What are the Proposed Amendments to the Ontario Building Code?

There are three amendments proposed to the Ontario building code. The first amendment is the inclusion of the term “Tiny Home” in the Ontario building code with the definition stated above.

The second amendment focuses on Off-site inspections. These inspections take place when a tiny home is built in a different place, not the final building location. It refers to factory-built tiny houses that are transported to the site after construction. The amendment would allow for a building permit and inspection from the officials where the tiny home is being constructed. It allows tiny homes to be built off the site in a non-factory environment.

Another part of this amendment is the need for a second building permit from the building officials where the tiny home is located. This is to ensure public safety and the two permits cover both the installation on the site and the safety of the building.

1 thought on “Ontario Tiny House Laws You Must Read Or Else…”

  1. Is it true that lofts in tiny homes will be illegal soon (or are already illegal?) So all of our living and sleeping space will have to be on one level? Does this apply to all tiny homes? Tiny homes on wheels? Tiny homes in communities? Tiny homes on private land? Or just to rentals and campgrounds? I mean, if I want to buy a piece of land, but I’m not too fussed about staying there permanently and might want to sell it later and take my house with me when I leave the land, will I be stuck with a crappy little Murphy bed instead of a nice cozy loft to sleep in?
