Home inspection in Orange County: what it covers and costs

What does a home inspection cover?

California law defines a home inspection as a look at a one to four unit home, without opening anything up, done for a fee when the home is being sold. The goal is to find serious defects in the mechanical, electrical and plumbing systems and the structural parts of the home. A serious defect is one that really affects the home's value, safety or livability; looks and style do not count. If there is a pool or spa, the inspector notes which of the state's seven drowning prevention safety features it has.

The InterNACHI standards list ten areas: roof, exterior, foundation and structure, heating, cooling, plumbing, electrical, fireplace, attic with its insulation and ventilation, and doors, windows and interior. The roof is inspected from the ground or the eaves. The inspector does not have to walk on it.

What does a home inspection leave out?

The standards say plainly that an inspection is not technically exhaustive. The inspector is not required to report on:

• Termites, rodents or other pests, or mold.
• Lead paint, asbestos or radon.
• The inside of flues and chimneys, or furnace heat exchangers.
• Underground items, such as utilities and sprinkler lines.
• Water pressure and flow rate, or gas leaks.
• Code compliance, how long a system will last, or what a repair will cost.
• Appliances, or anything behind furniture, rugs and stored boxes.

California's home inspection law does not let an inspector who is not a registered engineer do engineering analysis, so a structural concern in the report may come with advice to call an engineer.

Which add-on inspections matter in Orange County?

Each one fills a gap from the list above. Our other guides explain them, so this is when to order each:

• Sewer camera. The plumbing check tests drainage at the fixtures, and the standards never mention the sewer line. A camera shows the line to the street, which may be yours to fix. See who owns the sewer line in your city.
• Termite report. A licensed pest company writes it, separate from the home inspection. Whether escrow needs one depends on your contract and your lender. Our termite guide explains what the findings mean and why who pays is up to your contract.
• Roof. Worth a roofer's visit when the inspector could not get on the roof or the report flags wear. Our roof guide covers lifespans and when repair beats replacement.
• Slab leak test. Order one when the seller discloses a past leak, or you hear running water or feel a warm floor. Start with the meter test in our slab leak signs guide; the slab leak repair guide explains how leak detection works.
• Chimney. If you plan to use the fireplace, have the flue inspected first, then yearly as our fall maintenance guide explains.

How much does a home inspection cost?

HomeAdvisor, a contractor lead service, puts the national average at $344 from its customer surveys, with most paying $296 to $425 (updated June 19, 2026). That is not an Orange County price; we found no reliable local figure. What moves the price:

• The size and type of the home.
• The inspector's certifications and experience.
• Where the home is.
• Add-on inspections, which cost extra.

What should I ask a home inspector before hiring?

California has no license for home inspectors; the state's home inspection law sets their duties instead. An inspector who is not also a licensed contractor, pest control operator, architect or engineer has to do the job with the care a careful home inspector would use. So ask:

• Which standards do you follow, and can I see a sample report? The sample shows how clearly defects are written up.
• Will you walk the roof and go into the attic and crawl space? If not, you know what to order separately.
• Do you or your company do repairs? State law bars an inspector, or their company, from offering paid repairs on a house they inspected in the last 12 months, with narrow exceptions.
• Does your fee depend on anything? It may not depend on what the report finds or on escrow closing, and the inspector may not pay an agent or the owner for the referral.
• Does the contract limit your liability to the fee? In California a clause like that, or one that says the inspector owes you no care, does not hold up. A lawsuit over the report has to be filed within four years of the inspection.

Contractors do need a state license. Look up anyone who will do the repairs on the CSLB license check, by license number, business name or person. Termite companies are licensed by the pest board, covered in the termite guide.

What do I do with the report after closing?

Turn it into a first-year plan. Sort each finding into safety items to fix now, repairs that grow if they wait, and things to watch, then give each one a month. Our new homeowner checklist covers the rest of the first year: shutoffs, alarms and the tax bills.
