Who Should Design Plans?

It is required that all buildings be designed to Jamaica Building Code standards. Buildings greater than 300m² must be designed and stamped by registered professionals (architects/Engineers). Buildings less than 300m²  can be designed by other skilled professionals (Draughtsman). However, buildings that are considered to be complex structures and or requiring complex services whether < or > 300m² should be designed by registered professionals.
