In a nutshell here is how it works: Modular buildings must adhere to the National Building Code (NBC) and local building codes – the same as site-built structures. The NBC allows off-site reviews for factory-built components. The certification of the factory process to the CSA A277 standard procedure ensures off-site compliance and eliminates the need for re-inspection of factory-built components. Site work (e.g., foundations, connections) still requires local inspections.

Flooding in homes is a significant concern: 20% of Canadian homes are at risk due to one or more of these failures: • Sewer backup: Sewer systems become overwhelmed; sewage backs up into homes • Infiltration flooding: Surface water seeps into basements through cracks in the foundation • Overland flooding: Rainwater accumulates around houses due to poor grading or drainage

Accessibility and Visit-ability

The Canadian Home Builders’ Association (CHBA) supports the participation of all individuals in society. CHBA recognizes that society does not always accommodate every individual’s needs, and that this can limit their participation in society. CHBA supports accessibility and visit-ability as it applies to facilities and services open or provided to the public. Conversely, CHBA recognizes that Canadians view their homes as a private space—a space they expect to tailor to their individual needs,

Making standards work for builders and renovators

The residential construction industry is a critical driver of Canada’s economy, and a key source of employment. Canada is also facing a housing affordability crisis, making it critical that all codes and standards development ensures affordability is a key consideration. Indeed, CHBA recommends that proving there will be no negative impact on affordability must be a mandatory approval step in the development of all codes and standards related to residential construction.

Overheating

What is the peak cooling load? The peak cooling load is the predicted rate of heat removal required at the height of summer to maintain a comfortable temperature in a building. The peak cooling load is also used to size cooling equipment.
