Building permits in Sicily: CILA, SCIA and what they mean in practice – to avoid disputes with contractors
Before you start, align documents, scope and priorities. That alone prevents most late changes and cost overruns. In Sicily, coastal exposure and mixed building stock make early checks even more important.
Permits and documentation
Choose the correct route (CILA, SCIA or permit) based on the scope and the building context.
Check constraints and approvals (heritage, landscape, condominium) before appointing contractors.

- How to document decisions
- How to keep changes under control
Where to start
Commission an accurate measured survey and clear drawings: without reliable measures, design is guesswork.
Collect the key documents (permits, drawings, cadastre) and check consistency between existing condition and authorised state.
- Documents you should have
- How to keep changes under control
- Questions to ask contractors
Technical details that matter
Verify material compatibility with substrates, especially near the coast where salt air accelerates decay.
Focus on critical junctions (waterproofing, thermal bridges, services) because most post-handover issues start there.
- Constraints to check early
- Questions to ask contractors
- How to document decisions
- You need a quick technical check before buying or signing.
- You must confirm the right permit path and missing documents.
- You want measurable specs to compare quotes properly.
- You started works and need to regain control of scope and changes.
- Mixing up cadastre updates and building permits (they are different).
- Ignoring waterproofing, slopes, ventilation and other “small” details.
- Applying standard solutions without reading the building context.
- No clear responsibilities between client, contractor and designers.
