I have a door leading from my basement, (finished, livable, but still rough compared to the rest of the house) to the drive-under garage. This door isn't to code in the slightest: it's an interior door rather than a 20-minute fire door as is required for garage-entry; it's a hollow core door with the top cut off and open; and it has lots of space to gap and draft. As such I want to replace it with something more appropriate and code-compliant.
However, some problems arise when trying to do so, namely that the door is 78" tall rather than the standard 80". It's also elevated on a row of bricks, which serves as a tripping hazard. I would like to remove those bricks to fit a standard, code-compliant door. What purpose do those bricks serve, and what risk might I introduce by removing them? Can I remove them? Should I?
I haven't found anything related to any code-compliance with regards to an elevated door. The only purpose I can think that the bricks might serve is flood-prevention.
