General Contractor Checklist for Building a House

A general contractor building a house must verify licensing and insurance, finalize plans and permits, schedule inspections, manage subcontractors, and track the budget and timeline from site prep to final walkthrough. Below is a practical checklist covering each phase, plus what to watch for so you don’t get surprised by costs or delays.

Before You Break Ground

The pre-construction phase sets the tone for the entire project. A responsible contractor will confirm the following before any dirt moves:

• Licensing and insurance: Verify the contractor’s state license is current and that they carry general liability and workers’ compensation. Ask for certificates and call the issuing agency to confirm they’re active.
• Signed contract and plans: The contract should include the full set of architectural drawings, a detailed scope of work, a payment schedule, and a timeline. Never rely on verbal promises.
• Permits and zoning: The contractor pulls all required building permits from the local jurisdiction. This includes checking setback requirements, height limits, and easements on the lot.
• Site survey and soil test: A boundary survey confirms where the house can sit, and a soil test informs the foundation design. Skipping the soil test can lead to cracks or settling later.
• Utilities and access: Confirm water, sewer or septic, electric, and gas connections are available and that the site has legal access for construction vehicles.

If the contractor hesitates on any of these, consider it a red flag. A good GC will walk you through each step and explain why it matters.

Budget and Payment Schedule

Most new home builds cost between $150 and $400 per square foot, depending on location, materials, and finishes, but these numbers vary widely. The contractor’s job is to turn your budget into a realistic line-item estimate. Key points to review:

• Allowances: These are placeholder amounts for items like cabinets, flooring, and fixtures. If you pick something more expensive, you pay the difference. Ask for a list of what’s included at the base price.
• Payment milestones: A typical schedule ties payments to completed phases, such as foundation, framing, rough-in, and final. Never pay more than 10% upfront, and avoid contractors who demand large deposits.
• Change order process: Any change to the original plan should be documented in writing with a new price and timeline. Unwritten changes are a common source of disputes.

A good rule: keep a 5–10% contingency fund for unexpected issues like rock in the excavation or a code change. The contractor should also provide a weekly or biweekly cost report so you always know where the money stands.

Site Preparation and Foundation

Once permits are in hand, the physical work begins. The contractor oversees:

1. Clearing and grading: The lot is cleared of vegetation, and the ground is leveled to direct water away from the foundation.
2. Excavation: Trenches are dug for footings and utilities. This is when the contractor discovers if there are buried rocks, old pipes, or poor soil.
3. Footings and foundation: Concrete footings are poured, then the foundation walls (concrete block, poured concrete, or insulated concrete forms). Waterproofing and drainage tile are installed before backfilling.
4. Slab or crawl space: For a slab, plumbing rough-ins are placed before the concrete pour. For a crawl space, the contractor installs a vapor barrier and vents.

After the foundation cures, the local inspector signs off before framing begins. This is a mandatory step—never let the contractor skip it to save time.

Framing, Rough-Ins, and Inspections

Framing is when the house takes shape. The contractor schedules the lumber delivery and coordinates the crew that builds the floor system, walls, and roof. Once the frame is up, the rough-in phase brings in the mechanical trades:

• Plumbing: Pipes for water supply, drains, and vents are run through the walls and floors.
• Electrical: Wiring, outlets, switches, and the panel are installed. The electrician also runs low-voltage lines for internet and cable.
• HVAC: Ductwork for heating and cooling is placed, along with the furnace or heat pump and water heater.
• Insulation: After rough-in, insulation is installed in walls, ceilings, and floors. This is a critical step for energy efficiency.

Most jurisdictions require three separate inspections: framing, rough-in (mechanical/electrical/plumbing), and final. The contractor is responsible for scheduling these and fixing any issues the inspector flags. A good GC will also do their own quality walkthrough before each inspection.

Finishes and Final Walkthrough

After the rough-in passes, the house gets its skin. Drywall is hung and taped, then paint, flooring, cabinets, countertops, and trim are installed. The contractor coordinates the final trades and ensures the work matches the approved plans. Near the end, they should:

• Complete a punch list of minor defects like nail pops, scratched paint, or a misaligned cabinet door.
• Schedule the final inspection with the local building department.
• Provide warranty documents for appliances, roofing, and mechanical systems.
• Give you a homeowner’s manual with maintenance schedules and contact info for each subcontractor.

Do the final walkthrough with the contractor. Test every door, window, faucet, and outlet. Check that the grading slopes away from the house and that gutters are installed. Don’t sign off until the punch list is complete.

Common Problems and How to Avoid Them

Even with a good contractor, issues arise. The most frequent include:

• Budget overruns: Usually from vague allowances or unexpected site conditions. Mitigate by reviewing the contract for what’s included and keeping a contingency.
• Schedule delays: Weather, material shortages, or subcontractor no-shows. Ask the contractor how they handle delays and whether the timeline has buffer built in.
• Communication gaps: You expect daily updates, the GC only calls when there’s a problem. Set expectations early about how often you’ll hear from them.
• Poor workmanship: Check references and visit a current job site. Look at the corners, trim, and foundation for signs of sloppy work.

If a dispute arises, refer to the contract’s dispute resolution clause. Many contracts require mediation before legal action.

How to Choose a General Contractor

Selecting the right GC is the most important decision you’ll make. Start by asking for referrals from friends, real estate agents, or local builders’ associations. Then:

• Interview at least three contractors and ask for references from the last two years.
• Verify their license and insurance with the state licensing board.
• Check their Better Business Bureau rating and any complaints filed.
• Ask how they handle change orders and what their typical schedule looks like.
• Get at least three bids and compare them line by line, not just the total.

A lower bid isn’t always better—it might mean cheaper materials or less experienced labor. Trust your gut: if the contractor is vague or pushy, move on.

Costs and Payment Pitfalls

Beyond the base construction cost, budget for land, permits, design fees, landscaping, and a temporary construction loan. The contractor’s payment schedule should be tied to milestones, not a calendar. Watch for these red flags:

• Requesting more than 10% down.
• Asking for cash payments.
• Refusing to put the payment schedule in writing.
• Pressuring you to sign before you’ve reviewed the contract.

If you’re financing the build, your lender will require a signed contract and may send an appraiser to check progress before releasing funds. The contractor should be familiar with the lender’s draw process.

Safety and Liability

Construction sites are dangerous. The contractor is legally responsible for site safety, including:

• Providing hard hats and safety gear for visitors.
• Securing the site with fencing or barriers.
• Ensuring subcontractors have workers’ comp coverage.
• Following OSHA regulations for scaffolding, ladders, and electrical work.

As the homeowner, you can protect yourself by requiring proof of insurance and never entering the site without the contractor’s permission. If you visit, wear sturdy shoes and a hard hat, and stay out of active work areas.

Frequently Asked Questions

Do I need a general contractor or can I act as my own?

You can be your own GC, but you’ll need to know local building codes, schedule trades, and handle permits and inspections. It can save 10–20% on the GC fee, but it’s a full-time job that requires experience. If you make a mistake, it can cost more than the fee you saved.

How long does it take to build a house?

A typical custom home takes 6–12 months from permit to completion, depending on size, complexity, and weather. A simple plan on a flat lot might be done in 4–6 months, while a large custom home can take over a year. Ask your contractor for a schedule with milestones.

What should be in the contract?

The contract should include the full plans, a detailed scope of work, a payment schedule tied to milestones, a start and completion date, a change order process, and a warranty clause. It should also name the subcontractors and specify materials and brands where possible.

How do I handle change orders?

Any change—even a small one—should be put in writing before work is done. The change order should state the new price, the impact on the schedule, and be signed by both parties. Never approve verbal changes; they lead to disputes.

What is a punch list and why does it matter?

A punch list is a final list of minor defects or incomplete items that the contractor must fix before you accept the house. It includes things like chipped paint, a crooked outlet, or a door that doesn’t latch. Walk through with the contractor, write everything down, and don’t make the final payment until the list is done.

Template: General Contractor Checklist

Building a house is a complex process, but with a solid checklist and a trustworthy contractor, you can keep it on track. If you’re financing the build, your lender may have additional requirements, so ask them early. And if you’re unsure about any legal or financial aspect, consult a real estate attorney or financial advisor.
