Prefab homes in Missouri: modular & ADU builders
Modular, ADU, and factory-built companies serving Missouri. Compare listings, then contact builders directly.
In this market
From Kansas City and St. Louis to Springfield, Columbia, and the Ozarks, this page lists factory-built companies, modular, prefab, manufactured, and panelized, not stick-built custom general contractors. Prefably indexes 66 Missouri listings so you can compare ratings and plant or dealer locations before you request a scope.
Basement preferences, frost depth, and rural well/septic installs change the site package as much as the floor plan. Ask for a clear split between factory price and site work, and confirm modular versus HUD-code manufactured labeling for your lender.
Unclaimed listings are public directory records on Prefably. You can open each company profile to see location, ratings when published, phone when available, and the builder website, then contact them directly. We do not sell your inquiry as a lead. If you run the company, claim this listing free to correct details and mark it as claimed after our review.

Context
More about prefab in Missouri
Ground truth for Missouri buyers: the Public Service Commission issues a modular seal that must be affixed to the electrical panel of each new modular unit sold or placed in the state. That seal is not a HUD label. Manufactured homes follow federal HUD construction and installation rules, including licensed installers and approved anchoring. If you searched "custom home builders Missouri," this directory is the factory-built path (Kansas City modular homes included), not a stick-built GC roster. Metro permits in St. Louis and Kansas City run longer than most rural counties.
Open Prefably profiles first, then scan Unclaimed listings. Prefer companies that can show a Missouri modular seal path or HUD install credentials matching the product you want.
Contact builders directly. Prefably does not sell your inquiry as a lead. Pair this hub with our prefab-vs-modular, cost, and financing guides before you deposit.
FAQs
Prefab homes in Missouri
How many prefab and modular builders does Prefably list in Missouri?
As of 2026, Prefably lists 44 factory-built home companies associated with Missouri in this directory (claimed and unclaimed). Counts change as companies claim profiles or we add listings — use the cards on this page for the current shortlist, then contact builders directly.
Does Missouri have statewide modular rules?
Yes. The Public Service Commission issues a modular seal that must be affixed to the electrical panel of each new modular unit sold or placed in the state. That seal is not a HUD label.
Is this a custom home builder directory for Missouri?
No. This hub lists factory-built companies (modular, prefab, manufactured, panelized), including Kansas City modular homes. Stick-built custom GCs are a different search.
How are Missouri permit timelines?
Rural counties often issue residential permits in 1 to 3 weeks. St. Louis and Kansas City metros run longer.
Modular vs manufactured in Missouri?
Manufactured homes follow HUD construction and licensed-installer rules. Modular units follow IRC/IBC with a Missouri modular seal. Lenders treat the paths differently.
How do I find a local modular builder that delivers to my county in Missouri?
Use this directory to shortlist companies that advertise Missouri service, then ask each one to confirm haul routes, crane access, and set crews for your specific county, not just the nearest metro. Rural lots often need a site visit before a quote is real. Open Prefably profiles for ratings and websites, compare at least three written factory-vs-site scopes, and treat “statewide” marketing as a starting claim, not proof. Pair this page with our prefab-vs-modular and cost guides before you deposit.
