The ground-state phase diagram of the two-leg fermionic dipolar ladder with inter-site Coulomb interactions is studied using density matrix renormalization group (DMRG) techniques. We use a state-of-the-art implementation of the DMRG algorithm and finite size scaling to simulate large system sizes with high accuracy. We also consider two different model systems and explore stable phases in half and quarter filling factors. We find that in the half filling, contrary to the Hubbard model, the charge and spin gaps emerge in a special range of the dipole-dipole and on-site Coulomb interactions. In the quarter filling case, d- and s-wave superconducting states, charge density wave, D-Mott insulating and phase separation phases occur depend on the interaction values.
