The autorizație does not end on the day you collect it from the counter. The Cod asks you to give notice twice, at each end of the site works, and the two notices do not go to the same people.
At the start: two destinations, not one
Article 278 paragraph (3) says who notifies and whom: the holder of the autorizație de construire notifies the authority that issued it and the Inspectoratul de Stat în Construcții of the date works begin. The only exception is for institutions in the national defence, public order and national security system.
Two recipients, one notice. This is where it most often goes wrong, because the primărie is the body you have been dealing with for months, while I.S.C. appears only now, at the end of the process.
Paragraph (4) settles the form: the notice is sent in digital or written format. There is no requirement to appear at a counter.
The project goes with it
Paragraph (5) is the part nobody associates with a notice. Together with the start notification, the holder, through the chosen specialist designer, uploads into the Registrul Național al Construcțiilor, electronically signed, two things: the proiect tehnic de execuție with its referate de verificare, and the autorizație together with the avize and acorduri obtained.
Note who does the uploading: the chosen specialist designer, not the beneficiary. If nobody is designated for that step when you send the notice, the notice goes out and the duty stays unfulfilled. What the register is, and who else writes into it, is covered separately in the Registrul național al construcțiilor.
Also at the start, paragraph (6) requires the panou de identificare a investiției in a visible place, at the latest on the day works begin. Its content is set by ministerial order.
At the end: a single recipient
Here the scheme changes. Article 280 paragraph (10) requires the holder to notify the issuing authority of the date works were finished, again in digital or written form. I.S.C. is no longer your responsibility.
The reason is paragraph (11): the notified authorities forward to I.S.C., in electronic copy, the completion notice, the proces-verbal de recepție la terminarea lucrărilor, and the notice of the final value of the works. The route to I.S.C. exists, but it runs through the primărie.
What finished means
Paragraph (1) of the same article gives the definition, and it is stricter than people assume: works are considered finished if every element set out in the autorizație and in the proiect tehnic de execuție has been carried out and the recepție la terminarea lucrărilor has taken place.
Paragraph (8) closes the other route: buildings executed without an autorizație, or in breach of it, cannot be received, and those without a recepție are not considered finished. There is no version where you move people in and leave the paperwork for next year, and intabulare depends on that recepție.
Between the two moments sits a money duty. Paragraph (9): from the date works are finished until the recepție, the applicant must regularise, with the issuing authority, the value of the authorised works and the legal quotas owed. One of them is the I.S.C. quota.
The two dates are not the same date
The completion date and the recepție date are distinct, and article 280 uses them separately, in different paragraphs. The regularisation duty runs between them. Treat them as one moment and the regularisation has no interval to happen in.
The remaining steps, in the order the Cod asks for them, are in the order of steps, and what gets prepared before the first day on site is in five things before day one. The full permit procedure is on the page about the building permit.
Two envelopes, at two ends
Keep the short form: at the start you notify the primărie and I.S.C., and upload the project into the register through your designer. At the end you notify only the primărie, which passes the documents on. Everything else, regularisation included, hangs off those two dates.
