A building permit is required for construction of any new commercial structure or shell. Residential structures with shared common spaces (i.e. condos, apartments, high/mid-rises) are also processed as commercial new structure or shell permits.

A separate permit is required to complete the interior of a core building. Issuance of a permit for a shell construction does not commit Baltimore County to issue any further permits.
