sticking point is simple: not knowing what their lot allows or where to begin. Our free property assessment answers that first, so you know exactly what is permitted before you spend a dollar. From there we handle the permitting, pre-construction, and the build, and a municipal building inspector signs off every stage, in our shop and on your lot.

It costs nothing, and it's the step that makes every decision after it easier.

Grand River Modular

"We've been talking about building an ADU… maybe next year."

Sound familiar? You're not alone.

Most homeowners put off their ADU because the process feels overwhelming. Where do you even start? How long does it take? Is now the right time?

At Grand River Modular, we answer those questions and show you exactly what's possible on your property. Every home we build is inspected and signed off at each stage, in our shop and on your lot.

The best time to start your ADU was last year. The next best time is now.

Ready to see it for yourself? Book a free tour of our Brantford facility, current builds included. DM us, call (548) 900-9525, or email [email protected] to get on the schedule.

What is your backyard doing for you right now?

A backyard home (an ADU) can create rental income on land your family already owns. For many households that income goes toward the mortgage, while the home itself adds to what the property can do over time, whether that means a tenant now, a parent or adult child later, or a future sale.

The first step with Grand River Modular is a facility tour.

You can walk through our current builds in Brantford, see how the homes are built and inspected, meet with us in person and ask your questions. You get to decide whether we're the right builder for you, while we learn enough about your plans to determine whether the project is a good fit for the way we work.

If it is, we'll complete your Build-Ready Check at no cost. The check looks at what the property permits, where a home could fit, how it can be serviced and which site-work factors will shape the real cost.

If the project moves ahead, we manage the permitting, pre-construction and site work. Pre-designed homes are built in our facility once permits are in place, while site work moves ahead. A municipal building inspector signs off at each required stage, in our facility and on your lot.

We're a local, family-owned builder, and we believe the best place to start is by seeing the work and meeting the people who will be responsible for it.

A backyard home is not a renovation.

When you hire someone to build a detached one in Ontario, you are hiring them to build a new home. Licensed builder, building permit, Ontario Building Code compliance, new home warranty protection.

Hire someone who treats it like a renovation and the warranty you assumed you had may not exist.

Before you sign anything, ask two questions.

What is your HCRA licence number, and how will my home be enrolled with Tarion?

Will municipal building inspectors inspect the home at each required stage, including while it is being built offsite?

The answers should be clear before you sign.

Send us your address for a free Build-Ready Check and we will tell you what your own lot allows.

How do water, sewer and hydro get to a backyard home?

Water, sewer and hydro typically run underground to the backyard home, either from the house or the street, depending on the property and municipal requirements.

Servicing is also a big factor in what a project costs, which is why we look at it early rather than after the design is settled.

Before the drywall goes up, you can see how a home is really built.

The framing, wiring, plumbing and insulation are still open. That is when the work can be checked properly.

Every GRM home is inspected like a site-built home. A municipal building inspector signs off at each stage, in our shop and on your lot.

Book a free facility tour and walk through one of our current builds. See the work up close, ask questions and judge the build quality for yourself.
