If the owner shall make extraordinary repairs, he has the right to demand of the usufructuary the legal interest on the amount invested in such repairs during the continuance of the usufruct.\nIf he shall not make them when indispensable for the maintenance of the thing, the usufructuary may make them; but he shall have the right to demand of the owner, at the end of the usufruct, the increase in value which the tenement may have acquired by virtue of such repairs.\nIf the owner refuse to pay the value thereof, the usufructuary has the right to retain the thing until he reimburses himself with the products thereof.\nHistory —Civil Code, 1930, § 430.
