HOUSTON—Just how much will companies pay to occupy one of the country's hottest office addresses? According to JLL's 2017 most expensive streets study, which looks at the priciest US office space, those high-profile strips command an average asking rent of $48.65 per square foot, a 46.9% premium compared to the rest of the country. And high rents are no deterrence as only 12.8% of the nation's most expensive real estate is vacant–a full 250 basis points lower than the US average.

While traditional drivers such the financial, law and consulting industries continue to dominate these high-price tag streets such as Fifth and Greenwich Avenues, tech is having a large effect. In fact, five of the top 10 streets in the ranking are tech hubs.

These national addresses have recorded exceptional pre-leasing on new developments, a trend mirrored in Houston. Locally, the most expensive street is Main Street, the only Houston street to make the list. Here, the average full-service office rent is $44.24 per square foot, a 44.8% premium over the market's average asking rent of $30.55 per square foot.
