Roof Access Hatch

Recommended Posts

If there is an attic of height greater than 30" the 2014 Oregon code requires access to the attic. Hatch must be at least 22"x30". No mention of access to the roof being required.

Since Oregon's 2014 codes are adapted from the 2009 IRC, I suspect that others may be the same.

IBC 1209.3 Mechanical equipment and appliance access.

The AC unit for the unit I inspected was on grade but I have no idea if there are mechanical components up there.

I've gotten directly conflicting reports from CCBD. Some of it falls under Fire adept. Reg's, some under accessibility for inspection, but no blanket requirement I've found.

Chicago isn't on IRC, so if you're looking for some legal basis, you'll have to dig through DCAP, Fire, and maybe Div. 15 in the CCBC.
