The only time a landlord must replace the carpet is if it somehow affects the health or safety of the tenants, such as if the carpet is moldy, unsanitary or ripped. The law does not govern aesthetics, so even if the carpet is stained or old, as long as it is in fair condition, the landlord does not have to replace it.
There are several factors that can effect how long your carpet lasts, whether it's where you live, who you live with, or what you do in your home. But even carpet under the most trying of conditions can last many years, with the right carpet maintenance. In the average household of about 2-4 residents, carpet lifespan is usually about 3-5 years. It is by this point that most carpet fibers become old and frayed. Stains will also have sunk in, turning what started out as a pure white carpet into something graying and dull.
