Two to four hours for most homes. The report arrives within 24 to 48 hours. The contingency deadline closes 5 to 14 days after the contract date — which leaves less response time than most buyers realize.
For a typical single-family home of 1,500 to 2,500 square feet, plan on 2 to 4 hours. That covers exterior, roof, attic, basement, all interior systems, the electrical panel, plumbing, HVAC, and major appliances. Add a 20 to 30 minute walk-through at the end where the inspector explains findings to the buyer in person.
A 1-hour inspection on a 2,500 square foot home is a red flag itself — the inspector rushed. A 5-hour inspection on the same home usually means the inspector is being thorough or has found issues worth documenting carefully.
National averages from inspector industry data and ASHI guidelines.
| Property type | Square footage | Typical duration |
|---|---|---|
| Condo or apartment | 500–1,200 sq ft | 1.5–2 hours |
| Townhouse | 1,000–1,800 sq ft | 2–2.5 hours |
| Small single-family | 1,200–1,800 sq ft | 2–3 hours |
| Average single-family | 1,800–2,500 sq ft | 2.5–4 hours |
| Large single-family | 2,500–3,500 sq ft | 3.5–5 hours |
| Larger or older homes | 3,500+ sq ft | 4–6 hours |
| New construction | Any | 2–3 hours (less mechanical history to document) |
Add 30–60 minutes for outbuildings, detached garages, septic, well, or pool inspections if those are part of the scope.
Most inspectors deliver the written report within 24 to 48 hours. Some offer same-day delivery for an extra fee. The report is usually a PDF, 30–80 pages with photos, organized by system. It includes severity ratings, photos of each issue, and recommendations.
Read the executive summary first — that's the inspector's editorial take on which findings actually matter. The body of the report flags everything visible, even routine maintenance. A 60-page report with three serious flags is a normal report. Don't panic at the page count.

The inspection itself is short. The contingency window is short too — typically 5 to 14 days from the contract date, including the time to schedule, inspect, receive the report, and respond. After the deadline, your right to renegotiate or walk away is gone.
Set a reminder the day you sign the contract. See the main home inspection reminder page for how the follow-up emails handle the deadline.
Set a reminder before the contingency deadline so the inspection report has time to matter.
Done in seconds. No sign-up required.
Two to four hours for a typical single-family home of 1,500–2,500 square feet. Smaller condos or new builds can run 90 minutes to 2 hours. Older homes, larger properties (3,500+ sq ft), and homes with outbuildings or detached structures can take 4–6 hours. Most inspectors block half a day.
For a home under 1,200 square feet — typically a small single-family or a townhouse — most inspections finish in 90 minutes to 2 hours. Condos with no exterior or roof scope can be even shorter. The walk-through with the buyer at the end usually adds another 20–30 minutes.
Most inspectors deliver the written report within 24 to 48 hours. Some same-day inspectors send a preliminary report within hours. The report is usually 30–80 pages with photos. Read the executive summary first — it lists the inspector's top concerns.
Older homes, larger square footage, multiple HVAC zones, septic and well systems, outbuildings, and detached garages all add scope. A thorough inspector who finds significant issues will also take longer documenting them. A 4–5 hour inspection is a sign of thoroughness, not delay.
Five to fourteen days in most U.S. residential contracts, measured from the contract effective date. The window includes the time to schedule, conduct, receive the report, and respond. Tight in practice — set a reminder for the deadline the day you sign.
You don't need to be present for the full inspection. Most buyers attend the last 30–60 minutes for the walk-through, where the inspector explains findings in person. If you do attend the full inspection, stay out of the inspector's way and ask questions at natural breaks.
