If you want a bullet proof gold plated soloution the other posters are generally correct.
BUT I consider an informal arrangement perfectly acceptable so long as a majourity of the owners at a general meeting pass a motion approveing it and strict conditions are applied. The money should go into the Admin fund and it would be taxed at the company tax rate of 30%.
Even if one owner strongly objected he would have to win at CTTT to get the motion overturned and then the only penality might be you would have to stop the rental. It’s only if you ignored the CTTT ruling that you might be liable for a fine.
I’ve no idea what a licience is or how much they cost, but I suspect they would need to be drawn up by a lawyer costing mega bucks.
Don’t even consider Exclusive use motion as this is a permenent transfer of the room to the requester unless he pays the Strata market value for purchaseing the room.
