Keep in mind that most condo corporations/declarations require you to OWN a dwelling in the building before you are able to also own a parking space in the building. Therefore renters usually do not form part of your buyer demand for a parking space. Also note, that some condo corporations/declarations may also have rules against any signage - and more commonly, a rule against storing ANYTHING in a parking space other than a vehicle. But I personally like the sign, great idea!
