Where We Build: Wilmington Districts We Serve

Wilmington is Delaware’s largest city and a major corporate and banking center, thanks to the state’s business-friendly incorporation laws. We work across:

  • The Christina Riverfront – large-scale mixed-use, office, retail, and hospitality redevelopment;
  • The Market Street corridor – retail, restaurant, and mixed-use;
  • The healthcare campuses – hospital and medical-office development;
  • The industrial and I-95 corridors – warehouse, flex, and logistics space.

Permitting and Code in Wilmington

Commercial construction in Wilmington is built to the building code adopted by New Castle County and the local municipality, with environmental review through Delaware’s DNREC where applicable. Its corporate downtown and Riverfront redevelopment shape much of the commercial work here.

  • Adopted building code — International Building Code as adopted locally, with plan review, permitting, and inspections;
  • Riverfront and flood — Christina and Brandywine River flood zones affect low-lying and Riverfront sites;
  • Stormwater and site work — DNREC and county sediment, stormwater, and environmental requirements;
  • Historic and urban-site considerations in the downtown core

We design and build to these from day one so a Wilmington project clears review and performs for the long term.
