What Drives Your Cost
What a Complete Scope Includes

Preparation

Lot clearing and debris removal

Clearing trees, brush, and old debris to create a flat, clean building area.

Leaving roots or hidden debris can damage your new foundation later.
Soil testing and compaction

Testing your soil type and compacting it properly before the foundation is poured.

Poor compaction leads to settling cracks in floors and walls over time.
Grading for water drainage

Grading the lot so rainwater flows away from the house and foundation.

Bad grading often causes basement leaks and water pooling near the house.

Foundation

Footings below frost line

Digging footings deep enough for Midwest winters to prevent ground shifting.

Shallow footings can crack and heave when the ground freezes and thaws.
Rebar in footings and walls

Installing steel rebar reinforcement in all concrete footings and walls.

No rebar means weaker concrete that cracks more easily over time.
Vapor barrier under slab

Placing a heavy plastic barrier under the concrete slab or basement floor.

Skipping this lets moisture rise into your living space and cause mold.
Anchor bolts for framing

Securing the house frame to the foundation with proper anchor bolts.

Framing

Quality lumber or engineered wood

Using straight, high-grade lumber or engineered wood as shown in plans.

Cheap or warped lumber can cause squeaky floors and crooked walls.
Proper sheathing and bracing

Covering walls with sheathing and adding bracing for wind resistance.

Insufficient bracing may fail local building code inspections.
Rough openings sized correctly

Framing exact openings sized for your chosen doors and windows.

Exterior

Full roofing system installed

Installing complete roofing with underlayment, shingles, flashing, and vents.

Cutting corners on roofing leads to leaks that are expensive to fix later.
Siding and trim as specified

Applying exterior siding, trim, soffits, and paint or stain you choose.

Windows and doors sealed properly

Installing all windows and doors with flashing and sealing around every opening.

Poor sealing causes drafts, water leaks, and higher energy bills.

Mechanical Systems

Plumbing rough-in complete

Running all water supply and drain lines before walls are closed up.

Incomplete rough-in means tearing open finished walls for expensive fixes.
Electrical wiring per code

Wiring the entire house with enough outlets, switches, and circuits as planned.

Undersized wiring can cause overloaded circuits and fire hazards.
HVAC system properly sized

Installing heating and cooling equipment sized correctly for your home.

Wrong size system runs inefficiently, wears out faster, and costs more to operate.

Interior Finishes

Insulation in all areas

Insulating walls, attic, and floors to meet or exceed local energy codes.

Cheap or missing insulation makes your home cold in winter and expensive to heat.
Drywall hung and finished

Hanging drywall, taping seams, and sanding for smooth walls and ceilings.

Flooring and trim as chosen

Installing your chosen flooring, baseboards, and interior trim work.

Using lower-grade materials than agreed leads to disappointment after move-in.

Cleanup and Restoration

Daily job site cleanup

Keeping the construction site tidy and safe every single day.

Messy sites create safety hazards and can upset neighbors.
Final house cleaning

Thorough cleaning of the entire home inside and out before you move in.

Yard restoration after build

Grading, seeding, and restoring the yard around the new house.

Leaving the yard torn up means extra work and expense for you later.

Permits and Inspections

Contractor pulls all permits

Contractor obtains the building permit and any other required approvals.

Some contractors ask you to pull permits, which slows everything down.
All inspections scheduled and passed

Contractor schedules and ensures every required inspection passes.

Skipping or rushing inspections can hide code violations that cost you later.
Red Flags — Corners Contractors Cut
  • Skipping proper soil compaction before pouring the foundation
  • Using shallow footings that do not meet local frost line depth
  • Installing cheap or warped lumber for framing
  • Skipping vapor barriers under slabs or in crawl spaces
  • Rushing or skipping required building inspections
Questions to Ask Every Contractor
  1. Will you obtain all building permits and schedule every required inspection?
  2. What warranties do you provide on the foundation, framing, and major systems?
  3. How do you handle changes or upgrades during the build process?
  4. Can you share references from recent new home builds in this area?
  5. What is your estimated timeline from start to move-in ready?
Permits

New home construction always requires a building permit and multiple stage inspections in every US jurisdiction. Ask your contractor exactly which permits they will handle and if they will schedule all inspections themselves.
