The BC Building Code contains requirements for the introduction of fresh air into BC residences and the exhaust of stale, moisture-laden air. These requirements protect your health and the structural integrity of your dwelling unit. Residential dwelling units, such as houses, apartments and secondary suites are required to have a principal ventilation system that exhausts air from bathrooms and kitchens and supplies fresh air to bedrooms and living areas. The principal ventilation system is intended to create a continuous flow of fresh air through the dwelling unit.
The use of the mechanical ventilation checklist verifies that proper design steps have been taken to ensure the mechanical system has been designed to meet the requirements of BC Building Code and to ensure that the system is exchanging the right amount of air to maintain a balanced system. Exhausting too much air with a high CFM fan can cause depressurization in the house and an additional makeup air system would need to be installed.
We now have a separate application for plumbing permits that is required for new or repaired plumbing fixtures
Required for any construction project that has not had existing plumbing.
If a registered professional is required to provide Letters of Assurance for the construction project, a proof of liability certificate must be provided and submitted.
The BC Building Code prohibits an excavation to be allowed to freeze throughout the entire construction period. This is in place in order to limit the probability of ice lens formation beneath foundations, which could lead to the excessive vertical movement of the soil, which could result in excessive stress on foundations that could cause structural damage to foundations and superstructures.
If you have any questions please contact the Regional District Building Inspections.
