What Blok Modular Constructors does
Blok Modular Constructors, Inc. is a privately held custom modular construction company founded in 2019 and headquartered in Upland, California. The company designs, manufactures, and installs permanent and relocatable modular buildings, and uniquely combines modular manufacturing with general engineering contractor (GEC) capability to deliver turnkey projects. Its product range spans custom single- and multi-story modular buildings, a standardized pre-owned inventory (24' x 60' units starting at ~$128,000), a floor-plan library covering offices, classrooms, restrooms, lab and industrial buildings, mine-site facilities, guard houses, and container-conversion units in 8' x 20' and 8' x 40' sizes. Underlying technology is factory-controlled off-site construction using Permanent Modular Construction (PMC) lean manufacturing techniques, with MEP, fixtures, and interior finishes pre-installed; the company also emphasizes Building Information Modeling (BIM)-based 3D design visualization.
The company's commercial focus is on U.S. Western-state verticals including commercial/office, K-12 and higher education, healthcare (offices, clinics, imaging, dialysis, outpatient surgery, urgent care), sports & entertainment (locker rooms, training facilities, event venues), industrial/mission-critical (military, mining, petroleum, laboratory), Indian Nation, and general contractor partnerships. Revenue is generated primarily through one-time project fees for design, manufacturing, installation, and site preparation, with sales-led direct engagement (phone, website forms) and a parallel general-contractor partnership channel; licensing is held in California, Nevada, and Arizona. Reference projects cited include a 50,000 SF training facility for a professional sports team and an MRI facility for a university healthcare client, with third-party industry benchmarks cited by the Modular Building Institute indicating 45% schedule reductions and 16% cost savings versus traditional site-built construction. Headcount is 1–10 employees and no outside funding rounds have been disclosed.

Blok Modular Constructors competitors and assessment
Company assessmentBroad incumbents
- McGrath RentCorp: Operates Mobile Modular Plus and other rental/sales modular building services across North America. A direct competitor to BLOK in relocatable modular space, with an established fleet, multiple branches, and recurring rental revenue.
