Home Inspection Checklist: What to Check Before Buying a House

Overview

A home inspection is a visual review of the property’s accessible structure, systems, and components. It is not the same as a property appraisal. An appraisal generally supports a lender’s assessment of value, while an inspection helps a buyer understand condition and potential repair needs. For more detail on the distinction, see our home appraisal checklist.

Inspection standards, report formats, and buyer protections vary by location, so treat this checklist as a practical starting point rather than a legal or technical standard. The inspector may not move furniture, open finished walls, dismantle equipment, or access unsafe or restricted areas. If the inspection identifies a concern, ask whether a qualified specialist should investigate it further.

Before the appointment, review the purchase contract. If it includes a home inspection contingency, note the deadline for completing the inspection and responding to the report. A contingency may allow a buyer to negotiate, request repairs, seek a credit where permitted, or withdraw under defined terms, but the exact options depend on the contract and local rules.

Checklist by scenario

For every house

• Site and drainage: Look for standing water, soil sloping toward the building, eroded areas, damaged retaining walls, and downspouts that discharge too close to the foundation.
• Foundation and structure: Note visible cracks, uneven floors, sticking doors, gaps around windows, sagging areas, and signs of movement. Not every crack indicates a structural problem, but significant or unexplained movement deserves professional evaluation.
• Roof and attic: Check the visible roof covering, flashing, valleys, gutters, downspouts, attic ventilation, insulation, stains, dampness, daylight through the roof, and signs of pests. Ask about the roof’s age and any available repair records.
• Exterior: Inspect siding, masonry, trim, paint, decks, balconies, porches, steps, railings, driveways, paths, fences, and exterior doors. Pay particular attention to areas where water could enter.
• Plumbing: Run accessible taps, check water pressure and drainage, look beneath sinks for leaks, inspect visible supply and waste pipes, and note the water heater’s condition, location, and discharge arrangement. Ask whether the property has experienced leaks, flooding, or frozen pipes.
• Electrical: Check the main panel, visible wiring, outlets, switches, fixtures, and safety devices where accessible. Ask the inspector to identify outdated, damaged, overloaded, or ungrounded components and whether an electrician should assess them.
• Heating and cooling: Test accessible controls, review the condition of the furnace, boiler, heat pump, air conditioner, radiators, ducts, and flues, and ask about service history. An inspection does not replace specialist testing for fuel-burning equipment or indoor air quality.
• Moisture and ventilation: Look for musty smells, staining, condensation, peeling finishes, soft materials, damaged caulking, and inadequate bathroom or kitchen ventilation. Moisture sources should be identified before cosmetic repairs are considered.
• Interior and safety: Check windows, doors, locks, stairs, handrails, floors, ceilings, walls, fireplaces, smoke alarms, carbon monoxide alarms, and visible fire hazards. Confirm that bedrooms and living areas have practical emergency escape routes where applicable.
• Appliances and fixtures: Test included appliances where the inspection service covers them, but do not assume a basic inspection guarantees their future performance. Record the make, model, age, and condition of older or unusual equipment.

For a condo, townhouse, or managed development

Inspect the unit itself, then investigate shared responsibilities. Ask for the association or management documents, maintenance history, insurance information, planned works, reserve information, and any notices concerning building defects or special assessments. Confirm which party maintains the roof, exterior walls, windows, balconies, plumbing risers, heating systems, and shared drainage. Our guide to evaluating association dues and special assessments can help with the financial side of this review.

For an older, renovated, or vacant property

Older homes may need closer attention to wiring, plumbing materials, insulation, ventilation, structural alterations, and previous additions. For a renovated property, ask for permits, plans, warranties, and invoices where relevant. A vacant home may conceal leaks, pest activity, frozen pipes, or neglected heating and ventilation, so request records and arrange targeted testing when appropriate.

What to double-check

Walk through the property with the inspector if permitted. Take notes rather than relying only on the final report, and ask for plain-language explanations of material findings. Useful questions include:

• Which findings are safety concerns, active damage, deferred maintenance, or ordinary wear?
• What should be repaired before closing, and what can reasonably be planned after moving in?
• What evidence suggests an issue is active rather than historical?
• What further evaluation is needed from a structural engineer, electrician, plumber, roofing contractor, pest professional, environmental specialist, or other qualified expert?
• Could the problem affect insurance, financing, habitability, or resale?
• What areas could not be inspected, and what might be hidden behind finishes or stored belongings?

Check the report against your own observations and the seller’s disclosures. A clean-looking room does not prove that concealed systems are sound, and a minor visible defect can sometimes point to a larger moisture or drainage problem. Ask for supporting documents for recent work, including permits, warranties, service records, and receipts when available.

Separate the inspection findings from your affordability decision. Repairs, maintenance, insurance, property taxes, association costs, and other ownership expenses belong in the wider budget. Use the home affordability planning guide and estimate transaction expenses with the closing costs calculator guide before deciding whether the property remains suitable.

Common mistakes

• Skipping the inspection because the home looks well maintained: Appearance cannot confirm the condition of inaccessible systems, drainage, wiring, or structure.
• Using the inspection as a negotiation wish list: Focus on material defects, safety issues, active damage, and costs that affect the decision. Normal wear is not automatically a seller obligation.
• Assuming the inspector will test everything: Confirm the inspection’s scope, exclusions, and limitations before the appointment.
• Ignoring specialist recommendations: An inspector can identify a concern without providing the specialist diagnosis or repair estimate needed to assess it.
• Missing deadlines: Record the inspection date, report delivery date, contingency deadline, and any notice requirements in the contract.
• Accepting a repair without verification: Request documentation, confirm who will perform the work, and consider a follow-up inspection for significant repairs.
• Confusing an appraisal with an inspection: A value assessment does not replace condition-focused due diligence.

When to revisit

Revisit this checklist before every inspection, especially after the property type or season changes. A winter inspection may highlight heating, insulation, ice, and drainage concerns, while a wet season can make leaks and grading problems easier to identify. A summer visit may provide better access to roofs, yards, exterior finishes, and ventilation equipment.

Return to the checklist whenever the seller provides new disclosures, completes repairs, changes the contract, or gives access to previously restricted areas. Update your questions if the property has an addition, swimming pool, septic system, well, solar equipment, retaining wall, private road, shared amenities, or unusual heating system. These features may require separate records or specialist assessments.

After receiving the report, create three lists: issues requiring immediate specialist advice, repairs to address before or shortly after closing, and routine maintenance to budget for later. Compare those lists with your financing, insurance, and moving plans. If the findings materially change the cost or risk of ownership, pause before committing and obtain professional advice on your contractual options.

The practical next step is to print or save this house inspection checklist, add property-specific questions, and review the inspection report against the contract deadline. A careful inspection cannot eliminate every future repair, but it can help you make a better-informed buying decision and plan for ownership realistically.
