## Egress windows for Twin Cities basements An egress window is what turns a finished basement room into a legal bedroom. It is also the single most common reason a basement bedroom fails inspection. We cut the opening, install the window and well, handle drainage, and get it inspected. ### What the code asks for - **5.7 sq ft** net clear opening (5.0 sq ft when the opening is at grade) - **24 inches** minimum clear opening height, **20 inches** minimum width - Sill no more than **44 inches** above the finished floor - A window well at least **36 inches** out from the wall and **9 sq ft** in area - A **permanently attached ladder or steps** when the well is deeper than 44 inches - Opens from the inside with no key, tool, or special knowledge ### What the install involves 1. Locate utilities and confirm the opening does not land on a beam pocket or service 2. Saw-cut the block or poured foundation and remove the material 3. Set the header/lintel and frame the rough opening 4. Install the casement or sliding window, flash, insulate, and trim 5. Excavate and set the well, tie into drain rock or the drain tile so it does not fill with water 6. Backfill, grade away from the house, add the cover and ladder 7. Interior finish, then inspection ### Rough cost in the Twin Cities | Scenario | Typical range | |---|---| | Enlarging an existing basement opening | $2,500 – $4,500 | | New cut in block foundation, standard well | $4,500 – $7,500 | | Poured concrete wall, deeper well, drainage work | $6,500 – $10,000+ | Frost depth, egress well drainage, and how far you are hauling spoil off a tight city lot are what move the number in Minneapolis and St. Paul. ### Why it is worth it Nothing else unlocks a rentable basement bedroom the way an egress window does. It is usually the difference between a $0 rec room and a room that carries rent every month — and it makes the basement safer for whoever sleeps down there.
