[Exceptions to hygienic requirements of dwellings in building restoration and indemnity for abuses in Italy].

Building restoration represents a fundamental tool to combine the population needs for housing with soil saving. Old buildings offer great possibilities, if we consider that 20% of residential buildings in Italy have been constructed before the beginning of XX century. In order to understand the public health impact of exemptions from hygienic requirements of dwellings, as well as indemnity for abuses, the authors analyse the national legislation on this topic. There is a strong need to update health standards and to rationalize and simplify the regulations, as a fundamental tool for the protection of public health in indoor environment.
