Commercial Tenant Improvement Contractor in
Los Angeles & Orange County
COMMERCIAL CONSTRUCTION & TENANT IMPROVEMENTS
We here at De Sisto Construction, Inc. (DCI) will continue to do what we do best: tenant improvement projects in the Los Angeles and Orange County areas. Having experience in both corporate structure and managing field labor, we have developed a balance that benefits both clients and workforce. We want the process to be safe and as stress free as possible. But most of all, we want the results to make our clients happy.
The difference in commercial remodel when compared to a home remodel is the scale and timing. Larger projects may involves multiple stories, special scaffolding, extensive exploration into code enforcement requirements, permitting, land use, zoning, and special inspections. This coupled with access to businesses during construction can be tedious and often overwhelming. To help move the process seamlessly, we pride ourselves on efficiency and organization.
Whether you are considering a repair, a face lift, a new configuration, more space or a complete transformation, we are here to provide a complete and comprehensive solution for your needs.
