Out property have a slope down in the backyard and we are planning on making stairs so we could get down to the creek. The stairs will not be attach to the home and we live in Georgia. The entire length of the stair is approx. 20ft long. The problem is most site only have information on decks. My questions is:
1. Do we need a building permit?
2. The top of the stairs will have a platform anchored by four 4x4" post in the ground. How far does the post have to be from the slope?
3. Any information on the dept of the footing or requirements?
We could give you guesses, but you need to place a call to your local building inspector to get answers.
The International Residential code doesn't require permits for "decks" less than 30" above grade, so you're probably ok, if that's the code your area is under. In the city I work for, it would require a permit however. So it pays to call and ask!!!
Call your local Building department and talk to an inspector. Because the distance from top of you platform to the bottom step is >30 inches, a permit here would be required for the stairs, and they would problably inspect the footings/pier holes for the platform, just for grins and giggles. But 'here' is southern New England, where the holes to reach frost depth are 42". Yours will be considerably shallower, you lucky dog.
