Factory Built Modular Homes

Products are labelled and marked in a permanent manner where it is readily visible after installation with the following information:
1. The QAI label (item 1067, black with gold, 3-1/2” diameter) is normally located in close proximity to the electrical panel and includes:
− Certification label serial number
− QAI certification logo with the “C” Identifier
− “Modular Homes”

2. The specification nameplate (item 1068, 8-1/2” x 14” in size) is normally located in close proximity to the electrical panel and includes:
− Manufacturer’s Name and Address
− Date of Manufacture
− Model Serial Number or Product Code
− Foundation Type (Perimeter Foundation Wall or Piers)
− Floor live Load
− Specified Snow Load (1/50)
− Seismic Response Sa (0.2)
− Hourly Wind Pressure (1/50)
− Envelope Effective Thermal Resistance
− Windows/Doors/Skylights Thermal Characteristics
− Outside Design Temperature (Heal Loss or Heat Gain)
− Factory Installed Appliances
− Site Installed Components, Assemblies, and Systems
− Electrical Systems Voltage, Frequency, and Amperage

3. Other Markings as required by the relevant codes.

Note 3: The QAI label and specification nameplate are available from QAI and must be applied at the factory.

Factory-built modular homes classified under one major occupancy (Group C – Residential), constructed in single or multiple modules, up to 3-storey configuration, with a building area not exceeding 600m². Structures under this scope are constructed within the limitations of Part 9 of the applicable building code.

Buildings described above typically include units used as single-family dwellings, dormitories, boarding and lodging houses, and/or similar structures providing accommodation for sleeping quarters. This listing does not include multi-family residential buildings requiring fire and sound separation or shared egress facilities, such as apartments, duplexes, row houses, townhouses, hotels and motels.

For a full list of structures covered under the above Occupancy Classifications, please refer to Division B, Notes to Part 3, A-3.1.2.1.(1) Major Occupancy Classification in the NBC and QCC-B.

Structural:
Conventional Wood Frame Construction within the limitations of Part 9 of NBC and QCC-B. Structures may be built over structural steel support frame.

Electrical Ratings:
120/240 V, 60Hz, 225A max.

Heating/Ventilation:
Primarily Hydronic Heating. Modules may be equipped with electrical baseboard heaters.

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

Gas or Sprinkler Systems:
None.

Fire Alarm Systems:
Fire alarm system consists of smoke detectors, exit signs and emergency lighting.

Notes:
Structures included in this listing are manufactured at a central facility and transported to the site. These modules include provisions for on-site interconnections, connection to municipal services water and sewage, and electrical power supply. QAI certification covers the construction of the structures including any factory installed plumbing and electrical services, 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.
