The cartea tehnică a construcției, the building’s technical logbook, was for a long time a folder that reached the owner and stayed there. Article 529 paragraph (1) keeps it as the documentation completed at handover, and the stages of handover are explained on the dedicated page.
Paragraph (2) changes what it is, though, not just what it looks like.
The format is no longer a choice
Article 529 paragraph (2) says it is mandatory to produce the logbook “în format electronic care se încarcă în Registrul Național al Construcțiilor”, in electronic format uploaded to the national construction register, a register that “va fi în permanență conectat” with the databases underlying the cadastre and the land book.
That is the structural part. The logbook is no longer a folder sitting with the owner that nobody looks at until something goes wrong. It becomes a record in a system tied to the land register.
Article 530 paragraph (9) says who uploads it: registration happens “prin grija beneficiarului”, through the client’s own effort.
Handover happens at two moments, not one
The detail easiest to miss in article 530 paragraph (2) is that delivery comes in two instalments.
At handover on completion, you receive the design documentation updated to that date and the execution documentation, letter a). At final handover, you receive the handover documentation, the in-service monitoring and interventions documentation, the user manual and the operating specifications, letter b).
Years can pass between those two moments. A contract that only says “the logbook is handed over at completion” does not cover the second instalment.
Who keeps it, by stage
During execution, updating happens “sub coordonarea dirigintelui de șantier”, under the site supervisor, paragraph (3). Producing it falls to the developer, paragraph (2). Keeping and updating it falls to the owner, paragraph (4). In owners’ associations, to the administrator, paragraph (6).
One reading, offered as such: paragraph (5) refers to “obligația prevăzută la alin. (3)” as resting on the owner and allows other beneficiaries to discharge it by contract. But paragraph (3) is the one about the site supervisor, and the owner’s obligation sits at paragraph (4). We read the reference as pointing to paragraph (4), because otherwise paragraph (5) has no object, but it is a reading, not a certainty.
The effect we think matters most
What follows is our view.
Paragraph (8) says that on sale, the logbook is handed to the new owner “în format fizic și digital”, in both physical and digital form, and that the new owner takes on the duty to keep it current.
That turns the logbook into an asset that transfers, rather than an end-of-site formality. And since the register is connected to the land book, its absence becomes, over time, visible at a sale.
The practical effect will not show in the first year. It shows at the building’s second transaction, when the buyer can check what they could not check before. We discuss the link with regularising existing buildings in our analysis of the one-year window.
What we are watching next
When the Registrul național al construcțiilor actually becomes usable for uploads by clients, and whether notaries start requiring proof of registration on sale. We have written about the platform timetable and about who signs the design. The section of the technical book almost nobody fills in is covered in the duty that starts after you move in.
