June 27, 2025


What is Unpermitted Work?

Unpermitted work refers to construction or renovations done without obtaining the necessary approvals or permits from the local municipality.

Why Unpermitted Work Matters in Real Estate

In Canadian real estate, unpermitted work can create legal, safety, and financial risks for both buyers and sellers.



Examples include:
  • Basement finishing without permits
  • Structural changes without approval
  • Unauthorized decks or additions



Consequences may include fines, mandatory removal, or difficulty obtaining insurance and financing.



Understanding unpermitted work helps buyers conduct due diligence and negotiate remedies, and helps sellers address potential liabilities.

Example of Unpermitted Work in Action

The buyer discovered unpermitted work in the attic renovation, leading to a reduced offer to cover permitting and compliance costs.

Key Takeaways

  • Work done without required municipal permits
  • Poses legal and safety risks
  • Can delay or complicate sales
  • May result in fines or removal orders
  • Should be disclosed in property transactions

In 2021, Michael Piper was confronted with the reality that he wasn’t going to be able to afford a home in Toronto. He describes his family as “solid middle class,” but even with two incomes, they weren’t a match for the housing market.

So they got inventive. With help from Piper’s in-laws, they purchased an east-end townhome and converted into a duplex. When his in-laws moved out, the unit became a rental. Today, they’re at the tail-end of a triplex conversion that will allow their university-aged daughter to have her own space in the home.
