The office space for eight out of 11 major law firms that signed leases for new D.C. offices between 2011 and 2014 have yet to be filled by replacement tenants, according to data from commercial real estate firm Cushman & Wakefield.

Law firms are the second-largest tenant in Washington after the federal government, and the legal industry’s push to downsize in real estate to save money is leaving a gap in the local real estate market. Those 11 firms shrank, or plan to shrink, an average of 22 percent in square footage when moving to new offices, according to Cushman.

For many of the eight office spaces, the current leases have yet to expire, meaning the firms have signed leases to relocate to new buildings and will continue paying rent at the previous buildings until later this year, 2016 or 2017 — but that new tenants have yet to sign on to move in after they leave.

Two of the largest law firm moves in recent months resulted in significant vacancies that have yet to be filled. Pillsbury , whose previous lease expired in 2014, left behind 160,000 square feet at 2300 N St. NW when it moved to 1200 17th St. NW last month. And Covington & Burling , whose previous lease expires in 2016, left behind 450,000 square feet at 1201 Pennsylvania Ave. NW when it moved to CityCenterDC last month.
