Egress Windows for Bay Area Homes
Code-compliant egress window installation from Bay Area experts. Serving homeowners since 1987.
An egress window is a window designed to provide an exit in case of fire or emergency. Building codes require them in every bedroom and finished basement space. Unlike a standard basement window, an egress window meets strict size requirements, large enough for a person to exit and a firefighter to enter.

What Are Egress Windows?
The code requirements are clear. The window must provide at least 5.7 square feet of clear opening, be at least 24 inches tall and 20 inches wide, and sit no higher than 44 inches from the floor. It must open from the inside without tools or keys.
- 5.7 square feet minimum. That is the clear opening the window has to give you once it is fully open, not the size of the frame.
- 24 inches tall, 20 inches wide. Both minimums must be met at the same time, which is why an undersized basement window rarely qualifies.
- Sill no higher than 44 inches. Measured from the finished floor, so a person can reach and climb through without a ladder.
- Opens from the inside without tools or keys. No removing hardware, no hunting for a key in an emergency.
For Bay Area homeowners finishing a basement or adding a bedroom, these rules are not optional. A window that does not meet egress means the room cannot legally be called a bedroom. Insight Glass installs egress windows from Milgard, Andersen, and Anlin that meet all code requirements.
Benefits of Egress Windows
An egress window does more than satisfy an inspector. Here is what it changes for your home.
Life Safety Compliance
An egress window gives your family a reliable escape route in case of emergency. Every bedroom and basement living space in California must have one.
Natural Light and Ventilation
Egress windows are much larger than typical basement windows. That extra window size brings natural light and ventilation into below-grade spaces, making dark rooms livable.
Added Home Value
A code-compliant egress window legally converts basement space into a bedroom. In the Bay Area market, an extra legal bedroom adds real value.
Pass Inspection First
Without proper egress, a finished basement won't pass inspection. Our installs meet California building code and IRC standards every time.
Where Egress Windows Work Best
Egress windows aren't just for basements. Any room used for sleeping, or any space you plan to convert into a bedroom, must meet California's egress requirements before it can pass inspection. Here are the most common situations where Bay Area homeowners need egress window installation:
- Basement Bedrooms. Any basement space used for sleeping must have at least one egress window. This is the most common application.
- Finished Basements. Family rooms and rec rooms benefit from added light and safety.
- Bedroom Conversions. Turning a den into a bedroom? If existing windows don't meet size requirements, you'll need to install an egress window before the room qualifies.
- Older Homes. Many older homes in San Francisco and the East Bay predate modern egress codes. Upgrading brings them to current standards.
- ADU and In-Law Units. Any dwelling unit with sleeping areas requires egress windows under California permit rules.
By choosing Insight Glass for your egress window installation, you're investing in more than code compliance, you're ensuring your family's safety, adding natural light to your living spaces, and increasing your home's value with work that passes inspection the first time.

Frequently Asked Questions
At Insight Glass, we understand that egress window installation is a significant investment, and getting it right the first time is critical for both safety and code compliance. To help you make an informed decision, we've compiled answers to the most common questions Bay Area homeowners ask about egress windows, from sizing requirements to installation costs.
An egress window must meet specific size requirements, at least 5.7 square feet of clear opening, 24 inches tall, 20 inches wide. Regular windows have no such minimums and are often too small to serve as a safe exit.
A basement used for storage may not require egress. But if it will serve as a bedroom, building codes require at least one egress window. Without it, the room won't pass inspection.
Framed-wall installations run $1,500 to $3,000. Basement egress installs requiring foundation cutting and window wells range from $3,500 to $7,500. Contact us for a free estimate.
The window fails one or more code requirements, the opening is too small, the sill is too high, or it needs tools to open. The room cannot be classified as a bedroom until the window is upgraded.
Framed-wall installs take 1 to 2 days. Foundation-cut basement egress projects take 2 to 4 days. We handle all permits and inspections.
