Q: My elderly mother has lived in a rental townhome in Fairmont, Minn., for 17 years. Amazingly, the carpet is in very good condition as it's Berber and very tough. The lease states they will deduct $155 for carpet cleaning. Isn't a carpet fully depreciated by that length of time? Therefore, isn't it unethical for them to charge to clean the carpet? I feel like the company will charge the cleaning fee, then change the carpet for a new tenant anyway. Also, she purchased blinds for the picture window and all the other windows. What happens there?

A: Landlords in Minnesota must return all or part of the security deposit within 21 days, withholding only amounts reasonably necessary to cover past rent or other money owed to the landlord, or to restore the rental to its condition at the start of the lease excluding ordinary wear and tear.

If the landlord is keeping all or part of the security deposit, they must include a letter with an itemized list of damages and replacement costs. Landlords may not charge nonrefundable deposits such as an automatic carpet cleaning charge with an automatic deduction taken from the security deposit once the tenant moves out.

However, it is acceptable to charge a carpet cleaning fee or administrative fee if the tenant is told about it, such as in their lease and in any advertising. It is considered a good practice for landlords to let tenants know potential cleaning charges upfront, and since the carpet cleaning fee was written into your mother's lease, then she was made aware of it.

Berber carpet does hold up well over time, and since you stated the carpet was in "very good condition" the landlord may not be replacing the carpet, but just cleaning it for the next tenant. After 17 years the carpet would most likely be fully depreciated, so they shouldn't be charging your mother to replace the carpet. However, if they do clean the carpet and incur this fee, then most courts would consider that a valid expense for a landlord to charge against the security deposit.

You and your mother can protest this charge and sue in conciliation court, but I can't predict that you will definitely win. Open communication with your mother's landlord is the best way to proceed. After 17 years there could be a new landlord or maintenance staff that doesn't know your mother purchased her own blinds for the apartment.
