Normal wear and tear is that amount of physical depreciation that a leased premise can reasonably be expected to suffer, when used for the purposes that it was leased, by a reasonably prudent tenant. Of course, as with all issues, what is reasonable to one person may not be reasonable to another, including the judge. Nothing lasts forever. Consequently, courts reasonably expect that carpets will wear out (approximately every seven years), major appliances will cease functioning (approximately every twelve years), and that premises will need to be repainted (approximately every five years).
