Colorado Real Estate Journal - A Guide to Colorado-specific Laws in Retail Leases Behind every successful retail relationship is a carefully negotiated lease. I am not saying this just because I’m a leasing attorney (OK, maybe partly). A lease agreement inherently guides the operation of a retail space. When negotiating leases, retail landlords and tenants will need to consider various local, state and federal laws, along with applicable market considerations and deal-specific terms. In Colorado, there is not a single set of state laws or regulations that govern commercial leases; a majority of the landlord-tenant statutes apply only to residential leases.
