I want to do works in my rented flat
Works that change the layout of the home need the landlord's written consent.
With written permission
Without the landlord's written consent you cannot change the layout of the home.
«El arrendatario no podrá realizar sin el consentimiento del arrendador, expresado por escrito, obras que modifiquen la configuración de la vivienda»
If you do them without permission
At the end, the landlord can require you to restore everything or keep the works without compensating you.
«podrá exigir, al concluir el contrato, que el arrendatario reponga las cosas al estado anterior o conservar la modificación efectuada, sin que éste pueda reclamar indemnización alguna.»
