Rent office in Wilmington

Office space for rent in Wilmington

Six buildings, two operators

The Wilmington list covers six buildings run by two operators. Downtown, within walking reach of the courts and banks, sit three of them: the Regus floors at 901 N Market Street in the Market Tower and at 1000 North West Street, and The Mill Market West at 221 W 10th Street — the flagship of the state's largest home-grown coworking operator. North of the centre, The Mill Concord works out of the Baynard Building at 3411 Silverside Road, and a new Regus centre at 3301 Lancaster Pike opens in October 2026. The sixth address, Gateway Corporate, is a road-served site on the corridor toward the Pennsylvania line.

What the prices tell you

Published rates exist for the two longest-listed buildings and sit between $390 and $450 per m² a year — a band so tight that little is won by shopping on headline rate alone. The newer centres quote on request, so in practice the money moves in the lease terms: length of commitment, which services are included, and how much of a suite is usable area rather than circulation. Small suites dominate the offer — most listed units are under 50 m², sized for the legal, accounting and holding-company teams of two to eight people that drive demand here.

Office space across Delaware

Wilmington is the hub, but the catalog covers the state's other office markets too: Newark, Delaware — the Regus Christiana Corporate centre at 200 Continental Drive, right off I-95; Dover — the Regus floor at 500 W Loockerman Street, two blocks from Legislative Hall; Seaford — The Mill's southern site at 800 Atlanta Road in Sussex County; and Rehoboth Beach — an oceanfront centre at 511 N Boardwalk.

A business address in Delaware for your LLC

Delaware law requires every LLC and corporation to keep a registered agent with a street address in the state (8 Del. C. § 132) — the agent receives court papers and the state's annual notices. An office or coworking contract from this page gives your company something different: a working business address in Delaware for banks, clients and mail, plus a place to actually work. The two roles do not replace each other. Budget the state's own fees as well: an LLC pays a flat $400 annual tax by June 1, and a corporation files its annual report ($50) with a franchise tax from $175 by March 1.
