Basement Egress Windows: What Utah Code Requires

Planning a bedroom in your basement? Before you frame a wall, there is one rule you have to know. Any room people sleep in below ground needs a safe way out. That way out is called an egress window. Here is what Utah code asks for, in plain words.

What is an egress window, and why does it matter?

Egress just means a way out. An egress window is a window big enough for a person to climb through and get outside fast.

The reason is simple. If a fire blocks the stairs, the people sleeping downstairs need a second way out. A small window high on the wall will not do it. That is why code sets real sizes.

This is not just a safety rule. A bedroom without an egress window is not a legal bedroom. When you go to sell or refinance, an appraiser will not count it. So that finished room can stop counting as a bedroom on paper. Doing it right keeps your home worth what it should be.

The real Utah code numbers

Utah uses the building code that most states use. The numbers below are the ones your city inspector will check. Get these wrong and you fail inspection. Get them right and the room is safe and legal.

One thing trips people up. You cannot just hit the 24 inch height and the 20 inch width and call it done. You also have to hit the 5.7 square foot total. A window that is exactly 24 inches by 20 inches is not big enough on its own. The window usually has to open a bit wider or taller to reach the full 5.7 square feet.

That math is part of why this is worth handing to a pro. We size the window so it clears every number at once, not just one of them.

The window well and the ladder

Most basement windows sit below the ground outside. That means you also need a window well. A window well is the open dug-out space outside the window that lets light in and gives a person room to stand and climb out.

The well has to be wide enough for the window to swing or slide open all the way, and big enough for a person to get out. And here is the part people forget. If the well is deeper than 44 inches, code says it needs a fixed ladder or steps. That way a child or an adult can actually climb up and out, not just open the window.

You also need a permit

Cutting an egress window means cutting into a concrete foundation wall. That is a big deal, and your city wants to see it done right.

So a permit is required. The city sends an inspector to check that the cut, the new header above it, the window, and the well all meet code. Skipping the permit can come back to bite you at sale time, when an unpermitted bedroom shows up and slows the deal.

How Lynnwood handles all of it

Here is the good news. You do not have to learn any of this or chase any of it. When we finish a basement bedroom, we handle the whole egress job from start to finish:

• We pull the permit with your city.
• We cut the foundation wall the safe way and set a proper header above the opening.
• We install an egress window that clears all the size rules at once.
• We dig and set the window well, and add a ladder when the well is deep.
• We meet the inspector and get it signed off.

One crew, one written price, and Dakota runs the job. You get a legal, safe bedroom and you never have to read a code book.
