Single family dwellings classified under one major occupancy (Group C – Residential), constructed in single modules configurations. Modular homes under this scope have a building area not exceeding 600m².

Residential buildings are designed and constructed within the limitations of Part 9 of QCC and OBC without fire and sound separations. This listing does not include multi-residential buildings requiring fire and sound separation or shared egress facilities, such as duplexes, row houses, townhouses, apartment buildings, hotels and motels, and/or any buildings designed with multiple major occupancies.

Notes:
Prefabricated 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) and electrical power supply. QAI certification covers the construction of the modular buildings including any factory installed plumbing and electrical 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.
