Hiring a General Contractor for Interior Work: Questions Worth Asking Before You Sign

Why the Interview Stage Matters as Much as the Work Itself

Hiring a general contractor (GC) for interior work — a kitchen remodel, bathroom addition, or whole-floor renovation — is one of the more consequential decisions a homeowner can make. A misaligned scope, a missing permit, or a poorly structured payment schedule can turn a promising project into a costly dispute.

The interview and vetting stage is your best window to catch problems before they're baked into a signed contract. The questions in this checklist are designed to surface the details contractors are sometimes reluctant to volunteer and help you compare bids on an apples-to-apples basis.

If you're still deciding whether to hire out or tackle part of the project yourself, see our DIY vs. professional installation guide for a side-by-side breakdown of skill requirements and cost trade-offs.

What to Gather After the Interview

Once you've asked your questions and received bids, you'll want to cross-reference a few items before signing anything. First, verify the contractor's license number through your state licensing board — most states publish an online lookup tool. Confirm their general liability and workers' compensation certificates name your project address and are current.

Bid interpretation is its own skill. Allowances, exclusions, and cost-plus language can make two bids look similar when one is actually open-ended. Our guide on reading a renovation bid walks through the line items most likely to shift mid-project.

Permit responsibility is another area to clarify in writing. In most U.S. jurisdictions, the party who pulls a permit assumes legal responsibility for code compliance. If a contractor says permits aren't needed for your scope of work, verify that independently. Our article on interior renovation permits explains which projects typically require approval and how to check local rules.

For projects that expand into structural, plumbing, or electrical territory — such as adding a bathroom — confirm the GC has licensed subcontractors for those trades, not just general laborers.

Keeping the Project on Track After You Sign

A signed contract is the start of an ongoing relationship, not the finish line. Designate a single point of contact on both sides and agree on how change orders will be submitted and approved — in writing, every time. Even small scope additions should go through a formal written change order to avoid billing disputes at the end.

Schedule regular walkthroughs at key milestones (framing, rough-in, drywall, finish) rather than waiting until the project is complete to raise concerns. Photos taken at each stage create a useful record if questions arise later. Your seasonal home inspection checklist can also help you monitor the finished work in subsequent years and catch any settling issues early.
