Depends on the slope, not the height. If it's less than 1:20, not a ramp.Hello!
I'm working on an outdoor patio deck for a restaurant. I want to know what's the min height that the code requires to have a ramp. If it is less than 6" do I need to have a ramp and handrails/ guardrails? thanks!
If it is a ramp, I think you're looking for 1003.5.it is not a tripping hazard? where can I find it in California Building code? Thanks!
Likely it is egress also. It's hard to imagine how it wouldn't be. If so, you need to meet both requirements. If it is a ramp, you will need to meet 1003.5 handrail requirements which are more stringent than ADA/ANSI 405.8.1003.5 is for egress. I need accessibility req.
You need to be less than 1:20 to not be a ramp. All egress/accessible ramps need to be less than 1:12.i think i have the space to be less than 1:12.
More than likely landings will not be required because the sloped surface is going between 2 floor areas, the floor areas would qualify landings the separate landings would not be required.You need to be less than 1:20 to not be a ramp. All egress/accessible ramps need to be less than 1:12.
Consider also that a ramp needs a landing at the top and bottom. A 6" ramp at 1:12 with 60" landings will be 16' long.
A 6" rise in a sloped walking surface at 1:20 will be 10' long, no landings, guardrails, handrails, contrasting colors required.
ADASAD 405.8 doesn't require handrails for a 6" high ramp. I think ANSI A117.1 is the same.
IBC, ADASAD and ANSI Do not apply in CA.I think this might be what you are looking for:
IBC 1104.2 Within a Site
At least one accessible route shall connect accessible buildings, accessible facilities, accessible elements and accessible spaces that are on the same site...
Changes in level greater than 1/2" in height shall be ramped...
