It was stipulated that he should not use electrical appliances in the student residence
Question

                I am a student in a European country, and I rent a room in the student residence in the University. Among the conditions listed in the rental contract, there is a clause which stipulates that I should not use electrical appliances except for those which are provided with the room, in addition to the computer. I have a personal washing machine, and before I was certain about this clause, I was using it, because it is very expensive to use the laundromat here. My question is: is it permissible to use electrical appliances when there is this clause? Please note that there is a real need for these appliances and the people in charge of the residence do not agree to take extra rent in return for allowing us to use these appliances.
Praise be to Allah.
    If it is stipulated in the rental contract that you should 
    not use any electrical appliances except those that are supplied with the 
    accommodation, then you have to adhere to this condition, and it is not 
    permissible for you to use your personal washing machine unless the people 
    in charge agree to that, because the basic principle is that you are obliged 
    to fulfil agreements and adhere to conditions. Allaah says (interpretation 
    of the meaning): “O you who believe! Fulfil (your) obligations” 
    [al-Maa’idah 5:1. And the Prophet (blessings and peace of Allaah be upon 
    him) said: “The Muslims are bound by their obligations.” Narrated by Abu 
    Dawood (3594). Classed as saheeh by al-Albaani in Saheeh Abi Dawood. 

    This condition that you mention is usually stipulated in 
    student residences so as to avoid serious problems. Based on the large 
    numbers of students in the residences, if each of them were allowed to use 
    whatever electrical appliances he wants to, the circuits would not be able 
    to bear this heavy load, which would lead to frequent outages and that would 
    harm the students or cause a fire. 

    This confirms that you have to adhere to this condition. 

    And Allaah knows best.
