What Is Egress — and Why Does Your Basement Need It?

If you’re finishing or remodeling your basement, you’ve probably come across the term “egress.”  But what exactly is it, and why does it matter?

In short: egress is a way to get out of the basement in an emergency. It’s not just a good idea — in most cases, it’s required by building codes if you’re turning your basement into livable space.

What Is an Egress Window?

An egress window is a window that is large enough and accessible enough for a person to climb out in case of an emergency, like a fire. It also allows first responders to enter the basement if needed.

If you’re adding a bedroom or living area to your basement, building codes typically require at least one egress window or exterior door that meets specific size and accessibility standards.

Egress Requirements: The Basics

While exact requirements can vary slightly by jurisdiction, most codes (including the International Residential Code) include the following rules for basement egress:

✅ Minimum Opening Size

• The window must have a net clear opening of at least 5.7 square feet

• Minimum opening height: 24 inches

• Minimum opening width: 20 inches

✅ Maximum Height from Floor

• The bottom of the window opening can be no more than 44 inches from the floor.

✅ Window Wells (if below grade)

• If the window opens into a window well, the well must:

  
  

  • Provide at least 9 square feet of floor space

  • Be at least 36 inches long and wide

  • Include a permanent ladder or steps if deeper than 44 inches

✅ Easy Operation

• Egress windows must be operable from the inside without tools, keys, or special knowledge. You should be able to open and escape quickly in an emergency.

Why Is Egress So Important?

Besides meeting code, an egress window is an essential safety feature that:

• Provides a safe exit route in the event of a fire or gas leak.

• Brings in natural light and ventilation, making the basement feel more like a true living space.

• Adds value to your home. A basement bedroom without proper egress can’t be legally called a bedroom — and that can hurt resale.

Does Every Basement Room Need Egress?

Not necessarily. Only rooms used for sleeping (like bedrooms) must have their own egress. However, many homeowners choose to add egress windows in common basement living areas for peace of mind and added functionality.

Can You Add Egress to an Existing Basement?

Yes — and we do it all the time.

Adding an egress window involves:

• Cutting through your foundation wall

• Excavating outside the home to install the window well

• Installing a window that meets all size and code requirements

• Waterproofing and finishing the area

It’s a specialized project that’s best left to an experienced remodeling contractor to ensure proper drainage, structural safety, and code compliance.
