An apartment cadastral survey (buto kadastriniai matavimai) is the measurement of an apartment, in which a land surveyor establishes the area of every room and auxiliary space and prepares the official apartment floor plan. These data are entered in the cadastral data file (kadastro duomenų byla) and registered in the Real Property Register (Nekilnojamojo turto registras). You need one after a layout change, when the apartment data are outdated or missing, and when registering a new apartment.
An official floor plan and a furniture layout plan are not the same
You can draw an apartment plan online for free, for example with apps such as "Planner 5D" or "Floorplanner". Such a plan is fine for renovation and arranging furniture, but the State Enterprise Centre of Registers (VĮ Registrų centras) does not accept it.
The official apartment floor plan is part of the cadastral data file. Only a qualified land surveyor can prepare it, and its data have legal force. This is the plan you need for transactions, for the bank and for legalising a layout change. More in the article "Apartment floor plan: what it is and where to get it" (in Lithuanian).
When do you need an apartment cadastral survey?
- You have changed the layout: merged rooms, moved walls or changed how the rooms are arranged.
- You have glazed the balcony or otherwise changed the apartment area.
- You are selling or inheriting an apartment whose cadastral data are missing or outdated.
- You are mortgaging the apartment, and the bank needs up-to-date register data.
- You are registering a new apartment in a new building.
- The apartment area in the documents does not match the real area.
If the apartment has a valid cadastral data file and nothing in it has changed, it does not need to be surveyed again just because you are selling it.
How does an apartment survey work?
- Enquiry. You send us the apartment address and unique number (unikalus numeris) and tell us what has changed.
- Check. We review the register data and tell you whether a survey is really needed and whether permits will be required to legalise a layout change.
- On-site survey. The land surveyor visits and measures all the rooms.
- Cadastral file. We prepare the file with the official apartment floor plan. The floor plans of the building storey are often updated at the same time.
- Submission. We upload the file electronically to the Centre of Registers' "Matininkas" subsystem (posistemė „Matininkas“) — you do not need to bring anything.
- Registration. You submit an application to the Centre of Registers to change the apartment data. The Centre of Registers checks the file within 5 business days.
How long does it take?
| Stage | Duration |
|---|---|
| Preparing the file | about 2 weeks after the survey |
| From order to completion | usually about 4 weeks |
| File check by the Centre of Registers | within 5 business days (if errors are found, it starts again) |
| Registration | usually 5–10 business days |

What documents will you need?
- An ownership document or an extract from the Real Property Register (Registrų centro išrašas).
- The existing cadastral file or floor plan of the apartment (if you have one).
- After a layout change, reconstruction or repair — documents confirming that the construction work was lawful (Real Property Cadastre Regulations (Nekilnojamojo turto kadastro nuostatai), point 84¹.2).
- After a simple repair — the construction completion declaration (statybos užbaigimo deklaracija); after a reconstruction or major repair — a declaration approved by an expertise contractor.
Frequently asked questions
Does an apartment need to be surveyed before a sale?
No, if the apartment has a valid cadastral file and nothing in it has changed. If the data are missing or outdated, or the layout has been changed — yes.
How do I get an official apartment floor plan?
The official apartment floor plan is part of the cadastral file. It is prepared by a land surveyor, and the data are registered with the Centre of Registers.
Can I draw the apartment plan for the Centre of Registers myself?
No. A plan you draw yourself is only suitable for renovation and arranging furniture. The Centre of Registers accepts only a file prepared by a land surveyor.
I merged the kitchen with a room. Do I need a new survey?
Yes, if the room layout or areas have changed. You may also need documents confirming that the work was carried out lawfully.
Does an apartment need to be surveyed after renovation?
Only if the areas, wall layout or structure have changed. Replacing floors, painting or updating plumbing does not require a survey.
How much does an apartment cadastral survey cost?
A cadastral survey of an apartment or premises up to 200 m² costs €240 including VAT; larger ones about €1.21/m². The price may differ if a layout change needs to be legalised. We give an exact price once we have seen the apartment data.
Does a glazed balcony change the apartment area?
After a balcony is glazed, the apartment's cadastral file often needs to be updated. We will tell you whether this is needed in your case.
Can the bank require a new survey?
Yes. When an apartment is mortgaged, up-to-date Real Property Register data are needed. If they are outdated, the transaction may be put on hold.
Do I need to be at home during the survey?
The owner or a person authorised by the owner needs to let the land surveyor into the apartment.
