Hey Mikaela, I am sorry you have to go through this. I am very familiar with Idaho landlord/tenant law (I am not a lawyer and not giving legal advice). It is common in Idaho leases to have the tenant pay for carpet cleaning as part of the lease. If the tenants don't pay for it and leave a receipt, the lease often states that it will be taken out of the deposit. As to the toilet seat and air filter, that really is normal wear and tear unless you have severely damaged the seat. Cleaning the apartment may be taken out of the deposit as well. I don't appreciate having to clean my tenants frig or stove. My leases state exactly what I will charge them if they don't clean up. When you turn in the keys, the apartment is surrendered to the Landlord and you don't have the right to enter without permission. I recommend you video the apartment after you are done cleaning and have all your stuff moved out.
If you feel that you are not getting the correct amount of deposit back, you can take her to court. The landlord has 21 days to send you a itemized damage list and the remaining deposit. Some leases can extend the 21 days to 30 days but Idaho will not permit beyond 30 days. Idaho is fairly Landlord friendly. If you want to take her to court, you will need to show how the place looked when you moved in. Show pictures of the extra stuff in the basement and how the place was cleaned when you moved in. Then you can show the judge how it looked when you moved out. Compare the stuff left and the cleanliness of the apartment. Unless stated in the lease, landlords cannot charge for their time to clean and repair the apartment. They can if they hire someone to do it though. If your landlord has not sent you an explanation within the 30 days, you will have some leverage to take her to court and the judge may be more sympathetic.
You can find the owners/landlords name by checking with the county assessors office or county clerk. It is public information to see who owns the property and their address. You may need to go down to the county clerks office to look it up. Alot of Idaho's systems are not online. Hope this helps.
