The fundamental difference
A general home inspection is a top-to-bottom visual evaluation of the home's structure and systems. A sewer scope is an instrument-based subsurface inspection of one specific system — the buried lateral. They are complementary, not substitutes. Most importantly: a general home inspection in Minnesota does not include the sewer line. This surprises buyers constantly.
What a Minnesota home inspection actually covers
Per ASHI/InterNACHI standards of practice, a general home inspection covers:
- Roof, attic, insulation, ventilation
- Exterior cladding, windows, doors, grading
- Foundation, basement, crawl spaces (visible portions)
- Interior walls, ceilings, floors, stairs
- Plumbing fixtures, visible supply and drain piping, water heater
- Electrical service, panels, outlets (sample testing)
- HVAC equipment and controls
- Built-in appliances
It is fundamentally a visual inspection of accessible components. If it requires special equipment or excavation, it is outside the scope of practice — by definition.
What a general home inspection does NOT cover
| Excluded item | Why |
|---|---|
| Sewer lateral (foundation to city main) | Buried, requires camera |
| Water supply line from street | Buried, requires excavation or specialty test |
| Inside walls (electrical, plumbing) | Not visible without demo |
| Inside chimneys, ductwork | Requires specialized scope |
| Radon, mold, asbestos, lead | Separate testing protocols |
| Septic systems | Separate specialty inspection |
| Well water quality | Lab testing required |
Do you need both?
For any Minnesota home built before 1990: yes. The general inspection will catch the roof, electrical, and structural issues. The scope will catch the single most expensive surprise that hides under your foundation. Skipping either is leaving money — and risk — on the table.
For newer homes (1990+) with no mature trees and no backup history: the general inspection is essential, the scope is recommended but lower-priority. Use the calculator to see how much the marginal cost is when bundled.
Across 5,113+ MN inspections we've documented, 22% of homes that passed a general inspection cleanly had a significant sewer defect on the same visit's scope.
How they integrate on the same visit
Our Scope + Full Inspection bundle runs both inspections on a single appointment with a single inspector, producing a single combined report. The general inspection covers the home above ground; the scope covers the lateral below. Same trip, same inspector, same report — at a meaningful bundle discount versus booking them separately.
Frequently Asked Questions
Does a home inspection include the sewer line?
No. Per ASHI and InterNACHI standards, sewer laterals are explicitly outside the scope of a general home inspection. They require a separate camera inspection.
Can the same inspector do both?
Yes — our inspectors are trained and equipped for both. The Scope + Full Inspection bundle handles them on a single visit.
Which one should I get first?
Order both at once. They produce one combined report, and the bundle pricing is meaningfully less than booking them separately.
Is a Minneapolis truth-in-housing report the same?
No. A Minneapolis or St. Paul TISH report is a city-required disclosure inspection focused on health-and-safety items. It does not include a sewer scope.
Will my agent or lender require both?
Most MN agents recommend both for pre-1990 homes. Lenders typically don't require either — these are buyer-protection tools, not loan requirements.
