The United States has a large factory-built housing market. Buyers can find everything from affordable factory-built homes to custom modular houses, modern prefab homes and regional modular builders.
A modular home is built in factory-made sections, called modules. These modules are transported to the site and placed on a prepared foundation. This is different from a manufactured home, which is a separate US housing category built under the federal HUD Code.
This difference matters. Some companies build both manufactured and modular homes. Others focus mainly on true modular homes. Before choosing a supplier, buyers should confirm exactly what type of home they are buying and whether it is allowed on their land.
This article lists 10 notable modular home manufacturers and providers in the USA. It is not a strict ranking from best to worst. The right company depends on your state, land, budget, design needs, delivery area and local building rules.
What to know before buying a modular home in the USA
Before comparing modular home manufacturers, check your land.
Rules can vary by state, county, city and local zoning area. A modular home may be allowed in one location but require a different approval process in another. Local rules can affect the foundation, building size, roof pitch, utility connections, setbacks and final inspections.
You should also check whether the company serves your area. Many US modular home manufacturers work through regional dealers, builders or approved builder networks. A company may be strong in one part of the country but not available in another.
The most important question is not only “Who builds the best modular home?” The better question is: “Which manufacturer can deliver the right home for my land, local code, budget and project scope?”
10 modular home manufacturers to compare
1. Clayton Homes
Clayton Homes is one of the largest factory-built housing companies in the United States. Its home building group includes many production facilities and offers different types of off-site built homes, including modular homes.
Clayton can be relevant for buyers who want a large company, many floor plans and broad regional availability. Because Clayton also sells manufactured homes, buyers should be careful to confirm the exact product type.
If you want a modular home, ask whether the selected model is built to modular code for your state and local area, not only whether it is “factory-built.”
2. Champion Homes
Champion Homes is another major US factory-built housing company. It builds manufactured homes, modular homes, ADUs, park-model RVs and modular buildings.
Champion is useful to compare because it has a large manufacturing network and many brands. This can give buyers access to different home styles and regional options.
As with Clayton, buyers should confirm whether the specific home is modular or manufactured. The dealer, local builder and installation team can also have a major impact on the final result.
3. Cavco Homes
Cavco is one of the largest factory-built home producers in the USA. The company builds manufactured homes, modular homes, park model RVs and other factory-built structures through a family of brands.
Cavco may be a good option for buyers who want a broad range of home styles and regional availability. It is especially relevant because some Cavco brands are well known in modular construction, including former Nationwide Homes operations.
Before choosing, ask which Cavco factory or brand will build the home, what code the home follows, and who handles foundation, delivery and installation.
4. Ritz-Craft
Ritz-Craft is a major modular home manufacturer and describes itself as the largest family-owned and operated modular home manufacturer in the United States.
The company focuses clearly on modular construction, which makes it easier for buyers who do not want to confuse modular homes with manufactured homes.
Ritz-Craft may be suitable for buyers who want a custom or semi-custom modular home through a builder network. It is worth comparing if you are looking for a permanent home rather than a mobile or HUD-code manufactured home.
5. Commodore Homes
Commodore Homes builds manufactured and modular housing under several brand names, including regional brands across the Northeast, Midwest and Mid-Atlantic.
This makes Commodore relevant for buyers in those areas who want to compare modular home options from an established factory-built housing company.
Because Commodore works through multiple brands and regions, buyers should check the exact factory, model, builder relationship and delivery area before making a decision.
6. Westchester Modular Homes
Westchester Modular Homes is a custom modular home manufacturer based in Wingdale, New York. The company has been designing and building modular homes since 1986.
It is especially relevant for buyers in the Northeast, including New York, New Jersey, Connecticut, Massachusetts and nearby states.
Westchester Modular can be a good option for buyers who want a custom modular home from a regional specialist rather than a national manufactured-home group.
7. Excel Homes
Excel Homes is a modular home company with a long history in custom modular housing. It has been designing and building custom modular homes since 1984.
Excel may be useful for buyers who want design flexibility but still want the structure and speed of modular construction. It works through a modular process where much of the home is built in a controlled factory environment.
This company is worth comparing if you want a more traditional house shape with custom options, rather than a small modern prefab cabin.
8. Stratford Homes
Stratford Homes is a custom modular manufacturer serving parts of the northern and western United States. The company builds single-family homes, multi-family homes and commercial projects.
Stratford may be especially relevant for buyers in states such as Wisconsin, Minnesota, Montana, Idaho, Oregon, Washington and nearby regions, depending on service availability.
It is a good example of a regional modular manufacturer. For many buyers, a strong regional company can be more practical than a national brand because it may better understand local delivery, climate and builder relationships.
9. Method Homes
Method Homes is a Washington-based custom modular construction company. It focuses on modern prefab homes, custom residential projects and commercial structures.
Method is more design-led than many large factory-built housing companies. It may be a better fit for buyers who want a custom modern home, cabin, retreat house or architect-designed modular project.
This type of modular home usually requires more planning, design work and budget clarity than choosing a standard catalogue model. Buyers should ask carefully about design fees, site work, transport and installation scope.
10. Dvele
Dvele builds modern prefab modular homes with a focus on high-performance systems, energy efficiency and smart home features. Its homes are built in modular sections and shipped to the building site by truck.
Dvele may be interesting for buyers who want a premium modern modular home, not only a basic factory-built house. It can be especially relevant for people comparing energy-focused homes and repeatable modern designs.
As with other advanced prefab systems, buyers should check service area, local code approval, foundation requirements, utilities and the full installed project cost.
Large groups vs custom modular builders
The US modular market has two different types of companies.
Large factory-built housing groups, such as Clayton, Champion and Cavco, can offer broad production capacity, many floor plans and regional dealer networks. These companies may be useful if you want many options and established scale.
Custom modular builders, such as Method Homes, Westchester Modular, Excel, Stratford and Dvele, may be better for buyers who want more design control or a specific regional building process.
Neither type is automatically better. The right choice depends on your project.
If you want a simpler and more affordable route, a large producer may be worth checking first. If you want a custom home on a special plot, a regional or design-led modular manufacturer may fit better.
How to compare modular home manufacturers
Do not compare only photos or floor plans.
Ask each company what type of home it builds. Is it modular, manufactured, panelized, park model, tiny home or another category?
Then ask what is included in the price. Some offers may include only the factory-built modules. Others may include transport, setting, interior finish, technical systems or builder coordination.
Also ask what is excluded. Foundations, permits, utility connections, septic systems, driveways, crane work, landscaping and local site preparation are often separate.
A modular home can still require a lot of local work. The factory is only one part of the final project.
Questions buyers should ask before signing
Before paying a deposit, ask clear questions.
Can this home be built as a modular home for my state and local code?
Do you serve my location?
Who is the local builder or dealer?
Who handles permits, foundation, utilities and installation?
What is included in the quoted price?
What is excluded?
Can I see completed homes similar to mine?
Who is responsible if something is damaged during transport or installation?
Can I visit a model home, factory or completed project?
These questions help buyers avoid confusion. In the US, the difference between modular and manufactured homes can affect zoning, financing, inspections and long-term value.
How PrefabFind helps buyers
PrefabFind helps buyers compare prefab manufacturers and modular home manufacturers in one place.

With PrefabFind, buyers can compare companies by country, building type and project category before contacting suppliers directly.
Conclusion
The USA has many strong modular home manufacturers and factory-built housing companies. Clayton Homes, Champion Homes, Cavco Homes, Ritz-Craft, Commodore Homes, Westchester Modular Homes, Excel Homes, Stratford Homes, Method Homes and Dvele are all worth knowing when researching modular homes.
There is no single best modular home manufacturer for every buyer. Some companies are stronger for affordability and scale. Some are better for custom homes. Some are more regional. Others focus on modern architecture or energy performance.
The safest approach is simple: check your land first, confirm local rules, compare several modular home manufacturers, and make sure the full project scope is written clearly before you pay.
