A building cadastral survey (pastato kadastriniai matavimai, also called an inventory — inventorizacija) is the measurement of a house, garden house, outbuilding or other building to establish its area, volume, height, completion percentage and building materials. The land surveyor prepares a cadastral data file (kadastro duomenų byla), which you need to register the building in the Real Property Register (Nekilnojamojo turto registras), complete construction, sell it or mortgage it. Without this file, a new house formally remains unfinished construction.
Which buildings do we survey?
We survey residential, non-residential and auxiliary buildings, including unfinished ones.
- Residential houses: single-apartment and two-apartment houses, apartment blocks.
- Garden houses.
- Outbuildings and auxiliary buildings, garages, saunas, greenhouses.
- Non-residential buildings: retail, warehouse, industrial, office, service and others.
- Unfinished buildings and foundations.
- Extensions and reconstructed parts of buildings.
- Apartments and other premises — see apartment cadastral survey.
When do you need a building cadastral survey?
Whenever a building is new, has changed or is about to be sold or mortgaged with outdated data. Typical cases:
- You have built a new house and want to complete and register it.
- You are registering an unfinished building. An unfinished special or non-special structure (ypatingasis or neypatingasis statinys — for example a residential house) must be registered no later than 3 years after the notice of the start of construction (pranešimas apie statybos pradžią), and its changed cadastral data must be updated at least once every 5 years (Law on Construction (Statybos įstatymas), Article 39). An unfinished simple structure (nesudėtingasis statinys) may be registered, but this is not mandatory.
- You have reconstructed the building, added an extension or otherwise changed its area or volume.
- You are legalising an old unregistered building or outbuilding.
- You are selling or mortgaging a building whose cadastral data are outdated.
- The building has been demolished or physically damaged.
How do the building survey and house completion work?
The survey itself is one step of the house completion process. We prepare the cadastral file and the geodetic surveys; the rest is done together with you.
- Enquiry. You send us the address, the building permit and the project (if you have them).
- Document check. We assess what is missing and give you a price.
- On-site survey. The land surveyor measures the building's area, volume and height and establishes its completion level and materials.
- Cadastral file. We prepare the file and upload it to the "Matininkas" subsystem (posistemė „Matininkas“) of the State Enterprise Centre of Registers (VĮ Registrų centras).
- Geodetic surveys. To complete a house you also need a geodetic control survey of the building (kontrolinė geodezinė nuotrauka) and a geodetic survey of the utility networks (inžinerinių tinklų geodezinė nuotrauka).
- Declaration. The construction completion declaration (statybos užbaigimo deklaracija) is completed in the Infostatyba information system (IS „Infostatyba“); it is signed by the owner-builder (statytojas) and the construction manager or technical supervisor.
- Registration. The Centre of Registers registers the building, usually within 5–10 business days.
More about the whole process: House completion.
How long does a building survey take?
From order to completion it usually takes 6–7 weeks. The cadastral file is ready about 2 weeks after the site visit.
| Stage | Duration |
|---|---|
| Cadastral file after the survey | about 2 weeks |
| From order to completion | usually 6–7 weeks |
| File check by the Centre of Registers | within 5 business days (if errors are found, it starts again) |
| Registration by the Centre of Registers | usually 5–10 business days |
| Whole house completion | from a few weeks to a few months, depending on the documents |

What documents will you need?
For completing a single-apartment house:
- A valid building permit (statybos leidimas).
- The detailed (technical) design (darbo (techninis) projektas).
- The cadastral data file (we prepare it).
- The geodetic control survey.
- The geodetic survey of the utility networks.
- An energy performance certificate (energetinio naudingumo sertifikatas) — issued by an energy performance assessor, valid for 10 years.
- The construction completion declaration.
For a two-apartment house, the written consent of all co-owners is also required. For an outbuilding or a legalisation the list may be shorter — we will tell you once we have seen your situation.
Frequently asked questions
How much does house completion cost?
The expert service (house completion via an expert) costs from €600. The geodetic control survey, the building cadastral file and the as-built survey of the utility networks are charged separately.
What is a building inventory?
It is the same as a building cadastral survey: the building is measured and a cadastral data file is prepared.
Does an outbuilding or a sauna need to be surveyed?
If the building is registered in the Real Property Register, it needs a cadastral survey. We check whether your building must be registered based on its purpose and size — call or email us before ordering.
How long does house completion take?
From a few weeks to a few months. The Centre of Registers usually registers the building within 5–10 business days, but everything depends on whether all the documents are ready.
Can an unfinished house be registered?
Yes, an unfinished building is registered on the basis of a cadastral survey that states its completion percentage. You can estimate the approximate completion percentage with our house completion calculator (in Lithuanian).
What if the house was not built exactly according to the project?
Often the project has to be corrected, or a new document authorising construction obtained, before the declaration can be completed. Consult us before the survey.
Does the file need updating after renovation?
Only if the area, volume, wall layout or structure has changed. Painting, replacing floors or updating plumbing does not require a file update.
Do you survey garden houses?
Yes. A simplified procedure applies to some houses built in garden societies (sodų bendrijos) — we will tell you whether it applies to you.
Who submits the file to the Centre of Registers?
The land surveyor uploads the file electronically to the "Matininkas" subsystem. You do not need to bring a printed file.
