Re: Fobs being used by two non owners and non residents
Can’t everyone’s fob be reprogrammed? Everyone but the two so-and-sos with a useless fob, that is.
Doing that will leave them in the cold.
Re: Habitual illegal car parkers
I am unsure of all your options, but two things come to my mind:
1. Fine the wrong doers
Ask your friendly local council to issue fines to the trespasser (see https://www.nsw.gov.au/housing-and-construction/strata/living/parking). It would help if you have already taken photos of the illegally parked cars;
or
2. Install hurdles for the wrong doers
That would involve, in each visitor car space, installing a parking bollard, IMHO the “fold down” type makes sense.
These require a key in order to fold down. Installed in each car space, it will prevent anyone parking there who has not folded down the bollard. That is, any illegal parkers.
Owners/residents should be given a key to the bollards.
6 visitor spaces means 6 bollards. Ideally they are keyed the same, every owner/resident will be able to access all visitor spaces in order to allow a visitor to park.
The only downside is that a lot owner would have to leave his/her apartment in order to allow a visitor to park. Not really a hassle when you consider the upside: a car space which if not available to a particular visitor, at least is being used by another legitimate visitor(s).
A quick look online, granted I looked at just one website, reveals a cost from $95 per bollard plus (unspecified $ for) installation.
