Everything You Need to Know About Below Grade Entrance Drawings and Permits

Are you planning to add a separate entrance to your basement? Whether you’re creating a legal basement apartment or simply improving access, a below grade entrance is a smart investment. But before the shovel hits the ground, there’s one essential step you can’t afford to skip: getting a permit with accurate drawings.

What Is a Below Grade Entrance?

A below grade entrance is an entryway installed below ground level, typically leading directly into the basement. It’s common in homes where homeowners want to create legal secondary units, accessory dwelling units (ADUs), or simply increase the functionality of their space.

These entrances often include:

  • Concrete stairs
  • Retaining walls
  • Drainage systems (like sump pits or trench drains)
  • Structural changes to existing foundations

Because of the significant changes involved, these projects are highly regulated by local building codes.

Why Do You Need a Permit?

In cities across Ontario, including Toronto, Mississauga, Brampton, and Hamilton, a permit is required before building a below grade entrance. The city needs to review your plans to ensure:

  • The design is safe and structurally sound
  • Proper drainage is in place to prevent flooding
  • The new entrance meets zoning bylaws and setback requirements
  • You’re not negatively affecting neighboring properties

Failing to get a permit can lead to stop work orders, fines, or issues when selling or renting your property.

The Role of Drawings in the Permit Process

To apply for a below grade entrance permit, you’ll need professional architectural drawings. These include:

  • Site plan showing property layout
  • Foundation wall modification details
  • Stair and guard design
  • Drainage and grading plan
  • Cross sections and elevations

These drawings must be prepared by a qualified designer or licensed engineer, depending on your municipality’s requirements.
