Phase 1 Environmental Site Assessment, Appraisal and Closing Costs in BC
Quick answer: Before funding a commercial mortgage, lenders usually require an appraisal by an AACI designated appraiser (about $3,500 to $10,000) and a Phase 1 environmental site assessment to the CSA Z768 standard (about $3,000 to $8,000). Add BC property transfer tax, legal and lender fees, and budget these on top of your down payment. Order the reports early: together they take two to four weeks.

Rough figures. GST may also apply to commercial property; a buyer registered for GST usually self assesses it. A Phase 2 environmental assessment, a building condition report or a broker fee on a private loan would add to this.

How does the appraisal affect your loan?
The lender lends against the lower of the price and the appraised value. For income property the appraiser leans on the income approach: net operating income divided by a market cap rate. If the appraiser uses a higher cap rate than the price implies, the value comes in low and the down payment grows. Check the numbers first with the cap rate and NOI calculator and the commercial mortgage calculator.
How to keep due diligence on schedule
- Write subjects for financing, the Phase 1 and the appraisal into your offer, with enough time: 30 to 45 days is common.
- Ask the seller for any existing environmental reports, leases, rent roll and operating statements on day one.
- Let the lender, through your broker, order the appraisal and confirm the Phase 1 consultant is acceptable to it.
- Budget cash for the down payment and closing costs together; see the commercial down payment guide.

Frequently asked questions
What is a Phase 1 environmental site assessment?
A Phase 1 ESA is a desktop and site review by an environmental consultant that looks for signs of contamination: past uses of the property and its neighbours, records, a site visit and interviews. In Canada it follows the CSA Z768 standard. It does not take soil or water samples.
How much does a Phase 1 environmental assessment cost in BC?
Usually about $3,000 to $8,000, depending on the size of the site and its history. Industrial land, gas stations and auto uses sit at the top of the range. It typically takes two to four weeks.
When does a lender require a Phase 1?
Most commercial lenders require one for industrial, retail, mixed use and many multi unit properties, and always where there has been a gas station, dry cleaner, auto repair or manufacturing on or near the site. The report usually has to be recent and addressed to, or relied on by, the lender.
What happens if the Phase 1 finds a problem?
The consultant recommends a Phase 2, which tests soil and groundwater. If contamination is confirmed, the lender may reduce the loan, require remediation or decline. Building a Phase 1 subject into your offer protects you.
How much does a commercial appraisal cost?
Usually about $3,500 to $10,000 for a lender appraisal by an AACI designated appraiser, and more for large or complex properties. The lender orders it from its approved list, and you pay for it.
What closing costs come with a commercial purchase in BC?
Property transfer tax (1% of the first $200,000, 2% up to $2 million and 3% above that), legal fees, the appraisal, the Phase 1, any building condition report, lender fees, and possibly GST on the purchase.
