Most standard home inspections in Central Ohio take about two to three hours on-site for an average house, with larger, older, or rougher properties pushing closer to three to four hours. Add 24 hours for the written report, and you're looking at roughly a day and a half from "inspector walks in the door" to "we have paper to work with." That sounds comfortable until you realize your inspection period is often only seven to ten days total, and the clock started ticking the moment you went under contract.
I've watched buyers miss repair-request deadlines because they scheduled the inspection on day five, got the report on day seven, and had two days left to review a 60-page document, call a plumber, get a number, and write a formal addendum. That's avoidable if you understand the full timeline before you need it.
What the Clock Actually Looks Like on Site
For a typical Columbus single-family home in the 1,500 to 2,500 square foot range, plan for two to three hours with the inspector on-site. That window covers the inspector physically working through every accessible system: the roof, attic, foundation, basement or crawlspace, HVAC, electrical panel, plumbing, and every room. If the house is larger, older, or showing signs of deferred maintenance, budget three to four hours without question.
A few things that reliably stretch the clock:
Multiple HVAC systems. A house with a furnace, central air, a separate mini-split, and a wood-burning fireplace takes longer than a ranch with one unit. Each system gets documented separately.
Basements and crawlspaces. Inspectors spend real time under houses when there's a crawlspace. Any standing moisture, vapor barrier damage, pier and beam issues, or pest evidence gets documented with photos, and that takes time to do right.
Deferred maintenance and flip work. A heavily renovated house actually takes longer than a well-maintained one, not less. When an inspector finds new drywall over an old wall, fresh paint on a damp basement, or recent work without permits, they slow down and document. That's the right call. Budget extra time on any house where the cosmetics are brand new but the bones are 1970s.
Detached garages, outbuildings, and pools. Each structure adds time. A two-car detached garage and an in-ground pool can add 30 to 45 minutes on their own.
Inaccessible areas. If the inspector can't get to the attic, can't reach the panel, or finds mechanicals blocked by storage, they either flag it as not fully inspected or spend time working around it. Both slow the clock and create issues to follow up on.
The rough rule of thumb inspectors use: add about 30 minutes for every additional 500 to 1,000 square feet beyond the baseline range. A 3,500 square foot house with a finished basement, three HVAC zones, and a detached workshop? You might be there four hours.
Report Delivery: Plan for the Same Day or Next Morning
A professional inspector doesn't hand you a report on the driveway. They go back and spend real time writing it up, organizing photos, and making sure the findings are clear. Most local inspectors working in the Columbus and Central Ohio markets deliver the report the same evening or by the next morning.
That means if you schedule an inspection for Wednesday at 9am, you'll likely have the report Thursday morning at the latest. If you scheduled for 2pm on Wednesday, Thursday morning is still realistic, but if there's any delay it could push to Thursday afternoon.
This matters because your response to the seller almost always has to happen within the inspection period, and some contracts specify a separate, shorter window for submitting repair requests once the report is in hand. Read your contract. I read it with you. Know what triggers what.
The Full Contract Window and Why It's Tight
Beyond the hours on-site, there's the full inspection period to manage. In the Columbus market, contracts typically give buyers seven to ten calendar days for the inspection period, though the exact number is whatever you negotiate. Most of my buyers go in with ten days when there's any room to negotiate it.
Here's what has to happen inside that window:
- Schedule the inspection (you can't always get next-day availability)
- Attend the inspection and do the walkthrough
- Receive and review the written report
- Identify anything material that needs a specialist look
- Bring in a plumber, electrician, structural engineer, or roofer if needed
- Get actual dollar numbers, not guesses
- Submit repair requests, a price reduction request, or decide to proceed as-is
If you schedule the inspection on day three and get the report on day five, you have five days left. That sounds fine until you call a plumber about the sewer scope finding and they can't get out until day eight. Now you're requesting an extension, which the seller can decline in a competitive market.
Schedule the inspection the first available slot after your offer is accepted. Day one or day two, not day five.
Add-On Inspections: They Run Concurrently, But Not Always
Radon tests, termite inspections, sewer scopes, chimney inspections, and oil tank sweeps are commonly added on in Central Ohio. Some can be done at the same time as the main inspection, others require a separate appointment with a separate specialist.
Radon tests: a continuous electronic monitor gets placed during the main inspection and pulled 48 hours later. That means if your inspection is on day two, you won't have radon results until day four at the earliest. Factor that into the timeline.
Sewer scopes: a plumber runs a camera through the sewer lateral from the cleanout to the street. This typically requires a separate appointment, though some inspectors offer it as an add-on they do themselves. In Columbus and in many of the older suburbs, sewer scopes are worth doing on anything built before 1990. Clay tile and cast iron lines fail in ways that don't show up anywhere else.
Chimney inspections: a separate sweep or inspector, separate appointment. If there's a wood-burning fireplace and you want a Level 2 inspection, add that to day one scheduling, not as an afterthought.
Each add-on adds time or a separate scheduling window. Know what you want before the inspection, not after.
What Buyers Should Do with This Information
Schedule the moment you go under contract. Don't wait for the title company to send the welcome email. Call your inspector the same day your offer is accepted and lock in the earliest available slot.
Plan to be there for the full inspection. This is two to three hours of your life that can save you five to six figures in surprises, or give you the leverage to negotiate real repairs. Show up, follow the inspector, ask questions. The debrief at the end of the inspection is where you learn what actually matters versus what's routine maintenance.
Clear your schedule after. Don't book back-to-back obligations the afternoon of your inspection. Give yourself an hour to debrief with the inspector and call me while the details are fresh. If something significant comes up, I need to know immediately so we can figure out the response strategy.
Know your deadlines before you go in. I walk through the contract timeline with every buyer before the inspection, not after. Know your inspection period end date, know your response deadline, know whether you have a radon contingency written in.
What Sellers Should Do with This Information
Make the house inspectable. That means clear access to the attic hatch, no boxes blocking the panel, nothing piled in front of the water heater, serviceable paths to the crawlspace. An inspector who can't access something either flags it as uninspected (which creates doubt) or spends time working around it (which slows things down and makes buyers nervous).
Don't hover. Buyers and their inspector need space. The more comfortable the inspector is, the more straightforward the process goes. Step out. Let it run.
Expect the buyer to need half a day. The inspection, the travel home, the phone calls, the report review. If the buyer asks for an extension for a valid reason, being difficult about it rarely helps you. The alternative is usually a termination.
Consider a pre-listing inspection. I've seen pre-listing inspections turn a complicated negotiation into a clean close more than once. When the seller already knows what's there, nothing comes out of the buyer's inspection as a surprise, and it's harder for a buyer to use a condition as a negotiation lever when the seller already disclosed it upfront and priced for it.
The Bottom Line on Timing
A home inspection in Central Ohio takes two to three hours on a standard house. Add 24 hours for the report. Add time for any specialty inspections you want. And then work backwards from your inspection period deadline to make sure there's enough room for a meaningful response if anything comes up.
