Grand River Modular

🚨 Big news for Ontario homeowners 🚨

The rules have moved in your favour. Many lots can now hold up to three homes, and one of those can sit behind the house, fully detached (an ADU). No rezoning needed.

Building costs keep going up. But the land out back? You already own it.

We're Grand River Modular, a licensed builder operating across Ontario. We build the whole home in our shop, then bring it to you.

Why people pick us:

* We handle the permits and paperwork
* No weather delays and no torn-up yard
* A building inspector signs off every stage
* Set on your foundation in days, not months

Need space for family? Want rent coming in? Want your place worth more?

Step one is free: find out what you're allowed to build.

400 square feet. At least six ways to use it.
Most backyard builds get locked into one purpose. A shed stays a shed. A garage stays a garage. Once it goes up, you are stuck with whatever it was meant to be on day one.
Our ADU builds are fully serviced, independent homes on the same footprint:

Rental income suite
Space for aging parents close by
Backyard home office or studio
First place for an adult kid
Guesthouse for visiting family
Future caregiver suite

You do not have to pick today. The use can shift through the years.
Permit timelines and municipal funding windows shift every year. Locking in a 2026 build start protects this season's pricing and approval pathway.
Free property assessments and facility tours available.
