In Russia, the law on apartment redevelopment will change from April 1. Redevelopment will be considered not only a change in the configuration of a room, but also any transformation of its shape and size.
The owner needs to prepare a package of documents and contact the local administration or the State Housing Inspectorate. If the innovation is approved, after the completion of the repair, you need to return to the authority that issued the permit - it will send a selection committee that will record the changes.
