Be sure not to confuse riser heights with headroom heights or the total height of the stair itself. Headroom is the distance between any step and the ceiling or fixtures. There are also regulations for headroom heights. You should follow other measurements if given by local building codes. These regulations are meant to reduce the risks of tripping and falling on a staircase, which are the most common home hazard. Do 2 steps require a handrail?
To get to your question - the code doesn't refer to the exterior in steps but states from finished floor or platform to finished grade in excess of 30" requires a guard rail. It's with interior they mention any stairway with more than 3 risers 2 steps will require a handrail. What is the code height for steps? Stair riser heights shall be 7 inches mm maximum and 4 inches mm minimum.
Stair tread depths shall be 11 inches mm minimum. The riser height shall be measured vertically between the leading edges of adjacent treads. How many steps require a landing? Length of flight Stairs with more than 36 risers in consecutive flights should have at least one change in direction between flights. For buildings other than dwellings, the maximum number of risers between landings should be 16 for utility stairs and 12 for general access stairs.
There should not be any single steps. Does the landing count as a step? Remember that when counting stairs, you are counting how many times you have to lift your foot. If you have to lift your foot to get onto the landing, then it counts as a step. Is there a standard height and depth for stairs?

What is minimum stair riser height for outside stairs such as for making it easier for elderly people to climb? To meet building codes requirements. That's an interesting question; you're basically extending the floor area by the width of a stair tread, right?
Why would you do that? It pushes the whole stairway out by the depth of the stair tread in move that would be unnecessary - but then I can't see your situation, perhaps I'm missing something.
I don't think we'll find an explicit prohibition in the stair codes, since the code writers can't and don't try to anticipate every possible variation on what people may invent. If she does, then the stairs would be improper as the platform would be very much too short. A platform needs to run no less than 3 ft. Experts suggest that for more physically limited people the best way avoid falls is to seek living accomodations on a single floor. Affi et als and earlier have weighted the contributions of various stair features to the risk of a stair fall, considering for example, straight versus turned stairways, with or without landings, number of steps, handraiil design, lighting specifications, and step design specifications using a tread depth of mm and a riser height of mm with a 40 mm tread nosing in a case example to state various risk contributors.

Apologies for the delay. OSHA estimates that there are 24, injuries and as many as 36 fatalities per year due to falls from stairways and ladders used in construction. Nearly half of these injuries are serious enough to require time off the job, lost workday injuries and 13, non-lost workday injuries occur annually due to falls from stairways and ladders used in construction.
These data demonstrate that work on and around ladders and stairways is hazardous. More importantly, they show that compliance with OSHA's requirements for the safe use of ladders and stairways could have prevented many of these injuries. See our book review of this publication.
