Smart Living Solutions

More Than Extra Space.
A Smart Investment.

An accessory dwelling unit is one of the highest-ROI improvements you can make to a residential property. Whether you're creating rental income, housing aging parents, providing a space for adult children, or building a dedicated home office, an ADU adds both function and significant property value.

Ontario's Bill 23 now requires municipalities to allow up to three residential units per lot. The Region of Waterloo has updated its bylaws accordingly. Caliber Contracting has deep expertise in navigating the specific zoning requirements for Kitchener, Waterloo, Cambridge, and surrounding municipalities — including setbacks, lot coverage, parking requirements, and fire code compliance.

We build detached garden suites, basement apartments, above-garage units, and attached secondary suites — each designed to feel like a complete, independent home, not an afterthought.
