A standard home inspection in Denver costs between $350 and $700 for homes under 3,000 square feet. The price varies based on square footage and optional add-on services like radon testing or sewer scopes. Here’s a complete guide to home inspection costs in Denver so you know what to pay before you close.
How long does a home inspection take in Denver?
The average home inspection takes 2 to 4 hours. The exact duration depends on several factors, including the square footage, age, and complexity of the home.
During that time, home inspectors evaluate every major system, including the roof, foundation, HVAC, plumbing, and electrical. Below is a chart to help you estimate how long an inspection might take based on the home type and add-on services.
| Home Type | Recommended Add-Ons | Duration |
| Under 1,800 sq ft, post-1990 | Radon | 2.5–3 hrs |
| 2,000–3,000 sq ft, 1990–2010 | Radon + sewer | 3–3.5 hrs |
| 3,000+ sq ft | Radon + sewer | 3.5–4+ hrs |
| Pre-1980 home | Radon | Add 30–45 min |
| Home with a crawl space | Moisture testing | Add 20–30 min |
What Factors Increase Home Inspection Cost in Colorado?
Several variables can push a home inspection cost in Colorado. That’s often because they add time to the inspection. Here are a couple of key factors to consider:
- Age: Pre-1980 homes often have dated parts and systems that need additional attention. Inspectors can spend an extra 30–45 minutes inspecting older homes.
- Foundation type: Crawl spaces and pier-and-beam foundations require physical entry and careful inspection of moisture, framing, and supports. Budget an extra 20 to 30 minutes compared to a standard slab-on-grade home.
- Square footage: More square footage means more systems, more rooms, and more roof surface to evaluate.
- Detached structures: Garages, ADUs, and outbuildings are inspected separately from the main home. Each one can add approximately 30 minutes to inspection duration, depending on size and complexity.
- Expansive soil indicators: Denver’s Bentonite clay soils can cause foundation movement. When inspectors spot warning signs, they document the findings carefully and may prompt a recommendation for a structural engineer.
Should I Pay Extra for Radon Testing, Sewer Scopes, or Other Add-Ons?
Radon testing is strongly recommended for nearly every Front Range property. There are 500 deaths in Colorado per year from lung cancer-related issues. The EPA classifies Denver and most surrounding counties as Zone 1 ( the highest radon potential), and roughly 40 to 50% of local homes test above the EPA action level of 4.0 pCi/L. It is the highest-value add-on relative to cost.
Sewer scopes are worth it, particularly for older homes. Clay and Orangeburg pipes in Denver’s older neighborhoods deteriorate predictably over time. A $200 scope can reveal a $10,000+ replacement project.
Frequently Asked Questions
Does homeowners’ insurance or my lender cover the inspection cost?
No. Home inspections are the buyer’s out-of-pocket expense and are not covered by insurance, lenders, or included in closing costs.
Can I negotiate the inspection cost with the seller, or is it always my responsibility?
In Colorado’s standard purchase contract, the buyer pays for inspections. Asking sellers to pay is uncommon and may weaken your offer in competitive Denver markets.
Are there cheaper inspection options for condos or townhomes in Denver?
Condos and townhomes often cost less ($300 to $450) because there is no roof, foundation, or exterior siding to inspect. However, you should still inspect the unit’s HVAC, plumbing, and electrical systems, and request HOA records for building-wide issues.
How do I find a reputable home inspector in Colorado?
Look for inspectors certified through InterNACHI or ASHI, with verifiable Google reviews and same-day digital report delivery. Colorado does not currently require state licensure for home inspectors, so credentials and reputation matter more than in licensed states.
