Window well has no ladder: when code requires one in Fort Collins and what it costs

A window well deeper than 44 inches that serves an emergency escape opening needs a permanently attached ladder or steps under the code Fort Collins enforces. Without one, the room behind it is not a compliant bedroom, and an inspector will say so. Adding an anchored ladder to a sound well usually runs $350 to $1,100. If the well is also short on size or rusted, it is replaced with the ladder built in at $1,100 to $3,300.

Check this first (a tape measure)

Measure the depth. From the grade at the rim to the bottom of the well. Over 44 inches, a ladder or steps is required. At or under 44 inches, it is not, though one still makes a real exit easier.
Measure the projection. From the window face straight out to the well wall. Code wants at least 36 inches, and a ladder may encroach only 6 inches into that, so a well built at exactly 36 inches with a deep-rung ladder can end up short. If your well is barely 36, plan for a low-profile ladder or a step design.
Measure the area. At least 9 square feet of horizontal ground area in the well.
Check the room. Is it a bedroom, or intended to be one? The ladder rule attaches to emergency escape openings. A well in front of a laundry room window is a good idea, not a code item.
Look at the well’s condition. If the steel fails the screwdriver test at the soil line, bolting a ladder to it is wasted money. The rusted well page has the test.

What is usually wrong

What you see	Likely cause	Fix and cost
Sound well, over 44 in deep, no ladder	Ladder omitted at install, or the room became a bedroom later	Anchored ladder, $350 to $1,100
Well exactly 36 in out, ladder would encroach	Undersized for a ladder	Low-profile ladder or well replaced at 42 in or more, $1,100 to $3,300
Deep well, rusted or bowed	Ladder is the least of it	Replacement with integral ladder or steps
Deep well, visible from a finished room	Cosmetic and code at once	Composite terraced well with built-in steps
Ladder present but rungs 20 in apart or loose	Non-compliant ladder	Replace the ladder, same range
Well under 44 in, no ladder	Nothing wrong	Optional

Why this matters in Fort Collins

The City of Fort Collins Emergency Escape and Rescue Windows guide draws two compliant wells side by side. The ladder option: “required if well deeper than 44 inches,” a 6-inch maximum encroachment into the required well space, 12 inches minimum inside width, and a well at least 36 inches perpendicular to the window with 9 square feet of ground area. The stepped option: 18 inches maximum rise, 5 inches minimum run, 12 inches minimum width, and 30 inches minimum at the well base. The same guide dates the well requirement: the 36-inch well with ladder entered the city’s code on May 19, 1998, and the “ladder only if deeper than 44 inches” wording came in with the 2009 codes on October 11, 2010. A well built before 1998 was not required to have one and, per the city, a window built under an older code is still considered compliant. A bedroom finished later behind that old opening is a different story, because the basement finish permit checks the opening against the current standard. The 2024 edition renumbers the same requirements as Section R319; inspectors and older guides still call it R310.

Wells here are deep because footings are deep. Fort Collins and Larimer County both work to a 30-inch frost depth, and a basement window whose sill sits within 44 inches of the floor puts the well bottom well below grade on most lots. That is why the majority of egress wells in this market cross the 44-inch line and need the ladder.

There is one more city-specific rule worth knowing: new wells need “an unobstructed clear path to the public way,” the sidewalk or street. A gate in a fence is fine; a shed or an air-conditioning condenser parked in front of the well is not. When we add a ladder we look at the path too, because an inspector will.

Ladder or steps, honestly

An anchored steel ladder is the value choice in a corrugated well: bolted through the corrugations, rungs at code spacing, done in an afternoon if the well is sound. Steps are what terraced composite wells provide, and they are the better answer when the well is deep, when it is visible from a finished bedroom, or when the person who might need to climb out is small or elderly. The engineered kit and composite pages cover the trade-offs. Whichever you choose, the anchor is into the concrete, not into the dirt, and the well gets a fitted cover so snow does not bury the rungs.

When to call

Send the form with the depth and projection measurements and a photo down into the well. Say whether the room is a bedroom now or is about to be. If a home inspector flagged the missing ladder, the failed inspection page walks the rest of the checklist, and the well cost calculator prices ladder-depth wells on the page. We do this across Fort Collins, Loveland, Berthoud, and Greeley.

Frequently Asked Questions

Does my window well need a ladder?

If the well is deeper than 44 inches and serves an emergency escape opening, yes. The City of Fort Collins guide shows the ladder as required past 44 inches, with rungs at least 12 inches wide on the inside, spaced no more than 18 inches apart, and encroaching no more than 6 inches into the required well space. A well that is 44 inches or shallower does not need one.

What does it cost to add a ladder?

An anchored steel ladder added to a sound existing well is usually $350 to $1,100 depending on depth and whether the well needs to come off the wall to fit it. If the well is also undersized or rusted, it is replaced with the ladder built in at $1,100 to $3,300.

Can I use steps instead of a ladder?

Yes. The city's guide shows a stepped option with a maximum rise of 18 inches, a minimum run of 5 inches, a minimum width of 12 inches, and 30 inches minimum at the well base. Terraced composite wells are built this way and are the usual choice when the well is deep and visible from a finished room.

Does the ladder count against the 36-inch well dimension?

Only up to 6 inches. The guide allows the ladder to encroach a maximum of 6 inches into the required well space, so a well built exactly to 36 inches of projection with a deep-rung ladder may end up short. We measure the as-built well with the ladder in place.
