Revise impact fee laws

This bill updates Montana's state laws governing impact fees that local governments charge to developers to fund public infrastructure improvements. It directly affects cities, towns, counties, and other local governments that collect these fees from new construction projects. The legislation clarifies definitions for terms like "impact fee," "capital improvements," and "public facilities," while removing the ability to include administrative costs in the fee amount. It also requires local governments to create detailed service area reports that document how fees are calculated and how they will fund specific infrastructure needs. Additionally, the bill limits impact fee increases to no more than the rate of inflation and mandates that collected fees be allocated to construction projects within a five-year budget plan.
