GC says we can start hanging Monday to make the schedule; the electrical rough, plumbing rough, and insulation inspections are all scheduled for Wednesday.

Yes, there's a problem. You can't hang drywall over the insulation until the electrical and plumbing rough inspections have been completed and approved.

Here's why:

Code Requirement: The electrical and plumbing rough inspections must be completed before insulation is installed (per most local codes, typically based on the International Residential Code - IRC). Since the insulation is already in, those inspections should have happened first.

Practical Issue: If the inspector finds code violations in the electrical or plumbing work, you'll need to tear out the insulation to make corrections. Hanging drywall over uninspected or failed rough-ins means you'll be cutting into finished walls later.

Recommended Action:

1. Stop - Don't hang drywall yet
2. Verify - Confirm with the GC that the electrical and plumbing rough inspections actually happened before insulation was installed
3. Inspect - If they haven't been inspected yet, schedule those inspections immediately
4. Proceed - Only hang drywall after all three inspections pass

The GC may be trying to compress the schedule, but this sequence puts the project at risk for rework and delays. It's better to address this now than have to tear out completed work later.

Tell the GC that proceeding as planned could result in having to remove the drywall if corrections are needed, which would actually delay the schedule more than waiting a day or two for proper inspections.

Yes, this plan violates code and creates major liability.

The Code Violation (IRC R109.1.3 / NEC 110.12 / UPC 103.5): You cannot conceal any work until the rough-in inspections for ALL trades are approved. Hanging drywall before the Wednesday inspections covers the electrical rough (boxes, cables, stapling, grounding), plumbing rough (DWV pressure test, water supply test, strapping), and insulation (R-value, vapor retarder, air sealing).

The Practical Consequences:

1. Failed Inspections: The inspector will fail the job if drywall is up. They cannot verify wire stapling (NEC 300.4), nailing plates, pipe slopes, or insulation contact.
2. Destructive Verification: You will be required to remove drywall to expose work for inspection. This destroys your Monday/Tuesday labor and material.
3. Schedule Impact: Re-hanging, taping, and drying pushes the schedule further than waiting 48 hours.
4. Liability: If a fire or leak originates in a concealed, uninspected cavity, insurance denies the claim. The GC owns this risk.

Correct Sequence:

1. Monday/Tuesday: Prep for inspections (label circuits, ensure access, verify insulation install).
2. Wednesday: Pass all three rough inspections (Elec, Plumb, Mech/Insulation).
3. Thursday+: Hang drywall.

Tell the GC: "I cannot hang until Wednesday inspections are signed off. IRC R109.1.3 prohibits concealing uninspected work. If we hang Monday, we fail Wednesday, and I have to rip it down. I’ll be ready to hang Thursday."
