California Modular Construction
Factory-built construction
for California.
We deliver volumetric modular apartments, hotels, townhouses, and workforce housing to California projects. Fixed-price contract. 8-month delivery. Up to 40% below conventional cost. HCD and CBC compliant.
Why Modular Works in California
California has the entitlement.
The bottleneck is delivery.
Between SB 35, AB 2011, density bonus, ED1, Builder's Remedy, and the ADU bonus programs, California has unlocked more housing entitlement in the last four years than in the previous twenty. The question is no longer whether a project can be approved. It is whether it can be delivered on a schedule and a budget that pencils.
8 months to occupancy
Site work and factory fabrication run in parallel. Modules arrive 98% complete and crane-set in 1 to 3 weeks. Compared to 18 to 24 months for conventional California construction.
Up to 40% lower delivered cost
Fixed-price contract removes change-order risk. The labor cost gap between Vietnam fabrication and California site-built is the structural advantage modular has in this market.
HCD and CBC compliant
Modules carry HCD insignia where required. Engineered to CBC and ASCE 7 seismic standards for the specific site class. Title 24 documented module-by-module.

We deliver to qualifying projects outside California. If conventional construction in your market is over $200 per SF, modular probably pencils.
Qualification detailsRegulatory Primer
How California regulates modular.
Modular construction is a delivery method, not a regulatory category. Here is how California's existing programs apply to factory-built projects.
HCD modular building program
California's Department of Housing and Community Development regulates factory-built residential modular construction. Our modules carry HCD insignia where required and are inspected to the modular building program standards before they leave the factory.
California Building Code (CBC)
Non-residential and commercial modular projects are governed by the CBC. We engineer to the CBC and ASCE 7 seismic standards for the specific site class and seismic zone of every project.
Title 24 energy compliance
Modules are designed to meet Title 24 for the specific climate zone of the project site. Envelope, glazing, HVAC, and lighting specifications are coordinated with project energy compliance before fabrication.
Prevailing wage and skilled-and-trained workforce
Factory fabrication is performed in Vietnam and is not subject to California prevailing wage. On-site work follows whatever wage rules apply to that project's funding source. Because factory work is roughly 70% of project value, exposure is significantly lower than site-built.
California FAQ
Questions California developers ask.
Is factory-built modular construction legal in California?
+
Yes. California regulates factory-built housing under the Department of Housing and Community Development (HCD) modular building program for residential use, and under the California Building Code (CBC) for non-residential. Both programs are well-established. Our modules carry HCD insignia where required and meet IBC / HUD code for the relevant building type.
How does modular construction interact with California Title 24?
+
Modules are designed and built to meet Title 24 energy efficiency requirements for the specific climate zone of the project site. We coordinate envelope, glazing, HVAC, and lighting specifications with your project's energy compliance before fabrication starts. Title 24 compliance is documented module-by-module and delivered with the project.
Does modular construction trigger California prevailing wage?
+
Factory fabrication happens in Vietnam and is not subject to California prevailing wage law. On-site work (foundation, crane set, utility tie-ins, finishes punch) is performed by your local general contractor and follows whatever wage rules apply to that scope of work and your project's funding source. Because factory fabrication is roughly 70% of total project value, prevailing-wage exposure on a modular project is significantly smaller than on an equivalent site-built project.
How are modules engineered for California seismic conditions?
+
All modules are engineered to the California Building Code (CBC) and ASCE 7 seismic standards for the specific site class and seismic zone of your project. Our engineering team coordinates the connection details, tie-down hardware, and lateral force resisting system with your structural engineer of record before fabrication begins. Seismic engineering is project-specific and documented.
How far is your manufacturing facility from California?
+
Our manufacturing partner is in Vietnam. Modules ship by container vessel to our primary West Coast port of entry, then by truck to the project site. Ocean freight is approximately 18 to 24 days. Total delivery from contract to occupancy is 8 months for a typical multifamily or hospitality project.
Which California regions do you serve?
+
We serve all of California. Our active markets include the Los Angeles Metro, Orange County, San Diego County, the Bay Area, the Inland Empire, the Central Valley, the Central Coast, and Sacramento. Road transport cost varies by region but is included in our fixed-price delivered quote.
Can modular construction qualify for California state housing programs?
+
Yes. SB 35, AB 2011, AB 2097, density bonus, Builder's Remedy, HHAP, No Place Like Home, and other California housing programs are delivery-method-neutral. Any project that qualifies for one of these programs as site-built construction qualifies as factory-built modular construction.
How does modular construction compare on cost in California?
+
Our delivered cost typically runs 25% to 40% below conventional California construction for equivalent multifamily, hotel, townhouse, and single-family projects. The gap is largest in high-labor-cost markets like the Bay Area and smallest in lower-labor-cost markets like the Inland Empire. Our Project Cost Estimator returns a region-specific number for your specific project.
