Your contractor will try to obtain permits for the work that was done before you took possession of the house and then you will discover that there are no permits for the improvements you want to change or replace. There are many types of works and improvements that can be done in a home and that require permits, and any time these works are done without a permit, even if the results were correct, it is considered work not allowed. There are many housing changes in Florida that must be made with a permit, so if changes have been made to the housing in question, it must be assumed that a permit should have been issued to carry out the work. If you are in a situation where you are a homeowner in Florida that has had unauthorized improvements made, you should work with an experienced attorney to obtain compensation for the cost of permits that were never issued.
This is never the recommended procedure when you need to make an improvement to a property and you'll want to consider this in the future as well if you think you simply want to skip paying for permits for an improvement. If you have purchased a home with improvements that are not allowed, you need to know what your options are if you are going to sell it later or what should be done if you are trying to improve your home to meet the rules.
