Obligation of Certificate of Static Suitability
The Certificate of Static Suitability is a document that attests to the stability of the load-bearing structure of a building The CIS is required to obtain the habitability of a building, especially when the inspection certificate is missing. It also delves into the validity of the certificate and the cost of obtaining it.
Certificate of Static Suitability: what is needed and when it is mandatory
What is the Certificate of Static Suitability?
The Certificate of Static Suitability, also known as CIS, is also known as a structural safety certificate, and is a key document attesting to the stability of a building’s load-bearing structure. This certificate is issued in accordance with the laws in force at the time of construction, with special reference to earthquake-resistant regulations, such as Ministerial Decree 15/05/1985 and Ministerial Decree 20/09/1985.
What is the Static Suitability Certificate for?
CIS is required to obtain the fitness of a building, especially when the static inspection certificate under Law 1086/71 is missing. In Milan, this certification is required for all buildings over 50 years old. Obtaining CIS is essential to ensure the structural safety and suitability of a building for occupancy.
When a Certificate of Static Suitability is mandatory
As we said, it is a document that certifies the stability of a building’s structure. It becomes a fundamental requirement when, in the case of an application for condonation, the works referred to (i.e., those portions built illegally) exceed 450 cubic meters of volume.
Contents of the Certificate of Static Suitability
The verification of static suitability required to obtain CIS is based on two levels of investigation:
- Level One: Involves a qualitative analysis of the building, assessing the load-bearing structures, materials used, soil conditions, and the presence of signs of any disruption such as cracks or lesions.
- Second Level: A more in-depth security audit is implemented when there are risk situations that emerged during the first investigation. This phase involves experimental and/or analytical instrumental investigations to define reinforcement or consolidation interventions.
Validity of the Certificate of Static Suitability
The validity of the CIS varies according to the outcome of the first level verifications:
- Positive Outcome: Has a maximum validity of 15 years from the date of issue.
- Situations of Risk: If situations of risk are noted for accessory elements and non-load-bearing structures, the CIS is issued “with prescriptions” and is valid for two years. This period is granted to secure the parts at risk. If amnesty is carried out, the CIS will be valid for another 13 years; otherwise, it will lapse along with habitability.
Costs of the Certificate of Static Suitability
The cost of CIS depends on several factors, including the type of building, maintenance conditions, and context characteristics. On average, it is around 2,000-3,000 euros, plus VAT and taxes. Price may vary depending on the need for load testing.
Conclusions
The Certificate of Static Suitability is an essential document to ensure the structural safety of buildings. Its obtainment is regulated by precise regulations, and its validity is linked to the conditions found during audits. Obtaining CIS is a key step in ensuring the stability of buildings over time.
