Sorry for causing confusion. The IRC, International Residential Code, is the code that virtually everywhere in the US uses for one and two family residential structures,up to three stories high. There is an online version available. New versions come out every three years. It is not uncommon for a building jurisdiction to be one or two versions behind.
Structural, electrical, plumbing, etc.is all in there, in one "rule book". States, towns, cities, municipalities may opt out of certain sections if they desire.
It was posted that a stair nose had to be 1". I pointed out the IRC, used as a basis for virtually everywhere in the US, states a stair tread nose overhang of 3/4 to 1-1/4 inch, and then only if the tread depth is less than 11 inches... While it is possible that a local jurisdiction might choose to say 1", it is not likely IMO. However, as with many things to do with construction, it is always best to be acquainted with the rules that are used where the building in question is located.

Nice looking stairs darz, but there would be a problem with those branches that make up the ballusters. Lots of places for a kid to get stuck and hang by their neck. That is why we have the 4" ball rule.... openings cannot be any larger than 4". The reason being that a larger opening may allow a child's body to pass through and then the child may get hung by the neck when the head cannot pass through. Similar rule on cribs for kids. I would hate to build something as creative and then have a grandchild die as a result.
