According to art. 6 of RD 235/2013
For individuals, notaries and real estate agencies, we issue the Energy certificate of their properties, in accordance with European legislation, as a qualified technician.
The habitability certificate is the document that certifies that a dwelling, local or residential building, meets the minimum surface conditions, hygiene and has adequate facilities to house people.
The Livability Certificate is a mandatory document for housing occupancy and cannot be definitively contracted for water, electricity, gas or any other energy or telecommunications product if the dwelling, the premises or the residential building do not has the valid habitability certificate.
