"Curious—did anyone run into permitting issues when making structural changes like that?"

Yeah, I've wondered about this too... seems like modifying trusses could open a whole can of worms with permits and inspections. Has anyone here actually had an inspector flag something like that? Or maybe had to get an engineer involved after the fact? I'd imagine that could get pricey pretty quick.

I've seen inspectors flag modified trusses a couple times, actually. Usually, the process goes something like this: inspector notices the modification during a routine check, then requires an engineer's stamp to verify structural integrity. At that point, you're looking at hiring a structural engineer to assess and possibly recommend reinforcements or corrections. It can definitely get pricey and time-consuming, especially if you have to redo work you've already completed. Better to get an engineer involved upfront if you're planning significant changes... saves headaches later.

Yeah, definitely agree with this. I've seen inspectors get picky even over seemingly minor alterations—like cutting or drilling into trusses for wiring or plumbing. Had a buddy who thought he'd just notch a truss slightly for some ductwork, inspector caught it and he ended up shelling out quite a bit for an engineer's report and repairs. Makes me wonder how often these small modifications actually cause structural issues down the road...

I've wondered the same thing, honestly... like, are inspectors just being overly cautious or do those minor cuts and notches really add up over time? I get why trusses are engineered precisely—each part is carrying a specific load—but does shaving off a tiny bit here or there really compromise the whole roof system? Seems extreme.

Still, hearing your buddy's story makes me rethink my own plans. I was actually considering something similar to run some extra wiring through the attic. Maybe rafters would be easier to work around for future DIY projects? Or is that just trading one set of headaches for another? Guess there's no perfect solution when you're trying to balance structural integrity with practicality...

Yeah, I've had similar thoughts about inspectors being overly cautious, but honestly, those small cuts can add up quicker than you'd think. A buddy of mine did some minor trimming to fit ductwork through his trusses—nothing major, just a notch here and there—and ended up with noticeable sagging within a couple years. Rafters might give you more flexibility for DIY stuff later on, though they come with their own set of issues like needing interior load-bearing walls or beams. Always trade-offs, right?
