MS Housing Infrastructure Support Program; create to provide grants and low-interest loans for certain public infrastructure improvements.

This bill creates the Mississippi Housing Infrastructure Support Program, providing grants and low-interest loans to counties, municipalities, and public utility authorities for public infrastructure (like water systems, roads, and utility extensions) directly enabling housing development. It requires local governments to contribute at least 25% of project costs through matching funds and prohibits enforcing lot or home size restrictions on funded projects. Funds cannot cover housing construction, rental subsidies, or operating costs, with grants capped at $5 million per project and loans limited to 2% interest over 20 years.
