Time to have an “audit’ of cars. The EC should send round a circular telling people that you are trying to establish which cars belong in the building and which are non-resident or abandoned cars. You want them to give you their registration details and unit numbers to make sure they are not identified wrongly as abandoned or “rogue” parkers who are non- residents.
Explain in the note that following the audit, cars that are illegally parked in visitors parking, on common property or another owner’s car space and are not on the register will be removed from the building so they can be dealt with by being declared abandoned and towed away by the local council.
In the case of cars that are on the register but wrongly parked, information will be provided about where and when they can park legally. You could also go a bit further and ask owners who have car spaces that are empty and wish to rent them (to residents only) should let the EC know and the information will be passed to people who need extra parking.
In the meantime, you could pass a by-law requiring all residents – owners and tenants – to register the car registration numbers and their unit numbers with the strata manager and EC within, say, 14 days of moving into the building or acquiring a new car or, indeed, when a parking audit is conducted.
We did a vehicle audit in a building because we suspected residents were renting unused car spaces that they didn’t own to their friends and people who worked nearby. We left the audit notices on every car and in every letterbox. Over one weekend, about 20 cars disappeared from the car park, never to be seen again
FYI: Removing illegally parked cars is not strictly legal in itself but it’s very effective, if THIS STORY is anything to go by.
