ITE, IEE and the energy certificate: the levy that is coming and the bill you will pay

A building over 50 years old must have passed a technical inspection. If it has not, or passed with elements in the worst grade, a special levy is on its way that the seller knows about and the listing does not mention. Some regions publish it; for the rest, you ask.

The technical inspection (ITE / IEE)

National land law requires the Building Evaluation Report (IEE) for residential buildings over 50 years old; the Basque Country has its own ITE (Decree 117/2018) with a public register; Catalonia the ITE with a certificate of fitness; Madrid and other cities municipal registers; the Valencia region the IEEV.CV, published per building. The inspection grades the elements (structure, façade, roof, services); grade 4 means urgent intervention.

What you look for: whether the ITE was compulsory and has been filed; its date and validity; the worst grade; whether there is a use-and-maintenance plan. "Not yet required" (young building) is also an answer.

The energy certificate (CEE)

Compulsory to sell or let since 2013; registered with the regional authority with a consumption letter (A–G) and an emissions letter. Catalonia, the Valencia region, Andalusia and the Basque Country publish the registers as open data; with the cadastral reference you can see the letter and date. An E or F on a 90 m² flat is several hundred euros a year against a C — and a renovation pending if European rules go the way they are heading.

What is in no register at all

Community debts, approved and pending levies, the reserve fund. There is no public register: the only valid document is the community debt certificate the seller must bring to the notary (the buyer is liable for the due part of the current year and the three previous). Also ask for the minutes of the last three meetings: that is where the levy that was approved and the one being discussed live.

What the PropVer report does

It matches the building against the Basque ITE register and the IEEV.CV (Valencia region): whether required, filed, date, validity, worst grade, maintenance plan; against the open energy-certificate registers (letter and date) where they exist; and closes with the list of documents that are not public and you must request before signing.
