Short answer. No. A contract of deposit covers movable things only, so you cannot leave a lot or a house with someone for safekeeping the way you leave a bag or a document. Arrangements over land go under other contracts, and a court-ordered judicial deposit is the one exception.
What the law says
Only movable things may be the object of a deposit.
Civil Code, Article 1966 — Only Movables. Read the full provision →
What a deposit is, and why land does not fit
A deposit is the arrangement where you hand a thing over to someone whose whole job is to keep it safe and give it back. Custody is the point of it, not use. That shape assumes an object which can be delivered, put away, and returned — a sealed box, jewellery, a car, a bundle of documents. Land cannot be delivered in that sense and cannot be handed back; it stays exactly where it is whoever holds the keys. So the Code draws a bright line at movables rather than asking case by case whether custody of an immovable is possible. The rule is short because it admits no argument.
Calling it a deposit does not make it one
This matters more than it looks. People do leave houses, farms and vacant lots in the hands of relatives, caretakers and neighbours while they work abroad or wait out a family dispute, and the paper they sign sometimes says deposit. The label does not control. A court looks at what the parties actually agreed to do, and it will not apply the depositary's duties to something the Code says cannot be a deposit at all. The practical risk is that a person who thought he had strict safekeeping obligations running in his favour discovers he has an unwritten caretaking arrangement with far weaker terms.
What to use instead
Choose the contract that matches what you actually want. If someone is to manage the property, collect rents, pay taxes or deal with tenants on your behalf, that is an agency, and a written special power of attorney should spell out exactly which acts are covered. If someone is to live in or use the property for free and return it, that is a free loan of a thing, which can cover a house. If he is to pay for the use, it is a lease. If your concern is only that the place is watched and maintained, a caretaker arrangement with defined duties, a defined term and a stated allowance is clearer than any borrowed label.
The court-ordered exception
There is a second kind of deposit that does not arise from anyone's agreement: judicial deposit, or sequestration, which a court orders over property that is the subject of litigation so that it is preserved while the case runs. That form is not confined to movables — immovable property may be placed under it — and the depositary answers to the court rather than to either party. It is not something you can arrange privately by writing the word into a contract. It follows a court order in a pending case, and the property is released on the court's terms, not on the demand of the person who owns it.
