Hi All, I own an apartment in Sydney and we're having some major issues with the owners in one of the other apartments using and dealing drugs. It's causing a lot of stress to those living in the apartments and is affecting everyone's investment very negatively. We recently held an emergency meeting with all other tenants/owners to discuss. The actions of this individual have resulted in: Drug users coming and going at all hours of the night and buzzing other apartments. Keys have been cut freely and many people have been able to come and go as they please Drug users squatting in the garage and leaving faeces, syringes and other paraphernalia Noise, smells, scratches on walls etc. The owner recently had their door broken in and was robbed and assaulted (presumably due to a drug debt or related). Police were called and he himself was arrested on drugs charges, but since released and back in the apartment And the list goes on... It's a unique situation in that the man actually owns the unit, so our options in getting rid of him seem limited to null, beyond reporting everything he does to police and hoping for further arrests/charges. The unit itself is only 3 years old and is actually a designer apartment complex. Our immediate actions and next steps are to: Upgrade to security keys which can't be cut Upgrade all locks around the building Investigate the installation of security cameras ($10k+) I guess my question is around who we should be engaging to help us with this issue (lawyers? STRATA companies? (current company is not great) ) and also what other measure can we look at to protect our investment and curb what's going on? Thanks for your help!
