Deep Creek is not officially Punta Gorda Isles. It has a Punta Gorda mailing address but is physically located in Port Charlotte. Here are the links to the two different homeowner associations in Deep Creek. You can read their rules and regulations online.

You can go to this site to see the ordinances for Punta Gorda Isles to read the restrictions on fences.

The non-deed restricted areas in Port Charlotte and Punta Gorda will allow you to have a fence any size you want. I would be happy to send you some listings if you could provide your search criteria.
