Key takeaways
  • Alberta's disclosure focus is the material latent defect, meaning a defect a reasonable inspection would not find, or one that makes the property dangerous or unfit for habitation.
  • A seller's licensee acting as sole agent must disclose to all buyers the material latent defects they know of, so a known defect you tell your realtor about is one they must disclose.
  • Disclosure duties attach to material latent defects and similar facts, not every fact you know, and a seller has no obligation to tell potential buyers the home is conditionally sold when accepting offers.

You are getting ready to list your home and you are wondering what you have to tell buyers. Maybe there was a basement leak years ago, an unpermitted renovation, or something in the home's history that you would rather not raise. It is a fair worry, and the answer depends on what kind of fact is involved.

This article explains the main idea Alberta uses, the material latent defect, who carries the duty to disclose it, and which facts do not have to be volunteered. It is general information, not advice on your own house.

This article covers the law of Alberta.

The key idea: the material latent defect

Alberta's real estate rules use the term material latent defect. It is a defect that cannot be discerned through a reasonable inspection of the property. It also covers a defect that makes the property dangerous or potentially dangerous to occupants, or unfit for habitation.

In plain words, latent means hidden. A cracked window a buyer can see at a showing is not hidden. A problem behind a finished wall that you know about, and that a home inspector would not reasonably find, is the kind of thing this term is aimed at.

RECA, the Real Estate Council of Alberta, has said that sellers cannot hide defects or mislead buyers about the condition of the property, and that sellers must disclose the material latent defects they know about.

Who has to disclose: you and your realtor

The rules put a direct duty on licensees. A seller's licensee acting as sole agent must disclose to all buyers the material latent defects affecting the property that the licensee knows of. If a seller tells their realtor about a known defect, the realtor must then disclose it.

That means you cannot treat a conversation with your realtor as private on this point. Your realtor is also required to disclose to you, in a timely manner, the relevant facts affecting the transaction that the realtor knows of.

Defects that are not physical

A defect is not always a crack or a stain. RECA's information bulletin gives an example of a non-physical defect: the seller lacks the appropriate building or other permits for the property. If you finished a basement or built a deck without permits, that is worth raising with your realtor and lawyer before you list.

What about past water damage, a former grow operation, or a death in the home? The rules in front of us define the duty by reference to material latent defects, meaning defects that are not discoverable on a reasonable inspection or that make the property dangerous or unfit for habitation. Whether a particular past event meets that test depends on the facts, including whether it left a lasting problem. Do not guess. Ask your realtor and a lawyer to look at your specific situation.

What can stay unmentioned

Disclosure duties attach to material latent defects and similar facts, not to every fact a seller knows. A clear example from RECA is that a seller has no obligation to tell potential buyers that the home is conditionally sold when accepting offers.

That is a narrow point, so do not stretch it. It does not mean you can stay quiet about a known defect. It also does not stop a buyer from asking you direct questions, and anything you say in answer should be true. Hiding a defect or misleading a buyer about the condition of the property is exactly what the RECA bulletin warns against.

Type of factGeneral position
Known material latent defectMust be disclosed by your licensee
Missing building or other permitsCan be a defect that must be disclosed
That the home is conditionally soldNo obligation to tell other potential buyers when accepting offers
Other history or eventsDepends on the facts; confirm with a lawyer

What to do before you list

If you are unsure whether something is a material latent defect, that uncertainty is itself a reason to get legal advice before listing, not after a buyer raises it.

Frequently asked questions

Do I have to disclose a defect a buyer could see for themselves?

The disclosure duty is built around defects that cannot be discerned through a reasonable inspection, or that make the property dangerous or unfit for habitation. An obvious, visible issue is less likely to fit that description, but you should still not mislead anyone about it.

If I tell my realtor about a problem, can I ask them to keep it quiet?

No, not for a material latent defect. A seller's licensee acting as sole agent must disclose to all buyers the material latent defects they know of. That duty falls on the licensee, so a defect you tell your realtor about is one they must disclose. Whether a particular problem counts as a material latent defect depends on the facts, so it is worth confirming with a lawyer.

Do I have to tell buyers my house is already conditionally sold?

RECA states that a seller has no obligation to disclose to potential buyers that the home is conditionally sold when accepting offers. That exception is specific and does not extend to defects.

Do missing permits count as something I should disclose?

RECA's bulletin gives lacking the appropriate building or other permits as an example of a defect that is more than physical. Talk to your realtor and a lawyer about how it applies to your property.
