section 1009.10 says "stairways shall have handrails on each side..."
section 1009.10 ex2 says "stairways WITHIN dwelling units, spiral stairways...are permitted to have a handrail on one side only"
reading this, in your opinions, does a deck or porch handrail on the exterior of a SFD require handrails on both sides???
and will you be enforcing it this way???
