Quietly, and far from the headlines, the suburban office market continues to strengthen.

In Q2 2017, the office market in the four suburban Philadelphia counties in Pennsylvania achieved their sixth consecutive quarter of positive net absorption - the longest streak since 2008. Occupancy has been rising in an upward trajectory for over four years. The average asking rent for space, which has plateaued over the past year, is at its highest level since 2009. Key to these strengthening fundamentals has been the lack of any significant, new projects.

But it isn't rosy everywhere. Figure 2 shows some of the variation.

On the more positive side, the Main Line continues to be extremely tight for space options, and the bellwether submarket of King of Prussia/Valley Forge has seen occupancy rise for seven consecutive quarters. Meanwhile, the Exton/West Chester submarket has realized a drop in its vacancy rate of 23.8% three years ago to 13.9% in Q2 2017.

Though suffering from higher vacancy, Bucks County has shown considerable improvement recently (see Lower and Central Bucks below). Even Horsham and Fort Washington have driven occupancy higher, compared to last year. Blue Bell as well shouldn't be overlooked, having made some material gains in occupancy.

On the other hand, softer demand for space has been realized over the past year in Bala, Conshohocken, Delaware County, and Plymouth Meeting. These are relatively tight markets for space, though, and nothing alarming seems at play at this point. In a less favorable spot are the Upper Main Line and Jenkintown submarkets, which have seen positive absorption in 2017, but still wrestle with high vacancy and overall flat demand since mid-2016.

The market for trophy office space in the suburbs, near its highest occupancy levels tracked, had a tough quarter, though. Over 114,000 of negative absorption occurred, dropping the occupancy rate for suburban trophy offices slightly to 94.4%. Over the last year, demand has essentially been flat. Nonetheless, asking rents in Q2 2017 reached their highest levels ($35.07 per sq. ft.) this cycle, and occupancy continues to trend upwards.
