IMPACT FEES – Amends existing law to revise provisions regarding minimum standards and requirements for development impact fees ordinances.

H 626 revises Idaho's rules for local governments imposing development impact fees on new construction projects. It requires fees to be calculated based on actual or estimated infrastructure costs (like roads or water systems) directly tied to new development, not exceeding a project's fair share. The bill mandates clear written explanations for fee calculations, allows developers to request individual assessments using supporting data, and requires fees to fund specific improvements within the project's service area. It also permits exemptions for affordable housing projects if they're in the local comprehensive plan and funded by other sources. The changes primarily affect local governments creating fee ordinances and developers paying these fees.
