What to Expect During Your Custom Home Inspection Process in Indiana
By Michael Mercho ·
The home inspection process for a custom build is fundamentally different from inspecting an existing home. Instead of one inspection before purchase, custom homes undergo multiple inspections at critical construction milestones — each one required before the next phase can begin. Understanding this process helps you know what's happening, why it matters, and what to look for.
The Inspection Timeline
A custom home in Hamilton County typically goes through 8–12 inspections during construction:
1. Footing Inspection
Before concrete is poured for the foundation, the inspector verifies that footings are at the correct depth, width, and reinforcement. In Hamilton County, footings must extend below the frost line (42 inches in Central Indiana) to prevent heaving.
2. Foundation/Slab Inspection
After foundation walls are poured and before the slab is placed, inspectors check waterproofing, drain tile placement, and structural reinforcement. For walkout basements — common on lots in Fishers and Noblesville — additional waterproofing verification is required.
3. Framing Inspection
This is one of the most critical inspections. The inspector verifies:
- Structural connections (hangers, straps, hurricane clips)
- Proper header sizing over windows and doors
- Sheathing and weather barrier installation
- Fire blocking between floors
- Window and door rough openings
4. Mechanical Rough-In Inspections
Three separate inspections typically happen during this phase:
- Plumbing rough-in: Pipe sizing, slope, venting, and pressure testing
- Electrical rough-in: Wire sizing, box placement, GFCI/AFCI protection, panel capacity
- HVAC rough-in: Ductwork sizing, equipment placement, combustion air, and refrigerant lines
5. Insulation Inspection
Before drywall goes up, the inspector verifies insulation type, depth, and coverage. Gaps, compression, and missing insulation are caught at this stage — once drywall is installed, insulation problems are hidden and expensive to fix.
6. Final Inspection
The final municipal inspection covers everything: finished electrical, plumbing, HVAC operation, smoke and CO detectors, egress windows, handrails, and overall code compliance. Passing this inspection triggers the Certificate of Occupancy (CO), which allows you to legally move in.
Builder Quality Inspections vs. Municipal Inspections
Municipal inspections verify code compliance — they ensure the home is safe and legal. But code compliance is the minimum standard. A quality builder conducts their own inspections that go beyond code:
- Pre-drywall walkthrough with the homeowner to verify outlet placement, blocking locations, and framing details
- Quality checks at each phase by the project superintendent
- Third-party energy testing (blower door test, duct blasting)
- Final punch list walkthrough with the homeowner before closing
At Integra Builders, we invite our clients to participate in the pre-drywall walkthrough — it's the last time you'll see behind the walls, and it's the best opportunity to verify that everything is exactly where you want it.
What to Look for at Your Pre-Drywall Walkthrough
- Electrical outlet locations match your furniture layout and daily habits
- Blocking is installed for wall-mounted TVs, heavy mirrors, and future grab bars
- Ceiling fan boxes are in the right positions
- Window placement matches sight lines you discussed during design
- Any last-minute changes are documented before drywall seals everything

How many inspections does a custom home require in Indiana?
A custom home in Hamilton County typically requires 8–12 municipal inspections during construction, including footing, foundation, framing, plumbing, electrical, HVAC, insulation, and final inspections. Quality builders conduct additional internal inspections beyond what the municipality requires.
What is a pre-drywall walkthrough?
A pre-drywall walkthrough is an inspection conducted with the homeowner after framing and mechanical rough-ins are complete but before drywall is installed. It's your last opportunity to see behind the walls and verify outlet placement, blocking, window positions, and any custom details. Integra Builders includes this as a standard part of every build.
What happens if a home fails an inspection?
Failed inspections are common and not cause for alarm. The builder corrects the issue and schedules a re-inspection. Common failures include minor electrical corrections, insulation gaps, and missing fire blocking — all easily fixed before the next phase begins. A competent builder anticipates inspection requirements and rarely has significant failures.
