Irontown Modular is a modular construction company specializing in prefabricated Accessory Dwelling Units (ADUs) designed to simplify and accelerate the building process. Headquartered in Spanish Fork, Utah, the company serves homeowners—particularly across Southern California—who are looking to add functional, high-quality living space to their properties without the delays and complexity of traditional construction.

At its core, Irontown Modular focuses on delivering a streamlined, end-to-end building experience. From the initial site evaluation and budgeting to permitting, factory fabrication, on-site installation, and final inspection, every phase of the project is managed under one roof. This integrated approach reduces uncertainty, improves efficiency, and ensures a more predictable outcome for homeowners.

What sets Irontown Modular apart is its use of off-site, factory-built construction. By building ADUs in a controlled environment, the company is able to maintain consistent quality while significantly reducing build times. Once the unit is complete, on-site installation can often be completed in as little as a day, minimizing disruption to the property and surrounding area.

Irontown Modular offers a range of detached prefab ADUs and park model units, with flexible floor plans and customization options. Whether the goal is to create a backyard cottage, in-law suite, guest house, or income-generating rental unit, their designs are tailored to fit both the property and the homeowner’s vision.

With a focus on transparency, efficiency, and practical design, Irontown Modular helps property owners turn underutilized space into valuable living areas—making ADU construction more accessible, predictable, and aligned with modern housing needs.
