coda: Do you mean it is not compliant? If so, why?

Outside the building, code may not apply?

 

[TheCommish]

Commish: Yes, you’re right, this is single family residential so CRC would apply. I only placed IRC diagram for reference of code intent. The height requirement for guardrail for CRC would be 42”. My question to everyone is, please tell me if it is compliant with CRC and if so/not explain.

[TheCommish]

Mark, is this the Canadian code, or California, that will screw me up

Commish: Sorry, this is the California Residential code. Wording of code identical to that in the California Building Code.

 

[TheCommish]

So it thought Massachusetts was special with its odd modification to the model codes

 

[mark handler]

Comish
I cited the California Codes
California has you beat for the odd and unique modifications to the model codes.
