If you’re buying or selling an older home in Nova Scotia, there’s a good chance you’ll hear the term egress window during a home inspection. This can be surprising and confusing for both buyers and sellers. A home inspector may note that a bedroom window does not meet current egress standards, leaving buyers wondering if the home is unsafe or if expensive upgrades are immediately required.
In reality, it’s not always that simple. The answer often depends on the age of the home, the type of window, other exits and the specific situation.
As a Halifax-Dartmouth REALTOR®, I’ve seen egress windows become a topic of discussion in many real estate transactions. Understanding the difference between current building standards and older construction can help buyers and sellers navigate inspections with greater confidence.
What Is an Egress Window?
An egress window is a window designed to provide an emergency escape route and allow emergency personnel access if needed.
Current building codes include specific requirements regarding window opening size and operation, particularly in bedrooms where occupants may need a secondary means of escape during an emergency.
What Size Does an Egress Window Need to Be?
Current Canadian building standards generally require a bedroom window used for emergency escape to provide:
- A minimum unobstructed opening area of 0.35 square metres (3.77 square feet or 542 square inches)
- No dimension less than 380 mm (15 inches)
- The window must be able to open fully from the inside without the use of tools or special knowledge
It’s important to understand that the actual opening size is what matters, not the overall size of the window frame or glass.
For example, two windows may appear similar in size, but one may provide a much larger escape opening than the other depending on how it operates.
Building codes and standards can change over time, so homeowners and buyers should consult qualified professionals regarding specific situations and current requirements.
Why Does This Come Up So Often in Older Nova Scotia Homes?
Nova Scotia has a large inventory of older homes. Many were built long before today’s building standards existed, and even homes with replacement windows may have had those windows installed before current egress requirements were adopted.
As a result, it is common for home inspectors to note that some bedroom windows may not meet today’s standards.
This does not necessarily mean there is a defect. Rather, it often reflects the difference between modern construction standards and homes built in an earlier era.
Do Older Homes Need to Meet Current Egress Standards?
This is one of the most common questions buyers ask.
In general, building code requirements are not typically retroactive. A home that complied with the standards in place when it was built is not automatically required to be upgraded simply because building standards have changed over time.
That said, buyers should always understand the features and limitations of the home they are purchasing, particularly if renovations, additional bedrooms, or future improvements are being considered.
Basement Bedrooms Often Receive the Most Attention
Egress discussions frequently focus on basement bedrooms because they may have fewer options for emergency escape.
However, egress considerations are not limited to basements. Above-grade bedrooms may also be discussed depending on the age of the home, window style, and window opening dimensions.
Not All Windows Are Equal
One common misconception is that a large-looking window automatically provides a large emergency exit opening.
In reality, the usable opening can vary significantly depending on the type of window.
For example:
- Some sliding windows may provide a smaller opening than many people expect.
- Casement (crank-out) windows often provide a larger usable opening.
- Window operation can be just as important as overall glass size.
This is why measurements and functionality are important when evaluating potential egress concerns.
What Buyers Should Know
If an egress concern is noted during a home inspection:
- Ask questions and seek clarification.
- Understand the age of the home and windows.
- Consider the intended use of the room.
- Recognize that current standards and older construction are not always the same thing.
- Consult qualified professionals if additional information is needed.
A notation in an inspection report does not automatically mean a home is unsafe or that immediate replacement is required.
What Sellers Should Know
Many sellers are surprised when egress windows are mentioned during an inspection, especially if they have owned and enjoyed the home for many years without issue.
In many cases, the discussion relates to current standards rather than a newly discovered problem. Providing buyers with accurate information and understanding the context of the home’s age can often help keep conversations productive and focused on facts.
