Open building permit

An open building permit is a permit for construction work whose required inspections have not been completed, so it has not been closed. The City of Toronto says the property owner is responsible for outstanding permits, including where a previous homeowner did the work.

A buyer of a business that owns or leases premises meets this when renovations or additions were done before the sale. This entry covers Ontario and Toronto only; check the rules where the premises are. For the wider checks, see what environmental checks you need before buying a business.

How it works in Ontario

  • Ontario’s Building Code Act, 1992, s. 8(1), says no person shall construct or demolish a building, or cause that to be done, unless the chief building official has issued a permit.
  • The City of Toronto says a building permit remains open until all required inspections are completed and the permit is officially closed.
  • Toronto says open permits can create issues for property owners, including delays when selling a home, challenges obtaining new permits and potential enforcement actions.
  • Toronto says that if the work was done by a previous homeowner, the current owner is still responsible for closing the permit.

What to ask

Ask the seller for the permits issued on the premises and whether each is closed. A work order and outstanding permit search shows what the municipality has on file. Ask the municipality what is needed to close a permit and who must request the inspection.
