Bill > HB0570

This bill modifies how impact fees are calculated for new single-family homes by specifying that the number of plumbing fixtures shown in the building plans must be used to determine the development activity's proportionate share of the fee. Impact fees are charges imposed by local governments or private entities on new developments to help pay for the costs of public facilities and services, such as roads, water, and sewer systems, that are needed to serve the new development. The bill also clarifies that when calculating these fees, entities may include costs like construction contracts, land acquisition, planning, engineering, debt service for financing improvements, and overhead expenses, and they must base these calculations on realistic, disclosed estimates.
