Official cancellation of the SCIA, when the Municipalities can act in self-defense and when not. With an interesting ruling, the Council of State sets the limits of building control: reasons unrelated to the initiation of the procedure and restrictive interpretations that do not comply with general building regulations are illegitimate.
The point in sentence 05210/2026 which effectively binds the Municipalities to rigid assumptions of procedural transparency and regulatory coordination. In particular, “surprise” interventions, late protests and obvious misrepresentations of the primary legislation were blocked.

Municipalities and cancellation of the SCIA
The case addressed in the sentence concerned the no opposed by the Municipality to the SCIA presented for the recovery of an attic for residential purposes. The builder intended to recover the flat roof for residential use, through the implementation of internal works, consisting of the demolition of part of the floor slab, for a thickness of 28 cm, in such a way as to reach a floor height of 2.60 metres, and in the creation of window/french door spaces along the perimeter walls.
The administration had justified the ban on the works by raising a number of exceptions, which ranged from failure to comply with the minimum heights to the lack of documentation regarding the construction of the relevant car parks. In the second instance judgment, the Municipality’s position was confirmed. The judges of Palazzo Spada instead agreed with the builder, establishing specific interpretative principles which require the administration to behave rigorously when examining the SCIA.
No to the request for posthumous integration
The first pillar of the decision concerns compliance with the participation guarantees established by the art. 7 of law 241/1990 regarding administrative proceedings. The Council of State clarified that the final annulment provision cannot be based on critical findings that have not been previously stated in the communication initiating the proceedings.
In the case in question, in fact, substantial disputes relating to the adaptation of the thermal insulation (ex L. 10/91) and the documentary discrepancies in the stratigraphy of the slab had been raised by the Municipality only in the final deed. This modus operandi was judged illegitimate as it deprives the private individual and the designer of the possibility of counter-arguing or proceeding with a regular formal sanction during construction.
Limits of local building regulations compared to regional law
A second important profile concerns the hierarchical relationship between the regulatory sources. The Building Regulations of the Municipality of Milan (art. 114, paragraph 16) made the presentation of the SCIA conditional on the prior filing of the registered and transcribed notarial deed relating to the relevance of the parking spaces.
The Board noted the irrationality of this provision with respect to the primary law (art. 64, paragraph 3, of LR Lombardia no. 12/2005). In fact, the regional law provides for the right to resort to the monetization of parking spaces if the technical investigation demonstrates the impossibility of finding suitable spaces. Demanding the stipulation and early transcription of the notarial deed denies the very nature of the preliminary investigation procedure and violates the principle of procedural simplification.
No to restrictive assessments of heights in attics
The ruling also offers a textual clarification regarding the minimum habitability requirements. The municipal administration had contested the non-compliance of the project since it envisaged an internal height of the rooms equal to 2.60 metres, compared to the parameter of 2.40 meters indicated by the art. 63, paragraph 6, of LR 12/2005.
The Council of State rejected the restrictive interpretation of the Municipality, reiterating that the measurement of 2.40 meters constitutes a mandatory minimum requirement for the admissibility of the recovery, and consequently the private individual is fully permitted to configure higher quotas, aimed at guaranteeing better healthiness and habitability of the premises.
Finally, even the disputes relating to the documentation on the methods of disposal of waste materials have been declared unsuitable for establishing self-defense: if the private individual declares compliance with Legislative Decree 152/2006, the verification of actual compliance is up to the local authority only upon final assessment, at the conclusion of the works.
General framework of self-protection on SCIA: powers and limits of the Municipalities
Let’s see a summary table of the Municipality’s limits on the annulment of the building SCIA:
|
The Municipality CANNOT cancel the Trail |
The City MAY cancel the Trail and order demolition |
|---|---|
|
Procedural defects (Surprise effect): If you insert new technical objections directly into the final provision, omitting them in the communication starting the proceedings. |
False declarations: If he finds false statements, malicious omissions or untruthful and decisive declarations in the graphs or in the state of fact. |
|
Formal or documentary irregularities: If these are merely documentary discrepancies, graphic errors or deficiencies that can be easily remedied or integrated during construction. |
Substantial and incurable abuses: If the intervention manifestly and structurally violates the general urban planning indices, intended uses or area constraints. |
|
Deferred posthumous checks: If you require compliance (e.g. effective tracing of the rubble or acoustic requirements) which can be verified by law only once the construction site is completed and the final balance has been taken. |
Lack of minimum requirements: If the property does not comply with the minimum and mandatory hygiene-sanitary and habitability parameters set by law (e.g. heights lower than the minimums). |
|
Contrast with primary sources: If it applies internal municipal building regulations that limit or conflict with the faculties granted by regional or state law (e.g. exclude monetization). |
Legal deadlines and public interest: If it intervenes by motivating a current and concrete public interest, notifying the provision within the maximum deadlines established for self-defense. |
