I would like to pass on a little bit of useful information for anybody thinking of converting their permit over to owner-builder. 1 - You will not be able to sell the property for a minimum of 365 days from the date of issuing of the CO. 2 - The property must be for the owner's own use and occupancy and not for sale or lease which means you will not be able to rent it out. 3 - The owner-builder must ensure that all employees working on the project have the required licenses.4 - The owner-builder must provide worker's compensation as required by Florida law.5 - To apply for the owner builder permit, you must physical visit the building department.There are others requirements and conditions, however these are the main items.
