Completed new construction: mandatory documents in the Registry in 2026

Key data

If you have an old building that you want to register as completed new construction in the Property Registry, this resolution directly affects you. The DGSJFP resolved in June 2026 an appeal filed by a notary in Oviedo against the negative qualification of the Property Registrar of Oviedo no. 5, which had suspended the registration of completion of new construction for four defects.

The result is a clear delimitation of which documents are truly mandatory and which are not, with relevant practical implications for any developer, self-developer or owner processing a declaration of completed new construction, especially in Asturias and in cases of building age.

What does this regulation establish?

The resolution analyzes four defects alleged by the registrar to suspend the registration. The most relevant points are:

The route of art. 28.4 of the TRLSRU allows registration of buildings for which the demolition or restoration of urban legality action has already prescribed. It is the usual mechanism for regularizing old buildings that were built without a license or without completing the registration process.

The art. 202 of the Mortgage Law requires that when declaring new construction, the georeferenced graphic representation of the building be incorporated. The resolution clarifies that this requirement is limited to the building's footprint on the ground, not the entire registered property.

Economic and operational impact

The reduction in documentary burdens has a direct economic impact for owners and developers:

• Partial georeferencing: Preparing the graphic representation of an entire plot can cost significantly more than georeferencing only the building footprint. This clarification can reduce the fees of the technician responsible for georeferencing.
• Building Book: Its preparation involves collecting technical documentation, plans and manuals for use and maintenance. In old buildings, this document may be difficult or impossible to obtain. By not being required via art. 28.4 TRLSRU, an obstacle that in practice blocked many registrations is eliminated.
• Energy efficiency certificate: Its obtaining requires the intervention of a qualified technician and has a variable cost depending on the property's area. By not being mandatory in cases of building age, this procedure and its associated cost are saved.
• Reduction of resources and litigation: The registrar's negative qualification generated an appeal to the DGSJFP, with the costs of time and advice that this entails. A clear interpretation of requirements avoids these situations.

Who does it affect?

• Owners of old buildings who want to register or regularize their property in the Property Registry.
• Self-developers who declared the work under construction and are now processing completion.
• Real estate developers with assets pending registration by completion of work.
• Notaries who authorize deeds of declaration of completed new construction, especially when using the route of art. 28.4 TRLSRU.
• Property registrars, who must adjust their qualification criteria to this DGSJFP doctrine.
• Legal and real estate advisors who accompany clients in property regularization processes.

Although the specific case refers to the Property Registrar of Oviedo no. 5, the DGSJFP doctrine is of general application throughout the national territory.

Practical example

A self-developer in Asturias declared the construction of his single-family home as "work under construction" in the Property Registry. Years later, he wants to register the completion of the work. The registrar requires him to provide: (1) georeferencing of the entire plot, (2) the Building Book and (3) the energy efficiency certificate.

Since the building is more than ten years old and the demolition action has prescribed, the notary uses the route of art. 28.4 of the TRLSRU. Following the doctrine of this DGSJFP resolution:

• Only the georeferencing of the building footprint must be provided, not the entire plot, which reduces the cost of technical work.
• The Building Book is not required via this route, eliminating a procedure that in an old home may be unfeasible.
• The energy efficiency certificate is also not mandatory in this case of building age.

The result: the registration can be completed with less documentation, less cost and in less time, avoiding an appeal to the DGSJFP like the one that originated this resolution.

What should owners and developers do now?

1. Identify if your case fits art. 28.4 TRLSRU: If the building is more than ten years old (or the applicable prescription period in your autonomous community) and there is no active urban discipline proceeding, you can use this route to register the completion of work.
2. Only commission georeferencing of the building footprint: It is not necessary to georeference the entire plot. Communicate this to the technician preparing the graphic representation to avoid unnecessary costs.
3. Do not provide the Building Book if you use the route of art. 28.4 TRLSRU: This DGSJFP resolution confirms it. If the registrar requires it, you can invoke this doctrine.
4. Verify if the energy efficiency certificate is required in your specific case: In cases of building age via art. 28.4 TRLSRU, the resolution analyzes and rules out its mandatory nature. Consult with the notary before commissioning it.
5. In case of negative qualification, appeal with grounds: If the registrar suspends the registration for any of these reasons, this DGSJFP resolution is the direct legal argument to appeal. The notary can file the appeal with the General Directorate.
6. Seek advice from a notary or lawyer specialized in property law: Each case has particularities (autonomous community, type of building, urban situation) that can modify the applicable requirements.
