Check the FIAS address before a building is commissioned

From 1 February 2026, a technical plan or a boundary plan used to enter new properties on the cadastral register must state not the address as a line of text, but the unique address identifier from the State Address Register and the Federal Information Address System (GAR/FIAS): the FIAS ID.

Why this matters now, for owners and developers "at commissioning"

If the property does not yet have an address in GAR/FIAS at the level of "building / structure / block", an extra step appears in the chain commissioning → technical plan → filing with Rosreestr:

• an address has to be assigned, and one has to wait for the entry to appear in GAR/FIAS, in order to obtain a FIAS ID.

What must be in FIAS

FIAS/GAR stores addresses in a hierarchy (city / district / settlement / street / ... / building / structure / premises). For a new building it is critical that an address with a building, structure or block number appear in the GAR. An identifier (the FIAS ID) then comes into being, and it is that identifier which is entered in the technical plan.

Who may apply for an address to be assigned

The application may be filed by the right-holder and, in the cases provided for, by the cadastral engineer as well.

A checklist for "30 days before filing with Rosreestr"

1. Check the address in FIAS/GAR: whether there is an entry for the property itself, and not only for the street, and whether the identifier is visible.

2. If there is no address, start the assignment of an address in advance, and not on the day of the technical plan.

3. Align the address with the design and with the commissioning documents: block, structure and letter, so that the documents do not contain inconsistent readings.

How to start the assignment of an address in FIAS, taking Moscow as an example

1. we check whether the address is present or absent on the FIAS website (fias.nalog.ru);

2. if there is no address, we file a request for the service "Assignment of an address to an addressable object" on the website of the Government of Moscow (mos.ru).

The time for providing the service is from 5 to 15 working days.

Why the state wants this link

In practice an address is one of the identifiers that shifts the most. For years, different public authorities and systems have lived with their own directories and their own rules for writing an address down: one and the same property can be recorded in a dozen ways. When there are no other reference points, above all a cadastral number, manual reconciliation begins. That is hours of work, and a constant risk of error.

The state has long been moving towards unification through GAR/FIAS and uniform rules of addressing, including in order to identify mass registration of fly-by-night companies. The change of 1 February 2026 is a further step in that direction: instead of an "address as a line of text", cadastral documents use an address identifier (a FIAS ID). The point is simple. Less manual matching means fewer problems, both for right-holders and for public authorities, comments Sergei Pivovarchik, managing partner of Consul Group.
