It most often appears when buying an older home, house, extension, outbuilding, garage or alteration for which there are no complete building documents. Not every old or unposted object can receive such a certificate.
It is issued by the competent municipal administration after application and evidence according to the applicable regime. The owner presents facts and documents, but the administration does the certification for the specific construction described.
The buyer must establish whether the building or alteration they see and are paying for has a documented legal status. An outbuilding or terrace may increase the advertised area without forming part of the legally described property.
What the document proves
What can you establish from it?
Each document answers a different question. A single document is rarely enough to prove title, completed construction work and the basis for payment at the same time.
What does it establish?
Determines that the precisely described construction is accepted as tolerable under the specified legal regime and based on the data presented. The object may be only part of the visible development.
What does it not establish?
It is not a building permit, a legalization act or a commissioning certificate. It does not prove ownership, structural safety to date, correct use of all premises or automatic cadastral registration.
What to look for in the document
Which details should you compare?
Check the issuer, number and date, legal basis, year and description of the construction, area, location and owner on file. Compare with sketch/diagram, notarial deed, architectural survey and the actual situation.
What comes before and after?
Evidence of construction time and eligibility is collected prior to issuance. Separate cadastral, real property or technical actions may then be necessary; the certificate does not do them automatically.
Where the document comes from
Finding and checking it
Mesto does not automatically retrieve tolerance certificates from a single national register. The absence of a digital record is not proof of either the absence or presence of status.
Request the document and all relevant files from the seller and confirm with the competent municipality. Checking only in the cadastre is not enough, because the application is not an independent guarantee of construction legality.
When do you need a professional review?
An architect or engineer compares the visible building with the survey and assesses compliance. A lawyer checks that the document covers the subject matter of the transaction and how the residual uncertainty is settled before payment.
Before you continue
Check these details

- 01
Determine exactly which construction or alteration is covered by the certificate.
