Home Inspection Cost Calculator - Base Fee and Add-Ons

Calculator Type

Floor Area In

Square feet Square metres

Only the optional floor area near the bottom uses this. Every fee on this form is money, not a measurement.

Quoted General Inspection ($) *

The headline fee, the one you compared between inspectors.

Radon Test ($)

A 48 hour canister or a continuous monitor. Standard in much of the country and the single most commonly added test.

Sewer Scope ($)

A camera down the lateral. On an older house with mature trees this is the add-on with the largest downside if you skip it.

Termite or WDO Report ($)

Often required by the lender rather than optional, and in some states it must be done by a separately licensed inspector.

Mould Sampling ($)

Air or surface samples sent to a laboratory. Priced per sample as a rule, so ask how many are included.

Well Water Test ($)

Septic Inspection ($)

Pumping the tank to see it properly is usually a separate cost again.

Pool and Spa ($)

Chimney or Fireplace ($)

Thermal Imaging ($)

Asbestos or Lead ($)

Re-Inspection After Repairs ($)

The visit that confirms the seller did what they agreed to. Easy to forget when budgeting and easy to need.

Travel or Distance Fee ($)

Floor Area (optional)

In the unit you chose at the top. Only used to work out the cost per unit of area. Up to 40,000 square feet, or 3,716 square metres.

Purchase Price ($, optional)

Floor Area In

Square feet Square metres

The floor area, the area the base fee covers and the rate above it are all read in whichever you pick, and every figure comes back in it.

Floor Area (sq ft) *

In the unit you chose above. 100 to 40,000 square feet, or 9.3 to 3,716 square metres.

Base Fee ($) *

The starting fee the inspector charges before size is taken into account.

Area the Base Fee Covers (sq ft)

In the same unit as the floor area.

Rate Above That ($ per Unit of Area)

Per square foot, or per square metre if you chose metres. Leave it blank if the inspector does not charge on size; zero means the same thing in both units. A rate of 0.12 a square foot is 1.29 a square metre.
