Commercial Construction

New Commercial Construction for St. Clair County, IL.

Otten Contracting provides commercial construction services for businesses, developers, and organizations throughout Marissa, IL, St. Clair County, Monroe County, and the greater Southern Illinois Metro-East region. With over 35 years of experience, our team delivers turnkey building solutions that balance functionality, efficiency, and long-term value.

We partner with clients to construct a wide range of commercial facilities, including:
– Office buildings designed for productivity and modern workplace needs
– Retail spaces that maximize visibility, layout, and customer experience
– Warehouses and light industrial facilities built for efficiency and safety
– Municipal and institutional projects, tailored to community requirements

As a licensed and insured contractor, we manage every stage of the project — from design coordination and site preparation to construction management and final delivery. Our team understands the unique challenges of budget control, tight schedules, and compliance requirements, ensuring your project is completed on time and within budget.

Unlike residential construction, commercial builds demand scalability, compliance expertise, and long-term planning. Otten Contracting delivers results that help businesses grow, communities thrive, and investments stand the test of time. With a reputation for quality craftsmanship, professional execution, and 24/7 availability, we remain a trusted partner for commercial property owners and developers across Southern Illinois.
