Blueman – Does your scheme have a Visitor’s Car Park by-law? If it does then it is up to the scheme itself to decide how strictly they enforce the by-laws. Some schemes have a 3 hour limit on Visitor car parking but other schemes have no limit. In the case of no time limit then this defaults to the position of a “reasonable” time limit. These limits general depend on whether there is an on site building manager whose job it may be to police the time limits.
It is my understanding that the council rangers may have the authority to ensure that the number of visitor car spaces is as per the development plans but it would not be within their job description to mandate how the scheme polices its own by-laws with regard to the time limit for the visitor car parking. NB: Schemes are not permitted to use visitor car spaces for anything other than what they are approved to be i.e. car spaces cannot become a recreational lawn etc.
However, a commercial agreement can be entered into with the local council parking management services to monitor parking within a scheme. If you live in a scheme where visitors or non residents are continually parking illegally on your scheme’s common property then the owners corporation may seek parking management services from their local council. The council would need to agree, and charge a fee.
