is there any scale for "normal wear and tear" on a commercial lease?

The 501 c(3) I work for is moving out of a rental property afer being there for 8 years. The landlord is attempting to charge us for new carpets, repainting, and other miscellaneous repairs. They are fees that are higher than would be expected for these kinds of improvements, and we are wondering if it is normal to have to replace them based on "normal wear and tear" as mentioned in the contract. - Is this your question? Add additional information
