Final answer:
Tommy's dad needs to request a variance from the local board to deviate from zoning requirements. A variance, if granted, allows him to use the land in ways not usually permitted under current zoning laws.
Step-by-step explanation:
Tommy's dad needs to ask for a variance when he goes before the local board.
A variance is a request to deviate from current zoning requirements. If granted, it allows a property owner to use land in a way that is ordinarily not permitted by the zoning ordinance.
This might be necessary if the property owner wants to build a structure with dimensions that do not conform to the zoning laws, or if they wish to change the use of their land.
It is important that his request for a variance is well-justified and does not harm the public interest or undermine zoning laws.
