The legislation aims to simplify the bureaucratic procedures for citizens who want to do building work on their properties.
It also, among other things, enables owners to have small-scale illegal building work pardoned and increases the scope for renovations to create studios.
The law also makes it easier to change the official purpose that a property can be used for, whether it be a home or a place of business, etc.
The decree got the definitive green light with 106 votes in favour, 68 against and one abstention.
Salvini described it as “a common-sense decree that regularises small renovations, freeing council offices of millions of construction cases and restoring full use of the properties to the legitimate owners”.
Salvini stressed that the measure is not a full-blown amnesty on illegal building work, which Italy has had many of in the past.
In part it aims to raise revenues by getting property owners to pay to have the illegal works pardoned.
Critics say such measures encourage illegal building work.
