Egress windows serve a critical role in ensuring the safety of occupants by providing a means of emergency exit from living spaces, especially in basements. In Michigan, like in many other states, specific building codes and regulations govern the installation and requirements of egress windows for safety and compliance. Let’s delve into the egress window code details relevant to emergency exits in Michigan.

What Is an Egress Window?

An egress window is a window designed to provide a safe and accessible exit from a building in case of an emergency,

Key Egress Window Code Requirements in Michigan

Minimum Size Requirements:

Egress windows must have a minimum clear opening width of 20 inches, a minimum clear opening height of 24 inches, and a minimum clear opening area of 5.7 square feet. The maximum height from the floor to the bottom of the clear opening should not exceed 44 inches.

Window Well Requirements:

If the egress window is located below grade and the window well depth exceeds 44 inches, a permanently affixed ladder or steps are required. The ladder or steps must be a minimum of 12 inches wide and project a minimum of 3 inches from the wall but no more than 6 inches.

Location and Accessibility:

Egress windows should be easily accessible and operable without the use of keys or tools. They should not be located in bathrooms, closets, or similar spaces where privacy is expected.

Grade-Level Windows:

For windows at grade level (for example, in a basement), window wells should be provided if the window’s sill height is below the adjacent ground elevation.

Emergency Escape and Rescue Openings:

Basement sleeping rooms are required to have at least one emergency escape and rescue opening. Additionally, other habitable rooms used for sleeping or living purposes require emergency escape openings.

Installation and Compliance

It’s crucial to consult with a licensed contractor or building professional to ensure compliance with the specific egress window code requirements in Michigan. Professionals have the expertise to accurately determine the size, location, and other factors to ensure the installation meets code specifications.

Permitting and Inspections

Before installing an egress window for Emergency Exit Michigan, a building permit is typically required. Local building authorities will inspect the installation to ensure it complies with the relevant codes and regulations.

Conclusion

Compliance with egress window codes in Michigan is essential for the safety of the occupants of a building, particularly in basement living spaces. By following the specific requirements outlined in the building code, you can ensure that your egress windows meet safety standards and provide a reliable means of emergency escape in the event of a fire or other emergencies. Always consult with professionals and obtain necessary permits to ensure compliance with Michigan’s egress window code.
