Doctor – YES …. in NSW Owners Corporations can licence residents to use Common Property and impose conditions including a fee upon those availing themselves of that in accordance with the provisions of Sect.65B of the Strata Schemes Management Act (1996).
In order to do that your Owners Corporation (O/C) needs to place an appropriate Motion on the Agenda of a General Meeting, which in order to pass requires a favourable vote by ≥75% of those owners in attendance both personally and by proxy, and with that percentage being determined on the basis of the sum lot unit entitlement of those in favour ÷ the total lot unit entitlement of those in attendance.
Be cautious though, at least initially whilst your O/C assesses the appropriateness of the conditions imposed and how well residents abide by those, and with that in mind I’d strongly suggest that the Motion if approved covers a license of 12 months, with any continuance and/or altered conditions being considered at each Annual General Meeting.
