ADU & GARAGE SUITE BUILDERS IN KITCHENER WATERLOO

An additional dwelling unit is one of the smartest ways to get more out of a property you already own — rental income, a home for aging parents, a space for an adult child, or room for family to visit — all without moving. The catch is that most homeowners don’t know where to start, and the zoning and permits feel like a wall. That’s the part we take off your plate. 

McFalls Construction designs and builds ADUs across the Waterloo Region — in Kitchener, Waterloo, Cambridge, New Hamburg, and the surrounding townships — and we handle the approvals from day one.

What an ADU Can Be

An ADU — also called an additional dwelling unit, secondary suite, or garden suite — is a self-contained home on the same lot as your main house, with its own kitchen, bathroom, sleeping area, and entrance. In our region that can take a few forms: a detached garden suite in the backyard, a converted garage, or a suite built into or added onto your existing home. We’ll help you figure out which one fits your property, your budget, and your goals. 

Why BUILD YOUR ADU McFalls

Permits and zoning, handled.
We start with a feasibility check on your specific lot, then manage the building permit and any approvals. 

Built for your goal.
Rental income, in-law suite, or space for family — we design around how you’ll actually use it. 

Quality that holds its value.
A unit built to last and built to feel like a real home, not a shed with a kitchen.

Honest communication.
Clear budgets and steady updates from first sketch to final inspection. 

Local and family-run.
We know the Waterloo Region’s municipalities and how their ADU rules differ. 

How the Process Works

Building ADUs across the Waterloo Region

Municipalities across the region now permit ADUs in most residential zones, but the details — lot coverage, setbacks, servicing, and access — vary by property and by city, and not every lot supports every type. Knowing those rules is half the job, and it’s a job we do all the time.
