Landlords are required to do several things related to providing a safe and healthy atmosphere for people who rent their property, such as provide a working furnace and good plumbing. There are times when it makes good business sense for a landlord to replace the carpet. However, there are no rules mandating if or when a landlord must replace carpet.
Landlords operating at this level must go the extra mile to please tenants. High-end tenants are individuals paying anywhere from $4,000 a month and up. They can afford to rent anywhere they please and they expect the very best, especially when it comes to their living environment. So, with high-end rentals, landlords must replace the carpet before a new tenant moves in and each time the tenant renews the lease. If your high-end tenant has a good record of making payments on time, you would also replace all or a portion of the carpet at any point during the lease period if that's what it takes to keep a smile on their faces.
Class B rentals are usually 10- to 15-year-old buildings in a nice part of town where tenants are likely to be white-collar professionals. At a bare minimum, a landlord of a Class B rental unit should expect to replace the carpet each time a tenant moves out. It would also be a good idea for a landlord to offer to replace the carpet each time the tenant renews the lease.
Low income rentals generate less income for landlords so that is why the carpet in low-income rentals is replaced less often. A landlord might have to sacrifice up to two months' worth of rent to cover the cost of the carpet and installation for an entire house or apartment in a low-income rental. But if the tenant has a solid payment history over a number of years and plans to stay in the house or apartment for the foreseeable future, it might be well worth a landlord's investment to replace the carpet.
Typically, in most rental agreements, the carpet is the tenant's responsibility to keep clean while they live in the rental unit and before they move out. If a tenant has lived in the house or apartment for four or five years and requests new carpet that will cost more than a month's rent, it's not unreasonable to ask the tenant to split the cost of the carpet. It's a win-win situation where the tenant gets new carpet and the landlord gets a slight increase in property value.
