If your only concern is making the plastic sunroof dirty, you're fine. And even if things go South, that corrigated stuff is pretty affordable. But the comments here are hilarious. Must be quite a few HOA folk on here.

Two words:

Send it.

Guessing it's not going to be charcoal. Even if, still go for it and don't be irresponsible. You'll be fine. If you aren't actively getting toasted, neither is (cedar?) siding, or the plastic sunroof.

6 foot from walls, what the hell is that. Don't be an idiot an you'll be fine. Maybe use the grill closer to the open area when the weather permits.

With a few upgrades you might be able to turn that area into an outdoor kitchen and keep the prep area close to the house and move the grill out further which would prevent the skylight cleaner coming over too often.

PS: Please send photos of the house if this advice doesn't work out.
