Understanding Egress Window Requirements in Wisconsin
An egress window is not just any basement window. It is a designated emergency exit that must meet strict dimensional and operational criteria set by the Wisconsin Uniform Dwelling Code (UDC) and the International Residential Code (IRC). 1 These codes are designed to ensure that occupants, including emergency responders, can quickly and easily exit or enter a bedroom in the event of a fire or other crisis. In West Allis, these rules are enforced through the local building permit process, making compliance non-negotiable for creating a legal basement bedroom. 2
The core purpose of these emergency egress openings is life safety. A standard basement hopper window is insufficient for escape or rescue. The specific requirements for clear opening size, sill height, and ease of operation are all calculated based on the average size of a firefighter wearing full gear. 3 When you invest in a proper egress window installation, you're not just adding light; you're adding a critical layer of protection for your family and increasing the lawful, usable square footage of your home.
West Allis Code Specifications for Egress Openings
For any basement bedroom in West Allis, the egress window must satisfy several precise measurements. It's important to note that the "clear opening" refers to the space available when the window is fully open, unobstructed by the window frame or sash.
- Minimum Size: The net clear opening must be at least 20 inches wide by 24 inches high. 1 4
- Minimum Area: The total clear opening area must be a minimum of 5.7 square feet (5.0 square feet for ground-floor bedrooms). 1 5
- Maximum Sill Height: The bottom of the clear opening cannot be more than 44 inches above the finished floor of the room. 1 6
- Operation: The window must be operable from the inside without the use of keys, tools, or special knowledge. It should open with normal force. 7
Failing to meet any one of these specifications means the window does not qualify as a legal egress, and the room cannot be considered a bedroom. This has implications for both safety and home value.
The Crucial Role of Window Wells
Since basement windows are typically below ground level, an egress window well is an essential companion to any below-grade escape window. The well creates the accessible space outside the window needed for a person to climb out. Wisconsin and West Allis codes have specific rules for these wells: 8 7
- Minimum Well Size: The horizontal area of the well must be at least 9 square feet, with a minimum dimension of 36 inches in width and depth (36"x36"). 6
- Accessibility: The well must provide unobstructed access to the window.
- Drainage: Proper drainage is required to prevent water from accumulating in the well, which could lead to basement flooding or ice hazards.
- Ladders or Steps: If the depth of the window well exceeds 44 inches, the code mandates the installation of permanent ladders or steps to facilitate escape. 1 3
A professional installer will ensure the well is correctly sized, drained, and equipped to complement the egress window, creating a fully functional emergency exit system.
The West Allis Permit Process for Egress Windows
Installing or replacing an egress window in West Allis always requires a building permit. 2 9 This process is in place to verify that the planned work meets all structural and safety codes. Skipping the permit can result in fines, forced removal of the work, and problems when you sell your home.
The typical steps are:
- Determine Need: Confirm with the City of West Allis that your project requires a permit. Adding or enlarging a window in a foundation wall always does. 2 10
- Apply for Permit: Submit a complete building permit application, including detailed plans of the proposed window and well, to the City of West Allis. This can often be started online. 9
- Plan Review: City building officials will review your submitted plans to ensure the proposed size, location, and structural details comply with the Wisconsin UDC.
- Installation: Once the permit is issued, the egress window and well can be installed according to the approved plans by a licensed contractor.
- Final Inspection: After installation, a city inspector must visit the site to verify that the finished work matches the plans and meets all code requirements. 11 This final inspection is crucial for closing out the permit.

Cost Considerations for Installation and Replacement
The total cost of an egress window project in West Allis can vary widely based on several factors. It's more than just the price of the window unit itself. Key cost drivers include:
- Permit Fees: The City of West Allis charges a permit fee, which can range from approximately $50 to $500 or more, depending on the project's valuation and complexity. 9 12
- Window & Well Materials: Costs differ based on the type of window (e.g., casement, sliding), the material (vinyl, fiberglass, wood), and the well material (metal, polymer, masonry).
- Labor and Structural Work: This is often the most significant variable. If your foundation wall needs to be cut (which is common for new installations), costs increase due to the need for sawing, structural support (like lintels), and masonry repair. Labor costs can range from a few hundred to several thousand dollars. 1 7
- Engineering: Some projects, especially those involving complex structural modifications, may require a stamped engineering report, adding to the cost. 9
While it's a significant investment, a properly installed egress window can add substantial value to your home by creating a legal bedroom and improving safety and livability. 8
Egress Windows for Bedrooms vs. Recreational Rooms
It's important to distinguish between rooms that require an egress window and those that do not.
- Basement Bedroom: If you intend to label and use a basement room as a bedroom, a code-compliant egress window is mandatory. 2 11 This is a non-negotiable safety requirement for obtaining an occupancy permit for the bedroom.
- Basement Recreation Room: For a general-purpose rec room, family room, or home theater, an egress window is not required by code. However, you may still choose to install one for natural light, ventilation, and peace of mind. Any new window installation in a foundation wall will still require a permit. 2
Choosing the Right Professional for the Job
Given the structural and regulatory complexities, selecting an experienced contractor is paramount. Look for professionals who:
- Are familiar with West Allis and Wisconsin egress window codes.
- Have a proven track record of obtaining local permits and passing inspections.
- Can explain the entire process, including well drainage and ladder requirements.
- Provide clear, detailed estimates that break down material, labor, and permit costs.
- Are licensed and insured for residential structural work.
A qualified installer will handle the permit paperwork, ensure the structural integrity of your foundation, and deliver a finished product that keeps your home safe and compliant for years to come.
