June 11, 2012 George Thompson 3737 Blackhawk Rd agan, MN 55122 Re: request for exception to the current building code Mr. Thompson: Your request for an exception to the requirement for a minimum 36" width for a stairway (section R- 311.5.1)in the 2007 Minnesota State Building code is accepted. The existing construction does not allow room for more than the existing, 34" width without extensive reconstruction. Your request for an exception to the maximum riser height of 7 -3/4" is denied. Based on the dimension that you have provided, the existing opening in the floor should allow for the new stair framing to meet the rise, run and headroom requirements of the current code. See section R -311.5 attached. If you have any further questions, please feel free to contact me at 651 - 675 -5680. Thank You for your cooperation, ‘/Al Jeffrey T Wheeler Building Inspector City of Eagan 651 - 675 -5680 ATTACHMENT TO 2012 RESIDENTIAL BUILDING PERMIT APPLICATION SITE ADDRESS: 3737 BLACKHAWK ROAD To whom it may concern regarding the reinstallation of my stairs and meeting the current code for a stairwell: To rebuild the stairs in my home, which were originally constructed in the tatter 60's, I would like to request 2 exceptions from the stairway code: 1. The finished width will be approx 34 1/2" rather than 36 ". After removing the 2 layers of wallboard on each side of the stairwell, from my floor rim joist to the ibeam on the opposite side is 35 1 /2 ". By installing 1 /4" wall board on each side will leave a width of approximately 35 ". The only way to attain the 36" would be to move the entire kitchen wall and the floor rim joist which would negatively impact the structural integrity of my home itself, Op, piiN P 2. The sunroom /kitchen now has a tile floor and consequently the rise of the top step is 8 3 /4 ". All the remaining steps have a 7 3 /4" rise. Again in order to change the rise of the top step would require removing the floor /ceiling joist AND cause me to remove a door in my den as the door width wouldn't be wide enough.
