Word that Tesla Motors was interested in locating its giant battery factory near Reno apparently jumpstarted a business migration to the region long before the electric car maker made the decision official. The Reno-Sparks industrial market set a record for square footage leased or sold over the past three months - nearly 2.7 million square feet in the third quarter, compared with the previous record of 2.4 million during the same period in 2013, according to NAI Alliance, a Reno-based commercial real estate company.
