Register an additional dwelling in the Catastro (physical alteration 901N/902N)
Energy certificates expire. Without a valid one, the contract may be voided.
Use this to tell the Catastro that your property now has an additional dwelling (from works, internal segregation or a change of use). It lets each dwelling get its own referencia catastral and makes sure the IBI is calculated correctly.
