Alternative Housing Options in Canada: Container Homes, Cohousing, Straw Bale and Earthships (2026)
Updated
High prices have pushed many buyers to look past the conventional single-family home. This guide covers the alternatives that don’t have their own guide on this site, shipping container homes, cohousing, and straw bale and earthship builds, with their costs, zoning and financing, and compares them with the factory-built, tiny and laneway options. It is part of our guide to property types in Canada.
Modular homes are built in sections in a factory, then assembled on a permanent foundation; one certified to CSA A277 is financed like a site-built house, often with a construction loan that pays the factory in stages. Which factory-built homes qualify for a mortgage is covered in mortgages for modular and manufactured homes.
Tiny homes, on wheels or on a foundation, have their own zoning, insurance and financing problems, covered in buying a tiny home. Laneway houses and garden suites are secondary homes on an existing lot, with size limits set city by city; the rules, costs, financing and rental income are in laneway houses and garden suites, and government programs for building a suite in secondary suite incentives.
Container homes
Shipping container homes use repurposed steel containers (20 ft or 40 ft) as structural elements. Single containers create compact studios; multiple containers can be combined into full-size homes.

Zoning and permits for container homes
Jurisdiction

Vancouver

Key rule: If the container home meets provincial building code, has engineering stamps, passes inspection, and is on a permanent foundation on owned land ; it will be treated as a house by both the municipality and the lender.
Cohousing
Cohousing communities feature privately owned units with shared common spaces (kitchen, garden, workshop, laundry). Residents participate in governance and shared maintenance. Community land trusts and co-living rentals, which share some of these ideas but not the ownership model, are covered in co-living and community land trusts.
