Egress Window Requirements, Permits and What Buyers and Sellers Should Know

If you are finishing a basement, adding a bedroom or preparing to sell your home in Winnipeg, understanding egress window requirements is essential.

Egress windows are not just a design choice — they are a life safety requirement under building code and City of Winnipeg regulations. Whether you are enlarging an existing window or adding a new one, there are structural, permit and resale implications to consider.

Here is what Winnipeg homeowners need to know.

What Is an Egress Window?

An egress window is a window large enough to allow safe exit in case of an emergency and to allow emergency responders to enter if needed.

In Winnipeg, if a room is labeled or marketed as a bedroom, it must meet egress requirements. Without proper egress, the room does not legally qualify as a bedroom.

City of Winnipeg Egress Window Requirements

To comply with City of Winnipeg requirements for bedrooms,

• The window must have an unobstructed opening of at least 0.35 m² (3.77 sq. ft.)

• No dimension of the opening can be less than 380 mm (15 inches or 1’-3”)

• The window must open fully without obstruction

• Security bars, grilles or screens must be removable without tools

In basement situations, this often means the existing window is too small and must be enlarged.

Egress Windows Are Required for All Bedrooms

Under building code requirements adopted by the City of Winnipeg, every bedroom must have a compliant egress window, regardless of whether the bedroom is located above ground or in a basement. This means that both main floor and upper-floor bedrooms must also meet the minimum clear opening standards, not just basement bedrooms. 

 

Clear Opening Requirement for Egress Windows

One important detail many homeowners overlook is that egress window measurements are based on the clear opening only.

This means the unobstructed space when the window is fully open must meet the minimum size requirement. The measurement does not include any part of the window structure itself.

The following do not count toward the required egress opening size,

• Window frames

• Sashes

• Grilles or decorative bars

• Screens

• Locks or hardware

Only the actual open space a person could climb through is used to determine whether the window meets egress standards.

Egress window requirements are based on the National Building Code of Canada (NBCC), which establishes minimum safety standards for residential construction across the country. While the NBCC provides the national framework, local municipalities adopt and enforce these rules through their own building bylaws and permit systems. In Winnipeg, the City uses the NBCC as the foundation for its building regulations, meaning the egress window requirements for bedrooms align with the national safety standards.

 

Why Egress Windows Matter

1. Life Safety

The primary purpose of an egress window is emergency escape and rescue.

In the event of a fire,

• Basement bedrooms can become trapped spaces

• Stairwells may be inaccessible

• Egress windows provide a secondary exit

They also allow firefighters to enter directly from outside if needed.

2. Legal Bedroom Classification

If a bedroom does not meet egress window requirements,

• It cannot legally be advertised as a bedroom

• Appraisers may not count it as a bedroom

• Buyers may question compliance

• Insurance implications can arise

Above ground bedrooms that do not have an egress window, but have a door that exits to the outside will meet the requirements of being a legal bedroom. 

For resale value, proper egress can significantly impact how your property is marketed.

3. Increased Property Value

Installing compliant egress windows can,

• Increase legal bedroom count

• Improve resale appeal

• Support rental suite development

• Add natural light to bedroom spaces

In Winnipeg’s competitive Real Estate market, legal bedroom count can make a meaningful difference.

Adding or Enlarging an Egress Window in Winnipeg

In many older Winnipeg homes, windows were originally small and do not meet current standards.

To comply, homeowners often must,

• Enlarge the window opening

• Cut into walls or foundation walls

• Install a properly sized window

• Add a window well for basement egress windows

• Ensure proper drainage for basement window wells

Because walls and foundation walls are structural, this work must be handled carefully to the required codes and the work completed by professionals.

Engineered Egress Windows and Permits

When altering walls or foundation walls in Winnipeg,

• A building permit is required

• Engineered drawings are required

• City inspection is required upon completion

Foundation wall cutting must be structurally reinforced according to engineered specifications.

A typical scope of work for a standard egress window may include,

• Excavation at the exterior foundation wall

• Changes to the framing of the house

• Concrete cutting to enlarge opening

• Installation of structural lintel support

• Window installation

• Window well installation

• Drainage connection

• Interior finishing

• City inspection approval

Failing to obtain permits and have a city inspection can create complications during resale.

What Buyers Should Know About Egress Windows

If you are buying a home,

• Confirm that all bedroom windows meet egress standards

• Ask whether permits were obtained if an egress window was recently installed

• Verify inspections were completed if an egress window was recently installed

• Review listing details carefully to ensure the number of legal bedrooms are correct

If a listing says “bedroom” but the window is undersized, that space does not legally qualify.

This can affect,

• Appraisal value

• Financing approval

• Insurance coverage

• Future resale

What Sellers Should Know

If you are selling a home in Winnipeg,

• Ensure all bedrooms are compliant for egress windows

• Avoid marketing non-egress rooms as bedrooms

• Keep documentation of permits and inspections if egress windows are installed

• Consider upgrading windows before listing

Proper compliance increases buyer confidence and protects against transaction delays.

Secondary Suites and Rental Potential

For homeowners considering income-generating properties,

• Legal secondary suites require compliant egress windows

• City approval and inspection are mandatory

• Proper bedroom classification impacts rental legality

Installing engineered egress windows may open opportunities for legal rental income, helping offset mortgage payments and build equity.

Drainage and Safety Considerations

A compliant Manitoba basement window well must have,

• 760 mm (30 in) clearance in front of the window

• window must open fully without obstruction

• ladder if deeper than 1.5 m (5 ft)

• covers must open without tools or keys

• proper drainage to prevent flooding

Improper installation can lead to water infiltration issues, particularly during Winnipeg’s heavy spring thaw.

Minimum clearance in front of the window

The window well must provide at least,

760 mm (30 in) of clear space in front of the window.

This space must allow the window to fully open without obstruction.

Measured from,

• the window frame or sash

• to the inside face of the window well

 Egress Windows Protect People and Property Value

Egress windows are not optional when creating legal bedrooms in Winnipeg — they are a life safety requirement and a building code standard.

Whether you are,

• Finishing a basement

• Adding rental potential

• Buying a home

• Preparing to sell

Understanding City of Winnipeg egress window requirements protects your investment and ensures compliance.

In Winnipeg real estate, legal bedroom count and safety standards matter. Properly installed and permitted egress windows not only provide emergency escape — they support resale value, rental potential and long-term property integrity.
