The DA seems to allow hotel/motel style lets “with permission”. That means they can’t be allowed without permission.
But to clarify, you’d do well to get a by-law that says something like the DA doesn’t allow short-term lets without permission and the strata scheme reserves the right to withhold permission for short-term holiday lets on a case by base basis.
Basically, you need a strata lawyer to create this by-law for you … or wait until the new short-term letting strata laws come in.
