I'll put it straight, being Zoner won't save you if you don't play along with local forces.
Check the Laws of Sirius, the system you want to build in is either House space, or borders some kind of territory, and is then likely claimed, regardless of what the great map of Sirius shows. You'll have to check each charter to see who has claim to what, in some cases, systems may be claimed by more than one entity.
So you can either reveal yourself and ask permission in advance, I'd reccomend this if you plan to build it near anything or near any traversed routes. It won't remain hidden for long, and its better to be open about it, unless you're looking for a fight. However, if you built first, most 'entities' will work with you so long as you communicate and comply with their regulations.
Or, if you fear you will not get permission or simply don't want to involve local powers, find a good secluded spot and build anyways. If you are trying to build a zoner freeport-like base, I'd go with the open disclosure. It will be costly though, but if you plan to get good use out of it, and have others helping you, that shouldn't be a major problem.
