According to the law for the amendment of art. 291 of Law no. 227/2015 on the Fiscal Code, the cap in this case changes from 450,000 lei to 140,000 euros. 
Thus, according to the text, the reduced rate of 5% is applied on the basis of taxation for the delivery of housing as part of social policy, including the land on which they are built. The land on which the house is built also includes its footprint. 
Housing delivered as part of social policy means: delivery of housing with a usable area of up to 120 square meters, excluding household annexes, whose value, including the land on which they are built, does not exceed 140,000 euros, equivalent to lei, excluding VAT, purchased by individuals. 

The usable area of the house is the one defined by the Housing Law no. 114/1996. The household annexes are those defined by Law no. 50/1991 regarding the authorization of the execution of construction works. The reduced rate applies only to homes that can be inhabited as such at the time of sale. (source:
