Relocatable Structures included in this listing are manufactured at a central facility and transported to the site. These modules must include provisions for on site interconnections, connection to municipal services (water and sewage), electrical power and gas/propane supply. QAI certification covers the construction of the modular buildings including any factory installed plumbing, electrical and gas/propane services, appliances, equipment and fixtures. QAI certification is intended to obviate the necessity of further inspection by the local regulatory authorities except for site connections to services or to other modules and for site installed features.
Site installation of products must be done according to manufacturer’s installation instructions and in compliance with the requirements set by the local authority having jurisdiction.
