The town I'm working in has no zoning/building officials and only very vague zoning bylaws so they're no help. The subject property has a deck above 4' with top and mid railings but no pickets/ballisters. It's solid, but a little kid (or skinny adult) could dive right thru them. My client states his "FHA specialist" says it makes no difference since there is no local code. I know they are supposed to withstand 200lbs horizontally and thought there was a limit on the size of the openings but can't find anything specific.
