Construction Companies in Rancho Cucamonga, CA

Verify their general contractor license

GC licenses are issued by the state. Verify the license is active, check for disciplinary history, and confirm they're bonded and insured for the project value.

Review the contract carefully

Construction contracts should specify: start and completion dates, payment schedule tied to milestones, allowances for materials, change order process, and lien waiver requirements.

Understand the change order process

Changes during construction are inevitable. Get clarity on how change orders are priced and approved before work starts — unsigned verbal change orders are the leading cause of construction disputes.

Confirm permit responsibility

The GC should pull all required permits. Building, electrical, plumbing, and mechanical permits may all be required. Unpermitted work creates serious problems at resale.

Request lien waivers

Conditional and unconditional lien waivers from the GC and all subcontractors at each payment milestone protect you from mechanics liens if the GC doesn't pay their subs.
