Overall vacancy in Calgary’s suburban office market continued to increase in the fourth quarter of 2018, according to analysis by Barclay Street Real Estate. In a report, the company said the vacancy rate rose by 0.1 per cent from the third quarter to finish the year at 19.2 per cent. “Leasing activity was muted as the year drew to a close and with vacancy remaining steady, rental rates also showed stability ability among higher quality properties. Landlords of B and C Class properties have become increasingly motivated to complete leases with less resistance to maintain their tenant bases. Speaking to the latter, the rent expectation gap between owners and tenants has narrowed significantly but with the very low rents we’ve seen during the past 24 months, little room remains for negotiation downward,” said the report.
