Building a House Checklist

The checklist below covers the 14 major phases of a residential build. Each phase includes the high-impact checks that are easiest to miss and hardest to fix later.

1. 1. Pre-construction planning

   Lock your budget, scope, and team before anyone breaks ground. This is where most $20K+ mistakes are born.

   • Set a hard budget with a 10–15% contingency reserve.
   • Confirm zoning, setbacks, and permit requirements with your municipality.
   • Hire a builder or GC only after checking references, licenses, and insurance.
   • Review architectural plans for missing dimensions, room sizes, and window placements.
   • Get soil tests and a site survey to avoid foundation surprises.

2. 2. Site preparation

   Clear, grade, and stake the lot so the foundation crew starts on a level, well-drained surface.

   • Remove topsoil and store it for final grading.
   • Install erosion control and sediment fencing.
   • Mark utility lines and confirm water/sewer tap locations.
   • Verify the build footprint matches the approved plans.

3. 3. Foundation

   Everything rests on this. Catch slab, footing, and waterproofing errors before they’re buried.

   • Inspect footings for depth, width, and rebar placement before the pour.
   • Check anchor bolt and hold-down spacing against structural drawings.
   • Verify drainage planes, damp-proofing, and perimeter drain placement.
   • Document the slab pour date and any cracks or level issues.

4. 4. Framing

   Walls, floors, and roof structure define every room. Measure twice before drywall hides it.

   • Confirm wall spacing, openings, and ceiling heights match plans.
   • Check for plumb, straight, and level walls on every floor.
   • Verify beam and header sizes above wide openings.
   • Inspect roof trusses and sheathing nailing patterns.

5. 5. Exterior shell & roofing

   Seal out water and air before you move inside. Flashings are the #1 source of future leaks.

   • Inspect house wrap, flashing, and window/door sealing.
   • Verify roof underlayment and shingle installation details.
   • Check soffit, fascia, and gutter alignment.
   • Confirm exterior penetrations are sealed and caulked.

6. 6. Rough plumbing

   Pipes and drains are hard to fix once covered. Verify locations and slopes now.

   • Confirm fixture locations, pipe sizes, and drain slopes.
   • Test water pressure and inspect joints before closing walls.
   • Verify venting layout and water heater placement.
   • Photo-map every pipe before insulation goes in.

7. 7. Rough electrical

   Outlets, switches, lighting, and panel capacity should match your lifestyle before drywall.

   • Count outlets per room and verify spacing against code.
   • Check switch locations and three-way switching plans.
   • Confirm panel size, circuit labels, and surge protection.
   • Test all rough wiring before wall close-up.

8. 8. HVAC & mechanical

   Comfort and air quality depend on proper duct sizing, returns, and venting.

   • Verify unit sizing matches the Manual J load calculation.
   • Check return-air pathways and supply register placement.
   • Inspect duct sealing and insulation.
   • Confirm combustion venting for gas appliances.

9. 9. Insulation & air sealing

   Thermal comfort and energy bills are decided here. Gaps are invisible but expensive.

   • Inspect insulation type, R-value, and coverage in walls, attic, and rim joists.
   • Check air sealing around windows, doors, penetrations, and top plates.
   • Verify vapor barrier location based on climate zone.
   • Document any missed or compressed areas.

10. 10. Drywall & interior finishes

    The stage where flaws become visible. Catch texture, paint, and trim issues early.

    • Check drywall seams, nail pops, and corner bead before texture.
    • Verify paint/primer coverage and color consistency.
    • Inspect interior trim, door clearances, and hardware alignment.
    • Confirm stair railing height, spacing, and handrail continuity.

11. 11. Flooring, tile & cabinets

    Finish materials are the most visible part of the house. Quality checks pay off every day.

    • Verify tile layout, grout, and waterproofing in wet areas.
    • Check hardwood/lvp transitions, expansion gaps, and levelness.
    • Inspect cabinet level, hardware, and soft-close function.
    • Confirm countertop seams, overhangs, and cutouts.

12. 12. Plumbing & electrical finish

    Fixtures, outlets, and switches get wired in. Make sure everything works and is accessible.

    • Test every outlet, switch, GFCI, and light fixture.
    • Run water and check for leaks, pressure, and drain flow.
    • Confirm hot/cold orientation on faucets and showers.
    • Verify exhaust fans and range hood venting.

13. 13. Exterior hardscape & grading

    Water should drain away from the house, not toward it. Finish grading protects the foundation.

    • Confirm final grade slopes away from the foundation (6 inches in 10 feet minimum).
    • Check driveway, walkway, and patio pitch and drainage.
    • Verify downspout extensions and splash blocks.
    • Inspect seed/sod, irrigation, and landscape drainage.

14. 14. Final inspections & punch list

    Before closing, walk every room and verify that the final inspector’s list is complete.

    • Schedule final building, plumbing, electrical, and HVAC inspections.
    • Create a written punch list with photos and deadlines.
    • Verify builder addresses every item before final payment.
    • Keep all permits, inspection approvals, and manuals.
