Egress Window Questions, Answered Straight

Wichita amends IRC R310. The opening needs 4.5 square feet of net clear opening with the window open and a 5.7-square-foot break-out area; a minimum height of 19 3/4 inches for single-hung, double-hung, and awning windows; and a minimum width of 17 inches for casements and sliders or 30 1/4 inches for hung units. The model code asks for 5.7 square feet net clear, 24 inches high, 20 inches wide. We size every unit to satisfy both, and the amendment leaves the model 44-inch sill limit in place.

The opening you get after a removable sash or panel is taken out, as opposed to the opening with the sash simply slid or swung open. Wichita's code lets the everyday open position be 4.5 square feet as long as the break-out condition reaches 5.7. Not every window has a removable sash, which is why we show the math for the specific unit on the quote.

A below-grade egress window needs a well of at least 9 square feet projecting at least 36 inches from the wall (the model code figure, which the local amendment does not change). Wichita's amendment then requires a permanently affixed ladder in any well deeper than 44 inches, with rungs at least 12 inches wide, projecting 3 inches, spaced no more than 12 inches on center, plus a rated cover or guardrail on any well deeper than 30 inches, plus 12 inches of washed gravel under the well unless it drains into the foundation drain.

Typically $3,500 to $6,500 in the Wichita area for the complete job: excavation, concrete cut, window, well, ladder, cover, drainage, backfill, and inspection. Block foundations often land near the lower end; deep digs, tight access, or a composite well can pass $7,000. Full breakdown on our pricing page.

Yes. Cutting a foundation opening requires a building permit and a final inspection. In Wichita and unincorporated Sedgwick County that is MABCD, the Metropolitan Area Building and Construction Department. Your installer files it and passes the fee through at cost; MABCD's Table B prices a $3,500 to $6,500 remodel at roughly $92 to $125.

No. Derby runs its own building office, its own contractor licences, and adopted the 2024 IRC effective January 1, 2026. Haysville, Park City, and Valley Center also run their own offices. Andover adopted the Wichita/Sedgwick County code by its own ordinance and takes an MABCD licence plus a certificate of insurance. Maize and Goddard contract with MABCD. We file with the right desk; each city page on this site says which.

Yes. R310 requires an emergency escape and rescue opening in every sleeping room. Two basement bedrooms means two compliant openings. One shared window in the hallway does not satisfy the code.

A compliant egress opening is the requirement appraisers and inspectors check first, and adding one is how a 'three bed plus den' becomes a legal four-bedroom. We build to the Wichita code and the model code both, but we will not guarantee any appraisal or inspection outcome. Those calls belong to the appraiser and to MABCD or your city.

Sedgwick County Emergency Management's guidance for the home is the basement, a safe room, or the lowest and most interior room away from windows. The egress window is not where you shelter; it is the exit you use once the storm passes and the stairs may not be an option, and the way a firefighter reaches you. Put the sheltering spot on the far side of the room from the glass and keep the well clear so the window opens.

Sedgwick County is EPA radon Zone 2. In the Kansas Radon Program's 2010 data the county's average tested home was 3.6 pCi/L, under the 4.0 action level, but 30.9 percent of measurements came in at or above it. Test before drywall. Mitigation and egress do not conflict; sequence both before the walls close.

One to two days on site for a single window: dig and cut day one; set, well, drainage, and backfill day two. Add permit lead time up front, and window orders can add a week or two depending on the unit.

Poured concrete and concrete block are both routine. Poured walls get diamond-blade wet sawing; block walls come out course by course. The older stone and early concrete foundations in College Hill, Riverside, and Delano need evaluation first; some are fine, some need a different plan. That is what the free on-site measure is for.

Not when it is done right. The opening gets a properly sized lintel or header where the structure requires one, and a pressure-treated buck frame anchored to the concrete. Undersized headers and unsupported cuts are the cheap-install failure mode. It is a fair question to ask any bidder exactly how they will carry the load over the opening.

Drainage is the difference between an egress window and a basement leak, especially on the Group D clay under most of Wichita. Wichita's code requires 12 inches of washed gravel under the well or a tie-in to the foundation drain; we do that, add an outlet where the footing drain is silted or missing, and grade the backfill away from the house. A rated cover keeps the May storms out of the well itself.

Most of it. Wichita's code frost depth is 24 inches, so winter digs are often possible. The two slow windows are the hard-freeze weeks of January and February and the May-June saturation, when NOAA's normals put over 10 inches of rain on the city in eight weeks. Fall is the easiest season: dry ground, permit in hand, room finished inside over winter. Window swaps in existing openings run year-round.

Usually not. If the opening and window are compliant, a well replacement runs $1,000 to $3,000 and a drainage rebuild $300 to $1,000. If the steel still has structure, a liner is $400 to $900. We swap or reline the well, rebuild the gravel bed to the 12-inch rule, anchor a ladder if the depth requires one, and fit a rated cover.

If you are anywhere in Wichita, from the older cores of College Hill, Riverside, and Delano to the 1950s ranch belt and the newer subdivisions on the edges, yes.
