The 18-inch rule does seem arbitrary until you see what happens when someone tries to cut corners.
I’ve seen that firsthand—previous owner in my last place ignored the clearance around outlets, and we ended up with a slow leak behind the vanity. Didn’t notice until there was a musty smell and some warped trim. Ever since then, I stick to the letter of the code, even if it feels like overkill in the moment. It’s way less stressful than dealing with repairs after the fact.
- Totally get the frustration—those "arbitrary" rules usually have a reason, even if it’s not obvious at first.

Couldn’t agree more. I’ve had to rip out drywall because someone tried to fudge outlet spacing near a tub.Even if it feels like overkill in the moment. It’s way less stressful than dealing with repairs after the fact.
- Curious—did your inspector flag anything else that surprised you? Sometimes they catch stuff I’d never think of, like venting or weird GFCI placement.
Definitely agree about the rules—sometimes they seem nitpicky, but there’s usually a safety angle folks don’t see right away. I’ve seen inspectors get really particular about fan venting, especially if it’s dumping into an attic instead of outside. That’s a mold nightmare waiting to happen. GFCI placement is another one… I’ve had jobs where they insisted on a GFCI even for a light switch near a shower, which felt like overkill at first, but honestly, I’d rather be safe than sorry. It’s wild how much you learn just by going through the process.
I get what you mean about the rules feeling over the top sometimes. When we did our bathroom, I couldn’t believe how picky they got about the venting too—I just figured a fan was a fan, right? Turns out there’s a ton of stuff that can go wrong if it’s not done right. The GFCI thing threw me at first, but after reading some horror stories online, I’m kinda glad they’re strict about it. I guess it’s one of those things you don’t appreciate until you see what happens when people cut corners.
Yeah, the venting rules tripped me up too. I thought as long as the fan was powerful enough, it’d be fine, but the inspector wanted to see the duct size, the run length, even the termination point outside. It felt nitpicky at first, but I’ve seen what happens when moisture gets trapped—mold city. GFCIs are another one where it seems like overkill until you hear about someone getting zapped. The hoops can be annoying, but I’d rather deal with them than a flooded ceiling or worse.
