Home Inspection Checklist: What Gets Checked

Home Inspection Checklist

What the inspector's list actually contains

Checklist searches are the second biggest block in our home inspection demand data, coming from two directions at once: buyers wanting to know what the inspection will cover, and house hunters wanting a pocket version for the showing itself. Both are legitimate, and the professional list is public knowledge, published in the standards of practice inspectors work to.

A standard inspection walks the major systems: roof and attic, structure and foundation, exterior and drainage, electrical panel and wiring, plumbing supply and drains, heating and cooling, insulation and ventilation, windows and doors, and the built-in appliances. For each, the inspector reports condition, visible defects, safety issues and approximate remaining life where honest estimation is possible.

Your pocket version does something different: it filters houses before you pay for professionals. Water stains on ceilings, doors that will not latch, bouncy floors, a panel full of mismatched breakers, an HVAC unit older than the listing photos admit. Finding two or three of these on a showing does not kill a deal, but it shapes the offer and tells you where the paid inspection should dig.

The checklist, system by system

What gets examined in each area and the classic finding in each.

Roof, attic and ventilation

Covering condition, flashing, sheathing from the attic side, insulation depth and airflow. Classic findings: aged shingles, improvised patches and bathroom fans venting into the attic.

Structure and foundation

Visible foundation, framing, floors and cracks that matter versus cracks that do not. Doors out of square and sloping floors send inspectors straight to the crawl space.

Exterior and drainage

Siding, trim, grading, gutters and where the water goes. The cheapest expensive problem in housing is a downspout dumping against the foundation.

Electrical

Service panel, breaker sizing, grounding, GFCI protection and a sampling of outlets. Classic findings: double-tapped breakers, missing GFCIs and amateur junctions.

Plumbing

Supply pressure, drain speed, water heater age and condition, visible piping and signs of past leaks. Material vintage, from galvanized to polybutylene, gets flagged by era.

HVAC and appliances

Heating and cooling operation, age, filters, ducts and the built-in appliances run through a cycle. Age versus expected lifespan drives the negotiation math.

What the checklist cannot see

Every professional checklist ends with a limitations section, and it matters: inspections are visual and non-invasive. Nothing behind finished drywall, under slabs or inside sewer lines is on the list, which is what specialty add-ons like sewer scopes, radon tests and pest inspections exist to cover.

Use the checklist accordingly. It is a powerful filter and a negotiation engine, not a guarantee, and the houses that pass it can still hold surprises in the systems it cannot reach.

How to put the checklist to work

1

Pre-screen at showings

Carry the pocket version: water stains, floor slopes, panel condition, HVAC age, drainage. Ten minutes of looking saves inspection fees on houses that fail early.

2

Brief your inspector

Hand over your observations before the inspection starts. Pointing a professional at your worries is exactly what the appointment is for.

3

Turn findings into a plan

After the report, sort items into safety now, budget soon and cosmetic whenever. That sorted list is your negotiation sheet and your first-year maintenance plan.

Home Inspection Checklist questions, answered straight

Can I just use a checklist instead of hiring an inspector?

A checklist finds the visible ten percent; a professional finds the patterns behind it. Use your list to filter houses and shape questions, and the professional to protect the actual purchase.

What are the biggest red flags on a showing?

Fresh paint on one ceiling patch, doors that stick or will not latch, sloping floors, a rusty or crowded electrical panel, soft bathroom floors and grading that tilts toward the house. None are verdicts; all are reasons to dig.

Does the inspection cover appliances?

Built-in appliances get run through a basic cycle under most standards. Freestanding items like washers and fridges are commonly excluded or noted only, so test them yourself at the final walkthrough.

What should I do during the inspection?

Attend, follow, and ask what matters versus what is cosmetic. Inspectors triage constantly, and hearing that triage out loud is worth as much as the written report.

Is there a checklist for sellers too?

The same list read in reverse: fix the cheap and visible items, service the HVAC, clear access to panel, attic and crawl space, and consider a pre-listing inspection so nothing in the buyer's report surprises you.
