Get My PriceThe premium choice for a rental or mother-in-law apartment.
Ours start at $18,500. That covers engineering, the permit, excavation, the door cut, two engineered concrete walls, and a wide stairway with landings. Railings, longer runs, rock, and a walkway to the street add cost. With railings and flatwork, most land between $18,500 and $24,000.
Width and feel. A five-foot stairway coming straight off the house walks like a front entrance. If the basement will be a rental or a mother-in-law apartment, this is the version guests and renters love.
Most Utah cities require one before a basement can become a legal apartment or ADU. A walkout entrance checks that box, and adds the daylight and dignity that make the space rentable.
Plan on 15 to 20 feet coming off the house, depending on basement depth. The engineer sets the exact run. Send your address and we'll check your lot for free.
When the drop next to the stairwell is more than 30 inches, code requires a guard. We price black powder-coated steel railing as a clear line item, so you choose with real numbers.
