L’edilizia economica e popolare costituisce un settore chiave per il perseguimento degli obiettivi delle politiche abitative italiane. L’assegnazione delle unità abitative avviene, in genere, mutuando l’istituto del diritto di superficie. Nel corso della durata della concessione, di frequente l’Ente concedente prevede la possibilità di riscatto della piena proprietà da parte del concessionario, a seguito del pagamento di un importo monetario. La Legge n. 448 del 23 dicembre 1998 definisce un criterio convenzionale per la determinazione del corrispettivo per la trasformazione del diritto di superficie in diritto di piena proprietà. Tuttavia, non di rado questo ammontare risulta totalmente avulso dal contesto mercantile di riferimento, generando fenomeni sperequativi per gli attori coinvolti (Pubblica Amministrazione e collettività interessate). Il presente lavoro mira a sviluppare e testare un approccio logico-deduttivo per la stima di un congruo valore di riscatto delle unità abitative concesse in diritto di superficie per un arco temporale determinato. Applicato a 106 città italiane, l’approccio metodologico proposto perviene alla determinazione, per ciascun ambito di studio, di un coefficiente moltiplicativo nella formula prevista dalla normativa che, contemperando le condizioni di mercato del contesto analizzato, garantisce un approccio equo e calibrato nel processo di stima del valore di riscatto. L’approccio metodologico messo a punto, implementato a diversi contesti territoriali, permette di avere contezza dei differenti coefficienti moltiplicativi, da traslare nella formula convenzionale definita dalla Legge n. 448/1998, a seconda della zona di interesse, in maniera da stimare il congruo corrispettivo da pagare per il riscatto di ciascuna abitazione.

Abstract
Affordable and social housing represents a key sector in the pursuit of the objectives of Italian housing policies. The allocation of housing units generally occurs through the application of the surface right institution. During the duration of the concession, the Public Administration (lessor) often provides for the possibility of redeeming full ownership by the leaseholder, upon payment of a monetary amount. The Italian Law No. 448 of 23 December 1998 defines a conventional criterion for determining the amount payable for the transformation of surface rights into full ownership. However, this amount is often entirely disconnected from the prevailing market context, giving rise to significant disparities between the Public Administrations and the involved communities. The present study aims to develop and test a logic-deductive approach for estimating the appropriate redemption value of housing units granted under surface rights for a fixed period. Applied to 106 Italian cities, the proposed methodological approach leads, for each study area, to the determination of a multiplicative coefficient to be used in the formula provided by the applicable regulation. This coefficient, by incorporating the market conditions of the analysed context, ensures a fair and calibrated approach in the estimation of the redemption value. The methodological approach, implemented across different territorial contexts, enables both public and private stakeholders to understand the various multiplicative coefficients to be incorporated into the conventional formula defined by Law No. 448/1998, according to the area of interest, in order to estimate the appropriate amount to be paid for the redemption of each housing unit.| File | Dimensione | Formato | |
