Adding an egress window to a basement bedroom is a great way to increase the value of your home and bring in more natural light. However, it is more than just a value-add. In many places, it is a legal requirement for a basement to have an egress window if it is to be used as a bedroom or habitable space. This is because egress windows provide a means of escape in the case of an emergency, such as a fire.
The International Residential Code (IRC) sets out specific requirements for egress windows, including minimum dimensions and the need for a window well and ladder for windows below ground level. These requirements vary slightly depending on the region, so it is important to check the local building codes before installing an egress window.
The cost of installing an egress window can range from $500 to $5,000, but it is generally a worthwhile investment, adding natural light, ventilation, and safety to a basement bedroom.
What You'll Learn
Egress windows are required for basement bedrooms by law
The size and shape of egress windows are governed by state and local laws, as well as international building code guidelines. The IRC mandates that egress windows must be large enough to provide an exit from a room in an emergency, with a minimum clear opening of 5.7 square feet, a height of at least 24 inches, and a width of at least 20 inches. The sill height must not exceed 44 inches from the floor. These dimensions are designed to ensure that occupants can escape quickly and easily, and also allow first responders to enter the building with their gear if needed.
In addition to the IRC requirements, individual states and cities have their own set of codes that building owners must follow. These codes are designed to ensure the safety of occupants and the public in case of emergencies. Therefore, it is essential to check the specific requirements for your location before installing an egress window to ensure compliance with all relevant regulations.
Basements that are unfinished, do not have any livable space, and do not have full-height foundation walls are typically exempt from requiring egress windows. However, if the basement is a habitable space or used for sleeping, an egress window is necessary to make it a legal bedroom. This includes basement bedrooms that are rented out to tenants, as safe exit options in case of an emergency are mandatory.
Egress windows offer benefits beyond safety, such as increasing natural lighting and ventilation in the basement. They can also add to the overall style of the home and increase its value, especially when converting the basement into a bedroom.
In summary, egress windows are required by law for basement bedrooms in the United States to ensure compliance with safety regulations. The specific requirements may vary depending on the location, so it is important to consult local building codes and guidelines before installing an egress window.

Egress windows increase the value of a home
Egress windows are a valuable addition to any home, offering increased safety, improved natural lighting, and enhanced living space. They are a crucial safety feature, providing a clear and easily accessible escape route in case of emergencies such as fires. For a basement to be considered a legal bedroom, it must have an egress window installed.
The impact of egress windows on a property's value can vary depending on location, size, quality, and the overall condition of the home. However, it is widely recognized that they can significantly boost the resale value of a home, especially in a competitive housing market. According to a general manager at Foundation King, egress windows can add an average value of $20,000 to a home.
Egress windows are typically larger than standard basement windows, allowing more natural light to enter and reducing the need for artificial lighting. This makes the basement a more inviting and comfortable space. Additionally, egress windows improve ventilation, reducing dampness in the basement.
Another benefit of egress windows is their ability to enhance the functionality and appeal of a basement. When selling a home, prospective buyers are more likely to be attracted to a property with a finished and safe basement. Egress windows allow homeowners to legally market their basement as an additional bedroom, home office, or family room, increasing the overall living space and, consequently, the value of the property.
The cost of installing an egress window can vary depending on various factors, but it typically ranges from $500 to $5,000. While this entails an initial investment, the potential return on investment (ROI) justifies the upfront costs. Many homeowners find that the ROI of egress window installation is well worth it, especially when considering the increased property value, improved safety, and enhanced living space.

Egress windows improve natural lighting and ventilation
Egress windows are a great way to improve the natural lighting and ventilation in a basement. The larger size of egress windows compared to regular windows means more sunlight can enter the basement, making it a brighter and more inviting space. This can have a positive impact on the mood and well-being of those using the space. The increased natural light can also reduce the need for artificial lighting, leading to potential energy cost savings.
In addition to improved lighting, egress windows can also enhance airflow and ventilation in the basement. Proper ventilation helps to reduce humidity and prevent the growth of mould and mildew, creating a healthier and more comfortable environment. This is especially beneficial for basements, which are prone to moisture and poor air circulation.
The combination of increased natural light and improved ventilation can transform a basement into a functional and welcoming space. With egress windows, basements can become ideal locations for hobbies, workouts, or even a home office. The improved lighting and ventilation can also increase the overall value of the home, making it more attractive to potential buyers.
Egress windows not only improve the natural lighting and ventilation of a basement but also serve a critical safety function. They provide a means of escape in case of an emergency, such as a fire or natural disaster. The size and positioning of egress windows are regulated by building codes to ensure they are effective escape routes. Therefore, by installing egress windows, homeowners can enhance the safety, comfort, and value of their basement spaces.

Egress window wells must meet certain specifications
Egress window wells are an essential component of basement egress windows, providing a safe means of escape in case of an emergency. They are required by building codes for finished basements and play a crucial role in transforming a basement into a habitable space. Here are the key specifications that egress window wells must meet:
Minimum Size Requirements
The International Residential Code (IRC) sets specific criteria for egress window wells. Firstly, the window well must provide a minimum of 9 square feet of floor area. This translates to a minimum width and length of 36 inches, as stipulated by the IRC and confirmed by several sources. Ensuring this minimum size is crucial for allowing occupants to escape safely and providing enough space for rescue personnel to enter if needed.
Ladder or Steps
If the window well exceeds a depth of 44 inches below grade, it must be equipped with a permanently affixed ladder or steps. This addition facilitates a quicker and safer escape for anyone using the egress window. The ladder or steps must meet specific requirements:
- A minimum width of 12 inches
- Projecting at least 3 inches from the window well
- Spaced no more than 18 inches apart vertically
- Not encroaching more than 6 inches into the required window well dimensions
Window Well Cover
While not directly related to the window well itself, a window well cover is essential for safety. It prevents family members, pets, or friends from accidentally falling into the large opening. A well-designed cover can be lifted from below, ensuring easy escape during emergencies while providing protection from accidental falls under regular circumstances.
Compliance with Building Codes
Egress window wells must adhere to local and state building codes. While the IRC provides a baseline for the specifications mentioned above, it is crucial to consult your local building department or city offices to understand any additional requirements specific to your area. These requirements are in place to ensure that your egress window well installation meets all necessary safety standards.

Egress window installation costs vary
Egress windows are required in all finished basements before they can be legally converted into a living space. The cost of installing an egress window varies depending on several factors, including the size of the window, the type of window, the complexity of the installation, and the contractor's experience.
On average, egress window installation costs range from $2,500 to $5,500, but many homeowners pay around $4,000. The cost of the window itself usually falls between $100 and $700, depending on its size and quality. The real expense typically comes from the installation costs, which can range from $40 to $100 per hour.
If you are installing a below-ground egress window, you will also need to factor in the cost of a window well, which can range from $200 to several thousand dollars, depending on its quality and whether it is prefabricated or custom-made. Additionally, you may need to hire a land surveyor and structural engineer to ensure your foundation remains intact, which can cost $300 to $1,500 per visit.
For a fully outsourced egress window installation, you can expect to pay $4,000 to $7,000 for a smaller window. If you choose to dig the hole for the window well yourself and outsource the foundation cut and installation, the cost is typically around $3,300.
It is possible to install an egress window yourself, but it is important to ensure you have the necessary tools and permits, and it may be difficult to obtain permits or comply with local regulations.
