Site acquisition, demolition permits and redevelopment rules in Milan

Planning Framework and Development Density

Redevelopment projects in the Municipality of Milan (*Comune di Milano*) are governed by the local land-use plan, known as the *Piano di Governo del Territorio* (PGT). The PGT consists of three distinct components: the *Documento di Piano* (strategic vision), the *Piano dei Servizi* (public infrastructure standards) and the *Piano delle Regole* (binding zoning regulations).

Within the Consolidated Urban Fabric (*Tessuto Urbano Consolidato* or TUC), which covers most of Milan's built environment, the PGT establishes a uniform base building density index (*Indice di edificabilità Territoriale unico*) of 0.35 square metres of Gross Floor Area (*Superficie Lorda* or SL) per square metre of land site area. Developers can increase density above this baseline up to a maximum index of 0.70 sqm/sqm. To achieve this higher density, developers must acquire building rights (*diritti edificatori*) through the municipal urban equalization scheme (*perequazione edilizia*) or fulfil specific municipal targets, such as incorporating Social Residential Housing (*Edilizia Residenziale Sociale* or ERS).

Existing building volume (*consistenza edilizia*) on a tear-down site is generally preserved as a vested right. If an existing building exceeds the baseline 0.35 sqm/sqm index, the developer can retain the entire pre-existing SL upon demolition and reconstruction, subject to spatial design and environmental rules. Calculate buildable area by auditing historical building permits (*licenze edilizie*, *concessioni edilizie*) at the municipal archive (*Archivio Disegni del Comune di Milano*) to verify the lawfully established gross surface area before filing plans.

Permitting Categories for Demolition and Reconstruction

Under national construction law (*Testo Unico dell'Edilizia*, D.P.R. 380/2001), site works involving demolition are categorized based on structural changes, scale, and spatial impact.

Complete demolition of an existing building followed by reconstruction is classified under Article 3 of D.P.R. 380/2001 as either major building renovation (*ristrutturazione edilizia*) or new construction (*nuova costruzione*). If the new building maintains the exact volume, footprint (*sedime*), height and envelope of the original structure, it qualifies as *ristrutturazione edilizia*. In such cases, the work can proceed via a Certified Report of Commencement of Activity replacing a permit (*SCIA alternativa al Permesso di Costruire*) under Article 23 of D.P.R. 380/2001.

Where the project involves total demolition and subsequent reconstruction with changes to the footprint, height, or increased volume, it falls under *nuova costruzione* or heavy renovation. This requires a formal Building Permit (*Permesso di Costruire*) issued by the municipal One-Stop Shop for Building (*Sportello Unico per l'Edilizia* or SUE). Pure demolition without immediate reconstruction (*demolizione senza ricostruzione*) also requires a *Permesso di Costruire* or a heavy *SCIA*, along with a site management and waste removal plan complying with regional environmental regulations.

Heritage and Environmental Restrictions

Before undertaking demolition in Milan, developers must check for two primary statutory protections: historic-architectural heritage restrictions (*vincoli culturali*) and landscape constraints (*vincoli paesaggistici*).

Heritage protection is regulated by the Cultural Heritage Code (*Codice dei Beni Culturali e del Paesaggio*, D.Lgs. 42/2004). Under Article 10 and Article 12 of D.Lgs. 42/2004, any property owned by a public body or non-profit entity that was constructed more than 70 years ago is automatically subject to temporary heritage protection. A tear-down cannot occur unless the developer or owner obtains a formal verification of cultural interest (*Verifica dell'Interesse Culturale* or VIC) from the regional delegate of the Ministry of Culture, issued through the *Soprintendenza Archeologia, Belle Arti e Paesaggio per la città metropolitana di Milano*. If the Soprintendenza issues a negative declaration, the protection is removed, allowing demolition. If declared of cultural interest, demolition is prohibited.

For privately owned structures, heritage protection applies if the Ministry of Culture has formally served an individual declaration of cultural interest (*dichiarazione di interesse culturale*) under Article 13 of D.Lgs. 42/2004. Furthermore, the PGT's *Piano delle Regole* identifies historic settlements known as Nuclei of Ancient Formation (*Nuclei di Antica Formazione* or NAF). Within NAF zones, demolition of historic facades and structures is strictly regulated, often limiting intervention to conservative restoration (*restauro e risanamento conservativo*).

If the site is located near historic watercourses (such as the Navigli) or designated green belts, landscape protection under Part III of D.Lgs. 42/2004 applies. In these areas, demolition and reconstruction require a prior Landscape Authorization (*Autorizzazione Paesaggistica*) issued by the Municipality of Milan after consultation with the local landscape committee (*Commissione per il Paesaggio*).

Vacant Possession and Existing Tenancies

Site acquisition frequently involves existing residential or commercial tenants. Italian law provides statutory protections that govern lease termination and financial compensation.

Commercial leases are governed by Legge 392/1978. Commercial contracts have a mandatory minimum term of 6 years (9 years for hotel properties), renewing automatically for a secondary period. Under Article 29 of Legge 392/1978, a landlord may deny renewal at the end of the first 6-year period if the building must be demolished or fully redeveloped to comply with urban planning schemes. The landlord must give the tenant at least 12 months' formal written notice (18 months for hotel operations). Under Article 34 of Legge 392/1978, evicting a commercial tenant for redevelopment triggers a mandatory goodwill indemnity (*indennità per la perdita dell'avviamento*) equal to 18 months of the last agreed monthly rent (21 months for hotels). If the site is subsequently re-let for a similar commercial activity within one year, this indemnity doubles.

Residential leases are regulated by Legge 431/1998, which sets standard terms of 4+4 years or 3+2 years. Under Article 3 of Legge 431/1998, a landlord may refuse lease renewal at the end of the initial 4-year or 3-year period if the building is severely damaged, requires structural reconstruction, or is scheduled for complete demolition under an approved urban plan. The landlord must serve written notice at least 6 months prior to the expiration date. Unlike commercial leases, there is no statutory cash indemnity for residential tenants under national law, but failure to execute the declared works within 12 months obliges the landlord to reinstate the lease or pay compensation up to 36 months' rent.

Construction Contributions, Fees, and Timelines

Securing a *Permesso di Costruire* in Milan requires paying a municipal construction contribution (*contributo di costruzione*) pursuant to Article 16 of D.P.R. 380/2001 and Regional Law L.R. 12/2005. This contribution comprises two main charges: primary and secondary urbanization fees (*oneri di urbanizzazione primaria e secondaria*) and a construction cost fee (*costo di costruzione*). Rates are calculated based on gross floor area, intended land use (residential, commercial, office), and urban zone. For abandoned or degraded buildings (*edifici dismessi*), the Municipality of Milan applies specific fee adjustments or surcharges depending on location and project parameters set out in Council Resolution n. 28/2023.

Under Article 20 of D.P.R. 380/2001, the statutory review window for the SUE to grant or refuse a *Permesso di Costruire* is 60 days from application submission, extended to 120 days for complex redevelopments. However, when statutory clearings are needed from external authorities, such as the *Soprintendenza* (which has up to 90 days for landscape or historic reviews) or the regional fire service (*Vigili del Fuoco*), the timeline extends. Realistically, developers should budget 6 to 12 months to secure a *Permesso di Costruire* for a standard tear-down project in Milan, and 12 to 18 months if the site requires landscape clearances or a formal master plan (*Piano Attuativo*).

This guide outlines the legal and regulatory framework in force in Milan as of 2026. Developers and buyers should verify site-specific constraints directly with the *Sportello Unico per l'Edilizia* before committing capital.
