What is the TOSA Prep Modular Building in Salt Lake City and How Big Is It?

In the heart of Salt Lake City’s historic district, a new approach to workforce housing is taking shape. The TOSA Prep modular building project showcases not only an innovative construction method but also a strategic response to critical recruiting constraints faced by local employers. This blog post explores what the TOSA Prep building is, its size and layout, and how companies like Irontown Modular, The Other Side Village, and My Cozy Outdoors are playing pivotal roles in advancing modular construction in the region.

Understanding TOSA Prep: A Modular Workforce Housing Solution

TOSA Prep is a modular multifamily residence located within the historic district Salt Lake City, designed specifically to address the growing need for quality, affordable workforce housing. The project provides 32 two-bedroom units, totaling 33,860 square feet of living space. This kind of development aims to attract and retain workers in vital sectors such as education, healthcare, and tech, by alleviating one of the main recruitment barriers: housing availability.

Workforce Housing as a Recruiting Constraint

Recruiters and HR professionals nationwide increasingly report housing scarcity as a significant bottleneck when hiring skilled workers. Salt Lake City is no exception. The city's expanding economy, with its growing tech scene and health services, has boosted demand for workforce housing that remains affordable and close to transit and job centers.

Projects like the TOSA Prep modular building directly respond to these challenges by streamlining construction and reducing costs. Modular building techniques enable faster delivery, helping employers and municipalities realize affordable housing options quickly—all critical to maintaining a competitive edge in recruitment.

Modular vs Manufactured: Definitions and Code Differences

The TOSA Prep project utilizes modular construction, a method often confused with manufactured housing but critically different in how it’s regulated and built.

Modular buildings are constructed off-site in factory-controlled environments in sections or "modules." These modules meet local building codes for permanent housing—such as the International Residential Code (IRC) or International Building Code (IBC)—and are assembled on-site to form a complete structure indistinguishable from traditional stick-built buildings.
Manufactured homes (formerly "mobile homes") are constructed entirely off-site according to the HUD Code, a federal standard for factory-built housing. These units are typically transportable and often sited permanently within manufactured home communities.

For a workforce housing project in the Salt Lake City historic district, modular construction is the preferable route—not only for meeting local building codes but also for integrating within historic neighborhoods without compromising zoning or aesthetic standards.

Permitting Workflow and Inspections for Modular Projects

Permitting modular buildings like TOSA Prep requires coordination across multiple stages—both factory-controlled and on-site—to comply with city and state regulations.

Plan Submission: Detailed modular plans must be submitted to Salt Lake City’s building department for review, confirming compliance with building codes and historic district guidelines.
Factory Inspections: During module fabrication, independent inspectors verify that each module meets applicable construction standards.
Transport and Assembly: Modules are transported to the site, where inspections ensure connection integrity, proper foundation adherence, and utility hookups.
Final City Inspections: After assembly, city building inspectors conduct thorough walkthroughs to issue occupancy permits.

This layered process demands close collaboration between the modular production company, local plan reviewers, and on-site contractors. In the case of TOSA Prep, companies such as Irontown Modular work directly with city officials to smooth these workflows.

Schedule Compression Through Parallel Factory and Site Work

One of modular construction’s greatest advantages—well exploited in the TOSA Prep project—is its ability to compress project timelines by allowing parallel workstreams.

Factory Work: While site excavation, foundations, and onsite utility infrastructure are being prepared, modules are simultaneously built in a factory environment.
On-Site Work: Foundations and site-related installations occur uninterrupted, eliminating the sequential delays common in traditional stick-built projects.

This parallel workflow leads to significant reductions in overall construction https://www.re-thinkingthefuture.com/architectural-styles/manufactured-homes-for-employee-housing-what-modular-construction-actually-delivers/ schedules. For a 33,860 square feet project with 32 two-bedroom units like TOSA Prep, these time savings translate directly into quicker occupancy and earlier availability of workforce housing units.

Industry Partnerships Driving the TOSA Prep Project

The success of a modular project in sensitive areas such as Salt Lake City’s historic district depends on technical expertise and community engagement. Three key players in this ecosystem are:

Irontown Modular: A local modular production firm specializing in multifamily housing. Irontown is instrumental in manufacturing the TOSA Prep modules with precision, ensuring compliance with city codes and facilitating rapid assembly.
The Other Side Village: This organization advocates for creative housing solutions and supports community outreach to integrate modular housing acceptably within historic districts.
My Cozy Outdoors: A company focused on outdoor living enhancements for multifamily and modular developments, providing complementary site solutions such as landscaping and amenity spaces for projects like TOSA Prep.
