Buying · Latent defect · Pool
Buying a house with a pool in winter means buying equipment you will not see running for six months. That is a textbook latent defect situation, and it can be prepared for.
An inground pool is almost always sold closed, under a cover, between October and May. The buyer sees neither the structure, nor the plumbing, nor how the pool actually behaves. That is exactly the context article 1726 of the Civil Code of Quebec was written for: the defect that could not be perceived by a prudent and diligent buyer without the need to resort to an expert. A leak in buried plumbing, a cracked structure under the liner, a filtration system out of service or a pool that does not meet safety regulations can all be latent defects. Conversely, a pool visibly at the end of its life, or whose condition was disclosed, surprises nobody. Seriousness is also assessed against what the pool represented in the price paid.
Because the season makes it invisible. Between fall and spring an inground pool is closed, the system is drained, the cover is on. A standard pre-purchase inspection usually does not cover pools, and even when it mentions one, it cannot put the pool into operation.
Article 1726 defines an apparent defect as one that can be perceived by a prudent and diligent buyer without the need to resort to an expert. On a closed pool, almost nothing meets that definition, which works in the buyer's favour.
The sequence is the same as for any latent defect. Document from the first fill: photos, water level readings, dates. Give written notice to the seller within a reasonable time, as article 1739 requires. Bring in a specialist before excavating, because once the trench is closed the original condition is gone. Then get a number and send the formal notice.
Watch the starting point of the deadlines: if discovery happens at opening in May, that is the moment that counts, not the date of the deed. Article 2926 provides that the period runs from the day the injury appears for the first time. See the latent defect deadlines.
Article 1726 requires a defect that renders the property unfit for its use or so diminishes its usefulness that the buyer would not have bought it or paid so high a price. A pool is rarely essential to living in a house, which sellers will argue. The buyer's argument sits elsewhere: the pool was part of the price paid, and an unusable basin reduces the value of what was bought. That is why quantifying matters so much here.
Usually not, or only superficially and out of season. Read the inspection contract: what is excluded from the mandate is written there. An exclusion actually reinforces the hidden character of the defect.
Non-compliance that forces work and that was neither detectable nor disclosed is analyzed as a defect. Check first whether it appeared in the municipality's file, which would make it perceivable.
A pool drained outside proper procedure can lift or deform. If that happened after the promise to purchase and caused damage, you are no longer in latent defect territory but in the seller's obligation to deliver the property in the condition it was in. Document the condition at the viewing and at possession.
The latent defect file: the four tests, the deadlines, the formal notice, the proof, the expert report, the six steps, small claims court, who pays, the seller who did not know, older homes, water infiltration, the roof, the inground pool and the septic system and the well.
