If you are evaluating these providers for a specific development, would you like to share:

• The target geography or location of the project?
• Whether you need low-rise wood frame, mid-rise steel/hybrid volumetric modules, or panelized components?

I can help narrow down which provider matches your structural requirements and scale.

If you mean the U.S. multifamily market, the leading providers depend heavily on what you mean by “modular components”: complete volumetric apartment modules, bathroom/kitchen pods, MEP modules, wall/panel systems, or hybrid systems. The market is still fragmented rather than dominated by a single supplier.Modular Building Institute+1

Major providers to know

Current industry research specifically identifies SurePods, Bathsystem USA, BLOX, Castle Modular, B&T Manufacturing, Guerdon, VBC, Z Modular, Champion Modular, VESTA, MODLOGIQ and others among the significant North American prefabricated-module suppliers.Mordor Intelligence

Particularly interesting for multifamily

SurePods is probably the most directly comparable company if you're looking at bathroom pods as a component strategy. It says its multi-living work includes apartments, student housing and assisted living, and its model integrates BIM, factory production and installation.SurePods

surepods.com

For whole apartment modules, Guerdon, VBC and Autovol are more relevant. Guerdon, for example, produces integrated volumetric modules containing structural elements, finishes and MEP systems.Grand View Research

For a componentized approach rather than entire volumetric units, Dorothy Homes is interesting: its system combines prefabricated bathrooms and MEP walls and is explicitly designed to scale to apartment buildings.Dorothy Homes+1

How I'd segment the market

If you're researching this for investment, procurement, or a new multifamily development, I'd break the supplier landscape into four categories:

• Bathroom/kitchen/utility pods: SurePods, Bathsystem USA, Durapods, ModPod, Dorothy Homes
• Complete volumetric apartment modules: Guerdon, Autovol, VBC, Champion Modular, MODLOGIQ
• Panelized/hybrid systems: VBC and other panelized-system manufacturers
• Broader prefabrication: wall panels, MEP racks/risers, structural/envelope assemblies and other components from companies such as Skanska's prefabrication operation

The distinction matters because pod suppliers can be integrated into a conventional site-built multifamily project, whereas volumetric suppliers can potentially industrialize much more of the building. Skanska, for example, describes its prefabrication capabilities across bathroom pods, MEP risers, wall systems, structural framing and volumetric modules.Skanska

If you tell me whether you're interested in (1) bathroom/MEP pods, (2) complete apartment modules, or (3) structural/wall panels, I can narrow this to the 10–15 most relevant North American companies and compare their manufacturing locations, capacity, typical project size, pricing model, and notable multifamily projects.

SurePods is probably the most directly comparable company if you're looking at bathroom pods as a component strategy. It says its multi-living work includes apartments, student housing and assisted living, and its model integrates BIM, factory production and installation.surepods.com

If you are looking into a specific region or need a particular type of structure (e.g., wood-frame vs. steel-frame volumetric modules or affordable housing vs. high-rise luxury ), let me know and I can narrow down the best partners or suppliers for your needs.

If you mean U.S./North American suppliers that can provide factory-built modules or major prefabricated components for multifamily apartments, the market is fairly concentrated. The strongest names today include:

The standouts

FullStack Modular is one of the strongest choices if you're talking about mid- and high-rise apartment construction. Its steel modular system is designed for urban multifamily projects and can incorporate interiors, MEP, finishes and other building elements in the factory. Industry research currently identifies FullStack among North America's leading modular players.MarketsandMarkets

Guerdon is another major established player, particularly for larger multifamily, workforce, student and senior-living projects. It provides a fairly comprehensive off-site-to-site solution rather than simply selling individual components.MarketsandMarkets

VBC (Volumetric Building Companies) is particularly interesting for developers looking for industrialized production at scale. It operates U.S. factories in California and Pennsylvania and explicitly targets multifamily, hospitality and student housing. Its Tracy factory, for example, is designed to produce up to 25,000 sq. ft. of housing per week on a single shift.Volumetric Building Companies+1

Z Modular, a Zekelman Industries company, is notable because it combines steel manufacturing expertise with modular apartment development. It reports 4,000+ apartment units in operation and four manufacturing facilities capable of producing more than 1 million finished sq. ft. annually each on a single shift.Zekelman Industries

Factory_OS is particularly relevant if your interest is affordable/workforce housing and highly standardized apartment designs. Its model is centered on manufacturing most of the building off-site and assembling it at the project site.Crunchbase

An important distinction: "modular components" vs. complete modules

If you're looking for components rather than entire volumetric apartment modules, I'd broaden the competitive set. There is a growing market for factory-built:

• Bathroom pods
• Kitchen pods
• MEP racks
• Utility/core assemblies
• Wall panels
• Floor/ceiling cassettes
• Structural steel or light-gauge steel assemblies
• Prefinished façade assemblies

For example, Resia Manufacturing specifically manufactures prefabricated bathroom and kitchen components for industry partners, rather than limiting its production to complete volumetric buildings. Modular Building Institute Greystar's Modern Living Solutions likewise operates a factory in Pennsylvania focused on producing apartment modules for its developments.Greystar

My shortlist by business model

If you're evaluating these companies as potential suppliers/partners, I'd divide them this way:

• Complete volumetric apartment modules: FullStack, Guerdon, VBC, Z Modular, RISE
• Affordable/workforce housing: Factory_OS, VBC, Z Modular, Resia
• High-rise/urban multifamily: FullStack, Guerdon, Z Modular
• Bathroom/kitchen/component strategy: Resia, Greystar/Modern Living Solutions
• Highly scalable factory platform: VBC, Z Modular
• Broader international modular platform: Vantem

The overall market is significant: the Modular Building Institute says multifamily was the largest segment of U.S. permanent modular construction in 2025, at approximately $6.8 billion, and projects roughly 8.6% annual growth through 2030.Modular Building Institute

If you're asking this from an investment, sourcing, or competitive-intelligence perspective, I can also build a top-15 provider comparison with factory locations, annual capacity, module type, typical building height, geographic coverage, ownership/funding, notable multifamily projects, and estimated scale.

Factory_OS is particularly relevant if your interest is affordable/workforce housing and highly standardized apartment designs. Its model is centered on manufacturing most of the building off-site and assembling it at the project site.

An important distinction: "modular components" vs. complete modules

If by “modular construction components” you mean factory-built modules and major prefabricated assemblies used in U.S. multifamily projects—rather than manufactured homes—the leading providers fall into a few distinct groups.

The market is substantial: the Modular Building Institute reports that multifamily was the largest permanent-modular segment in the U.S. in 2025, at about $6.8B, with projected growth of roughly 8.6% CAGR through 2030.Modular Building Institute

Leading volumetric modular providers

Component/pod specialists

If you're looking specifically for components that can be incorporated into a conventional multifamily building, rather than an entire modular building, the competitive landscape is different:

• SurePods — One of the largest U.S. bathroom-pod suppliers. Industry research identifies it as the North American market leader, with particularly significant multifamily, hospitality and healthcare exposure.Global Market Insights Inc.
• Bathsystem USA — Supplies prefabricated bathroom and kitchen pods, manufactured in the U.S., with multifamily among its target sectors.BathsystemUSA
• Durapods — Steel-framed, finished bathroom pods with an emphasis on BIM coordination and factory QA/QC.Global Market Insights Inc.
• NeoPod Systems — Bathroom and kitchen modules/pods spanning multifamily, student housing, hospitality and other applications.Global Market Insights Inc.

Panelized / structural systems

There is also a growing middle ground between traditional construction and full volumetric modular:

• MODLOGIQ — Offers cold-formed-steel wall, floor and roof panels, ranging from framing-only to wired, plumbed, drywalled and windowed assemblies.MODLOGIQ
• Champion Homes — One of the largest factory-built housing manufacturers in North America, with a very large manufacturing footprint and modular capabilities, although its business is broader than multifamily construction.DataNext Insights

My shortlist for a multifamily developer

If the objective is to identify companies worth putting through an RFP/prequalification process, I'd start with:

One important distinction: “leading” depends heavily on what you're procuring. A developer looking for a complete modular apartment building should evaluate VBC, Factory_OS, Guerdon, FullStack and similar firms; a developer pursuing a hybrid conventional/modular strategy may get more value from pod suppliers such as SurePods or Bathsystem, or panelized suppliers such as MODLOGIQ.

If you're evaluating this as a business opportunity/supply chain, I can also rank the top 15 providers by estimated scale, manufacturing capacity, geography, product type, ownership, and multifamily project experience.

If you mean U.S./North American multifamily, the market is best viewed by component type rather than as one homogeneous “modular construction” category. Multifamily was the largest permanent modular segment in the U.S. in 2025, at about $6.8B, according to the Modular Building Institute.Modular Building Institute

Leading providers to consider

How I'd segment the competitive landscape

1. Bathroom pods — probably the most mature component category. SurePods is particularly prominent, with industry research identifying it as the North American market leader. Bathsystem USA, B&T Manufacturing, Durapods, ModPod and others form the next tier.Global Market Insights Inc.+1

2. Structural/panelized systems. Prescient is an important name here, particularly for multifamily buildings where the objective is to industrialize the framing and enclosure process rather than manufacture complete apartments. Its technology combines digital design with factory-produced steel framing assemblies.Building Design + Construction

3. Complete volumetric modules. Autovol, Factory_OS and Guerdon are more vertically integrated: rather than supplying one component, they can manufacture substantial portions of an apartment module off-site. This is attractive when developers want maximum schedule compression and reduced site labor.Global Market Insights Inc.+1

4. Integrated industrialized housing. Veev represents the more vertically integrated end of the spectrum, combining proprietary wall systems, factory manufacturing and residential development/building capabilities.Veev, by Lennar

My shortlist for a multifamily developer

If the goal is sourcing components rather than hiring a complete modular GC, I'd start with:

1. SurePods — bathroom pods / repeatable wet-area packages
2. Bathsystem USA — bathroom pods
3. Prescient — structural framing/wall systems
4. B&T Manufacturing — bathroom pods
5. Autovol — larger volumetric modules
6. Guerdon — complete modular building modules
7. Factory_OS — complete multifamily modules

The important distinction is that SurePods/Bathsystem/B&T are component specialists, while Autovol/Guerdon/Factory_OS are closer to off-site building manufacturers. That's a meaningful difference when you're evaluating procurement, engineering responsibility, transportation, installation and project risk.

If you're looking at this from an investment, procurement, or competitive-landscape perspective, I can also build a more useful table of 20–30 North American suppliers, including product type, manufacturing location, annual capacity, typical project size, geographic coverage, ownership/funding, notable multifamily projects, and estimated scale.
