Complete Homeowner’s Guide to ADUs in Rural Ontario

Build Smart. Live Better. Create Space with Purpose.

What is an ADU (Accessory Dwelling Unit)?

An Accessory Dwelling Unit (ADU)—also known as a garden suite, in-law suite, secondary unit, or coach house—is a self-contained living space built on the same property as your main home. In rural Ontario communities like Brant, Haldimand, and Norfolk Counties, ADUs are becoming the ideal solution for:

Why Rural Ontario is the Perfect Place for ADUs

Unlike city lots, rural properties often offer:

  • More space and privacy
  • Simpler zoning pathways with fewer building constraints
  • A better return on investment due to lower land acquisition costs
  • Flexible use for home offices, rentals, or family accommodations

If you’re in Brant County, Brantford, Paris, Simcoe, Hamilton, Norfolk, or Haldimand, you may already be eligible to build an ADU—and not even know it.

Are You Allowed to Build an ADU in Your Area?

Yes—thanks to changes in Ontario’s Bill 23, many municipalities now allow homeowners to build a second unit on their property. Here’s what you need to know for Brant County and surrounding regions:

  • Most single-detached, semi-detached, and rowhouse properties qualify.
  • ADUs can be detached, above garages, or converted from existing structures.
  • You’ll still need to follow zoning bylaws, setback requirements, and building code standards—but that’s where we come in.

Book a free zoning assessment with Frontier Building Group to confirm if your property qualifies.

  • Above-garage apartments
  • Converted workshops or barns
  • Basement in-law suites with private entrances
