The job contract is the act by which the entrepreneur commits to the purchaser-owner of the land to carry out the construction of a building for a fixed price that the purchaser is obliged to pay him.
Like the preliminary contract, the job contract must include information on the parties, their obligations, and the sale price. Unlike the preliminary contract, the business contract will be signed only if you own the land on which the building is built or to be built.
Preliminary contract or job contract?
You cannot sign the preliminary contract and then a job contract. Therefore, when the contractor is the owner of the land and building, he must offer you a preliminary contract. However, when you are the owner of the land on which the building is or will be built, you must sign a job contract.
The preliminary contract only applies if the land and the building belong to the builder.
