In the past decades, Italian hygienic requirements for dwellings have been modified by multiple derogations. Aim of the present work is to analyse the derogations introduced at a national, regional, and local level. The most important derogations were related to the habitable use of semi-basements and garrets, and building restoration. The paper also describes the regulations regarding indemnity for infringement of building abuses. The authors underline the need for more uniformity and clarity in the determination of health standards of dwellings, as well as for a simplification of the existing legislation.
