A garage conversion touches structural, electrical, plumbing, and HVAC work, often through several different subcontractors. The general contractor's job is to manage all of that — which means the questions that matter most are less about their taste and more about how they run a job.
Licensing and insurance
- Are you licensed for this type of work in this state, and can I see the license number? Verify it independently with your state licensing board rather than taking their word for it.
- What insurance do you carry, and can I get a certificate naming me? You want both general liability and workers' compensation confirmed — without workers' comp, an injury on your property can become your liability.
The permit and the bid
- Who pulls the permits — you or me? A contractor who avoids pulling permits, or suggests skipping them, is a red flag on a project this size.
- Can I get a detailed written bid, not a verbal estimate? A real bid breaks down labor and materials by category (electrical, plumbing, framing, finishes) rather than giving one lump number.
- What's included versus what's an allowance? Fixtures, flooring, and cabinetry are often budgeted as an "allowance" — a placeholder number you can exceed. Know which line items are fixed and which are estimates.
Money and timeline
- What's the payment schedule? Payments should be tied to completed phases, not front-loaded. Many states cap the legal deposit amount — worth checking your state's rule before agreeing to a large upfront payment.
- What's the realistic timeline, including permitting? Ask specifically whether the estimate includes permit review time, which is often the least predictable part of the schedule.
- How do change orders work? Get the process for approving and pricing changes in writing before you need it — not after a mid-project surprise.
Track record
- Have you done garage conversions specifically, not just general remodels? The mix of structural, egress, and utility work is different enough from a kitchen remodel that direct experience matters.
- Can I see two or three references from projects like this one? Ask each reference directly whether the project finished on budget and on schedule — not just whether they liked the finished result.
What happens when something goes wrong
- What happens if you find a structural or utility surprise once the walls are open? A good contractor has a clear process for pricing and approving unexpected work, rather than just adding to the bill.
- What's the warranty on the work, and who do I call if something fails after you're done? Get this in writing, including what's covered and for how long.
Bring a real number to this conversation. Knowing the typical cost breakdown before you talk to contractors makes it much easier to spot a bid that's missing something. See Garage Conversion Cost Guide 2026.
