Steps all Around Two Sides on Sloping Ground
I am building a floating 14 by 20 cedar deck (max height is 18 inches) and wish to have stairs all around two adjacent sides. The other two sides are bordered by a fence (14 ft side) and a garage (20 foot side).
The ground in front of the open 20 foot side is fairly level. However, on the 14 foot side, the ground slopes down 6 or 7 inches (away from the garage).
I have tried to look at various internet videos concerning deck stair installation, but am unable to decide how to proceed. I am assuming there will be two steps on the highest side (a third will be the top of the deck) nearest the fence and eventually, only 1 (a second being the top of the deck) on the lowest side.
How or to what do I secure the stringers at ground level before proceeding with the risers and treads.
I am hoping to avoid pouring a long slab all around the entire deck but will do so if necessary.
Will precast cement pads work?
I am planning on cutting all the stringers the same, then start by attaching the first stringer at the highest point of the deck (next to the fence), then attach each successive stringer, working my way along the level 20 ft side, and then turning the corner and cutting off the bottom of each stringer as I get closer and closer to the garage - gradually eliminating the bottom step.
My construction skills are limited, but I am a careful worker.
