On a flat lot stairs are a detail. On a Bay Area hillside they are half the project: switchbacks with landings, stringers set on real footings, railings that meet code and still look right against the house.
Deck stairs, deck steps, outdoor stairs, exterior stairs, wood steps: people use all of these for the same thing, a set of steps that takes you from the deck down to the yard. That is what we build, always outdoors and always tied into a deck.
We build stairs as part of the deck structure, not an afterthought: composite or redwood treads, closed or open risers, cable, picket or panel railings. Every run is measured for consistent rise so nobody trips on the odd step.
The numbers an inspector measures are published: riser, tread, handrail and guard heights, each with its code section. We wrote them up in one place — deck stair and railing code in California.
