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

Multi-residential buildings are designed and constructed within the limitations of Part 9 with vertical fire and sound separations. This certification applies to the construction of detached, semi-detached and row houses have no shared egress facilities, dwelling unit above or below them, shared service space such as attics, crawl spaces, service shafts or service rooms.

This listing does not include multi-residential buildings requiring horizontal fire and sound separation, apartment buildings, hotels and motels, and/or any buildings designed with multiple major occupancies.

For a full list of structures covered under this occupancy please refer to Notes to Part 3, A-3.1.2.1.(1) Major Occupancy Classification in the Ontario Building Code and National Building Code.

Structural:
Conventional Wood Frame Construction within the limitations of Part 9 of the Ontario Building Code and National Building Code.

Electrical Ratings: 120/240V, 60Hz, 200A Max.

Heating/Ventilation: Electric Baseboard Heaters. Modules may be equipped with central forced-air furnace and air conditioning.

Plumbing: Conventional drainage and venting systems to a maximum of 240 hydraulic fixture units.

Gas Systems: None

Notes: Modular Homes 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 homes 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.
