Many homeowners ask this because people often mix up modular and manufactured homes. They are not the same thing.
A modular home is built in sections and installed on a permanent foundation, then finished on site. It follows state or local residential code, often the IRC. A manufactured home is built to the federal HUD code. That does not make one "good" and the other "bad," but the financing, appraisal, zoning, and resale process can differ.
If a buyer, agent, or lender incorrectly labels a modular home as manufactured, that can create confusion. Good records help. Keep your plans, permits, inspection sign-offs, foundation details, and final occupancy paperwork.
