As I began reading my blood pressure started rising, then I came to Doug's post. Whew. I want to add that my clients have all gone to reserved parking for all residents. It is working really well. Garden style communities in Dallas area are very short of spaces because occupancy is so high. We use a towing company who issues the stickers and permit numbers and they control it so the manager doesn't have to. And YES you must provide a reserved parking space for valid requests based on disability. And YES, they may require a second reserved spot for their caregiver.
PLEASE before taking action on FH related issues, ask. Rather than make an expensive mistake, ask!!! Doug and I are always willing to help, as are others who train FH.
