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.

Exploring ADU options? Start out with the right information.

Grand River Modular offers free Build-Ready Checks, facility tours and full project price estimates.

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.

What a backyard home really does to your property taxes, in plain English.

Avoid the confusion. Start with three facts.

1. The home stays on the same property, but the assessment changes.

For the 2026 tax year, MPAC values the updated property as if the backyard home existed on January 1, 2016, not at today’s build price. Your municipality may then send a supplementary tax bill, sometimes after the home is complete.

2. Get the full property picture before you pay for plans.

Our free Build-Ready Check looks at the zoning, lot fit, servicing and honest cost picture. It shows you what your property can support and where the real cost variables sit. Full property checks like this typically run $3,500 or more. Ours is free.

3. Look at the whole trade-off.

What it adds - what it costs = whether it makes sense. Space, possible rent and potential property value go on one side. The build, property tax and upkeep go on the other.

At GRM, we’re local and family-owned. We believe in information, not a sales pitch.

How a backyard home moves from an idea to move-in day in Ontario.

1. The free Build-Ready Check. We check the zoning, lot fit and servicing before you spend money on plans.
2. The free facility tour. Walk through a home in progress, see how it is built and inspected, and talk through the layout that fits your property.
3. Design and permits. Survey, drawings, engineering and the permit submission to your municipality.
4. Foundation and services. The right foundation for the property goes in, followed by water, hydro, and sewer or septic work.
5. The build. Pre-designed homes are built in our facility while the site work moves ahead. Custom homes may use a mix of offsite and on-site work.
6. Delivery and set. The home arrives and is craned onto the foundation.
7. Connections, inspections and occupancy. The municipality signs off the completed work and the home is cleared for move-in.

The parts we control, we commit to. The parts we don't, we explain early. That's what we mean by measuring twice before you spend once.

The first two steps are free. Message us here or email [email protected] to book your Build-Ready Check, your facility tour, or both.

What does a backyard home actually cost in Ontario?

Ours start in the low $100,000s plus HST.

The difference is what's in that number. When we quote your project, we include the four things a lot of builders quietly leave out:

The foundation
Septic or sewer hookup
Running water and hydro to the new home
Survey, drawings, and engineering

On some lots, that's where most of the money actually goes. So if someone hands you a lower price without them, it's not really the price, and you'll feel the difference later when those costs land in your lap.

We'd rather you see the whole thing now.

What you're paying for is a finished home, checked by a municipal building inspector at every stage, both in our shop and once it's on your lot. And we work all of it out for your specific property before you've spent a dollar.

Your home has looked after your family for years.
What if it could do even more?

Families across Ontario are adding backyard homes (ADUs) to give aging parents their own place close by, help adult kids get a real start, or bring in rental income for retirement.

These are permanent, code-compliant homes built to last, not park models.
Wondering if your property could hold one? That's easy to find out, at no cost.

We check what your lot allows with a Build-Ready Check, then take care of the permitting, pre-construction, and the build from start to finish.
Permits and construction take months, so families hoping to have a home ready next year are starting the conversation now.

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.

"We love the idea of an ADU, but dealing with the city sounds like a nightmare."

If you have thought this, you are not alone. Confusing local rules and permit delays make it hard to know what you can actually build on your lot.

That part is our job. Many Ontario lots now allow a backyard home as of right, which means no rezoning and no fighting city hall to add one. Grand River Modular handles the zoning approvals, the engineering, and the permitting up front, so the city process is off your plate before we build your backyard home offsite.

Most homeowners have no idea their lot already qualifies. Want to know what yours allows?

"We've been talking about building an ADU... maybe next year."
If that sounds familiar, you're not alone.
Many homeowners put off building an ADU because they think the process will be overwhelming.
"Where do I begin?"
"How long will it take?"
"Is now the right time?"
At Grand River Modular, we're here to answer your questions and help you understand what's possible for your property.

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

Give your adult children the independence they need close to home. Saving for a first home is not easy.

An Additional Dwelling Unit (ADU) gives your adult children a place of their own while keeping them close to family.

They get their own kitchen, living area, bedroom, and bathroom, with the privacy of a real home and the comfort of having their family steps away.

The best part? When life changes, your ADU can be used for rental income, aging parents, or visiting family.
