ASHI vs. InterNACHI: Standards of Practice Comparison

Paper Checklist vs. Digital Inspection Software
A paper checklist is a great starting point — but professional inspectors increasingly use digital tools to capture photos, annotate findings on-site, and deliver branded PDF reports the same day. Here's how the two approaches compare.
Paper / PDF Checklist
Manual photo documentation
Handwritten notes — hard to read
Reports take hours to assemble
No branding or professional formatting
Easy to miss items under pressure
HomeInspecto Digital
Capture & annotate photos on-site
Typed findings with drop-down deficiencies
Branded PDF report generated instantly
Your logo, colors, and contact on every report
Guided workflow — never miss a section
Ready to go beyond the paper checklist? HomeInspecto turns this entire checklist into a guided digital workflow — with photo capture, annotation, deficiency tracking, and same-day branded PDF delivery from your phone.
This checklist serves three distinct audiences — each with different needs but the same goal: making sure nothing gets missed during a property evaluation.
Licensed Home Inspectors
Use as a field reference alongside your reporting software. Ensure every ASHI/InterNACHI SOP section is covered before leaving the property. Or switch to HomeInspecto's digital version for photo capture, annotation, and branded PDF delivery.
Home Buyers
Prepare for your inspection by understanding what your inspector will evaluate. Follow along during the walkthrough, ask informed questions, and use the checklist to review your inspection report against what should have been covered.
Real Estate Agents
Share the checklist with your buyer clients before their inspection. It demonstrates professionalism, sets expectations for what will be evaluated, and helps clients understand the report they'll receive — leading to smoother negotiations.
Home Inspection Cost & ROI: 2026 Numbers
A professional home inspection is one of the highest-ROI investments in the entire home buying process. Here's what the current market data shows.
$350–$500
Average inspection cost (2026)
Up approximately 5% from 2025. Varies by home size, age, and location. Larger homes and older properties trend higher.
$14,000
Average negotiated savings
Buyers who use detailed inspection findings negotiate an average of $14,000 off the purchase price in repair credits or price reductions.
86%
Inspections finding issues
The vast majority of home inspections uncover deficiencies requiring attention — from minor maintenance to major safety concerns.
65%
New construction with issues
Even brand-new homes benefit from inspection. Nearly two-thirds of new construction inspections reveal issues during the building process.
Specialty Add-On Inspections
Beyond the standard home inspection, there are several specialty inspections that address environmental, structural, or system-specific concerns. These are not included in a standard inspection but can be critical depending on the property's age, location, and features.
Radon Testing
$150–$250
Measures radon gas levels in the home. EPA recommends mitigation above 4 pCi/L. Essential in high-radon zones.
Mold Inspection
$200–$600
Visual and air-sample testing for mold presence. Recommended when water damage, musty odors, or visible growth is observed.
Sewer Scope
$125–$400
Camera inspection of the main sewer line from house to street. Identifies root intrusion, bellies, offsets, and line material.
Termite / WDI
$75–$150
Wood-destroying insect inspection. Required by many lenders for FHA/VA loans. Checks for termites, carpenter ants, beetles.
Pool & Spa
$100–$500
Evaluates pool structure, equipment, pumps, heaters, safety barriers, and electrical bonding. Important for liability.
Asbestos Testing
$200–$800
Lab analysis of suspected asbestos-containing materials. Common in homes built before 1980 — insulation, floor tiles, siding.
Frequently Asked Questions
What does a home inspection checklist include?
A comprehensive home inspection checklist covers all major systems defined by ASHI and InterNACHI Standards of Practice: structural, roofing, exterior, electrical, plumbing, HVAC, interior, insulation and ventilation, fireplaces and chimneys, and appliances. Our checklist includes 200+ individual items across these 10 categories.
Is this checklist ASHI and InterNACHI compliant?
Yes. The checklist is aligned with both the ASHI Standard of Practice and the InterNACHI Home Inspection Standards of Practice. It covers the union of both standards, so every required system and component is included regardless of which association your state references. Book a demo to see how HomeInspecto builds these standards into a guided digital workflow.
How much does a home inspection cost in 2026?
Home inspections in 2026 average $350–$500 nationally, depending on home size, age, and location. Specialty add-on inspections like radon ($150–$250), mold ($200–$600), sewer scope ($125–$400), and termite/WDI ($75–$150) are additional. The investment typically pays for itself — buyers negotiate an average of $14,000 in savings using inspection findings.
Can I do a home inspection myself?
While a homeowner checklist is useful for routine maintenance, it cannot replace a professional evaluation. Licensed home inspectors have specialized training in construction, building systems, and safety standards — plus the experience to identify deficiencies that untrained eyes often miss. Use this checklist to prepare for your inspection and follow along during the walkthrough.
How can I get this checklist as a digital workflow?
HomeInspecto turns every checkpoint on this page into a guided digital inspection flow — with photo capture, annotation, deficiency tracking, and same-day branded PDF delivery from your phone. Book a demo and we'll walk you through the full workflow, or start a free trial to try it yourself.
How long does a home inspection take?
A standard residential inspection takes 2–4 hours depending on home size, age, and conditions found. Larger or older homes with more systems and components naturally take longer. Reports are typically delivered within 24–48 hours — or same-day with digital tools like HomeInspecto.
