The Long Island United Solar Permitting Initiative, a collaborative effort of the Suffolk County Planning Commission, Nassau County Planning Commission and the Long Island Power Authority (LIPA), developed the model LIPA Fast-Track Permit Application to help Long Island municipalities streamline and standardize the building permit application process for “standard” installations of grid-tied PV or Residential Solar Hot Water (RSHW) systems. Babylon Town Code Ch. 89, Art. X established a solar energy system fast-track permit process modeled after the LIPA template to simplify and accelerate the installation of standard solar energy systems on one-and-two family residences. Babylon provides a Fast Track Building Permit Application Checklist to guide applicants.
