Commissioning of a Construction Project

Commissioning of a construction project is the final legal stage of construction, after which the property is officially recognized as ready for use in accordance with the procedure established by law. The procedure depends on:

• the type of property;
• the method of construction;
• the consequence class;
• documents for the land plot;
• the construction passport or design documentation;
• documents granting the right to carry out construction works;
• whether the actually constructed property complies with the approved parameters.

As of 2026, construction projects are classified by consequence classes CC1, CC2, and CC3 rather than the former complexity categories I–V. Declaration-based procedures apply to projects with minor consequences, CC1, while commissioning of CC2 and CC3 projects is carried out by issuance of a certificate based on an act of readiness.

Before submitting documents for commissioning, it is important to review not only whether the building is physically complete, but also the entire legal history of construction: the land, the right to perform construction works, the design, technical characteristics, and any deviations.

Which Properties Must Be Commissioned

The procedure applies to completed construction projects where the construction works required formal authorization under applicable law. These may include:

• private residential houses;
• garden and country houses;
• apartment buildings;
• shops;
• offices and business centers;
• warehouses;
• industrial buildings;
• shopping centers;
• fuel stations;
• properties after reconstruction;
• other real estate properties.

At the same time, not every alteration inside premises constitutes separate construction requiring the same procedure, so the nature of the completed works must be assessed individually.

Commissioning of CC1 Projects

For projects with minor consequences, CC1, a declaration-based commissioning model is used. The Diia portal separately provides services for:

• registration of a declaration of readiness for a CC1 project;
• a declaration for a property constructed on the basis of a construction passport;
• certain special declaration-based procedures.

For properties constructed on the basis of a construction passport, the declaration may be submitted through the electronic cabinet; according to Diia, the service is free of charge and the registration period is up to 10 business days.

Commissioning of CC2 and CC3 Projects

A different procedure applies to projects with medium and significant consequences. Commissioning of CC2 and CC3 projects is carried out on the basis of an act of readiness by issuance of a certificate by the state architectural and construction control authority. To obtain the certificate, the following are submitted, among other things:

• an application for commissioning of the property and issuance of the certificate;
• an act of readiness of the property;
• other information and documents required under the applicable procedure.

An application for a certificate may also be submitted online through Diia using an electronic signature.

Documents Required for Commissioning

There is no single universal package for all buildings. The lawyer reviews:

• documents for the land plot;
• the cadastral number;
• the designated purpose of the land;
• urban planning conditions and restrictions, where required;
• the construction passport;
• design documentation;
• notification or permit for construction works;
• the technical passport;
• technical inventory results;
• the act of readiness for relevant properties;
• other documents depending on the type of construction.

It is especially important to check whether the area, number of floors, configuration, and other actual parameters correspond to the construction documents.

Technical Inventory and Technical Passport

Before completing the registration process, technical inventory is carried out for many properties. As a result, technical information is prepared regarding:

• the property area;
• the number of floors;
• the composition of premises;
• auxiliary buildings;
• the main technical characteristics;
• existing changes compared with previous documentation.

In the Diia system, technical inventory and issuance of a technical passport are also identified as a separate administrative service in the field of construction and real estate. If the inventory reveals significant deviations from the permit or design documentation, the method of legally resolving them should first be determined.

Commissioning of a Private House

For individual residential, garden, and country houses, the procedure depends on the documents under which construction was carried out. If construction was carried out on the basis of a construction passport, a declaration of readiness may be submitted after completion of the works. This service is officially available through the Diia portal. Before submission, it is necessary to check:

• the right to the land plot;
• the designated purpose;
• the construction passport;
• notification of commencement of works;
• the actual parameters of the house;
• the technical passport;
• the existence of extensions or alterations.

Commissioning of an Apartment Building

An apartment building requires a significantly larger set of documents and checks. Depending on its characteristics, it may fall within CC2 or CC3. The following are reviewed:

• design documentation;
• the right to carry out construction works;
• whether the completed works comply with the design;
• readiness of engineering systems;
• compliance with accessibility requirements;
• the act of readiness;
• documents of the construction participants;
• other requirements applicable to the specific property.

For relevant new residential and public buildings, updated civil protection requirements also apply in 2026 and should be taken into account at the design and construction stages.

Commissioning of Commercial Real Estate

For a shop, office, warehouse, restaurant, business center, or industrial property, it is important not only to commission the building but also to ensure that it is legally suitable for the planned activity. The following are analyzed:

• functional purpose;
• the land plot;
• the design;
• the consequence class;
• construction documents;
• utility networks;
• accessibility requirements;
• fire safety and other special requirements;
• subsequent licensing or permit procedures for the business.

What to Do If the Construction Differs from the Documents

A common problem is that the actual property does not correspond to what was provided for in the documents. For example:

• the area was increased;
• an additional floor was added;
• the configuration was changed;
• additional premises were constructed;
• the location of the house was changed;
• reconstruction was carried out instead of repair.

In such a situation, it is not advisable to immediately submit a declaration containing information that does not correspond to the actual condition. First, the lawyer together with technical specialists determines whether it is possible to:

• amend the construction documents;
• adjust the design;
• formalize the reconstruction;
• apply another procedure provided by law.

Unauthorized Construction and Commissioning

Not every unauthorized building can simply be “commissioned” through an ordinary declaration. It is necessary to establish:

• when the property was constructed;
• on which land plot it is located;
• whether the designated purpose of the land is appropriate;
• the type of building;
• which construction documents existed or were absent;
• whether there is a court decision;
• whether the property falls under a special commissioning procedure.

Diia separately provides declaration services for certain individual houses and CC1 agricultural buildings constructed without an authorization document, as well as for unauthorized properties where ownership has been recognized by a court decision. These are separate procedures and not a universal mechanism for legalizing any unauthorized construction.

What to Do If Commissioning Is Refused

Problems may arise due to:

• an incomplete set of documents;
• errors in the declaration;
• discrepancies between registers;
• non-compliance of the actual property with the documentation;
• problems with land rights;
• deviations from the design;
• failure to comply with mandatory requirements;
• inconsistencies in the act of readiness.

The lawyer reviews the grounds for the negative decision and determines whether the documents must be corrected, a technical issue must be resolved, or the decision of the relevant authority should be challenged.

Registration of Ownership Rights After Commissioning

Commissioning of a property and state registration of ownership rights are connected but separate legal stages. After completion of the construction procedure, it is necessary to check:

• the commissioning document;
• the property address;
• technical characteristics;
• land documents;
• other documents required for registration.

Only after state registration of the property right is completed are the relevant details about the owner and the property entered into the State Register of Property Rights.

Stages of Cooperation with a Lawyer

1. Initial request. You provide the land and construction documents.
2. Legal audit. We review the legal basis for construction, consequence class, and actual condition of the property.
3. Determination of the procedure. Declaration, certificate, or another special procedure.
4. Technical preparation. If necessary, technical inventory and a technical passport are arranged.
5. Document preparation. The package for commissioning is prepared.
6. Submission. Documents are submitted through the relevant system or authority.
7. Resolution of comments. If issues arise, the appropriate method for correcting or challenging them is determined.
8. Registration of rights. After completion of the procedure, state registration of the property is supported.

Cost of Commissioning a Construction Project

The cost depends on the specific property and the required scope of work. The price is affected by:

• the type of real estate;
• the consequence class;
• the area of the property;
• availability of a complete set of construction documents;
• the need for technical inventory;
• the existence of deviations from the design;
• the need to amend documents;
• the need to obtain a certificate;
• subsequent assignment of an address and registration of ownership rights;
• the scope of legal support.

For a declaration concerning a property constructed on the basis of a construction passport, Diia currently indicates that the administrative service is free of charge; for CC2/CC3 certificates, a separate procedure and fee apply in accordance with the current rules.

Common Situations When Commissioning a Property

Conclusion

Commissioning of a construction project depends on how and on the basis of which documents it was built, which consequence class applies, and whether the actual condition corresponds to the construction documentation. A preliminary legal audit makes it possible to identify problems before submitting a declaration or certificate application that could otherwise result in refusal or complicate subsequent registration of ownership rights.
