Regulation No.6 stipulates how buildings are to be used on the territory of Bulgaria and how you can receive permission to use a building. This permission is issued by the head of the Directorate of National Control of Construction (DNCC) or another person authorized by him and following a written application from the owner or from his independent construction supervisor, if he is authorized by the owner.

With finished buildings, the independent construction supervisor submits a report to the DNCC with attached co-ordination letters, permits and reviews from the authorized control state bodies according to type of building.

The request to obtain a permit or to have a State Sanctioning Commission formed to examine the building is made by the owner or the independent construction supervisor authorized by him. The request is then dealt with by the head of the DNCC or another person authorized by him and either issues an order within 10 days from date of the filed request. This order contains the grounds for the commission to be formed, the names of the commission chairman and members, their place of employment and position, the date, time and place of its meeting, and the period of time of its work which may not exceed ten working days. Upon submission of a justified report from the chairman and a subsequent sanction from the appointing body, the period of work of the commission can be extended to thirty working days. In urgent circumstances the commission has the right to terminate its work and make a protocol. The maximum duration of such a break will be defined by the appointing body. The work of the commission can be resumed once the causes of the break have been removed.

The application for a commission to be constituted must be filed together with:
1.A written request from the owner or the independent construction supervisor.
2.A permit to build.
3.A document of ownership or granted right to build.
4.An act confirming that the building (part or stage of it) complies with the requirements for it to be sanctioned.
5.A declaration stating that construction papers have not been cancelled or contested.
6.A report from the independent construction supervisor together with the papers pursuant from the appendices to Regulation No.6.
7.All co-ordination letters and appraisals from the authorized state bodies.
8.A proposal for persons to be appointed commission members.

The commission members are elected and appointed by the body issuing the order for a commission to be constituted.

Following the examination of presented papers, measurements and tests carried out on the building, opinions stated, the commission draws up a Protocol 16 to propose whether the permission to use the building may or may not be granted.

Within three days from the date of submission of the report from the independent construction supervisor and Protocol 16 (if necessary), the head of DNCC or another person authorized by him:
-issues the permit to use the building;
-refuses to issue such a permit and his refusal is supported by well grounded reasons.

Even though Protocol 16 may suggest that a permit to use the building should be issued, still the head of the DNCC or the person authorized by him might refuse to issue the permit to use the building when the case is subject to the provisions of Article 305, Para.1 of the Regulation for Application of the Law for Territorial and Settlement Planning (RALTSP).

When Protocol 16 suggests that a refusal to issue a permit to use the building should be adjudged, the head of DNCC may find the commission’s proposal inadequate, form a new commission and appoint new commission members. The head might decide against issuing a permit to use the building.

Objections to orders to constitute a commission or to refusals to constitute a commission, as well as to already issued permits to use the building or to refusals to issue such a permit can be filed within 14 days before the superior body in the hierarchy of DNCC, and when they have been issued by the Head of DNCC, objections must be addressed to the Minister of Regional Development and Planning.

Applications for permits may cover the entire building or parts of it, if the part(s) is/are good for independent use prior to completion of building.

The permit to use the building certifies that the building is appropriate to its purpose of use; that it conforms to the requirements for structural, environmental, fire, and sanitary and hygiene safety. The permit to use the buildings is then sent to the municipality for safe-keeping and as a part of the construction papers.

The permit will not be issued unless the owner or the independent construction supervisor has submitted the needed papers related to the building to the Cadastre office.
