The first paragraph of article L. 145-34 is worded as follows:
“Unless there is a significant change in the items mentioned in 1° to 4° of article L. 145-33, the rate of change in the rent applicable when the lease to be renewed takes effect, if its term does not exceed nine years, may not exceed the change in a quarterly local index measuring the cost of construction that has occurred since the rent for the expired lease was initially set. This index is calculated under conditions determined by order of the State representative. In the absence of a contractual clause fixing the reference quarter for this index, it is appropriate to take into account a variation in the quarterly local index measuring the cost of construction fixed for this purpose by the aforementioned order. “
