The lessee typically agrees not to alter or improve the premises without the lessor's consent except in the case of minor alterations or improvements, such as changing the wallpaper or partitioning the premises.  In addition, many lessors require the lessee to use the lessor's contractor for alterations or improvements even where the lessor consents to such alterations or improvements.  At the end of the lease term, the lessee is obligated to return the premises to the lessor in their original condition at its own expense upon expiration of the lease term.
