The following is a copy/paste from the township description page. See the link for the full text.
Within the Township's borders are the unincorporated developments of South Seaside Park, Bayville, Pinewald, Manitou Park and Pelican Island on Barnegat Bay.
One example of a need for a variance is if the placement of the garage would violate a setback requirement. All structures must be "x" feet from the front, and "y" feet from the side, etc. Suppose where you want to place your garage, would place it 1 foot short of the minimum setback requirement. You would then need a variance. This is only one example.
The town can look up your lot and block number by your address. You will need to reference the zoning map for your lot and block. Towns are used to helping homeowners with this, just ask. This will provide you the guidelines and give you the starting point of your research and due diligence.
Don't begin any work, or put up deposits with contractors until you know you have proper permits.
It shouldn't be difficult, you just want to follow the rules. Towns want you to follow the rules and will help you gather the proper info.
