Your assumption about outside is correct, probably violates a deed restriction. Yet, I've accidentally discovered several where they are stored against a side wall that isn't very visible from the street.
This
vertical rack for two kayaks fits between 2 car bays, with ~just~ enough room to open car doors without banging into the boats.
We too brought along 2 kayaks. Haven't used them because one of is leery of gators in every watering hole around.
GOOD LUCK with your move!
