Ok this is a
Minor TENANCY 101 
For all tenants regarding the Issue of Repairs in a House and you should study it carefully to know Your
RIGHTS and the Rights of the Landlord:
1. Never rent a House without a Tenancy Agreement unless its just a penny wise pound foolish behaviour on your own part.
2. In every Tenancy agreement, there are what they call
COVENANTS. These Covenants are rules and regulations that have been agreed between the Tenant and Landlord on how the Tenancy should be run through out the Rent Period.
3. In most Tenancy Agreements, there are what they call
COVENANT TO REPAIR. An agreement without this clause should be frowned upon by the tenant unless the law will deem that you have consented to repair everything in the house whether its your fault or not. Make sure you go through it thoroughly before you consent to it.
The purpose of this covenant is to ensure that the property is kept in good condition and to ensure that the value of the property does not depriciate.
BOTH THE LANDLORD AND TENANT have their respective OBLIGATIONS to repair.
For the purpose of determining the obligation to repair, the parts of the building are classified under law to determine which parts a Landlord and a Tenant is obligated to repair.
A.
STRUCTURAL PARTS: E.g Foundation, Roof, Drainages, Walls etc. In short anything that has to do with the structural parts of a building is under th obligation of the landlord to repair compulsorily.
B.
COMMON PARTS: E.g Stair case, lifts etc (These are parts that deal with common places in the house that adjoins the property together for common Use)
C.
INTERIOR: Door, Windows, Cupboards, Sinks etc (These deal with the interior of the house and its your duty to repair them because you use it for your own convience)
So in short, the Landlord repairs the Common and Structural Parts while you the Tenant repairs the Interior parts.
Now if the Landlord has defaulted in repairing his own parts, the remedy open to you in law is to give notice of repair, demand for Specific performance to repair or when you move out seek for damages in respect of refund of the money spent. You must document all these for your claims to be valid.
Now to answer your question Dovent:
1. You didnt state how many years rent you paid whether it was one or 2 years rent. Even more so, if you have stayed 4 months and the landlord gives you a quit notice, a quit notice is only effective for a valid 6 months since i assumed the rent is paid for a year or 2, so therefore you are a yearly tenant. You are not expected to pack out of that house until the expiration of the 6 months quit notice no matter how he threatens you. If you have only spent 4months, the Landlord is entitled to refund your balance of the remaining year since he knowingly breached the agreement for you to spend the whole one year or 2 years to enjoy quiet enjoyment in that place.
So dont be afraid the law is adequately behind you there.
Also in respect of the repairs, as you must have read above, the landlord is to repair the plumbling since it is part of the structural parts of the house except you delibrately busted a pipe due to your own negligence while in use for your own enjoyment. If it was bad before you entered the House, it is the landlords duty to repair it.
In respect of the door handles, it is you that should repair it if it spoils because you might want to upgrade it to a better form of security for your own convience but as per the door itself, the landlord should repair it if it was bad before you moved in. Also in relation to the Kitchen sink, it is you that should repair it since you used it for your own convience.
Remember the exact state of the house before you moved in would be the balance of possiblities in law to determine what you should do and what the landlord should do. If you consented to move into a poorly built house to move in and saw all the defects and did not press for repairs, then the law wont really aid you, so check the facts again and see where you were wrong and where the landlord is wrong too.
Also anything that has to do with Nepa meter is usually a joint effort between the landlord and tenant to replace or repair unless the tenant has more to lose if you have a very stubborn and stingy Landlord.
Cheers!
