Steep Slope Building Rules on Vancouver Island

Building on a Steep Lot on Vancouver Island? Check the Development Permit Area First

Found the perfect Vancouver Island property with an incredible ocean or mountain view?

Before designing the house, there's something worth checking:

Is the property inside a Development Permit Area?

Many Vancouver Island communities use Development Permit Areas, commonly called DPAs, to address specific conditions such as natural hazards, environmentally sensitive areas, or other development concerns.

For certain properties, this can affect what needs to happen before construction moves forward.

What Is a Development Permit Area?

A Development Permit Area is an area identified by a local government where additional development guidelines or requirements may apply.

The rules aren't identical across Vancouver Island.

Depending on the municipality or regional district and the specific property, a DPA can relate to issues such as:

• Steep slopes

• Erosion

• Flood hazards

• Environmentally sensitive areas

• Riparian areas

• Wildfire considerations

• Form and character

This means two properties that look similar could have very different development requirements.

Why Steep Lots Deserve Extra Attention

Some of Vancouver Island's best views come from steep properties.

Those same slopes can create additional questions around:

• Slope stability

• Excavation

• Foundations

• Retaining walls

• Drainage

• Driveway access

• Building placement

Depending on the applicable DPA and proposed project, professional assessments or additional approvals may be required.

This is one reason we recommend investigating the property before finalizing the house design.

Where Can This Matter?

Development Permit Areas can be relevant throughout Vancouver Island and surrounding islands.

They are particularly worth investigating when looking at challenging properties around Nanaimo, Ladysmith, the Cowichan Valley, Mount Washington, Gabriola Island, and other Gulf Island locations.

The important point is that the requirements are property-specific.

Don't assume that because someone built a particular home next door, you can automatically do the same thing on your lot.

Check Before You Design

Before purchasing or designing for a challenging Vancouver Island property, it can be worth confirming:

• Zoning

• Development Permit Areas

• Building setbacks

• Environmental restrictions

• Geotechnical requirements

• Riparian requirements

• Servicing

• Access

• Other site-specific regulations

Finding these things early can save considerable redesign later.
