For any construction or demolition project, the DTAC (Technical Documentation for the Building Permit) or DTAD (Technical Documentation for the Demolition Permit) represents the mandatory documentation that the architect and design team must prepare before submitting the application to the town hall. This ensures that the project complies with current urban planning and technical regulations.
The Main Steps to Obtaining a DTAC/DTAD
1. Collecting Initial Documentation
- Property deed and an updated Land Registry excerpt;
- Zoning certificate;Cadastral plans and site plan;
- Preliminary approvals, if the land is located in protected areas or requires special agreements.
2. Analyzing the Land and Regulations
- Verifying urban planning indicators: POT, CUT, setbacks, and height regime;
- Determining the required permit type and any additional approvals.
3. Developing the Technical Design Package
For DTAC: The project includes architectural plans, structural design, MEP engineering layouts, and the necessary details for permitting;
For DTAD: The plans and technical documentation required for demolition, along with potential structural reinforcement or remodeling works.
4. Obtaining Approvals and Agreements
- Depending on the project type, environmental approvals, water-sewage utility connections, fire safety (ISU), historical heritage/cultural approvals, or other authority clearances may be required.
5. Reviewing and Completing the Documentation
- All plans and documents are thoroughly reviewed for compliance;
- The final application file is assembled for town hall submission.
6. Submitting the Application to the Town Hall
- The complete DTAC/DTAD file is submitted along with the application form for the building or demolition permit;
- The local authority reviews the documentation and may request clarifications or additional information.
7. Issuance of the Permit
- Following the review of the file, the town hall issues the building or demolition permit;
- The DTAC/DTAD remains the official reference document throughout the execution of the works.
