Indoor environment is one of major health determinants, and the regulations that set the sanitary requirements are of primary importance for the protection of public health. The authors analyse the critical aspects of the complex Italian regulatory system, starting from the EU regulations, through national and regional laws, and finally the municipal regulations. They underline the need for more uniformity and clarity in the determination of health standards, as well as for a simplification of the existing legislation. Moreover, they highlight the importance of controlling and monitoring indoor environment, currently almost completely absent in Italy due to the effects of the regulatory changes of the latest years.
