Radon Rules When Building a Home on Vancouver Island

Building a Home on Vancouver Island? Don't Forget About Radon

When planning a custom home on Vancouver Island, most homeowners think about foundations, insulation, drainage, heating, and energy efficiency.

One thing that gets far less attention is radon.

Radon is a naturally occurring radioactive gas that can enter buildings from the ground.

Because of this, the BC Building Code includes requirements intended to address soil gas and radon in new construction.

How Does Radon Get Into a Home?

Radon originates naturally in the ground.

It can potentially enter a building through openings and penetrations in areas that separate the home from the soil.

That makes the foundation and below-grade construction important parts of radon protection.

How Can This Affect a New Home?

Depending on the applicable building-code requirements and home design, radon and soil-gas measures can affect details involving:

• Foundation construction

• Concrete slabs

• Sealing around penetrations

• Soil-gas barriers

• Sub-slab preparation

• Radon rough-in systems

These details are much easier to address while the home is being built than after the basement or slab has been completed.

Why Should Vancouver Island Homeowners Care?

Radon levels can vary significantly from one property to another.

You shouldn't assume your property has the same conditions as another home nearby.

For someone building a custom home, the important point is simple:

Think about radon during construction, not after construction.

The builder and design team can determine which current BC Building Code requirements apply to the project and incorporate them into the foundation and mechanical planning.

Another Reason to Understand the Building Site

Radon is a good example of how conditions homeowners can't see can influence a custom home.

The same property may require consideration of:

• Geotechnical conditions

• Drainage

• Groundwater

• Radon and soil gases

• Environmental requirements

• Energy requirements

• Foundation design

Understanding these items early helps the home design respond to the actual property.

At Howson Homes, our custom-home planning process starts with understanding the site before construction begins.
