These codes still vary by indivdual building and fire department jurisdiction.  If you are installing your windows on your own, please consult with the authority having juristdiction, prior to ordering your windows or doors.

In order to assist in research of whether the code applies to your window or door project, attached are a couple links that might help.  The best way to find out if your project falls under WUI is to give both the fire department and building department a call.  In Marin, many fire agencies cross multiple building department jurisdictions, so it is best to consult with both building officials and fire marshals.
