What happens if someone builds a house on my land in good faith?

The landowner chooses: keep the house, or sell the land

Article 448 of the Civil Code gives the landowner, not the builder, the choice of remedy when a house has been built on the land in good faith. The landowner may appropriate as his own the works — that is, keep the house — but only after paying the builder the indemnity the law provides for. Alternatively, the landowner may instead oblige the builder to buy the land outright. What the landowner cannot do is simply keep the house for free or order the builder to remove it, because Article 448 presumes the builder acted honestly, believing the land was theirs to build on.

There is a limit on forcing the builder to buy

The choice is not entirely one-sided. If the landowner wants to force a sale rather than pay for the house, the builder or planter cannot be obliged to buy the land if its value is considerably more than that of the building. In that situation, the builder instead pays reasonable rent for the land, with the terms set by agreement or, failing that, fixed by a court. This protects a builder who put up a modest house on land that turns out to be worth far more than the structure itself.

Why 'good faith' is the whole ballgame here

Article 448 only applies because the builder is presumed to have acted in good faith — genuinely, reasonably believing the land was theirs or that they had the right to build on it. A builder who knew the land belonged to someone else, or who ignored an owner's objection and built anyway, is not protected by this article and faces a much harsher set of consequences. Whether a builder's belief was honest and reasonable is a factual question, and it is often the first thing that needs to be sorted out before either side can act.

Do not take the law into your own hands

If you find a house standing on land you own, the instinct to tear it down or lock the builder out is understandable. The provision exists precisely to stop that. Where the builder acted in good faith, the landowner does not get to simply eliminate the improvement; the law channels the dispute into a choice — appropriate the building on paying the required indemnity, or oblige the builder to buy the land — and while that choice belongs to the landowner, it has to be exercised, not assumed. Acting outside the framework is what turns a property dispute into a far larger legal problem.
