Good morning, Catie:
We always recommend an independent inspection for new construction. We tell the builder this at the pre-construction meeting so that they know up front. A good builder will have a construction supervisor and government code/building inspector reviewing the construction and will welcome another set of eyes on the build before closing things in. Inexperienced or independent builders will often be more careful knowing someone besides the code/building inspector is reviewing.
Pre-drywall inspections have found improperly flashed windows and doors, warped wall studs, broken structural trusses, missing metal clips, missed fireproofing, plumbing in the wrong place, overly long HVAC runs, and other things that were relatively easily corrected before things were covered up. If they were ever discovered later, they could be expensive to find and correct, make the home difficult to sell, or even be the basis for denial of an insurance claim.
We recommend clients get a Buyer Agent Advocate for New Home Construction (see link) and a home inspector experienced with inspecting new construction. Often, we negotiate for the Seller to pay for your independent inspection.
