The building permit: the authorisation for major transformations
Summary
TAV. 00The authorisation required for the most significant transformations: new construction, urban restructuring and 'heavy' building renovation. Governed by art. 10 of D.P.R. 380/2001, it is an express measure issued by the Municipality and, as a rule, onerous (construction contribution).
Scope of application
TAV. 01It is required for the works listed in art. 10 of D.P.R. 380/2001. For some of them the SCIA alternative to the permit (art. 23) is allowed instead. Minor works follow the CILA or the SCIA. The detailed rules may be supplemented by regional laws.
In depth
TAV. AThe 'heavy' title: when the permit is needed
The building permit is the authorisation required for the works with the greatest impact on the territory: new construction, urban restructuring and 'heavy' building renovation — the kind that leads to a wholly or partly different building, with added units, changes in volume or, for constrained properties, in shape and elevations. It is governed by art. 10 of D.P.R. 380/2001 and is the heir of the old building concession.
How it is obtained: an act, not a self-certification
The procedure is express and examined: the application is filed with the design, a responsible officer examines the file, may request integrations only once and drafts a proposed decision. The permit is issued within defined terms; for unconstrained properties, once the terms expire, silence-assent may apply.
- 01ApplicationFiling the application with the design and the title of entitlement (ownership or other right).
- 02ExaminationThe responsible officer examines the file and may request integrations only once.
- 03AssentsDraft decision and acquisition of the necessary assents (e.g. landscape authorisation).
- 04IssueIssue of the permit and payment of the construction contribution; absent constraints, silence-assent may apply.
Validity, derogations and variants
Works must start within one year of issue and finish within three, save extension; once the terms expire, the unbuilt part requires a new title. The law provides particular forms: the permit in derogation from the planning instruments (art. 14) for works of public interest, and the agreement-based permit (art. 28-bis) when the works require obligations governed by an agreement.
| Aspect | In brief |
|---|---|
| Nature | an express measure: the authority issues an act |
| Works | new construction, urban and heavy renovation |
| Cost | onerous: construction contribution (save exemptions) |
| Validity | start within 1 year, finish within 3 years |
| Alternative | SCIA alternative to the permit (art. 23) for some works |
Why it matters
The building permit is the threshold beyond which transforming the territory requires the community's active assent, not just a technician's sworn statement. It is the heaviest title — in examination, cost and liability — and marks the boundary between what a private party may declare and what the Municipality must authorise.
Key points
TAV. K- Authorisation for the highest-impact works: new construction, urban and heavy renovation (art. 10 D.P.R. 380/2001).
- It is an express measure: the Municipality assesses and issues an act; the professional's self-certification is not enough.
- As a rule onerous: it entails the construction contribution (urbanisation charges + construction cost).
- Validity: works started within 1 year and completed within 3, save extension.
- For some works it can be replaced by the SCIA alternative to the permit (art. 23).
Frequently asked questions
TAV. QWhen is a building permit needed rather than a SCIA?
For new construction, urban restructuring and heavy building renovation. The SCIA covers minor works and light renovation; for some heavy works the SCIA alternative to the permit may be chosen.
Is the building permit subject to payment?
As a rule yes: it entails the construction contribution (urbanisation charges and construction cost). The law, however, provides cases of reduction or exemption (for example some public works or agricultural building).
How long does the building permit last?
Works must start within one year of issue and finish within three, save extension. Once the terms expire, the unbuilt part requires a new title.
What is silence-assent on the permit?
For unconstrained properties, if the Municipality does not act within the terms, the application is deemed granted. It does not apply where other authorities' assents are required, such as the landscape constraint.
What are the permit in derogation and the agreement-based permit?
The permit in derogation (art. 14) allows, for works of public interest, to derogate from the planning instruments by municipal council resolution. The agreement-based permit (art. 28-bis) is used when the works require obligations (works, transfers) governed by an agreement.
