How to use this directory

Buyers usually start with a state page because delivery radius, code path, and local set crews matter more than a national brand name. Each state directory lists modular home builders, prefab and panelized suppliers, ADU specialists, manufactured-home dealers, and tiny-home companies that advertise service in that market.

Open a Prefably profile for ratings when available, phone when listed, and the company website. Unclaimed rows are public directory records builders can claim free. Shortlist three to five companies, ask for a written factory-vs-site scope, and confirm modular (local code) vs manufactured (HUD Code) before you deposit.

Guides: prefab vs modular, which prefab type, modular home cost, modular home financing, prefab ADUs, and FHA modular loans.

Modular home builders

Sections built to local codes, set on a permanent foundation, and finished on site. Often the closest factory-built path to conventional financing and appraisal treatment.

Prefab & panelized suppliers

Wall panels, kits, and packaged systems that still need more on-site assembly than volumetric modular. Useful when you want design flexibility with factory-cut precision.

ADU and tiny home companies

Accessory dwellings, backyard units, and compact primary homes. Density rules, utility connections, and HOA limits matter as much as the factory package.

Manufactured (HUD-code) homes

Built to the federal HUD Code. Lending and foundation requirements can differ from modular. Confirm title and permanent-foundation plans with your lender early.
