Development Fees and Improvement Requirements State law limits fees charged for development permit processing to the reasonable cost of providing the service for which the fee is charged. Various fees and assessments are charged by the City and other public agencies to cover the costs of processing permit applications and providing services and facilities such as schools, parks and infrastructure. Almost all of these fees are assessed through a pro rata share system, based on the magnitude of the project's impact or on the extent of the benefit that will be derived. Table IV-6 provides a list of fees the City of Laguna Niguel charges for new, standard residential development. The rates charged by the City are inclusive and based on standardized unit sizes. Development fees will vary from project to project depending on the specific characteristics.
