Top Egress Window Replacement & Installation in Beaverton, Oregon Ranked
Adding an egress window is one of the most impactful home improvement projects you can undertake in Beaverton. It transforms a dark basement into a safe, legal living space, increases your home's value, and provides a critical emergency escape route. This guide explains the specific codes, costs, and process for egress window installation in Beaverton, helping you understand what's required to find qualified local professionals for the job.
Understanding Egress Window Requirements in Beaverton
An egress window is not just any basement window. It is a specially sized and designed emergency escape and rescue opening that is mandated by building codes for any habitable room below the fourth story, including bedrooms and living spaces in finished basements 1 2. In Beaverton, these regulations are strictly enforced to ensure life safety.
The City of Beaverton adheres to the Oregon Residential Specialty Code (ORSC), which is based on the International Residential Code (IRC) 3 4. For a basement room to be considered a legal bedroom, it must have a compliant egress window or door. While some existing rooms may be "grandfathered" if they were legally permitted in the past, any new bedroom creation or alteration requires full compliance with current codes 5 6.
Key Code Dimensions for Beaverton Homes
Getting the measurements right is non-negotiable. Here are the critical size and operational requirements you must meet:
- Minimum Opening Area: The clear, openable space must be at least 5.7 square feet 3 7. For windows below grade (ground level), if the window well is less than 44 inches deep, the minimum area can be 5.0 square feet 3 8.
- Minimum Dimensions: The opening must be at least 24 inches high and 20 inches wide 3 4. It's important to note that a window that is 20" x 24" only provides 3.33 square feet, so it must be larger to meet the 5.7 sq. ft. area requirement.
- Maximum Sill Height: The bottom of the window opening can be no more than 44 inches above the finished floor 3 9. This ensures occupants, including children and elderly individuals, can easily reach and exit through the window.
- Operability: The window must open fully from the inside without the use of keys, tools, or special knowledge. Locks and screens cannot impede the opening operation 9 2.
- Tempered Glass: For safety, egress windows in hazardous locations-such as those within 24 inches of a door, near stairs, or in bathrooms-typically require tempered or safety glass 1 4.
The Crucial Role of Window Wells
If your egress window is installed below ground level, a window well is required. The well itself has its own set of rules:
- Size: The well must provide at least 9 square feet of horizontal area (e.g., 36" x 36") with a minimum projection of 36 inches from the window 8 4.
- Ladder or Steps: If the well depth exceeds 44 inches, permanent steps or a ladder must be installed to allow escape 3 9.
- Drainage: Proper drainage at the bottom of the well is essential to prevent water from pooling and leaking into your basement. This often involves a gravel base and a drain pipe connected to a storm sewer or sump pump.
The Beaverton Permit Process: A Step-by-Step Guide
Installing an egress window in Beaverton always requires a building permit from the City of Beaverton Building Department 10 11. Skipping this step can result in fines, forced removal of the work, and problems when you sell your home. Here's how the process typically works:
- Pre-Application Consultation: Before you start, it's highly recommended to contact the Beaverton Building Department directly. They can clarify local interpretations of the code, provide application forms, and answer specific questions about your property 10 12.
- Prepare Your Plans: You or your contractor will need to submit detailed plans. These usually include a site plan showing the window's location on your home and construction drawings that detail the window's dimensions, sill height, framing, and window well specifications 10 3.
- Submit Application & Pay Fees: Submit your completed application along with the plans and the required permit fee. Fees in Beaverton are variable but typically range from $50 to $500, depending on the project's valuation and complexity 10 5.
- Schedule Inspections: Once the permit is issued and work begins, you must schedule mandatory inspections. These usually include a framing inspection (after the hole is cut and framed but before the window is installed) and a final inspection to ensure everything is completed to code 10 11.

Cost Breakdown for Egress Window Installation
The total cost for an egress window project in Beaverton is more than just the price of the window. It's a complex construction job that involves multiple trades. Here's a general breakdown of what to expect:
- Window & Basic Labor: The cost for the egress window unit itself and the labor to install it in an above-grade opening typically starts between $2,600 and $5,800+ 10 5.
- Excavation & Window Well Work: For below-grade installations, the most significant cost adder is the excavation. This involves digging out the soil, cutting through the foundation (which may require a concrete saw), installing the window well, and ensuring proper drainage. This phase alone can add $1,000 to $2,000 or more to the total project cost 10 9.
- Professional Services: Given the complexity-involving masonry, waterproofing, and structural work-this is not a DIY project for most homeowners. Hiring a licensed contractor who specializes in egress windows is crucial. They will manage the permit process, ensure code compliance, and coordinate the various skilled laborers needed 5 13.
Choosing the Right Egress Window for Your Home
When selecting a window, you have several options that meet code. Common choices include:
- Casement Windows: These are a popular choice as they typically open fully, providing the entire window area as clear opening.
- Double-Hung Windows: Some double-hung models can meet egress requirements if both sashes are removable from the inside, providing the full clear opening.
- Sliding Windows: Like double-hung windows, certain sliding windows can comply if they provide enough unobstructed space.
Your choice will depend on your home's style, your budget, and the specific spatial constraints of your basement wall. A qualified installer can help you navigate these options.
Why Professional Installation is Non-Negotiable
The stakes are high with egress window installation. Mistakes can lead to structural damage, chronic water leaks, mold growth, and-most critically-a window that fails to provide a safe escape during an emergency. Professionals bring expertise in:
- Structural Integrity: Safely cutting through foundation walls without compromising your home's stability.
- Waterproofing: Installing proper flashing, drainage, and sealing to keep your basement dry for years to come.
- Code Mastery: Ensuring every detail, from the window well ladder to the latch mechanism, meets Beaverton's specific requirements, saving you from costly corrections and failed inspections 13.
Always verify a contractor's license and insurance, and ask for references from past egress window projects specifically.
