Frequently Asked Questions
What's the difference between commercial and residential general contractors?
Commercial contractors build offices, retail, warehouses, and multi-family properties following IBC codes. Residential contractors build single-family homes and remodels following IRC codes.

Can a residential contractor do commercial work in Houston?

Most residential contractors lack the experience with IBC codes, ADA compliance, and fire safety systems required for commercial projects.
Do commercial contractors cost more than residential in Houston?

Commercial projects also require specialized equipment, fire suppression systems, and ADA-compliant features.
