Mechanical Checklist required for Single Family Dwellings

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 to much air with a high cfm fan can cause depressurization in the house and an additional makeup air system would need to be installed.

Plumbing Permits

We now have a separate application for plumbing permits that is required for new or repaired plumbing fixtures 

Proof of Potable Water

Required for any construction project that have not had existing plumbing.

Proof of Liability Insurance

If a registered professional is required for the construction project, a proof of liability 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 structrual damage to foundations and superstructures.

The BC Building Code states: Protection from Freezing
1) The bottom of excavations shall be kept from freezing throughtout the entire construction period.
It is the homeowner and contractors responsibiity to ensure that an appropriate amount of heat is supplied to the excavation.
