I'm planning to install a set of attic access stairs in our attached garage. Currently we have an access panel there, but we plan to put some attic storage up there, and a ladder just ain't gonna hack it! I looked into it, and because the attic space over that garage isn't 'walled-off', the drywall between the garage and the attic/house is the firewall. That means that if I install an attic access staircase, it needs to be fire-rated (per the local building inspector).
Unfortunately that means the attic stairs are going to be HELLA expensive!! The cheapest set of stairs I found was a steel set, and they were over a grand. So, I'm wondering: What if I built a five-sided box over the non-fire-rated access stairs, that was drywalled...
