In St. Martins, Puerto Rico, buildings are inspected by independent, third-party inspectors. This leads to a higher level of confidence in inspectors' decisions. Researchers reviewed the permit files of the 14 participating cities, and chose small and large homebuilders. Constructors and inspectors are looking for precise descriptions and codes. It is also important for homebuilders to understand the intention of the codes and the reasons for them.
All municipalities have some kind of codes, which are often very similar.
