HB 791 (Overdorf) revises timeframes in sections 125.022 and 166.033, Florida Statutes, for counties and municipalities to process applications for approvals of development permits or development orders and requires these governmental entities to issue certain refunds for failure to meet the timeframes.  The bill requires counties and municipalities to specify in writing the information that must be submitted in an application for zoning approval, rezoning approval, subdivision approval, certification, special exception, or variance.  It requires counties and municipalities to confirm receipt of an application for development permit or order within five days.  The bill specifies the statutory timeframes shall restart if an application makes a substantive change to an application, which is defined as a change of 15 percent or more in the proposed density, intensity, or square footage of a parcel.  The bill requires counties and municipalities to issue refunds ranging from 10 to 100 percent of the application fee for failure to meet the statutory timeframes for determining whether an application is complete or requires additional information and for taking final action on an application.
