If a firewall is required between the garage and the house, why is it I seldom see one? Did a 3 year old townhouse this week and there was no separation at all. (Behind the studs in the attached photo is the attached garage.)
What exactly should the separation be composed of? Sheetrock? That black wall board? Should the material have any special identification??? If there is any opening at all, that would be a concern right?
I see the firewalls all the time between condo/townhome units, but I hardly ever see it between the house and garage. When did that rule come into being? If the house is a 1973 job, like my mother’s, was the code applicable then? Would you recommend installation of the firewall to an older home?
