An off-plan buyer often hears both terms and assumes they mean the same thing — they do not, and knowing which is which matters before you complete.
Two different documents, two different authors
The Certificado Final de Obra (CFO) is a technical document signed by the project’s architect and technical site manager. It certifies that construction was actually completed according to the approved project and current building regulations. It comes from the construction professionals themselves, not from any public authority.
Where the town hall comes in
The Licencia de Primera Ocupacion (first occupation licence, or LPO) is a separate administrative permit, issued by the town hall, that confirms the finished building may legally be occupied and connected to permanent utilities. Our complete guide to the first occupation licence covers what buyers should check before completion and what happens if it is withheld.
The sequence: CFO first, then the licence
The CFO is a required document in the application for the first occupation licence. A town hall technician visits the finished building, checks it against that certificate and the originally approved plans, and only then issues the licence if everything matches.
Which one a buyer should actually rely on
As a buyer, the document that matters practically is the first occupation licence — it is what allows permanent water and electricity connections and confirms the town hall itself has verified the build. The Certificado Final de Obra is the technical groundwork behind that verification rather than something to rely on in isolation.

Frequently Asked Questions
What is the Certificado Final de Obra?
It is a technical document, signed by the project’s architect and technical site manager, certifying that construction was completed in line with the approved project and applicable building regulations. It is issued by the construction professionals, not by the town hall.
How is that different from the first occupation licence?
The Certificado Final de Obra is a technical certificate from the architects; the first occupation licence (Licencia de Primera Ocupacion) is a separate administrative permit issued by the town hall confirming the finished building may legally be occupied and connected to utilities.
Does one come before the other?
Yes — the Certificado Final de Obra is a required document you submit when applying for the first occupation licence. The town hall’s own technician then checks the finished building against that certificate and the approved plans before issuing the licence.
Which one do I actually need as a buyer?
You need the first occupation licence to be in place, since that is what allows permanent utility connections and confirms the town hall has verified the building matches what was approved. The Certificado Final de Obra is the technical paperwork behind that verification, not something you rely on separately.
What if the certificate and the licence do not match what was actually built?
If the finished building does not match the approved project — a changed layout, an extra unit, an encroachment — the town hall can withhold the first occupation licence until the discrepancy is resolved, whatever the Certificado Final de Obra says.
